EASA E R ULES

EASA eRules: aviation rules for the 21st century Rules are the core of the EU civil aviation system. The aim of the EASA eRules project is to make them accessible to stakeholders in an efficient and reliable way.

EASA eRules is a comprehensive, single system for structuring, sharing, and storing of rules. It is the single, easy - access online database for all aviation safety rules applicable to persons and organisations subject to Basic Regulation (Regulation (EU) 2 018/1139).

The Easy Access Rules (EAR) are the output of the eRules project. The EAR books are consolidated versions of those rules, combining EU regulations with the related EASA Executive Director (ED) decisions in an easy - to - read format with advanced navigation features through links and bookmarks.

The EAR books are regularly updated, f ollowing the adoption of an official publication.

The EAR books are available: − in PDF format; − as dynamic online publications (online format) with a wide range of functionalities, such as filters to obtain regulatory material tailored to one’s needs, a search function through the table of contents to quickly access the relevant sections, and easy na vigation for computers, tablets, and mobiles; and − in XML (machine - readable ) format that can be easily processed and automated by recipients, producing output that is compatible and can be synchronised with local applications, search databases, etc.

The EASA eRules system is developed and implemented in close cooperation with the Member States and aviation industry to ensure that all its capabilities are relevant and effective.

GM M.A.201 (e) Responsibilities

ED Decision 2016/011/R The performance of ground de - icing and anti - icing activities does not require a Part - 145 maintenance organisation approval. Nevertheless, inspections required to detect and, when necessary, remove de - icing and/or anti - icing fluid residues are considered maintenance. Such inspections may only be carried out by suitably authorised personnel.

AMC M.A.201(e)(2) Responsibilities

ED Decision 2016/011/R 1. An air carrier licensed in accordance with Regulation (EC) No 1008/2008 only needs to hold a CAMO approval as part of its air operator certificate (AOC) for the management of the continuing airworthiness of the aircraft listed on its AOC. The approval to carry out airwor thiness reviews is optional.

2. Part - M does not provide for CAMOs to be independently approved to perform continuing airworthiness management tasks on behalf of air carriers licensed in accordance with Regulation (EC) No 1008/2008. The approval of such activity is vested in the (AOC).

3. The operator is ultimately responsible and, therefore, accountable for the airworthiness of its aircraft.

AMC1 M.A.201(ea) Responsibilities

ED Decision 2022/017/R HARMONISATION OF THE MANAGEMENT SYSTEMS (a) The harmonised management systems of the organisations that conclude a contract should encompass safety by including the following elements: (1) A forum to share the results and conclusions of the safety review boards (SRBs) of each organisation, which should be attended by the accountable managers, safety managers, and any other relevant nominated person(s). That forum may for example take the form of regular joint meetings of the organisations’ SRBs.

(2) Regular exchange between the organisations of the results and conclusions of the compliance monitoring function as well as of the results of the oversight of each organisation by the CA(s). The exchange of information on compliance monitoring and overs ight provides for awareness, analysis, and hazard identification.

(3) A common or consistent safety policy and its related safety objectives.

Note: establishing common or consistent safety objectives does not prevent the organisation(s) from defining additional and/or specific safety objectives to adapt to the local environment/specificities/operations and/or to the organisation safety performan ce, as applicable.

(4) Common or consistent safety management key processes (see AMC1 CAMO.A.200(a)(3) ‘Management system’ ) that are established by the CAMO and its contracting operators unless those processes relate to activities or procedures that are specific to one of those organisations (e.g. fatigue risk management system (FRMS)).

(5) A cooperation mechanism to ensure prompt reaction when one of the organisations shares some serious concerns with another organisation.

Powered by EASA eRules Page 52 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS (6) A cooperation mechanism to ensure proper actions are coordinated at group level if there are findings at one organisation, which affect the harmonisation of the management systems.

(7) A cooperation mechanism with the operator(s) to manage the changes in the harmonised elements of the management systems in such a way that those changes produce their effect at the same time.

(b) The CAMO/operator(s)’ procedures should describe how the interface and harmonisation between the management systems are achieved, and specify the records to be retained in respect of the harmonisation of the management systems.

AMC2 M.A.201(ea) Responsibilities

ED Decision 2022/017/R To ensure that all parties involved can fulfil their responsibilities, all manuals, procedures, and communication between them should be, at least, in one common language, e.g. English, when the CAMO manages the continuing airworthiness of aircraft registe red in (a) different Member State(s) than its principal place of business. Parties involved include the competent authority(ies) with which that common language should be agreed upon .

ED Decision 2022/017/R HARMONISATION OF THE MANAGEMENT SYSTEMS — GROUP STANDARDS AND CHANGES THERETO (a) Depending on the size of the single air carrier business grouping and on the nature and complexity of its activities, an efficient way of harmonising the management systems of the organisations is by collectively developing group standards that are endorse d by a group management board or similar group governance body. Such group standards may include provisions for the monitoring of the obligations of the parties that have signed the contract established in accordance with Appendix I to Annex I (Part - M) to Regulation (EU) No 1321/2014.

(b) The group management board or similar group governance body is composed of the accountable managers of the organisations and a coordinating member. The names of the board members are included directly, or by reference to a common document, in the contr act, and are updated in the respective document in case of change in personnel.

(c) The coordinating member may be one of the accountable managers or another person. As a consequence of applying point M.A.201(ea) is that several operators will use the same CAMO, the group management board may consider having as coordinating member one employee of that CAMO. The role of the coordinating member includes, but is not limited to the following: − ensuring that all perspectives are considered; − defining the by - laws of the board and ensuring they are complied with; − coordinating decision - making; − ensuring that the documentation is updated; − ensuring the review of the group standards; − ensuring the regular exchange of communication and that meetings take place; and − coordinating the integration of an organisation into, or, if applicable, its departure from, the business grouping.

ED Decision 2022/017/R AIR CARRIER BUSINESS GROUPING (a) In the framework of Regulation (EU) No 1321/2014, ‘a single air carrier business grouping’ means a controlling undertaking and its controlled undertakings. All those undertakings are located in the territory to which the Treaties apply.

The controlling undertaking exercises directly or indirectly a dominant influence over the controlled undertaking by virtue of ownership, financial participation, right to appoint management or a supervisory body, the rules that govern it, or other.

The controlled and controlling undertakings include air carriers licensed in accordance with Regulation (EC) 1008/2008 as well as one or more organisations that are approved in accordance with Annex Vc (Part - CAMO) to Regulation (EU) No 1321/2014.

In the frame of Community - scale groups of undertakings, Article 3 of Directive 2009/38/EC provides additional information about controlling undertakings, which can also be suitable to national - scale groups of undertakings.

(b) Each approved organisation is responsible for its management system, even if they follow common group standards, policies, or procedures. The accountability of each approved organisation, as defined by the relevant EU regulation, is not affected by bei ng part of a single air carrier business grouping. The air carrier remains ultimately responsible for the continuing airworthiness of the aircraft it operates even if the operator decides to contract the continuing airworthiness management to a CAMO. In th at case, the operator is no longer responsible for Regulation (EC) No 1008/2008 of the European Parliament and of the Council of 24 September 2008 on common rules for the operation of air services in the Community (Recast) (OJ L 293, 31.10.2008, p. 3) ( https://eur - lex.europa.eu/legal - content/EN/TXT/?uri=CELEX%3A32008R1008&qid=1660816319207 ).

Alternatively to this pre - flight assessment, when the type of aircraft and nature of operations allow for it, the build - up of residues may be controlled through scheduled maintenance inspection s/cleanings identified in the approved maintenance programme.

2. Tasks such as oil and hydraulic fluid uplift and tyre inflation may be considered as part of the pre - flight inspection. The related pre - flight inspection instructions should address the procedures to determine where the necessary uplift or inflation result s from an abnormal consumption and possibly requires additional maintenance action by the approved maintenance organisation or certifying staff as appropriate.

3. In the case of air carriers licensed in accordance with Regulation (EC) No 1008/2008, the CAMO should publish guidance to maintenance and flight personnel and any other personnel performing pre - flight inspection tasks, as appropriate, defining responsibilities for these actions and, where tasks are contracted to other organisations, how their accomp lishment is subject to the quality system of M.A.712 or the management system required by CAMO.A.200 . It should be demonstrated to the competent authority that pre - flight inspection personnel have received appropriate training for the relevant pre - flight inspection tasks.

GM M.A.301(i) Continuing airworthiness tasks

ED Decision 2023/013/R MAINTENANCE CHECK FLIGHTS (MCFs) (a) The definition of and operational requirements for MCFs are laid down in the Air Operations Regulation and are carried out under the control and responsibility of the aircraft operator.

During the flight preparation, the flight and the post - flight activities as well as for the aircraft handover, the processes requiring the involvement of the maintenance or ganisations or their personnel should be agreed in advance with the operator. The operator should consult as necessary with the CAMO in charge of the airworthiness of the aircraft.

(b) Depending on the aircraft defect and the status of the maintenance activity performed before the flight, different scenarios are possible and are described below: (1) The aircraft maintenance manual (AMM), or any other maintenance data issued by the design approval holder or the declarant of a declaration of design compliance , requires that an MCF be performed before completion of the maintenance ordered. In this scenario, a certificate after incomplete maintenance, when in compliance with M.A.801(f) or 145.A.50(e) , should be issued by the maintenance organisation and the aircraft can be flown for this purpose under its airworthiness certificate. Due to incomplete maintenance, for aircraft used in commercial air transport, it is advisable to open a new entry on the aircraft technical log system to identify the need for an MCF.

This new entry should contain or refer to, as necessary, data relevant to perform the MCF, such as aircraft limitations and any potential effect on operational and emergency equipment due to in complete maintenance, maintenance data reference and maintenance actions to be performed after the flight. After a successful MCF, the maintenance records should be completed, the remaining maintenance actions finalised and the aircraft released to service in accordance with the maintenance organisation’s approved procedures.

(2) Based on its own experience and for reliability considerations and/or quality assurance, an operator or CAMO may wish to perform an MCF after the aircraft has undergone certain maintenance while maintenance data does not call for such a flight. Therefo re, after the maintenance has been properly carried out, a certificate of release to service is issued and the aircraft airworthiness certificate remains valid for this flight.

(3) After troubleshooting of a system on the ground, an MCF is proposed by the maintenance organisation as confirmation that the solution applied has restored the normal system operation. During the maintenance performed, the maintenance instructions are f ollowed for the complete restoration of the system and therefore a certificate of release to service is issued before the flight. The airworthiness certificate is valid for the flight.

An open entry requesting this flight may be recorded in the aircraft te chnical log.

(4) An aircraft system has been found to fail, the dispatch of the aircraft is not possible in accordance with the maintenance data, and the satisfactory diagnosis of the cause of the fault can only be made in flight. The process for this troubleshooting i s not described in the maintenance data and therefore scenario (1) does not apply. Since the aircraft cannot fly under its airworthiness certificate because it has not been released to service after maintenance, a permit to fly issued in accordance with Re gulation (EU) No 748/2012 is Commission Regulation (EU) No 965/2012 of 5 October 2012 laying down technical requirements and administrative procedures rel ated to air operations pursuant to Regulation (EC) No 216/2008 of the European Parliament and of the Council (OJ L 296, 25.10.2012 , p. 1) ( https://eur - lex.europa.eu/legalcontent/EN/TXT/?qid=1568896271265&uri=CELEX:32012R0965 ) .

After the flight and the corresponding maintenance work, the aircraft can be released to service and continue to operate under its original certificate of airworthiness.

(c) For certain MCFs the data obtained or verified in flight will be necessary for assessment or consideration after the flight by the maintenance organisation prior to issuing the maintenance release. For this purpose, when the personnel of the maintenance organisation cannot perform these functions in flight, the maintenance organisation may rely on the crew performing the flight to complete this data or to make statements about in - flight veri fications. In this case, the maintenance organisation should appoint the crew personnel to play such a role on their behalf and, before the flight, brief appointed crew personnel on the scope, functions and the detailed process to be followed, including re quired reporting information after the flight and reporting means, in support of the final release to service to be issued by the certifying staff.

M.A.302 Aircraft maintenance p rogramme

Regulation (EU) 2023/989 (a) Maintenance of each aircraft shall be organised in accordance with an AMP.

(b) The AMP and any subsequent amendments thereto shall be approved by the competent authority.

(c) When the continuing airworthiness of aircraft is managed by a CAMO or CAO, or when there is a limited contract between the owner and a CAMO or CAO concluded in accordance with point M.A.201(i)(3) , the AMP and its amendments may be approved through an indirect approval procedure.

In that case, the indirect approval procedure shall be established by the CAMO or CAO concerned as part of the continuing airworthiness management exposition (‘CAME’) referred to in point CAMO.A.300 of Annex Vc or point M.A.704 of this Annex, or as part of the combined airworthiness exposition (‘CAE’) referred to in point CAO.A.025 of Annex Vd and shall be approved by the competent authority responsible for that CAMO or CAO.

The indirect approval procedure shall only be used when the CAMO or CAO concerned is under the oversight of the Member State of registry of aircraft, unless a written contract has been concluded in accordance with point 3 of point M.1 transferring responsibility for the approval of the aircraft maintenance programme to the competent authority responsible for the CAMO or CAO.

(d) The AMP shall demonstrate compliance with: (1) the instructions issued by the competent authority; (2) the instructions for continuing airworthiness: (i) issued by the holders of the type certificate, restricted type certificate, supplemental type certificate, major repair design approval, ETSO authorisation or the declarant of a declaration of design compliance or the holder of any other relevant appro val issued under Annex I (Part 21) or, as applicable, Annex Ib (Part 21 Light), to Regulation (EU) No 748/2012; (ii) included in the certification specifications referred to in points 21.A.90B or 21.A.431B of Annex I (Part 21) to Regulation (EU) No 748/2012, if applicable; (iii) included in the certification specifications referred to in points 21L.A.62, 21L.A.102, 21L.A.202 or 21L.A.222 of Annex Ib (Part 21 Light) to Regulation (EU) No 748/2012, if applicable; Powered by EASA eRules Page 64 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS (3) the applicable provisions of Annex I (Part - 26) to Regulation (EU) 2015/640 ; (e) By derogation to point (d), the owner or the organisation managing the continuing airworthiness of the aircraft may deviate from the instruction referred to in point (d)(2) and propose escalated intervals in the AMP, based on data obtained from suffici ent reviews carried out in accordance with point (h). Indirect approval is not permitted for the escalation of safety - related tasks. The owner or the organisation managing the continuing airworthiness of the aircraft may also propose additional instruction s in the AMP.

(f) The AMP shall contain details of all maintenance to be carried out, including frequency and any specific tasks linked to the type and specificity of operations.

(g) For complex motor - powered aircraft, when the AMP is based on maintenance steering group logic or on condition monitoring, the AMP shall include a reliability programme.

AMC M.A.302 Aircraft maintenance programme

ED Decision 2023/013/R BASIC PRINCIPLES 1. The term ‘maintenance programme’ is intended to include scheduled maintenance tasks the associated procedures and standard maintenance practises. The term ‘maintenance schedule’ is intended to embrace the scheduled maintenance tasks alone.

2. The aircraft should only be maintained to one approved maintenance programme at a given point in time. Where an owner or operator wishes to change from one approved programme to other, a transfer check or inspection may need to be performed in order to imp lement the change.

3. The details of the maintenance programme should be reviewed at least annually. As a minimum , revisions of documents affecting the programme basis need to be considered by the owner or operator for inclusion in the maintenance programme during the annual review. Applicable mandatory requirements for compliance with Part 21 or Part 21 Light should be incorporated into the aircraft maintenance programme as soon as possible.

4. The aircraft maintenance programme should contain a preface which will define the maintenance programme contents, the inspection standards to be applied, permitted variations to task frequencies and, where applicable, any procedure to manage the evolution of established check or inspection intervals.

5. Repetitive maintenance tasks derived from modifications and repairs should be incorporated into the approved maintenance programme.

6. Appendix I to AMC M.A.302 and AMC M.B.301(b) provide detailed information on the contents of an approved aircraft maintenance programme.

GM M.A.302(a) Aircraft Maintenance Programme

ED Decision 2016/011/R A maintenance programme may indicate that it applies to several aircraft registrations as long as the maintenance programme clearly identifies the effectivity of the tasks and procedures that are not applicable to all of the listed registrations.

AMC M.A.302(d) Aircraft maintenance programme

ED Decision 2023/013/R AMP BASIS AND ASSOCIATED PROGRAMMES 1. An aircraft maintenance programme should normally be based upon the maintenance review board (MRB) report where applicable, the maintenance planning document (MPD), the relevant chapters of the maintenance manual or any other maintenance data containing in formation on scheduling. Furthermore, an aircraft maintenance programme should also take into account any maintenance data containing information on scheduling for components.

2. Instructions issued by the competent authority can encompass all types of instructions from a specific task for a particular aircraft to complete recommended maintenance schedules for certain aircraft types that can be used by the owner/operator directly. These instructions may be issued by the competent authority in the following cases: — in the absence of specific recommendations of the Type Certificate Holder or the declarant of a declaration of design compliance .

— to provide alternate instructions to those described in the subparagraph 1 above, with the objective of providing flexibility to the operator.

3. Where an aircraft type has been subjected to the MRB report process, an operator should normally develop the initial aircraft maintenance programme based upon the MRB report.

4. Where an aircraft is maintained in accordance with an aircraft maintenance programme based upon the MRB report process, any associated programme for the continuous surveillance of the reliability, or health monitoring of the aircraft should be considered a s part of the aircraft maintenance programme.

5. Aircraft maintenance programmes for aircraft types subjected to the MRB report process should contain identification cross reference to the MRB report tasks such that it is always possible to relate such tasks to the current approved aircraft maintenance p rogramme. This does not prevent the approved aircraft maintenance programme from being developed in the light of service experience to beyond the MRB report recommendations but will show the relationship to such recommendations.

6. Some approved aircraft maintenance programmes, not developed from the MRB process, utilise reliability programmes. Such reliability programmes should be considered as a part of the approved maintenance programme.

7. Alternate and/or additional instructions to those defined in points M.A.302(d)(1) and (2) , proposed by the owner or the operator, may include but are not limited to the following: — Escalation of the interval for certain tasks based on reliability data or other supporting information. Appendix I to AMC M.A.302 and AMC M.B.301(b) recommends that the maintenance programme contains the corresponding escalation procedures. The escalation of these tasks is directly approved by the competent authority, except in the case of ALIs (Airworthiness Limitations), which are approved by the Ag ency.

Powered by EASA eRules Page 66 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS — More restrictive intervals than those proposed by the TC holder or the declarant of a declaration of design compliance as a result of the reliability data or because of a more stringent operational environment.

— Additional tasks at the discretion of the operator .

AMC M.A.302(g ) Aircraft maintenance programme

ED Decision 2020/002/R RELIABILITY PROGRAMMES 1. Reliability programmes should be developed for aircraft maintenance programmes based upon maintenance steering group (MSG) logic or those that include condition monitored components or that do not contain overhaul time periods for all significant system components.

2. Reliability programmes need not be developed for aircraft not considered complex motor - powered aircraft or that contain overhaul time periods for all significant aircraft system components.

3. The purpose of a reliability programme is to ensure that the aircraft maintenance programme tasks are effective and their periodicity is adequate.

4. The reliability programme may result in the escalation or deletion of a maintenance task, as well as the de - escalation or addition of a maintenance task 5. A reliability programme provides an appropriate means of monitoring the effectiveness of the maintenance programme.

6. Appendix I to AMC M.A.302 and M.B.301(d) gives further guidance.

GM M.A.305 Aircraft continuing airworthiness record system

ED Decision 2022/011/R (a) The aircraft continuing airworthiness records are the means to assess the airworthiness status of a product and its components. An aircraft continuing airworthiness record system includes the processes to keep and manage those records and should be pro portionate to the subject aircraft. Aircraft continuing airworthiness records should provide the owner/CAO/CAMO of an aircraft with the information needed: (1) to demonstrate that the aircraft is in compliance with the applicable airworthiness requirements; and (2) to schedule all future maintenance as required by the aircraft maintenance programme based, if any, on the last accomplishment of the specific maintenance as recorded in the aircraft continuing airworthiness records.

(b) ‘Applicable airworthiness limitation parameter’ and ‘applicable parameter’ refer to ‘flight hours’ and/or ‘flight cycles’ and/or ‘landings’ and/or ‘calendar time’, and/or any other applicable utilisation measurement unit, as appropriate.

(c) A ‘life - limited part’ is a part for which the maintenance schedule of the aircraft maintenance programme requires the permanent removal from service when, or before, the specified mandatory life limitation in accordance with Commission Regulation (EU) No 748/2012 if any of the applicable parameters is reached.

(d) The ‘current status’ when referring to components of life - limited parts should indicate, for each affected part, the life limitation, the total life accumulated in any applicable parameter (as appropriate) and the remaining life in any applicable param eter before the life limitation is reached.

(e) The term ‘time - controlled components’ embraces any component for which the maintenance schedule of the aircraft maintenance programme requires periodically the removal for maintenance to be performed in an appropriate approved organisation for maintenance in components (workshop) to return the component to a specified standard, the replacement of sub - components of the assembly by new ones, or the inspection or test of component’s performance, after a service period controlled at component level in accordance with the specified airworthiness limitation defined in accordance wit h Commission Regulation (EU) No 7 4 8 / 2012, in any of t he applicable parameters.

(f) The ‘current status’ when referring to time controlled components refers to the current status of compliance with the required periodic maintenance task(s) from the maintenance schedule of the aircraft maintenance programme specific to the time - control led components. It should include the life accumulated by the affected components in the applicable parameter, as appropriate, since the last accomplishment of scheduled maintenance specified in the maintenance schedule of the aircraft maintenance programm e. Any action that alters the periodicity of the maintenance task(s) or changes the parameter of this periodicity should be recorded.

(g) ‘Detailed maintenance records’ in this part refers to those records required to be kept by the person or organisation responsible for the aircraft continuing airworthiness in accordance with M.A.201 in order that they may be able to fulfil their obligations under Part M.

These are only a part of the detailed maintenance records required to be kept by a maintenance organisation under point M.A.614 , CAO.A.090(a) or 145.A.55( a ) . Maintenance organisations are Powered by EASA eRules Page 70 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS required to retain all detailed records to demonstrate that they worked in compliance with their respective requirements and quality procedures.

Not all records need to be transferred from the maintenance organisation to the person or organisation responsible for the aircraft continuing airworthiness in accordance with M.A.201 unless they specifically contain information relevant to aircraft configuration and future maintenance. Thus, incoming certificates of conformity, batch number references and individual task card sign - offs verified by and/or generated by the maintenance o rganisation are not required to be retained by the person or organisation responsible in accordance with M.A.201 . However, dimensional information contained in the task card sign - off or work pack may be requested by the owner/CAO/CAMO in order to verify and demonstrate the effectiveness of the aircraft maintenance programme.

Information relevant to future maintenance may be contained in specific documents related to: − modifications; − airworthiness directives; − repaired and non - repaired damage; − components referred in M.A.305(d) ; and − measurements relating to defects.

(h) An airworthiness limitation is a boundary beyond which an aircraft or a component thereof must not be operated, unless the instruction(s) associated with this airworthiness limitation is (are) complied with.

(i) ‘Other maintenance required for continuing airworthiness’ refers to unscheduled or out - of - phase maintenance due to abnormal or particular conditions or events with an impact on the continuing airworthiness of the aircraft at the time of its return to service. It is not intended to request every single condition described in the maintenance data , e.g. Aircraft Maintenance Manual Chapter 5, but just those that cannot be captured by other means; for example, when they are not included in the records for re pairs. Some abnormal or particular conditions or events that could be kept under this requirement could be lightning strikes, hard landings, long - term storage, propeller or rotor over - speed, over - torque, impact on a main rotor blade, etc.

(j) The term ‘in - service history record’ embraces records from which the current status of life - limited parts can be determined. The ‘in - service history record’ template could be adjusted to the relevant characteristics of the life - limited part, e.g. an en gine disk being different from a fire extinguisher squib or landing gear sliding tube.

Such records document each time a life - limited part is placed in service or removed from service. They should clearly: (1) identify the part by its part number and serial number, (2) show the date of installation and removal (i.e. date on/date off), (3) show the details of the installation and removal (i.e. type, serial number, weight variant, thrust rating, as appropriate, of the aircraft, engine, engine module, or propeller) at installation and removal of the part when this is necessary to appropria tely control the life limitation.

(4) Show the total in - service life accumulated in any applicable parameter, as appropriate, corresponding to the dates of installation and removal of the part.

Powered by EASA eRules Page 71 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS Any other events that would affect the life limitation, such as an embodied modification (in accordance with airworthiness directives, service bulletins or any product improvements) that affects the life limitation or changes the limitation parameter, shou ld also be included in the in - service history record. Not all modifications would necessarily be pertinent to the life limitation of the component. Additionally, if a parameter is not relevant to the life of the part, then that parameter does not need to b e recorded.

(k) The term ‘permanently withdrawn from service’ refers to moving the aircraft or component to a location that is not used for storage and/or future return to service.

(l) The term ‘current status’ refers to the data which accurately establishes the level of compliance of an aircraft, engine, propeller or component thereof, with a requirement. Each status should: (1) identify the aircraft, the engine, the propeller or the component it applies to; ( 2) be dated; and (3) include the relevant total in - service life accumulated in the applicable parameter on the date of the status.

AMC M.A.305(a) Aircraft continuing airworthiness record system

ED Decision 2020/002/R CERTIFICATE OF RELEASE TO SERVICE (a) The inclusion of the certificate of release to service in the aircraft continuing airworthiness record system means that the date and/or any applicable parameter at which the maintenance was performed, including a unique reference to the certificate of release to service, shou ld be processed in the record system .

(b) For components with airworthiness limitations, this information should be found on the authorised release certificate (EASA Form 1 or equivalent). For life - limited parts, some relevant information required by M.A.305 may need to be introduced in the in - service history records.

AMC M.A.305(b)1 Aircraft continuing airworthiness record system

ED Decision 2020/002/R IN - SERVICE LIFE FOR ENGINES, PROPELLERS AND APU’S (a) Some gas turbine engines and propellers are assembled from modules and the total life accumulated in service for the complete engine or propeller may not be kept. When owners and operators wish to take advantage of the modular design, then the total life a ccumulated in service for each module, as well as in - service history if applicable, and detailed maintenance records for each module, should be maintained. The continuing airworthiness records as specified should be kept with the module and should show compliance with any mandatory requirements pertaining to that module.

(b) The recording of in - service life accumulation may be necessary also in other measurement units to ensure the continuing airworthiness of the aircraft. For example, a mandatory life limitation measured in cycles of auxiliary power unit (APU) usage may apply to some rotating parts. In such a case, APU cycles need to be recorded.

GM M.A.305(d)(2) Aircraft continuing airworthiness record system

ED Decision 2023/013/R TASKS CONTROLLED AT COMPONENT LEVEL (a) The maintenance schedule of the aircraft maintenance programme may include tasks controlled at component level coming from a mandatory requ irement in accordance with Part 21 or Part 21 Light and to be performed in a workshop, such as: (1) the removal of a component for periodic restoration to return the component to a specified standard (e.g. removal of the landing gear for overhaul); (2) the periodic removal of a component for replacement of a sub - component by a new one when it is not possible to restore the item to a specific standard of failure resistance (e.g.

discarding of universal joints of a gearbox, batteries of the escape slide/ra ft, discharge cartridges of fire extinguishers, etc.); and (3) a periodic inspection or test to confirm that a component meets specified performance standards (e.g. functional check of the portable emergency locator transmitter, etc.). The component is left in service (no further maintenance action taken) on the condi tion that it continues to fulfil its intended purpose within specified performance limits until the next scheduled inspection.

The above tasks apply to ‘time - controlled components’ as defined in paragraph (e) of GM M.A.305 . If a component affected by a task in accordance with (2) and (3) above is controlled at aircraft level by the aircraft maintenance programme and it has not been removed since the task was last accomplished, then its status of compliance with M.A.305(d)2 is already demonstrated by the aircraft records.

Note: The maintenance in accordance: − with (1) and (2) above assumes a predictable deterioration of the component: the overall reliability invariably decreases with age; and − with (3) assumes a gradual deterioration of the component: failure resistance can reduce and drop below a defined level.

(b ) When a component is affected by a maintenance task contained in the aircraft maintenance programme (AMP) that is recommended by the design approval holder (DAH) or the declarant of a declaration of design compliance and controlled at component level, although such component does not qualify as a time - controlled component, the status of the component may be needed to show that all the maintenance due on the aircraft according to the aircraft maintenance programme has b een carried out. There is no specifi c requirement to keep the EASA Form 1 or equivalent or any other detailed maintenance records.

(c) For aircraft maintenance programmes developed under a primary maintenance process - oriented methodology (e.g. Maintenance Steering Group), the term ‘time - controlled component’ pertains to ‘Hard Time’ and ‘On - Condition’. The primary maintenance processes are: (1) Hard Time This is a preventive process in which known deterioration of a component is limited to an acceptable level by the maintenance actions which are carried out at periods related to time in service (e.g. calendar time, number of cycles, number of landings). The prescribed actions restore the component utility margin to the applicable time limitation.

Powered by EASA eRules Page 76 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS (2 ) On - Condition It is a preventive process in which the component is inspected or tested, at specified periods, to an appropriate standard in order to determine whether it can continue in service. The purpose is to remove the component before its failure in service.

(3) Condition Monitoring This is a process in which a parameter of a condition in a component (vibration, temperature, oil consumption, etc.) is monitored to identify the development of a fault.

The purpose is to remove the component before its failure in service (e.g. due to rela ted repair costs), but they are permitted to remain in service without preventive maintenance until a functional failure occurs.

Note: For components that are not subject to any of these primary maintenance processes, corrective maintenance is carried out after failure detection and is aimed at restoring components to a condition in which they can perform their intended function (‘f ly - to failure’).

(d) The following table provides a summary of the records’ requirements related to components subjected to primary maintenance process, including components without an EASA Form 1 in accordance with point 21.A.307 (c) of Part 21 or point 21L.A.193(c) of Part 21 Light : Primary maintenance Continuing airworthiness records process − Current status (M.A.305(d)(1)); − In - service history record (M.A.305(e)(3)(i)); Life - limited − EASA Form 1 and detailed maintenance records for last part scheduled maintenance and subsequent unscheduled maintenance (M.A.305(e)(3)(ii)), including modifications and repairs (M.A.305(e)(2)(ii)).

Hard time − Current status (M.A.305(d)(2)); − EASA Form 1 and detailed maintenance records for last scheduled maintenance and subsequent unscheduled maintenance (M.A.305(e)(3)(ii)), including modifications and repairs (M.A.305(e)(2)(ii)).

On condition − Current status (M.A.305(d)(2)); and Time - − EASA Form 1 and detailed maintenance records for last controlled scheduled maintenance and subsequent unscheduled component maintenance (M.A.305(e)(3)(ii)) If the task is controlled at aircraft level, the above information could be already contained in the records related to the aircraft maintenance programme ( M.A.305 (c)(3) and M.A.305 (e)(2)(iii)). If the maintenance was performed off wing, the EASA Form 1 needs to be kept.

AMC M.A.305(e) Aircraft continuing airworthiness record system

ED Decision 2020/002/R INFORMATION TECHNOLOGY (IT) SYSTEMS AND FORM OF RECORDS (a) The information that constitutes the aircraft continuing airworthiness records may be entered in an information technology (IT) system and/or documents equivalent in scope and detail.

IT systems acceptable for supporting the aircraft continuing airworthiness records should: (1) include functions so that search of data and production of status is possible; (2) allow a transfer of the aircraft continuing airworthiness records data from one system to another using an industry - wide/worldwide data format or allow printing information; (3) contain safeguards which prevent unauthorised personnel from altering data; and (4) ensure the integrity of the data, including traceability of amendments.

(b) ‘Data equivalent in scope and detail’ are included in the airworthiness record system and could be an aircraft logbook, engine logbook(s) or engine module log cards, propeller logbook(s) and log cards for life - limited parts.

Any logbook/log card should contain: (1) identification of the product or component it refers to; (2) type, part number, serial number and registration, as appropriate, of the aircraft, engine, propeller, engine module, or component to which the component has been fitted in, along with the reference to the installation and removal; (3) the date and the corresponding total in - service life accumulated in any applicable parameter unit, as appropriate; and (4) any AD, modification, repair, maintenance or deferred maintenance tasks applicable.

When fulfilling the applicable requirements, a logbook/log card as described above could be a means to comply with the current status and the in - service history record for each life - limited part.

(c) Form of records Producing and/or keeping continuing airworthiness records in a form acceptable to the competent authority normally means in either material/physical or electronic state, or a combination of both.

Retention of records should be done in one of the following formats: (1) original paper document or electronic data (via an approved electronically signed form); (2) a paper reproduction of a paper document (original or copy); or (3) an electronic reproduction of electronic data (original or copy); or (4) a printed reproduction of electronic data (original or copy); or (5) an electronically digitised reproduction of a paper document (original or copy); or (6) a microfilm or scanned reproduction copy of a paper document (original or copy).

Where IT systems are used to retain documents and data, it should be possible to print a paper version of the documents and data kept.

(d) Physical (non - digitised) records Powered by EASA eRules Page 78 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS All physical records should remain legible throughout the required retention period. Physical records on either paper or microfilm systems should use robust material, which can withstand normal handling, filing and ageing. They should be stored in a safe w ay with regard to damage, alteration and theft.

(e) Digitised records Digitised records may be created from a paper document (original or copy) or from electronic data.

When created from a paper document: (1) the creation date of the digitised record should be stored with the digitised record; (2) it is advisable to create an individual digitised record for each document; (3) if an organisation creates a large number of digitised records, the use of database technology should ease the future retrieval of the record; and (4) digitised records should be legible, including details such as, but not limited to, the date of signature, names, stamps, notes, or drawings.

(f) Digitised record retention Digitised records when created from an original paper record, or as a digital electronic original, should be stored on a system which is secured and kept in an environment protected from damage (e.g. fire, flooding, excessive temperature or accidental eras ing). IT systems should have at least one backup system, which should be updated at least within 24 hours of any entry in the primary system. Access to both primary and backup systems is required to be protected against the ability of unauthorised personne l to alter the database and they should preferably be located remotely from the main system.

The system used for retention of digitised records should: (1) ensure the integrity, accuracy and completeness of the record; (2) ensure that access to the digitised record has safeguards against alteration of the data; (3) ensure the authenticity of the record including assurance that the date has not been modified after creation; (4) be capable of retrieving individual records within a reasonable time period; and (5) be maintained against technological obsolescence which would prevent printing, displaying or retrieval of the digitised records.

Computer backup discs, tapes etc. should be stored in a different location from that containing the current working discs, tapes, etc. and in a safe environment.

Where the competent authority has accepted a system for digitised record - keeping satisfying the above, the paper document may be permanently disposed of.

(g) Lost or destroyed records Reconstruction of lost or destroyed records can be done by reference to other records which reflect the time in service, research of records maintained by maintenance organisations and reference to records maintained by individual mechanics, etc. When reco nstruction has been done and the record is still incomplete, the owner/operator may make a statement in the new record describing the loss and establishing the time in service based on the research and the best estimate of time in service. The reconstructe d records should be submitted to the Powered by EASA eRules Page 79 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS competent authority for acceptance.

M.A.306 Aircraft technical log system

Regulation (EU) 20 20 / 270 (a) In addition to the requirements of point M.A.305 , for CAT, commercial specialised operations and commercial ATO or commercial DTO operations, the operator shall use a technical log system containing the following information for each aircraft: 1. information about each flight, necessary to ensure continued flight safety, and; 2. the current aircraft certificate of release to service, and; 3. the current maintenance statement giving the aircraft maintenance status of what scheduled and out of phase maintenance is next due except that the competent authority may agree to the maintenance statement being kept elsewhere, and; 4. all outstanding deferred defects rectifications that affect the operation of the aircraft, and; 5. any necessary guidance instructions on maintenance support arrangements.

(b) The initial issue of aircraft technical log system shall be approved by the competent authority specified in point CAMO.A.105 of Annex Vc (Part - CAMO), or point M.1 of this Annex (Part - M) or point CAO.1(1) of Annex Vd (Part - CAO), as applicable. Any subsequent amendment to that system shall be managed in accordance with point CAMO.A.300(c) , or points M.A.704(b) and (c), or point CAO.A.025(c) .

AMC M.A.306(a) Aircraft technical log system

ED Decision 2020/002/R CONTENT OF INFORMATION ON THE ATL SYSTEM For CAT operations, commercial specialised operations and commercia l ATO or commercial DTO operations, the aircraft technical log is a system for recording defects and malfunctions during the aircraft operation and for recording details of all maintenance carried out on an aircraft between scheduled base maintenance visits. In addition, it is used for recording flight safety and maintenance informa tion the operating crew need to know.

Cabin or galley defects and malfunctions that affect the safe operation of the aircraft or the safety of its occupants are regarded as forming part of the aircraft log book where recorded by another means.

The aircraft technical log system may range from a simple single section document to a complex system containing many sections but in all cases it should include the information specified for the example used here which happens to use a 5 section document / c omputer system: Section 1 should contain details of the registered name and address of the operator the aircraft type and the complete international registration marks of the aircraft.

Powered by EASA eRules Page 81 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS Section 2 should contain details of when the next scheduled maintenance is due, including, if relevant any out of phase component changes due before the next maintenance check. In addition this section should contain the current certificate of release to service (C RS), for the complete aircraft, issued normally at the end of the last maintenance check.

NOTE: The flight crew do not need to receive such details if the next scheduled maintenance is controlled by other means acceptable to the competent authority.

Section 3 should contain details of all information considered necessary to ensure continued flight safety. Such information includes: (i) the aircraft type and registration mark, (ii) the date and place of take - off and landing, (iii) the times at which the aircraft took off and landed, (iv) the running total of flying hours, such that the hours to the next schedule maintenance can be determined. The flight crew does not need to receive such details if the next scheduled maintenance is controlled by other means acceptable to the competent auth ority.

(v) details of any failure, defect or malfunction to the aircraft affecting airworthiness or safe operation of the aircraft including emergency systems, and any failure, defect or malfunctions in the cabin or galleys that affect the safe operation of the aircr aft or the safety of its occupants that are known to the commander. Provision should be made for the commander to date and sign such entries including, where appropriate, the nil defect state for continuity of the record.

Provision should be made for a CRS following rectification of a defect or any deferred defect or maintenance check carried out. Such a certificate appearing on each page of this section should readily identify the defect(s) to which it relates or the particular maintenance check as app ropriate.

In the case of maintenance performed by a Part - 145 maintenance organisation, i t is acceptable to use an alternate abbreviated certificate of release to service consisting of the statement ‘ Part - 145 release to service’ instead of the full certification statement specified in AMC 145.A.50(b) paragraph 1. When the alternate abbreviated certificate of release to service is used, the introductory section of the technical log should include an example of the full certification statement from AMC 145.A.50(b) paragraph 1.

(vi) the quantity of fuel and oil uplifted and the quantity of fuel available in each tank, or combination of tanks, at the beginning and end of each flight; provision to show, in the same units of quantity, both the amount of fuel planned to be uplifted and the amount of fuel actually uplifted; provision for the time when ground de - icing and/or anti - icing was started and the type of fluid applied, incl uding mixture ratio fluid/water and any other information required by the operator's procedures in order to allow the assessment on whether inspections for and/or elimination of de - icing/anti - icing fluid residues that could endanger flight safety are requi red.

(vii) the pre - flight inspection signature.

In addition to the above, it may be necessary to record the following supplementary information: − the time spent in particular engine power ranges where use of such engine power affects the life of the engine or engine module; − the number of landings where landings affect the life of an aircraft or aircraft component; − flight cycles or flight pressure cycles where such cycles affect the life of an aircraft or aircraft component.

NOTE 2: Section 3 should be designed so that one copy of each page may remain on the aircraft and one copy may be retained on the ground until completion of the flight to which it relates.

NOTE 3: Section 3 layout should be divided to show clearly what is required to be completed after flight and what is required to be completed in preparation for the next flight.

Section 4 should contain details of all deferred defects that affect or may affect the safe operation of the aircraft and should therefore be known to the aircraft commander. Each page of this section should be pre - printed with the operator’s name and page serial n umber and make provision for recording the following: (i) a cross reference for each deferred defect such that the original defect can be identified in the particular section 3 sector record page.

(ii) the original date of occurrence of the defect deferred.

(iii) brief details of the defect.

(iv) details of the eventual rectification carried out and its CRS or a clear cross - reference back to the document that contains details of the eventual rectification.

Section 5 should contain any necessary maintenance support information that the aircraft commander needs to know. Such information would include data on how to contact maintenance if problems arise whilst operating the routes etc.

AMC M.A.401(c) Maintenance data

ED Decision 2015/029/R 1. Data being made available to personnel maintaining aircraft means that the data should be available in close proximity to the aircraft or component being maintained, for mechanics and certifying staff to perform maintenance.

2. Where computer systems are used, the number of computer terminals should be sufficient in relation to the size of the work programme to enable easy access, unless the computer system can produce paper copies. Where microfilm or microfiche readers/printers are used, a similar requirement is applicable.

3. Maintenance tasks should be transcribed onto the work cards or worksheets and subdivided into clear stages to ensure a record of the accomplishment of the maintenance task. Of particular importance is the need to differentiate and specify, when relevant, d isassembly, accomplishment of task, reassembly and testing. In the case of a lengthy maintenance task involving a succession of personnel to complete such task, it may be necessary to use supplementary work cards or worksheets to indicate what was actua lly accomplished by each individual person.

AMC M.A.402(d) Performance of maintenance

ED Decision 2016/011/R When performing maintenance, personnel are required to use the tools, equipment and test apparatuses necessary to ensure completion of work in accordance with accepted maintenance and inspection standards. Inspection, service or calibration that is perform ed on a regular basis should be performed in accordance with the equipment manufacturers’ instructions. All tools requiring calibration should be traceable to an acceptable standard.

In this context, ‘officially recognised standards’ means those standards established or published by an official body, being either a natural or legal person, and which are widely recognised by the air transport sector as constituting good practice.

If the organisation responsible for the type design involved recommends special equipment or test apparatuses, personnel should use the recommended equipment or apparatuses or equivalent equipment accepted by the competent authority.

All work should be performed using materials of such quality and in such a manner that the condition of the aircraft or its components after maintenance is at least equal to its or their original or modified condition (with regard to aerodynamic function, structural strength, resistance to vibration, deterioration and any other qualities affecting airworthiness).

AMC M.A.402(e ) Performance of maintenance

ED Decision 2016/011 /R The working environment should be appropriate for the maintenance task being performed such that the effectiveness of personnel is not impaired.

(a) Temperature should be maintained such that personnel can perform the required tasks without undue discomfort.

(b) Airborne contamination (e.g. dust, precipitation, paint particles, filings) should be kept to a minimum to ensure aircraft/components surfaces are not contaminated, if this is not possible all susceptible systems should be sealed until acceptable condition s are re - established.

(d) Noise levels should not be allowed to rise to the level of distraction for inspection staff or if this is not possible inspection staff should be provided with personnel equipment to reduce excessive noise.

AMC M.A.402(f) Performance of maintenance

ED Decision 2016/011/R Facilities should be provided appropriate for all planned maintenance. This may require aircraft hangars that are both available and large enough for the planned maintenance.

Aircraft component workshops should be large enough to accommodate the components that are planned to be maintained.

Protection from inclement weather means the hangar or component workshop structures should be to a standard that prevents the ingress of rain, hail, ice, snow, wind and dust etc.

AMC M.A.402(g) Performance of maintenance

ED Decision 2016/011/R (a) To minimise the risk of multiple errors and to prevent omissions, the person or organisation performing maintenance should ensure that: (1) every maintenance task is signed off only after completion; (2) the grouping of tasks for the purpose of sign - off allows critical steps to be clearly identified; and (3) any work performed by personnel under supervision (i.e. temporary staff, trainees) is checked and signed off by an authorised person.

(b) To minimise the possibility of an error being repeated in identical tasks that involve removal/installation or assembly/disassembly of several components of the same type fitted to more than one system, whose failure could have an impact on safety, the person or orga nisation performing maintenance should plan different persons to perform identical tasks in different systems. However, when only one person is available, then this person should perform reinspection of the tasks as described in AMC2 M.A.402(h) .

AMC1 M.A.402(h) Performance of maintenance

ED Decision 2016/011/R CRITICAL MAINTENANCE TASKS The following maintenance tasks should primarily be reviewed to assess their impact on safety: (a) tasks that may affect the control of the aircraft, flight path and attitude, such as installation, rigging and adjustments of flight controls; (b) aircraft stability control systems (autopilot, fuel transfer); (c) tasks that may affect the propulsive force of the aircraft, including installation of aircraft engines, propellers and rotors; and (d) overhaul, calibration or rigging of engines, propellers, transmissions and gearboxes.

AMC2 M.A.402(h) Performance of maintenance

ED Decision 2016/011/R INDEPENDENT INSPECTION (a) What is an independent inspection Independent inspection is one possible error - capturing method. It consists of an inspection performed by an ‘independent qualified person’ of a task carried out by an ‘authorised person’, taking into account that: (1) the ‘authorised person’ is the person who performs the task or supervises the task and assumes the full responsibility for the completion of the task in accordance with the applicable maintenance data; (2) the ‘independent qualified person’ is the person who performs the independent inspection and attests the satisfactory completion of the task and that no deficiencies have been found. The ‘independent qualified person’ does not issue a certificate of releas e to service, therefore he/she is not required to hold certification privileges; Powered by EASA eRules Page 90 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS (3) the certificate of release to service is issued by the ‘authorised person’ after the independent inspection has b een carried out satisfactorily; (4) the work card system should record the identification of each person, the date and the details of the independent inspection, as necessary, before the certificate of release to service is issued.

(b) Qualifications of personnel performing independent inspections (1) When the work is performed by a Part - M Subpart F organisation, then the organisation should have procedures to demonstrate that the ‘independent qualified person’ has been trained and has gained experience in the specific control systems to be inspected. This training and experience could be demonstrate d, for example, by: (i) holding a Part - 66 licence in the same subcategory as the licence subcategory or equivalent necessary to release or sign off the critical maintenance task; (ii) holding a Part - 66 licence in the same category and specific training in the task to be inspected; or (iii) having received appropriate training and having gained relevant experience in the specific task to be inspected.

(2) When the work is performed outside a Part - M Subpart F organisation: (i) the ‘independent qualified person’ should hold: (A) a Part - 66 licence in any category or an equivalent national qualification when national regulations apply; or (B) a valid pilot licence for the aircraft type issued in accordance with European Union regulations or an equivalent national qualification when national regulations apply; (ii) additionally, the ‘authorised person’ should assess the qualifications and experience of the ‘independent qualified person’ taking into account that the ‘independent qualified person’ should have received training and have experience in the particular task . It should not be acceptable that the ‘authorised person’ shows to the ‘independent qualified person’ how to perform the inspection once work has been already finalised.

(c) How should independent inspection be performed Independent inspection should ensure for example correct assembly, locking and sense of operation. When inspecting control systems that have undergone maintenance, the ‘independent qualified person’ should consider the following points independently: (1) all those parts of the system that have actually been disconnected or disturbed should be inspected for correct assembly and locking; (2) the system as a whole should be inspected for full and free movement over the complete range; (3) cables should be tensioned correctly with adequate clearance at secondary stops; (4) the operation of the control system as a whole should be observed to ensure that the controls are operating in the correct sense; (5) if different control systems are interconnected so that they affect each other, all the interactions should be checked through the full range of the applicable controls; and Powered by EASA eRules Page 91 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS (6) software that is part of the critical maintenance task should be checked, for example version and compatibility with the aircraft configuration.

(d) What to do in unforeseen cases when only one person is available REINSPECTION: (1) Reinspection is subject to the same conditions as the independent inspection is, except that the ‘authorised person’ performing the maintenance task is also acting as ‘independent qualified person’ and performs the inspection.

(2) For critical maintenance tasks, reinspection should only be used in unforeseen circumstances when only one person is available to carry out the task and perform the independent inspection. The circumstances cannot be considered unforeseen if the person or organisation has not assigned a suitable ‘independent qualified person’ to that particular task.

(3) The certificate of release to service is issued by the ‘authorised person’ after the reinspection has been performed satisfactorily.

(4) The work card system should record the identification of the ‘authorised person’ and the date and the details of the reinspection, as necessary, before the certificate of release to service is issued.

GM M.A.402(h) Performance of maintenance

ED Decision 20 23/013/R Several data sources may be used for the identification of critical maintenance tasks, such as: − information from the design approval holder or the declarant of a declaration of design compliance ; − accident reports; − investigation and follow - up of incidents; − occurrence reporting; − flight data analysis; − results of audits; − normal operations monitoring schemes; − feedback from training; and − information exchange systems.

(b) Only the certifying staff referred to in point M.A.801(b)(1) or in Subpart F of this Annex or in Annex II (Part - 145) or in Annex Vd (Part - CAO) , or the person authorised in accordance with point M.A.801(c) of this Annex can decide, using maintenance data referred to in point M.A.401 of this Annex, whether an aircraft defect hazards seriously the flight safety and therefore decide when and which rectification action shall be taken before further flight and which defect rectification can be deferred. However, this does not apply when t he MEL is used by the pilot or by the certifying staff.

(c) Any aircraft defect that would not hazard seriously the flight safety shall be rectified as soon as practicable, after the date the aircraft defect was first identified and within any limits specified in the maintenance data or the MEL.

(d) Any defect not rectified before flight shall be recorded in the aircraft continuing airworthiness record system referred to in point M.A.305 or, if applicable in the aircraft technical log system referred to in point M.A.306 .

AMC M.A.403(b) Aircraft defects

ED Decision 2015/029/R An assessment of both the cause and any potentially hazardous effect of any defect or combination of defects that could affect flight safety should be made in order to initiate any necessary further investigation and analysis necessary to identify the root cause of the defect.

AMC M.A.403(d) Aircraft defects

ED Decision 2015/029/R All deferred defects should be made known to the pilot/flight crew, whenever possible, prior to their arrival at the aircraft.

Deferred defects should be transferred on to worksheets at the next appropriate maintenance check, and any deferred defect which is not rectified during the maintenance check, should be re - entered on to a new deferred defect record sheet. The original date of the defect should be retained.

The necessary components or parts needed for the rectification of defects should be made available or ordered on a priority basis, and fitted at the earliest opportunity.

AMC M.A.502 Component maintenance

ED Decision 2015/029/R Component removal from and installation on an aircraft is considered to be aircraft maintenance and not component maintenance. As a consequence, M.A.502 requirements do not apply to this case.

AMC M.A.502(b) and (c) Component maintenance

ED Decision 2020/002/R M.A.502(b) and (c) allow the performance of certain component maintenance, in accordance with component maintenance data, to maintenance organisations not holding the corresponding B/C rating and to independent certifying staf f, subject to the agreement of: − The authority responsible for the oversight of the maintenance organisation (refer to M.1 , paragraph 2 for M.A. Subpart F maintenance organisations, or to 145.1 for Part - 145 maintenance organisations , or to CAO.1 for Part - CAO maintenance organisations) or , − The authority of the Member State of registry in the case of maintenance performed by indepe ndent certifying staff.

This should only be permitted by the competent authority in the case of simple component maintenance, where the competent authority is satisfied that the certifying staff are appropriately qualified and the proper tooling and facilities are available. It i s important to note that for more complex component maintenance, special qualifications may be required and it is not enough with holding a Part - 66 aircraft maintenance licence.

GM1 M.A.502(e) Component maintenance

ED Decision 2021/009/R A ‘declaration of maintenance accomplished’ is a certificate prepared in any shape/form by the person or organisation that performed any maintenance on the component covered by the certificate and subject to the conditions in M.A.502(e) . This person or organisation does not need an approval to perform maintenance in accordance with Regulation (EU) No 1321/2014. In order for the component to be eligible for installation with a ‘declaration of maintenance accomplished’, this declaration, t ogether with other records, should allow the determination that the component was first installed as ‘new’, as a component referred to in M.A.502(e) . Such a component should not be installed in an aircraft if there is information on the certificate which is not readable or not understandable or states that the component is not in a satisfactory condition for operation.

M.A.503 Life - limited parts and time - controlled components

Regulation (EU) 20 20 / 270 (a) Installed life - limited parts and time - controlled components shall not exceed the approved limitation as specified in the AMP and ADs, except as provided for in point M.A.504(b) .

(b) When the approved limitation expires, the component shall be removed from the aircraft for maintenance, or for disposal in the case of life - limited parts.

M.A.504 Segregation of components

Regulation (EU) 2019/1383 (a) Unserviceable and unsalvageable components shall be segregated from serviceable components, standards parts and materials.

(b) Unsalvageable components shall not be permitted to re - enter the component supply system unless the mandatory life limitation has been extended or a repair solution has been approved in accordance with Regulation (EU) No 748/2012.

AMC1 M.A.504 Segregation of components

ED Decision 2020/002/R (a) Unserviceable components should be identified and stored in a separate secure location that is managed by the maintenance organisation until a decision is made on the future status of such components. Certifying staff outside maintenance organisations ( M.A.801(b)(1 ) , or M.A.801(c) ) that release aircraft maintenance should send, with the agreement of the aircraft owner/lessee, any unserviceable component to a maintenance organisation for controlled storage.

Nevertheless, the person or organisation that declared the component unservi ceable may transfer its custody, after identifying it as unserviceable, to the aircraft owner/lessee provided that such transfer is reflected in the aircraft logbook, or engine logbook, or component logbook.

(b) ‘Secure location under the control of an approved maintenance organisation’ refers to a location that is managed by the approved maintenance organisation that prevents the component from being reused or tampered with. This may include facilities that a re established by the organisation at locations different from the main maintenance facilities. These locations should be identified in the relevant procedures of the organisation.

(c) In the case of unsalvageable components, the person or organisation should: (1) retain such components in the secure location referred to in paragraph (b); (2) arrange for the component to be mutilated in a manner that ensures that it is cannot be restored for use, before disposing it; or (3) mark the component indicating that it is unsalvageable, when, in agreement with the component owner, the component is disposed of for legitimate non - flight uses (such as training and education aids, research and development), or for non - aviation applic ations, mutilation is often not appropriate. Alternatively to marking, the original part number or data plate information can be removed, or a record kept of the disposal of the component for legitimate non - flight uses.

GM1 M.A.504 Segregation of components

ED Decision 2019/009/R MUTILATION OF COMPONENTS (a) Mutilation should be accomplished in such a manner that the components become permanently unusable for their originally intended use. Mutilated components should not be able to be reworked or camouflaged to provide the appearance of being serviceable, such as by replating, shortening and rethreading long bolts, welding, straightening, machining, cleaning, polishing, or repainting.

AMC M.A.603(c) Extent of approval

ED Decision 2015/029/R 1. The agreement by the competent authority for the fabrication of parts by the approved maintenance organisation should be formalised through the approval of a detailed procedure in the maintenance organisation manual. This AMC contains principles and condit ions to be taken into account for the preparation of an acceptable procedure.

2. Fabrication, inspection, assembly and test should be clearly within the technical and procedural capability of the approved maintenance organisation.

3. The approved data necessary to fabricate the part are those approved either by the Agency, the TC holder, Part - 21 design organisation approval holder, or STC holder.

4. Items fabricated by an approved maintenance organisation may only be used by that organisation in the course of overhaul, maintenance, modifications, or repair of aircraft or components undergoing work within its own facility. The permission to fabricat e does not constitute approval for manufacture, or to supply externally and the parts do not qualify for Powered by EASA eRules Page 104 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS certification on EASA Form 1 . This also applies to the bulk transfer or surplus inventory, in that locally fabricated parts are physically segregated and excluded from any delivery certification.

5. Fabrication of parts, modification kits etc. for onward supply and/or sale may not be conducted under a M.A. Subpart F approval.

6. The data specified in paragraph 3 may include repair procedures involving the fabrication of parts. Where the data on such parts is sufficient to facilitate fabrication, the parts may be fabricated by an approved maintenance organisation. Care should be taken to ensure that the data include details of part numbering, dimensions, materials, processes, and any special manufacturing techniques, special raw material specification or/and incoming inspection requirement and that the approved organisation has t he necessary capability. That capability should be defined by way of maintenance organisation manual content. Where special processes or inspection procedures are defined in the approved data which are not available at the approved maintenance organisation , that organisation cannot fabricate the part unless the TC/STC holder gives an approved alternative.

7. Examples of fabrication under the scope of an M.A. Subpart F approval can include but are not limited to the following: (a) fabrication of bushes, sleeves and shims, (b) fabrication of secondary structural elements and skin panels, (c) fabrication of control cables, (d) fabrication of flexible and rigid pipes, (e) fabrication of electrical cable looms and assemblies, (f) formed or machined sheet metal panels for repairs.

Note: It is not acceptable to fabricate any item to pattern unless an engineering drawing of the item is produced which includes any necessary fabrication processes and which is accepted to the competent authority.

8. Where a TC holder or an approved production organisation is prepared to make available complete data which is not referred to in aircraft manuals or service bulletins but provides manufacturing drawings for items specified in parts lists, the fabricatio n of these items is not considered to be within the scope of an M.A. Subpart F approval unless agreed otherwise by the competent authority in accordance with a procedure specified in the maintenance organisation manual.

9. Inspection and Identification.

Any locally fabricated part should be subject to an inspection stage before, separately, and preferably independently from, any inspection of its installation. The inspection should establish full compliance with the relevant manufacturing data, and the part should be unambiguously identified as fit for use by stating conformity to the approved data. Adequate records should be maintained of all such fabrication processes including heat treatment and the final inspections. All parts, excepting those with inadequate space, should carry a part number which clearly relates it to the manufacturing/inspection data. Additional to the part number the approve d maintenance organisation’s identity should be marked on the part for traceability purposes.

2. The maintenance organisation exposition as specified in Part - 145 provides an outline of the format of an acceptable maintenance organisation manual for larger organisations with more than 10 maintenance staff, dependent upon the complexity of the organisation.

M.A.605 Facilities

Regulation (EU) No 1321/2014 The organisation shall ensure that: (a) Facilities are provided for all planned work, specialised workshops and bays are segregated as appropriate, to ensure protection from contamination and the environment.

(b) Office accommodation is provided for the management of all planned work including in particular, the completion of maintenance records.

Powered by EASA eRules Page 106 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS (c) Secure storage facilities are provided for components, equipment, tools and material. Storage conditions shall ensure segregation of unserviceable components and material from all other components, material, equipment and tools. Storage conditions shall be in accordance with the manufacturers' instructions and access shall be restricted to authorised personnel.

AMC M.A.605(a) Facilities

ED Decision 2020/002/R 1. Where a hangar is not owned by the M.A. Subpart F organisation, it may be necessary to establish proof of tenancy. In addition, sufficiency of hangar space to carry out planned maintenance should be demonstrated by the preparation of a projected aircraft hangar visit plan relative to the aircraft mainten ance programme. The aircraft hangar visit plan should be updated on a regular basis.

For balloons and airships , a hangar may not be required where maintenance of the envelope and bottom end equipment can more appropriately be performed outside, providing all necessary maintenance can be accomplished in accordance with M.A.402 or ML.A.402 . For complex repairs or component maintenance requiring an EASA Form 1 , suitable approved workshops should be provided. The facilities and environmental conditions required for inspection and maintenance should be defined in the Maintenance Organisation Manual.

Depending on the scope of work of the maintenance organisation, it may not be necessary to have a hangar available. For example, an organisation maintaining ELA2 aircraft (when not performing major repairs) may perform the work in alternative suitable faci lities (and possibly at remote locations) as agreed by the competent authority.

2. Protection from the weather elements relates to the normal prevailing local weather elements that are expected throughout any twelve - month period. Aircraft hangar and aircraft component workshop structures should be to a standard that prevents the ingre ss of rain, hail, ice, snow, wind and dust etc. Aircraft hangar and aircraft component workshop floors should be sealed to minimise dust generation.

3. Aircraft maintenance staff should be provided with an area where they may study maintenance instructions and complete continuing airworthiness records in a proper manner.

4. Special case for ELA2 aircraft For ELA2 aircraft, it is acceptable not to have access to a hangar or dedicated workshops.

Depending on the scope of work, other facilities are acceptable as long as protection is ensured from inclement weather and contamination. This may include, for exam ple, working in the field or in non - aviation premises (closed or not).

These facilities do not need to be individually approved by the competent authority as long as the maintenance organisation manual describes for each type of facility the scope of work, the tooling and equipment available, and the permitted environmental c onditions (weather, contamination).

The organisation should include, as part of the periodic internal organisational review, a sampling of the compliance with these conditions during certain maintenance events.

ED Decision 2015/029/R It is acceptable to combine any or all of the office accommodation requirements into one office subject to the staff having sufficient room to carry out assigned tasks.

AMC M.A.605(c) Facilities

ED Decision 2020/002/R 1. Storage facilities for serviceable aircraft components should be clean, well - ventilated and maintained at an even dry temperature to minimise the effects of condensation.

Manufacturer’s storage recommendations should be followed for those aircraft componen ts identified in such published recommendations.

2. Adequate storage racks should be provided and strong enough to hold aircraft components and provide sufficient support for large aircraft components such that the component is not damaged during storage.

3. All aircraft components, wherever practicable, should remain packaged in their protective material to minimise damage and corrosion during storage. A shelf life control system should be utilised and identity tags used to identify components.

4. Segregation means storing unserviceable components in a separate secured location from serviceable components.

5. Segregation and management of any unserviceable component should be ensured according to the pertinent procedure approved to that organisation.

6. Procedures should be defined by the organisation describing the decision process for the status of unserviceable components. This procedure should identify at least the following: − role and responsibilities of the persons managing the decision process; − description of the decision process to choose between maintaining, storing or mutilating a component; − traceability of decision.

7. Once unserviceable components or materials have been identified as unsalvageable in accordance with M.A.501(a)(3) or ML.A.504(c) , the organisation should establish secure areas in which to segregate such items and to prevent unauthorised access. Unsalvageable components should be managed through a procedure to ensure that these components receive the appropriate final disposal acco rding to M.A.504(b) or ML.A.504(d) or (e). The person responsible for the implementation of this procedure should be identified.

Notwithstanding the fact that level 3 personnel may be qualified via EN 4179 to establish and authorise methods, techniques, etc., this does not permit such personnel to deviate from methods and techniques published in the maintenance data, unless the maintenance data expressly permits such deviation.

4. Notwithstanding the general references in EN 4179 to a national aerospace NDT board, all examinations should be conducted by personnel or organisations under the general control of such a board. In the absence of a national aerospace NDT board, examinations should be conducted by personnel or organisations under the general control of the NDT board of a Member State designated by the compete nt authority.

5. Particular non - destructive test means any one or more of the following: dye penetrant, magnetic particle, eddy current, ultrasonic and radiographic methods including X ray and gamma ray.

6. In addition it should be noted that new methods are and will be developed, such as, but not limited to thermography and shearography, which are not specifically addressed by EN 4179.

Until such time as an agreed standard is established such methods shou ld be carried out in accordance with the particular equipment manufacturers’ recommendations including any training and examination process to ensure competence of the personnel with the process.

7. Any approved maintenance organisation that carries out continued airworthiness non - destructive testing should establish qualification procedures for non - destructive testing.

8. Boroscoping and other techniques such as delamination coin tapping are non - destructive inspections rather than non - destructive testing. Notwithstanding such differentiation, approved maintenance organisation should establish a procedure to ensure that p ersonnel who carry out and interpret such inspections are properly trained and assessed for their competence with the process. Non - destructive inspections, not being considered as non - destructive testing by M.A. Subpart F are not listed in Appendix IV to Part - M under class rating D1.

9. The referenced standards, methods, training and procedures should be specified in the maintenance organisation manual.

10. Any such personnel who intend to carry out and/or control a non - destructive test for which they were not qualified prior to the effective date of Part - M should qualify for such non - destructive test in accordance with EN 4179.

In this context officially recognised standard means those standards established or published by an official body whether having legal personality or not, which are widely recognised by the air transport sector as constituting good practice.

ED Decision 2015/029/R 1. Once the applicant for M.A. Subpart F approval has determined the intended scope of approval for consideration by the competent authority, it will be necessary to show that all tools and equipment as specified in the maintenance data can be made available when needed.

2. All such tools should be clearly identified and listed in a control register including any personal tools and equipment that the organisation agrees can be used.

3. For tools required on an occasional basis, the organisation should ensure that they are controlled in terms of servicing or calibration as required.

AMC M.A.608(b) Components, equipment and tools

ED Decision 2015/029/R 1. The control of these tools and equipment requires that the organisation has a procedure to inspect/service and, where appropriate, calibrate such items on a regular basis and indicate to users that the item is within any inspection or service or calibra tion time - limit. A clear system of labelling all tooling, equipment and test equipment is therefore necessary giving information on when the next inspection or service or calibration is due and if the item is unserviceable for any other reason where it may not be obvious. A register should be maintained for all the organisation’s precision tooling and equipment together with a record of calibrations and standards used.

2. Inspection, service or calibration on a regular basis should be in accordance with the equipment manufacturers' instructions except where the M.A. Subpart F organisation can show by results that a different time period is appropriate in a particular case.

AMC M.A.613(a) Component certificate of release to service

ED Decision 2020/002 /R 1. An aircraft component which has been maintained off the aircraft requires the issuance of a CRS for such maintenance and another CRS in regard to being installed properly on the aircraft when such action occurs. When an organisation maintains a component f or use by the same organisation, an EASA Form 1 may not be necessary depending upon the organisation’s internal release procedures defined in the maintenance organisation exposition.

2. In the case of components in storage prior to Part - 145 , Part - M and Part - 21 and not released on an EASA Form 1 or equivalent in accordance with M.A.501(a) or removed serviceable from a serviceable aircraft which have been withdrawn from service, this paragraph provides additional guidance regarding the conditions under which an EASA Form 1 may be issued.

2.1. An EASA Form 1 may be issued for an aircraft component which has been: − Maintained before Part - 145 , or Part - M became effective or manufactured before Part - 21 became effective.

− Used on an aircraft and removed in a serviceable condition. Examples include leased and loaned aircraft components.

− Removed from aircraft which have been withdrawn from service, or from aircraft which have been involved in abnormal occurrences such as accidents, incidents, heavy landings or lightning strikes.

− Components maintained by an unapproved organisation.

2.2. An appropriately rated M.A. Subpart F maintenance organisation may issue an EASA Form 1 as detailed in this AMC subparagraph 2.5 to 2.9, as appropriate, in accordance with the procedures detailed in the manual as approved by the competent authority. The appropriately rated M.A. Subpart F maintenance organisation is responsible for ensuring that all reasonable measures have been taken to ensure that only approved and serviceable aircraft components are issued an EASA Form 1 under this paragraph.

2.3. For the purposes of this paragraph 2 only, ‘appropriately rated’ means an organisation with an approval class rating for the type of component or for the product in which it may be installed.

2.4. An EASA Form 1 issued in accordance with this paragraph 2 should be issued by signing in block 14b and stating ‘Inspected/Tested’ in block 11. In addition, block 12 should specify: 2.4.1. when the last maintenance was carried out and by whom; 2.4.2. if the component is unused, when the component was manufactured and by whom with a cross - reference to any original documentation which should be included with the Form; 2.4.3. a list of all ADs, repairs and modifications known to have been incorporated. If no ADs or repairs or modifications are known to be incorporated then this should be so stated; 2.4.4. detail of life used for life - limited parts and time - controlled components being any combination of fatigue, overhaul or storage life; 2.4.5. for any aircraft component having its own maintenance history record, reference to the particular maintenance history record as long as the record contains the Powered by EASA eRules Page 118 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS details that would otherwise be required in block 12. The maintenance history record and acceptance test report or statement, if applicable, should be attached to the EASA Form 1.

2.5. New/unused aircraft components 2.5.1. Any unused aircraft component in storage without an EASA Form 1 up to the effective date(s) for Part - 21 that was manufactured by an organisation acceptable to the competent authority at the time may be issued an EASA Form 1 by an appropriately rated mainte nance organisation approved under M.A. Subpart F . The EASA Form 1 should be issued in accordance with the following subparagraphs which should be included in a procedure within the maintenance organisation manual.

Note 1: It should be understood that the release of a stored but unused aircraft component in accordance with this paragraph represents a maintenance release under M.A. Subpart F and not a production release under Part - 21. It is not intended to bypass the production release procedure agreed by the Member State for parts and subassemblies intended for fitment on the manufacturers own production line.

(a) An acceptance test report or statement should be available for all used and unused aircraft components that are subject to acceptance testing after manufacturing or maintenance as appropriate.

(b) The aircraft component should be inspected for compliance with the manufacturer’s instructions and limitations for storage and condition including any requirement for limited storage life, inhibitors, controlled climate and special storage containers. In a ddition, or in the absence of specific storage instructions, the aircraft component should be inspected for damage, corrosion and leakage to ensure good condition.

2.5.2. If it is not possible to establish satisfactory compliance with all applicable conditions specified in subparagraph 2.5.1 (a) to (c) inclusive, the aircraft component should be disassembled by an appropriately rated organisation and subjected to a check for incorporated ADs, repairs and modifications and inspected/tested in accordance with the maintenance d ata to establish satisfactory condition and, if relevant, all seals, lubricants and life - limited parts replaced. Upon satisfactory completion after reassembly, an EASA Form 1 may be issued stating what was carried out and the reference to the maintenance d ata included.

2.6. Used aircraft components removed from a serviceable aircraft.

2.6.1. Serviceable aircraft components removed from a Member State registered aircraft may be issued an EASA Form 1 by an appropriately rated organisation subject to compliance with this subparagraph.

(a) The organisation should ensure that the component was removed from the aircraft by an appropriately qualified person.

(b) The aircraft component may only be deemed serviceable if the last flight operation with the component fitted revealed no faults on that component or related system.

Powered by EASA eRules Page 119 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS (c) The aircraft component should be inspected for satisfactory condition including in particular damage, corrosion or leakage and compliance with any additional maintenance data.

(d) The aircraft record should be researched for any unusual events that could affect the serviceability of the aircraft component such as involvement in accidents, incidents, heavy landings or lightning strikes. Under no circumstances may an EASA Form 1 be issued in accordance with this paragraph 2.6 if it is suspected that the aircraft component has been subjected to extremes of stress, temperatures or immersion which could affect its operation.

(e) A maintenance history record should be available for all used serialised aircraft components.

(f) Compliance with known modifications and repairs should be established.

(g) The flight hours/cycles /landings as applicable of any life - limited parts and time - controlled components including time since overhaul should be established.

(h) Compliance with known applicable airworthiness directives should be established.

(i) Subject to satisfactory compliance with this subparagraph 2.6.1, an EASA Form 1 may be issued and should contain the information as specified in paragraph 2.4 including the aircraft from which the aircraft component was removed.

2.6.2. Serviceable aircraft components removed from a non - Member State registered aircraft may only be issued an EASA Form 1 if the components are leased or loaned from the maintenance organisation approved under M.A. Subpart F who retains control of the airworthiness status of the components. An EASA Form 1 may be issued and should contain the information as specified in paragraph 2.4 including the aircraft from which the aircraft component was removed.

2.7. Used aircraft components removed from an aircraft withdrawn from service. Serviceable aircraft components removed from a Member State registered aircraft withdrawn from service may be issued an EASA Form 1 by a maintenance organisation approved under M.A. Subpart F subject to compliance with this subparagraph.

(a) Aircraft withdrawn from service are sometimes dismantled for spares. This is considered to be a maintenance activity and should be accomplished under the control of an organisation approved under M.A. Subpart F , employing procedures approved by the competent authority.

(b) To be eligible for installation, components removed from such aircraft may be issued with an EASA Form 1 by an appropriately rated organisation following a satisfactory assessment.

(c) As a minimum, the assessment will need to satisfy the standards set out in paragraphs 2.5 and 2.6 as appropriate. This should, where known, include the possible need for the alignment of scheduled maintenance that may be necessary to comply with the mainte nance programme applicable to the aircraft on which the component is to be installed.

Powered by EASA eRules Page 120 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS (d) Irrespective of whether the aircraft holds a certificate of airworthiness or not, the organisation responsible for certifying any removed component should satisfy itself that the manner in which the components were removed and stored are compatible with th e st andards required by M.A. Subpart F .

(e) A structured plan should be formulated to control the aircraft disassembly process.

The disassembly is to be carried out by an appropriately rated organisation under the supervision of certifying staff, who will ensure that the aircraft components are remo ved and documented in a structured manner in accordance with the appropriate maintenance data and disassembly plan.

(f) All recorded aircraft defects should be reviewed and the possible effects these may have on both normal and standby functions of removed components are to be considered.

(g) Dedicated control documentation is to be used as detailed by the disassembly plan, to facilitate the recording of all maintenance actions and component removals performed during the disassembly process. Components found to be unserviceable are to be identi fied as such and quarantined pending a decision on the actions to be taken. Records of the maintenance accomplished to establish serviceability are to form part of the component maintenance history.

(h) Suitable M.A. Subpart F facilities for the removal and storage of removed components are to be used which include suitable environmental conditions, lighting, access equipment, aircraft tooling and storage facilities for the work to be undertaken. While it may be acceptable for components to be removed, given local environmental conditions, without the benefit of an enclosed facility subsequent disassembly (if required) and storage of the components should be in accordance with the manufacturer’s recommendations.

2.8. Used aircraft components maintained by organisations not approved in accordance with M.A Subpart F , Part - 145 or Part - CAO.

For used components maintained by a maintenance organisation not approved under Part - M Subpart F or Part - 145 , due care should be taken before acceptance of such components. In such cases an appropriately rated maintenance organisation approved under M.A. Subpart F should establish satisfactory conditions by: (a) dismantling the component for sufficient inspection in accordance with the appropriate maintenance data, (b) replacing of all life - limited parts and time - controlled components when no satisfactory evidence of life used is available and/or the components are in an unsatisfactory condition, (c) reassembling and testing as necessary the component, (d) completing all certification requirements as specified in M.A.613 .

In the case of used components maintained by an FAA Part - 145 repair station (USA) or by TCCA CAR573 approved maintenance organisations (Canada) that does not hold an EASA Part - 145 or M.A. Subpart F approval, the conditions (a) through (d) described above may be replaced by the following conditions: (a) availability of an 8130 - 3 (FAA) or TCCA 24 - 0078 (TCCA) or an Authorized Relea se Certificate Form One (TCCA), Powered by EASA eRules Page 121 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS (b) verification of compliance with all applicable airworthiness directives, (c) verification that the component does not contain repairs or modifications that have not been approved in accordance with Part - 21, (d) inspection for satisfactory condition including in particular damage, corrosion or leakage, (e) issuance of an EASA Form 1 in compliance with paragraphs 2.2, 2.3 and 2.4.

2.9. Used aircraft components removed from an aircraft involved in an accident or incident.

Such components should only be issued with an EASA Form 1 when processed in accordance with paragraph 2.7 and a specific work order including all additional necessary tests and inspections made necessary by the accident or incident. Such a work order may require input from the TC holder or original manufacturer as appropriate. This work order should be referenced in block 12.

3. A certificate should not be issued for any component when it is known that the component is unserviceable except in the case of a component undergoing a series of maintenance processes at several approved maintenance organisations and the component needs a certificate for the previous maintenance process carried out for the next approved maintenance organisation to accept the component for subsequent maintenance processes. In such a case, a clear statement of limitation should be endorsed in block.

4. The certificate is to be used for export/import purposes, as well as for domestic purposes, and serves as an official certificate for components from the manufacturer/maintenance organisation to users. It should only be issued by organisations approved by a competent authority or the Agency as applicable within the scope of the approval.

M.A.614 Maintenance and airworthiness review records

Regulation (EU) 20 20 / 270 (a) The approved maintenance organisation shall record all details of work carried out. Records necessary to prove all requirements have been met for the issue of the certificate of release to service including the subcontractor's release documents and for the issue of any airworthiness review certificate shall be retained.

ED Decision 2020/002/R M.A.615(b) refers to work carried out by another organisation which is not appropriately approved under M.A. Subpart F , Part - 145 or Part - CAO to carry out such tasks.

The intent is to permit the acceptance of specialised maintenance services, such as, but not limited to, non - destructive testing, surface treatment, heat - treatment, welding, fabrication of specified parts for minor repairs and modifications, etc., without the need of Subpart F approval for those tasks.

The requirement that the organisation performing the specialised services must be ‘appropriately qualified’ means that it should meet an officially recognised standard or, otherwise, it should be acceptable to the competent authority (through the approval of the Maintenance Organisation Manual).

‘Under the control of the Subpart F organisation’ means that the Subpart F organisation should investigate the capability of the subcontracted organisation (including qualifications, facilities, equipment and materials) and ensure that such organisation: Powered by EASA eRules Page 124 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS − Receives appropriate maintenance instructions and maintenance data for the task to be performed.

− Properly records the maintenance performed in the Subpart F airworthiness records.

− Notifies the Subpart F organisation for any deviation or non - conformity, which has arisen during such maintenance.

The CRS may be issued either at the subcontractors or at the organisation facility by authorised certifying staff, and always under the M.A. Subpart F organisation reference. Such staff would normally come from the M.A. Subpart F organisation but may otherwise be a person from the subcontractor who meets the M.A. Subpart F organisation certifying staff standard which itself is approved by the competent authority via the Maintenance Organisation Manual.

Subcontracted specialised services organisations should be listed in the Maintenance Organisation Manual of the Subpart F organisation together with their qualifications, and the associated control procedures.

M.A.616 Organisational review

Regulation (EU) No 1321/2014 To ensure that the approved maintenance organisation continues to meet the requirements of this Subpart, it shall organise, on a regular basis, organisational reviews.

AMC M.A.616 Organisational review

ED Decision 2015/029/R 1. The primary objectives of the organisational review are to enable the approved maintenance organisation to ensure that it can deliver a safe product and that approved maintenance organisation remains in compliance with the requirements.

2. The approved maintenance organisation should identify: 2.1. the person responsible for the organisational review; 2.2. the frequency of the reviews; 2.3. the scope and content of the reviews; 2.4. the persons accomplishing the reviews; 2.5. the procedure for planning, performing and processing review findings; and, 2.6. the procedure for ensuring corrective actions are carried out in the appropriate time frame.

3. The organisation quality system as specified in Part - 145 provides an acceptable basic structure for the organisational review system for organisations with more than 10 maintenance staff, dependent upon the complexity of the organisation.

4. Appendix VIII to AMC M.A.616 should be used to manage the organisational reviews.

Part 0 ‘General organisation’ of the continuing airworthiness management exposition should include a corporate commitment by the CAMO, signed by the accountable manager, confirming that the continuing airworthiness management exposition and any associat ed manuals define the organisation’s compliance with Part - M and, as applicable, with Part - ML and will be complied with at all times.

2. The accountable manager’s exposition statement should embrace the intent of the following paragraph, and in fact this statement may be used without amendment. Any amendment to the statement should not alter its intent: ‘This exposition defines the organisation and procedures upon which the competent authority’s* CAMO approval is based.

These procedures are approved by the undersigned and should be complied with, as applicable, in order to ensure that all continuing airworthiness tasks are carried out on time to an approved standard.

It is accepted that these procedures do not override the necessity of complying with any new or amended regulation published from time to time where these new or amended regulations are in conflict with these procedures.

It is understood that the competent authority* will approve this organisation whilst the competent authority* is satisfied that the procedures are followed and the work standard is maintained. It is understood that the competent authority* reserves the rig ht to suspend, limit or revoke the CAMO approval or the air operator certificate, as applicable, if the competent authority* has evidence that the procedures are not followed and standards not upheld.

AMC M.A.706 Personnel requirements

ED Decision 2015/029/R 1. The person or group of persons should represent the continuing airworthiness management structure of the organisation and be responsible for all continuing airworthiness functions.

Dependent on the size of the operation and the organisational set - up, the c ontinuing airworthiness functions may be divided under individual managers or combined in nearly any number of ways. However, if a quality system is in place it should be independent from the other functions.

2. The actual number of persons to be employed and their necessary qualifications is dependent upon the tasks to be performed and thus dependent on the size and complexity of the organisation (general aviation aircraft, corporate aircraft, number of aircraft and the aircraft type s, complexity of the aircraft and their age and for commercial air transport, route network, line or charter, ETOPS) and the amount and complexity of maintenance contracting.

Consequently, the number of persons needed, and their qualifications may differ g reatly from one organisation to another and a simple formula covering the whole range of possibilities is not feasible.

3. To enable the competent authority to accept the number of persons and their qualifications, an organisation should make an analysis of the tasks to be performed, the way in which it intends to divide and/or combine these tasks, indicate how it intends to assign responsibilities and establish the number of man/hours and the qualifications needed to perform the tasks.

4. Nominated person or group of persons should have: 4.1. practical experience and expertise in the application of aviation safety standards and safe operating practices; 4.2. a comprehensive knowledge of: (a) relevant parts of operational requirements and procedures; (b) the AOC holder's operations specifications when applicable; (c) the need for, and content of, the relevant parts of the AOC holder's operations manual when applicable; 4.3. knowledge of quality systems; 4.4. five years relevant work experience of which at least two years should be from the aeronautical industry in an appropriate position; 4.5. a relevant engineering degree or an aircraft maintenance technician qualification with additional education acceptable to the competent authority. ‘relevant engineering degree’ means an engineering degree from aeronautical, mechanical, electrical, electron ic, avionic or other studies relevant to the maintenance and continuing airworthiness of aircraft/aircraft components; The above recommendation may be replaced by 5 years of experience additional to those already recommended by paragraph 4.4 above. These 5 years should cover an appropriate combination of experience in tasks related to aircraft maintenance and/or continuing airworthiness management and/or surveillance of such tasks; 4.6. thorough knowledge with the organisation's continuing airworthiness management exposition; 4.7. knowledge of a relevant sample of the type(s) of aircraft gained through a formalised training course. These courses should be at least at a level equivalent to Part - 66 Appendix III Level 1 General Familiarisation and could be imparted by a Part - 147 organisation, by the manufacturer, or by any other organisation accepted by the competent authority.

‘Relevant sample’ means that these courses should cover typical systems embodied in those aircraft being within the scope of approval.

For all balloons and any other aircraft of 2 730 kg MTOM and below the formalised training courses may be replaced by demonstration of knowledge. This knowledge may be demonstrated by documented evidence or by an assessment performed by the competent autho rity. This assessment should be recorded.

4.8. knowledge of maintenance methods.

4.9. knowledge of applicable regulations.

Regulation (EU) No 1321/2014 (e) The organisation shall maintain a record of all airworthiness review staff, which shall include details of any appropriate qualification held together with a summary of relevant continuing airworthiness management experience and training and a copy of the authorisation. This record shall be retained until two years after the airworthiness review staff have left the organisation.

AMC M.A.707(a) Airworthiness review staff

ED Decision 2020/002/R 1. Airworthiness review staff are only required if the CAMO wants to be granted M.A.711(b) airworthiness review and, if applicable, M.A.711(c) permit to fly privileges.

2. ‘experience in continuing airworthiness’ means any appropriate combination of experience in tasks related to aircraft maintenance and/or continuing airworthiness management and/or surveillance of such tasks.

3. A person qualified to the AMC M.A.706 subparagraph 4.5 should be considered as holding the equivalent to an aeronautical degree.

4. An appropriate licence in compliance with Annex III (Part - 66) is any one of the following: − a category B1 licence in the subcategory of the aircraft reviewed, or − a category B2 or C licence, or − in the case of piston - engine non - pressurised aeroplanes of 2 000 kg MTOM and below, a category B3 licence, − in the case of sailplanes, powered sailplanes, ELA1 aeroplanes, balloons and airships, a category L licence in the appropriate subcategory.

It is not necessary to satisfy the experience requirements of Annex III ( Part - 66 ) at the time of the review.

5. To hold a position with appropriate responsibilities means the airworthiness review staff should have a position in the organisation independent from the airworthiness management process or with overall authority on the airworthiness management process of complete aircraft.

Independence from the airworthiness management process may be achieved, among other ways, by: − Being authorised to perform airworthiness reviews only on aircraft for which the person has not participated in their management. For example, performing airworthiness reviews on a specific model line, while being involved in the airworthiness management o f a different model line.

− M.A. Subpart G organisations with Part - 145 / M.A. Subpart F /Part - CAO approval, may nominate maintenance personnel from their Part - 145 /M.A. Subpart F /Part - CAO organisation as airworthiness review staff, as long as they are not involved in the airworthiness management of the aircraft. These personnel should not have been involved in the release to service of that particular aircraft (other than maintenance tasks Powered by EASA eRules Page 137 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS performed during the physical survey of the aircraft or performed as a result of findings discovered during such physical survey) to avoid possible conflict of interests.

− Nominating as airworthiness review staff personnel from the quality department of the CAMO.

Overall authority on the airworthiness management process of complete aircraft may be achieved, among other ways, by: − Nominating as airworthiness review staff the accountable manager or the nominated postholder.

− Being authorised to perform airworthiness reviews only on those particular aircraft for which the person is responsible for the complete continuing airworthiness management process.

− In the case of one - man organisations, this person has always overall authority. This means that this person can be nominated as airworthiness review staff.

AMC1 M.A.708(c) Continuing airworthiness management

ED Decision 2020/002/R 1. In case of complex motor - powered aircraft, aircraft used for CAT operations, aircraft used for commercial specialised operations and aircraft used by commercial ATO, the provisions of M.A.201 establish that a CAMO is required. This CAMO is in charge of the continuing airworthiness management and this includes the tasks specified in M.A.301 points (2), (3), (5) and (6). If the CAMO does not hold the appropriate maintenance organisation approval, then the CAMO should conclude a contract with the appropriate organisation(s).

2. The CAMO bears the responsibility for the airworthy condition of the aircraft for which it performs the continuing airworthiness management. Thus, it should be satisfied before the intended flight that all required maintenance has been properly carried out.

3. The CAMO should agree with the operator on the process to select a maintenance organisation before concluding any contract with a maintenance organisation.

4. The fact that the CAMO has contracted a maintenance organisation approved under Subpart F or Part - 145 should not prevent it from checking at the maintenance facilities on any aspect of the contracted work to fulfil its responsibility for the airworthiness of the aircraft.

5. The contract between the CAMO and the maintenance organisation(s) should specify in detail the responsibilities and the work to be performed by each party.

6. Both the specification of work and the assignment of responsibilities should be clear, unambiguous and sufficiently detailed to ensure that no misunderstanding arises between the parties concerned that could result in a situation where work that has an effect on the airworthiness or serviceability of aircraft is not or will not be properly performed.

7. Special attention should be paid to procedures and responsibilities to ensure that all maintenance work is performed, service bulletins are analysed and decisions are taken on their accomplishment, airworthiness directives are accomplished on time and t hat all work, including non - mandatory modifications, is carried out to approved data and to the latest standards.

8. Appendix XI to this AMC gives further details on the subject.

AMC2 M.A.708(c) Continuing airworthiness management

ED Decision 2016/011/R MAINTENANCE CONTRACT WITH ANOTHER CAMO/OPERATOR 1. The purpose of M.A.708(c) is to ensure that all maintenance is carried out by an appropriately approved maintenance organisation. It is possible to contract another operator/CAMO (secondary operator/CAMO) that does not hold a maintenance organisation approval when it proves that s uch a contract is in the interest of the CAMO by simplifying the management of its maintenance, and the CAMO keeps an appropriate control of it. In this case the continuing airworthiness management exposition should include appropriate procedures to ensure that all maintenance is ultimately carried out on time by approved maintenance organisations in accordance with the CAMO’s data. In particular, the quality system procedures should place great emphasis on monitoring compliance with the above. The list of approved maintenance organisations, or a reference to this list, should be included in the CAMO’s continuing airworthiness management exposition.

Powered by EASA eRules Page 142 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS 2. This contract should not preclude the CAMO from ensuring that all maintenance is performed by appropriately approved organisations which comply with the M.A.201 continuing airworthiness responsibility requirements. Typical examples of such arrangements are the following: − Component maintenance: The CAMO may find it more appropriate to have a primary contractor (the secondary operator/CAMO) dispatching the components to appropriately approved organisations rather than sending themselves different types of components to various maintenance organisa tions approved under Part - 145 . The benefit for the CAMO is that the management of maintenance is simplified by having a single point of contact for component maintenance. The CAMO remains responsible for ensuring that all maintenance is performed by maintenance organisations approved under Part - 145 and in accordance with the approved standards.

− Aircraft, engine and component maintenance: The CAMO may wish to have a maintenance contract with a secondary operator/CAMO not approved under Part - 145 for the same type of aircraft. A typical case is that of a dry - leased aeroplane between operators where the parties, for consistency or continuity r easons (especially for short - term lease agreements), find it appropriate to keep the aeroplane under the current maintenance arrangement. Where this arrangement involves various Part - 145 approved contractors, it might be more manageable for the lessee CAMO to have a single maintenance contract with the lessor operator/CAMO.

Whatever type of acceptable maintenance contract is concluded, the CAMO is required to exercise the same level of control on contracted maintenance, particularly through the M.A.706(c) continuing airworthiness management group of persons and quality system as referred to in M.A.712 .

GM M.A.708(c) Continuing airworthiness management

ED Decision 2016/011/R For line maintenance, the actual layout of the IATA Standard Ground Handling Agreement may be used as a basis, but this does not preclude the CAMO from ensuring that the content of the contract is acceptable and especially that the contract allows the CAMO to properly exercise its maintenance responsibility. Those parts of the contract that have no effect on the technical or operational aspects of airworthiness are outside the scope of this paragraph.

AMC M.A.708(d) Continuing airworthiness management

ED Decision 2016/011/R The intent of this paragraph is that maintenance contracts are not necessary when the continuing airworthiness management exposition specifies that the relevant maintenance activity may be ordered through one - time work orders. This includes unscheduled line maintenance and may also include component maintenance up to engines, as long as the maintenance is manageable through work orders, both in terms of volume and complexity. It should be noted that this paragraph implies that even where base maintenance is ordered on a case - by - case basis, there should be a written maintenance contract.

M.A.709 Documentation

Regulation (EU) 2020/270 (a) The approved continuing airworthiness management organisation shall hold and use applicable current maintenance data in accordance with point M.A.401 of this Annex (Part - M) or point ML.A.401 of Annex Vb (Part - ML), as applicable, for the performance of continuing airworthiness tasks referred to in point M.A.708 of this Annex (Part - M). That data may be provided by the owner or the operator, subject to an appropriate contract being established with such an owner or operator. In such case, the continuing airworthiness management organisation only needs to keep such data for the duration of the contract, except when required by point M.A.714 of this Annex (Part - M).

(b) For aircraft not used by licenced air carriers in accordance with Regulation (EC) No 1008/2008, the approved continuing airworthiness management organisation may develop ‘baseline’ or ‘generic’ maintenance programmes, or both, in order to allow for the ini tial approval or the extension of the scope of an approval, without having the co ntracts referred to in Appendix I to this Annex (Part - M) or Appendix I to Annex Vb (Part - ML), as applicable. Those ‘baseline’ and ‘generic’ maintenance programmes however do not preclude the need to establish an adequate Aircraft Maintenance Programme in compliance with point M.A.302 of this Annex (Part - M) or ML.A.302 of Annex Vb (Part - ML), as applicable, in due time before exercising the privileges referred to in point M.A.711 of this Annex (Part - M).

AMC M.A.709 Documentation

ED Decision 2016/011/R When using maintenance data provided by the customer, the CAMO is responsible for ensuring that this data is current. As a consequence, it should establish appropriate procedures or provisions in the contract with the customer.

The sentence ‘…, except when required by point M.A.714 ’, means, in particular, the need to keep a copy of the customer data which was used to perform continuing airworthiness activities during the contract period.

‘Baseline’ maintenance programme: it is a maintenance programme developed for a particular aircraft type following, where applicable, the maintenance review board (MRB) report, the type certificate holder’s maintenance planning document (MPD), the relevant chapters of the maintenance manual or any other maintenance data containing information on scheduling.

‘Generic’ maintenance programme: it is a maintenance programme developed to cover a group of similar types of aircraft. These programmes should be based on the same type of instructions as the baseline maintenance programme. Examples of ‘generic’ maintenan ce programmes could be Cessna 100 Series (covering Cessna 150, 172, 177, etc.).

‘Baseline’ and ‘generic’ maintenance programmes are not applicable to a particular aircraft registration mark, but to an aircraft type or group of types, and should be available to the competent authority prior to the initial approval and prior to the exte nsion of the scope of an existing organisation approval. The intent is that the competent authority is aware of the scope and complexity of tasks that will be managed before granting an organisation approval or change of approval.

After this initial approval, when an owner/operator is contracted, the baseline or generic maintenance programme, as applicable, may be used to establish the M.A.302 aircraft maintenance programme, incorporating the additional maintenance tasks and indicating those which are not applicable to a particular aircraft registration mark. This may be achieved by adding an Annex to the baseline/generic Powered by EASA eRules Page 144 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS maintenance programme for each aircraft registration, specifying which tasks are added and which are not applicable. This will result in an aircraft maintenance programme specific for each customer.

However, this does not mean that this adaptation must be performed for each contracted aircraft registration. The reason is that the customer may already have an approved aircraft maintenance programme, which in that case should be used by the continuing a irworthiness management organisation to manage the continuing airworthiness of such aircraft.

Continuing airworthiness management organisations may seek authorisation for indirect approval in order to amend the aircraft maintenance programme mentioned above in accordance with M.A.302(c) . The indirect approval procedure should include provisions to notify to the competent authority that an aircraft maintenance programme specific for a customer has been created. The reason is that, according to M.A.704(a)9 , for aircraft not used by air carriers licensed in accordance with Regulation (EC) No 1008/2008, the Continuing Airworthiness Management Exposition (CAME) only needs to include the reference to the baseline/generic maintenance programme.

GM M.A.709 Documentation

ED Decision 2015/029/R Paragraph M.A.709(a) refers to continuing airworthiness tasks referred to in M.A.708 . As a consequence, this covers continuing airworthiness management tasks but not airworthiness reviews.

Regulation (EU) 2020/270 When the organisation approved in accordance with point M.A.711(b) of this Annex (Part - M) performs airworthiness reviews, they shall be performed in accordance with point M.A.901 of this Annex (Part - M) or point ML.A.903 of Annex Vb (Part - ML), as applicable .

GM M.A.710 Airworthiness review

ED Decision 2020/002/R Responsibilities of airworthiness review staff: The following is a summary of the requirements contained in M.A.710 as well as the associated AMCs and Appendices, in relation to the responsibilities of the airworthiness review staff: − Airworthiness review staff are responsible for performing both the docu mental and the physical survey.

− Procedures must be established by the CAMO in order to perform the airworthiness review, including the depth of samplings (refer to Appendix V to AMC 1 M.A.704 , paragraphs 4.2 and 4.3).

− Procedures must make very clear that the final word about the depth of the inspections (both documental and physical) belongs to the airworthiness review staff, who can go beyond the depth contained in the CAME if they find it necessary. At the end, it is the responsibility of the airworthiness review staff to be satisfied that the aircraft complies with Part - M or Part - ML, as applicable, and is airworthy, and the organisation must ensure that no pressure or restrictions are imposed on the airworthiness review st aff when performing their duty.

Powered by EASA eRules Page 145 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS − A compliance report must be produced by the airworthiness review staff, detailing all items checked and the outcome of the review.

− Airworthiness review staff are responsible for the items checked during the airworthiness review. However, they do not take over the responsibilities of the CAMO, Part - 145 , DOA, POA or any other organisations, not being responsible for problems not detected during the airworthiness review or for the possibility that the approved or declared maintenance programme may not include certain recommendations from the Design Approv al Holder.

Obviously, if the airworthiness review staff are not independent of the airworthiness management process and were nominated on the basis of the option of having overall authority on such a process, they will be responsible for the full continuin g airworthiness of such aircraft.

Nevertheless, this responsibility will be a consequence of their position related to M.A.706 and not of their position as airworthiness review staff ( M.A.707 ).

− The issuance of the airworthiness review certificate (ARC) by the airworthiness review staff only certifies that the aircraft is considered airworthy in relation to the scope of the airworthiness review performed and the fact that the airworthiness review staff are not aware of instances of non - compliance which endanger flight safety. Furthermore, it only certifies that the aircraft is considered airworthy at the time of the review.

It is the responsibility of the owner or contracted CAMO to ensure that the aircraft is fully airworthy at any time.

AMC M.A.711(a)(3) Privileges of the organisation

ED Decision 2016/011/R SUBCONTRACTING OF CONTINUING AIRWORTHINESS TASKS 1. The CAMO may subcontract certain continuing airworthiness management tasks to qualified persons or organisations. The subcontracted person or organisation performs the continuing airworthiness management tasks as an integral part of the CAMO’s continuing a irworthiness management system, irrespective of any other approval held by the subcontracted person or organisation (including CAMO or Part - 145 approval).

2. The CAMO remains accountable for the satisfactory completion of the continuing airworthiness management tasks irrespective of any contract that may be established.

3. In order to fulfil this responsibility, the CAMO should be satisfied that the actions taken by the subcontracted person or organisation meet the standards required by Subpart G . Therefore, the CAMO management of such activities should be accomplished: (a) by active control through direct involvement, and/or (b) by endorsing the recommendations made by the subcontracted person or organisation.

4. In order to retain ultimate responsibility, the CAMO should limit subcontracted tasks to the activities specified below: (a) airworthiness directive analysis and planning; (b) service bulletin analysis; (c) planning of maintenance; (d) reliability monitoring, engine health monitoring; (e) maintenance programme development and amendments; (f) any other activities, which do not limit the CAMO responsibilities, as agreed by the competent authority.

5. The CAMO’s controls associated with subcontracted continuing airworthiness management tasks should be reflected in the associated contract and be in accordance with the CAMO policy and procedures defined in the continuing airworthiness management expositio n. When such tasks are subcontracted, the continuing airworthiness management system is considered to be extended to the subcontracted persons or organisations.

6. With the exception of engines and auxiliary power units, contracts would normally be limited to one organisation per aircraft type for any combination of the activities described in Appendix II. Where contracts are made with more than one organisation, the CAMO should demonstrate Powered by EASA eRules Page 147 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS that adequate coordination controls are in place and that the individuals’ responsibilities are clearly defined in the related contracts.

7. Contracts should not authorise the subcontracted organisation to subcontract to other organisations elements of the continuing airworthiness management tasks.

8. The competent authority should exercise oversight of the subcontracted activities through the CAMO approval. The contracts should be acceptable to the competent authority. The CAMO should only subcontract to organisations which are specified by the compete nt authority on EASA Form 14 .

9. The subcontracted organisation should agree to notify the CAMO of any changes affecting the contract as soon as practical. The CAMO should then inform its competent authority. Failure to do so may invalidate the competent authority’s acceptance of the cont ract.

10. Appendix II to AMC M.A.711(a)(3) provides information on the subcontracting of continuing airworthiness management tasks.

AMC M.A.711(b) Privileges of the organisation

ED Decision 2015/029/R An organisation may be approved for the privileges of M.A.711(a) only, without the privilege to carry out airworthiness reviews. This can be contracted to another appropriately approved organisation. In such a case, it is not mandatory that the contracted organisation is linked to an AOC holder, being possible to contr act an appropriately approved independent continuing airworthiness management organisation which is approved for the same aircraft type.

In order to be approved for the privileges of M.A.711(b) for a particular aircraft type, it is necessary to be approved for the privileges of M.A.711(a) for that aircraft type. As a consequence, the normal situation in this case is that the organisation will be performing continuing airworthiness management tasks and performing airworthiness reviews on every aircraft type contained in the approval certifi cate.

Nevertheless, this does not necessarily mean that the organisation needs to be currently managing an aircraft type in order to be able to perform airworthiness reviews on that aircraft type. The organisation may be performing only airworthiness reviews on an aircraft type without having any customer under contract for that type.

Furthermore, this situation should not necessarily lead to the removal of the aircraft type from the organisation approval. As a matter of fact, since in most cases the airworthiness review staff are not involved in continuing airworthiness management acti vities, it cannot be argued that these airworthiness review staff are going to lose their skills just because the organisation is not managing a particular aircraft type. The important issue in relation to maintaining a particular aircraft type in the orga nisation approval is whether the organisation continuously fulfils all the Subpart G requirements (facilities, documentation, qualified personnel, quality system, etc.) required for initial approval.

AMC M.A.711(c) Privileges of the organisation

ED Decision 2020/002/R The sentence ‘for the particular aircraft for which the organisation is approved to issue the airworthiness review certificate’ contained in M.A.711(c) means that: − For aircraft used by air carriers licensed in accordance with Regulation (EC) No 1008/2008 , and for aircraft above 2 730kg MTOM, the permit to fly can only be issued for aircraft which are in a controlled environment and are managed by that CAMO.

Regulation (EU) 2015/1536 (a) To ensure that the approved continuing airworthiness management organisation continues to meet the requirements of this Subpart, it shall establish a quality system and designate a quality manager to monitor compliance with, and the adequacy of, procedures required to ensure airworthy aircraft. Compliance monitoring shall include a feedback system to the accountable manager to ensure corrective action as necessary.

(b) The quality system shall monitor activities carried out under Section A, Subpart G of this Annex (Part - M) . It shall at least include the following functions: 1. monitoring that all activities carried out under Section A, Subpart G of this Annex (Part - M) are being performed in accordance with the approved procedures, and; 2. monitoring that all contracted maintenance is carried out in accordance with the contract, and; 3. monitoring the continued compliance with the requirements of this Part.

(d) Where the approved continuing airworthiness management organisation is approved in accordance with another Part, the quality system may be combined with that required by the other Part.

(e) For licenced air carriers in accordance with Regulation (EC) No 1008/2008 the M.A. Subpart G quality system shall be an integrated part of the operator's quality system.

(f) In the case of a small organisation not managing the continuing airworthiness of aircraft used by licenced air carriers in accordance with Regulation (EC) No 1008/2008, the quality system may be replaced by regular organisational reviews subject to the app roval of the competent authority, except when the organisation issues airworthiness review certificates for aircraft above 2730 kg MTOM other than balloons. In the case where there is no quality system, the organisation shall not contract continuing ai rworthiness management tasks to other parties.

AMC M.A.712(a) Quality system

ED Decision 2015/029/R 1. Procedures should be held current such that they reflect best practice within the organisation.

It is the responsibility of all employees to report any difficulties with the procedures via their organisation’s internal occurrence reporting mechanisms.

2. All procedures, and changes to the procedures, should be verified and validated before use where practicable.

3. The feedback part of the system should address who is required to rectify any non - compliance in each particular case and the procedure to be followed if rectification is not completed within appropriate timescales. The procedure should lead to the accounta ble manager specified in M.A.706 .

4. The independent quality audit reports referenced in AMC M.A.712(b) should be sent to the relevant department for rectification action giving target rectification dates. Rectification dates Powered by EASA eRules Page 149 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS should be discussed with such department before the quality department or nominated quality auditor confirms such dates in the report. The relevant department is required to rectify findings and inform the quality manager or the quality auditor of such rec tification.

5. The accountable manager should hold regular meetings with staff to check progress on rectification except that in the large organisations such meetings may be delegated on a day to day basis to the quality manager subject to the accountable manager meeting at least twice per year with the senior staff involved to review the overall performance and receiving at least a half yearly summary report on findings of non - compliance.

AMC M.A.712(b) Quality System

ED Decision 2020/002/R 1. The primary objectives of the quality system are to enable the CAMO to ensure airworthy aircraft and to remain in compliance with the Part - M and, as applicable, Part - ML requirements.

2. An essential element of the quality system is the independent audit.

3. The independent audit is an objective process of routine sample checks of all aspects of the CAMO ability to carry out continuing airworthiness management to the required standards. It includes some product sampling as this is the end result of the process .

4. The independent audit represents an objective overview of the complete continuing airworthiness management related activities. It is intended to complement the M.A.902 or ML.A.902 requirement for an airworthiness review to be satisfied that all aircraft managed by the organisation remain airworthy.

5. The independent audit should ensure that all aspects of M.A. Subpart G compliance are checked annually, including all the sub - contracted activities, and may be carried out as a complete single exercise or subdivided over the annual period in accordance with a scheduled plan. The independent audit does not require each proced ure to be checked against each product line when it can be shown that the particular procedure is common to more than one product line and the procedure has been checked every year without resultant findings. Where findings have been identified, the partic ular procedure should be rechecked against other product lines until the findings have been rectified after which the independent audit procedure may revert back to the annual interval for the particular procedure. Provided that there are no safety related findings, the audit time periods specified in this AMC may be increased by up to 100% subject to agreement by the competent authority.

6. Where the organisation has more than one location approved the quality system should describe how these are integrated into the system and include a plan to audit each location every year.

7. A report should be raised each time an audit is carried out describing what was checked and the resulting findings against applicable requirements, procedures and products.

8. The independence of the audit should be established by always ensuring that audits are carried out by personnel not responsible for the function, procedure or products being checked.

9. An organisation should establish a quality plan acceptable to the competent authority to show when and how often the activities as required by M.A. Subpart G will be audited.

AMC M.A.712(f) Quality system

ED Decision 2015/029/R A small organisation is considered to be an organisation with up to 5 full - time staff (including all M.A.706 personnel) or equivalent proportional number when using part - time staff. The complexity of the organisation, combination of aircraft and aircraft types, the utilisation of the aircraft and the number of approved locations of the organisations should also be considered before replacing the quality system by an organisational review.

Appendix XIII to this AMC should be used to manage the organisational reviews.

The following activities should not be considered as subcontracting and, as a consequence, they may be performed without a quality system, although they need to be described in the continuing airworthiness management exposition and be approved by the compe tent authority: − Subscription to a technical publisher that provides maintenance data (Aircraft Maintenance Manuals, Illustrated Parts Catalogues, Service Bulletins, etc.), which may be applicable to a wide range of aircraft. These data may include maintenance schedules re commended by different manufacturers that can be afterwards used by the continuing airworthiness management organisation in order to produce customised maintenance programmes.

− Contracting the use of a software tool for the management of continuing airworthiness data and records, under the following conditions (in addition to M.A.714(d) and (e) ): − If the tool is used by several organisations, each organisation should have access to its own data only.

− Introduction of data can only be performed by personnel of the continuing airworthiness management organisation.

− The data can be retrieved at any time.

AMC M.A.801 Aircraft certificate of release to service after

embodiment of a Standard Change or a Standard Repair (SC/SR)

ED Decision 2023/013/R 1. Release to service and eligible persons Only natural or legal persons entitled to release to service an aircraft after maintenance in accordance with Part - M , Part - 145 or Part - CAO are considered as an eligible installer responsible for the embodiment of a SC/SR when in complianc e with applicable requirements.

For aircraft where there is no Part - 66 licence applicable, the release to service of an aircraft after embodiment of a SC/SR is only possible by holders of an appropriate certifying staff qualification valid in a Member State (national qualification), with the following conditions: − If the holder signs the release to service on behalf of an Approved Maintenance Organisation (AMO), this is valid for aircraft registered in any Member State.

− If the holder signs the release to service as an independent certifying staff (not on behalf of an AMO), this is only valid for aircraft registered in the Member State responsible for such certifying staff qualification.

Depending on its nature, for certain SCs/SRs, the Certification Specification CS - STAN might restrict the eligibility for the issuance of the release to service to certain persons.

Since the design of the SC/SR does not require specific approval, the natural or legal person releasing the aircraft to service after the embodiment of the change or repair takes the responsibility that the applicable c ertification s pecifications within CS - STAN are fulfilled while being in compliance with Part - M , Part - 145 and/or Part - CAO and not in conflict with data issued by the TC holder or the declarant of a declaration of design compliance . This includes responsibility in respect of an adequate design, the selection/manufacturing of suitable parts and their identification, documenting the change or repair, generation or amendment of aircraft manuals and instructions as needed, embodiment of the change/repair, releasing the aircraft to service and record - keeping.

2. Parts and appliances to be installed as part of a SC/SR The design of the parts and appliances to be used in a SC/SR is considered a part of the change/repair, and, therefore, there is no need of a specific design approval. However, it is possible that for a particular SC, these Certification Specifications spe cifically require the use of parts and appliances that meet a technical standard. In this case, when the parts and appliances require to be authorised as an ETSO article, other articles recognised as equivalent by means of Powered by EASA eRules Page 155 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS an international safety agreement or grandfathere d in accordance with Regulation (EU) No 748/2012 are equally acceptable.

Normally, a SC/SR shall not contain specifically designed parts that should be produced by a production organisation approved in accordance with Part - 21 (POA). However, in the case that the change or repair would contain such a part, it should be produced by an approved Production Organisation (POA), and delivered with an EASA Form 1. An arrangement in accordance with 21.A.122(b) is not applicable.

Eligibility for installation of parts and appliances belonging to a SC/SR is subject to compliance with the related provisions of Part 21 , Part 21 Light, Part - M , Part - 145 and Part - CAO , and the situation varies depending on the aircraft in/on which the SC/SR is to be embodied, and who the installer is. The need for an EASA Form 1 is addressed in Part 21 , Part 21 Light and Part - M .

Furthermore, Part - M Subpart F , Part - 145 and Part - CAO contain provisions (i.e. M.A.603(c) , 145.A.42(c) and CAO.A.020(c) ) allowing maintenance organisations to fabricate certain parts to be installed in/on the aircraft as part of their maintenance activities.

3. Parts and appliances identification The parts modified or installed during the embodiment of the SC/SR need to be permanently marked in accordance with Subpart Q of Part 21 or Subpart Q of Part 21 Light .

4. Documenting the SC/SR and declaring compliance with the Certification Specifications In accordance with Part - M , Part - CAO or Part - 145 (e.g. AMC M.A.801 (e) and AMC 145.A.50(b) ), the legal or natural person responsible for the embodiment of a change or a repair should compile details of the work accomplished. In the case of SCs/SRs, this includes, as necessary, based on its complexity, an engineering file containing drawings, a list of the parts and appliances used for the change or repair, supporting analysis and the results of tests performed or any other evidence suitable to show that the design fulfils the applicable Certification Specifications within CS - STAN together with a statement of compliance and amendments to aircraft manuals, to instructions for continuing airworthiness and to other documents such as aircraft parts list, wiring diagrams, etc., as de emed necessary. EASA Form 123 is prepared for the purpose of documenti ng the preparation and embodiment of the SC/SR. The aircraft logbook should contain an entry referring to EASA Form 123; both EASA Form 123 and the release to service required after the embodiment of the SC/SR should be signed by the same person.

Form 123 and all the records listed on it should follow elementary principles of controlled documentation, e.g. contain reference number of documents, issue dates, revision numbers, name of persons preparing/releasing the document, etc.

5. Record - keeping The legal or natural person responsible (see paragraph 1. above) for the embodiment of the change/repair should keep the records generated with the SC/SR as required by Part - M or Part - 145 and CS - STAN.

In addition, M.A.305 requires that the aircraft owner (or CAMO, if a contract i.a.w. M.A.201 exists) keeps the status of the changes/repairs embodied in/on the aircraft in order to control the aircraft configuration and manage its continuing airworthiness.

With regard to SCs/SRs, the information provided to the owner or CAMO may be listed in Form 123 and should include, as required, a copy of any modified aircraft manual and/or instructions for continuing airworthiness. All this information should normally b e consulted when the aircraft undergoes an airworthiness review, and, therefore, a clear system to record Powered by EASA eRules Page 156 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS the embodiment of SCs/SRs, which is also easily traceable, would be of help during subsequent aircraft inspections.

6. Instructions for continuing airworthiness As stipulated in M.A.302 , the aircraft owner or CAMO needs to assess if the changes in the instructions for continuing airworthiness of the aircraft require to amend the aircraft maintenance programme and to obtain its approval.

7. Embodiment of more than one SC The embodiment of two or more related SCs described in Subpart B of CS - STAN is permitted as a single change (the use of one Form 123 only) as long as adequate references to and records of all SCs embodied are captured. Restrictions and limitations of the t wo (or more) SCs would apply. It is permitted to issue a single release to service containing adequate traceability of all the SCs embodied.

AMC M.A.801(f ) Aircraft certificate of release to service

ED Decision 2023/013/R INCOMPLETE MAINTENANCE 1. Being unable to establish full compliance with sub - paragraph M.A.801(b) means that the maintenance required by the aircraft owner , CAO or CAMO could not be completed due either to running out of available aircraft maintenance downtime or because the maintenance data requires a flight to be performed as part of the maintenance, as described in paragraph 4.

2. The aircraft owner , CAO or CAMO is responsible for ensuring that all required maintenance has been carried out before flight. Therefore , an aircraft owner , CAO or CAMO should be informed and agree to the deferme nt of full compliance with M.A.801(b) . The certificate of release to service may then be issued subject to details of the deferment, including the aircraft owner , CAO or CAMO authorisation, being endorsed on the certificate.

3. If a CRS is issued with incomplete maintenance a record should be kept stating what action the mechanic, supervisor and certifying staff should take to bring the matter to the attention of the relevant aircraft owner , CAO or CAMO so that the issue may be discussed and resolved with the aircraft owner , CAO or CAMO.

4. Certain maintenance data issued by the design approval holder or the declarant of a declaration of design compliance (e.g. aircraft maintenance manual (AMM)) require s that a maintenance task be performed in flight as a necessary condition to complete the maintenance ordered.

Within the aircraft limitations, the person authorised to certify the maintenance per M.A.801 should release the incomplete maintenance before this flight. GM M.A.301(i) describes the relations with the aircraft operator, which retains the responsibility for the MCF.

GM M.A.901 Airworthiness review

ED Decision 2023/013/R Responsibilities of airworthiness review staff: The following is a summary of the requirements contained in M.A.901 as well as the associated AMC and Appendices, in relation to the responsibilities of the airworthiness review staff: − Airworthiness review staff are responsible for performing both the documental and the physical survey.

− Procedures must be established by the CAMO or CAO in order to perform the airworthiness review, including the depth of samplings.

− Procedures must make very clear that the final word about the depth of the inspections (both documental and physical) belongs to the airworthiness review staff, who can go beyond the depth established in the CAME or CAE if they find it necessary. At the en d, it is the responsibility of the airworthiness review staff to be satisfied that the aircraft complies with Part - M and is airworthy, and the organisation must ensure that no pressure or restrictions are imposed on the airworthiness review staff when perf orming their duty.

− A compliance report must be produced by the airworthiness review staff, detailing all items checked and the outcome of the review.

− Airworthiness review staff are responsible for the items checked during the airworthiness review. However, they do not take over the responsibilities of the CAMO, maintenance organisation, DOA, POA or any other organisations, not being responsible for prob lems not detected during the airworthiness review or for the possibility that the approved or declared maintenance programme may not include certain recommendations from the design approval holder or the declarant of a declaration of design compliance . Obv iously, if the airworthiness review staff are not independent of the airworthiness management process and were nominated on the basis of the option of having overall authority on such a process, they will be responsible for the full continuing airworthines s of such aircraft. Nevertheless, this responsibility will be a consequence of their position in the organisation and not of their function as airworthiness review staff.

It is the responsibility of the owner or contracted CAMO or CAO to ensure that the aircraft is fully airworthy at any time.

AMC M.A.901(b) Aircraft airworthiness review

ED Decision 2016/011 /R 1. If the continuing airworthiness of the aircraft is not managed according to an Appendix I Continuing airworthiness contract , the aircraft should be considered to be outside a controlled environment. Nevertheless, such contract is not necessary when the operator and the CAMO are the same organisation.

2. The fact that limited pilot - owner maintenance as defined in M.A.803(b) is not carried out and released by an approved maintenance organisation does not change the status of an aircraft in a controlled environment providing the CAMO under contract has been informed of any such maintenance carried out.

AMC M.A.901(c)2, (e)2 and (f) Aircraft airworthiness review

ED Decision 2015/029/R When the aircraft has remained within a controlled environment, the extension of the validity of the airworthiness review certificate does not require an airworthiness review but only a verification of the continuous compliance with M.A.901(b) .

It is acceptable to anticipate the extension of the airworthiness review certificate by a maximum of 30 days without a loss of continuity of the airworthiness review pattern, which means that the new expiration date is set up one year after the previous ex piration date. This anticipation of up to 30 days also applies to the 12 month requirements shown in M.A.901(b) , meaning that the aircraft is still considered as being in a controlled environment if it has been continuously managed by a single organisation and maintained by appropriately approved organisations, as stated in M.A.901(b) , from the date when the last airworthiness review certificate was issued until the date when the extension is performed (this can be up to 30 days less than 12 months).

It is also acceptable to perform the extension of an airworthiness review certificate after its expiration date, as long as all the conditions for the extension are met. However, this means the following: − The aircraft could not fly since the airworthiness review certificate expired until it is extended, and − The new expiration date (after extension) is set one year after the previous expiration date (not one year after the extension is performed).

AMC M.A.901(d) Aircraft airworthiness review

ED Decision 2023/013/R The recommendation sent by a CAMO or CAO to the competent authority of the Member State of registry should be, at least, in English when the Member State of registry is different from the CAMO /CAO ’s Member State. Otherwise , it can be completed in the official language(s) of the CAMO /CAO ’s Member State.

The recommendation sent to the competent authority should contain at least the items described below: (a) General information − CAMO information − owner/lessee information − date and place where the document review and the aircraft survey were carried out Powered by EASA eRules Page 168 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS − period and place the aircraft can be seen if required by the competent authority (b) Aircraft information − registration − type − manufacturer − serial number − flight manual reference − weight and centre of gravity data − maintenance programme reference (c) Documents accompanying the recommendation − copy of registration papers − copy of the owners request for a new airworthiness review certificate (d) Aircraft status − aircraft total time and cycles − list of persons or organisations having carried out continuing airworthiness activities including maintenance tasks on the aircraft and its components since the last airworthiness review certificate (e) Aircraft survey − a precise list of the areas of the aircraft that were surveyed and their status (f) Findings − a list of all the findings made during the airworthiness review with the corrective action carried out (g) Statement A statement signed by the airworthiness review staff recommending the issue of an airworthiness review certificate.

The statement should confirm that the aircraft in its current configuration complies with the following: − airworthiness directives up to the latest published issue, and; − type certificate datasheet or airworthiness data sheet (for aircraft subject to a declaration of design compliance) ; − maintenance programme; − limitation for life - limited parts and time - controlled components ; − the valid weight and centre of gravity schedule reflecting the current configuration of the aircraft; − Part 21 or Part 21 Light, as applicable, for all modifications and repairs; − the current flight manual including supplements, and; Powered by EASA eRules Page 169 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS − operational requirements.

The above items should clearly state the exact reference of the data used in establishing compliance; for instance , the number and issue of the type certificate data sheet or airworthiness data sheet (for aircraft subject to a declaration of design compliance) used should be stated.

The statement should also confirm that all the above is properly entered in the aircraft continuing airworthiness record system and/or in the operator’s technical log.

AMC M.A.901(i ) Aircraft airworthiness review

ED Decision 2020/002/R Suitable accommodation should include: (a) an office with normal office equipment such as desks, telephones, photocopying machines etc.

whereby the continuing airworthiness records can be reviewed.

(b) a hangar when needed for the physical survey.

2. The CAMO or CAO should develop procedures for the airworthiness review staff to produce a compliance report that confirms the above have been reviewed and found in compliance with Part - M.

AMC M.A.901(l) and (m) Aircraft airworthiness review

ED Decision 2020/002/R PHYSICAL SURVEY 1. The physical survey could require actions categorised as maintenance (e.g. operational tests, tests of emergency equipment, visual inspections requiring panel opening, etc.). In this case, after the airworthiness review, a release to service should be issued.

2. When the airworthiness review staff are not appropriately qualified as per Part - 66 in order to release such maintenance, M.A.901(l) requires them to be assisted by such qualified personnel.

However, the function of such Part - 66 personnel is limited to performing and releasing the maintenance actions requested by the airworthiness review staff, it not being their function to perform th e physical survey of the aircraft.

3. This means that the airworthiness review staff who is going to sign the airworthiness review certificate or the recommendation should be the one performing both the documented review and the physical survey of the aircraft. It is not the intent of the rule to delegate the survey to Part - 66 personnel who are not airworthiness review staff. Furthermore, the provision of M.A.901(n) that allows a 90 - day anticipation for the physical survey provides enough flexibility to ensure that the airworthiness review staff (ARS) are present.

4. The physical survey may include verifications to be carried out during flight.

5. The CAMO or CAO should develop procedures for the ARS to produce a compliance report that confirms that the physical survey has been carried out and found satisfactory.

6. To ensure compliance, the physical survey may include relevant sample checks of items.

AMC M.A.901(n) Aircraft airworthiness review

ED Decision 2020/002/R ‘Without loss of continuity of the airworthiness review pattern’ means that the new expiration date is set up 1 year after the previous expiration date. As a consequence, when the airworthiness review is anticipated, the validity or the airworthiness revie w certificate is longer than 1 year (up to 90 days longer).

This anticipation of up to 90 days also applies to the 12 - month requirements shown in M.A.901(b) , which means that the aircraft is still considered as being in a controlled environment if it has been continuously managed by a single organisation and maintained by appropriately approved organisations, as stated in M.A.901(b) , from the date when the last airworthiness review certificate was issued until the date when the new airworthiness review is performed (this can be up to 90 days less than 12 months).

M.B.601 Application

Regulation (EU) No 1321/2014 Where maintenance facilities are located in more than one Member State the investigation and continued oversight of the approval shall be carried out in conjunction with the competent authorities designated by the Member States in whose territory the other maintenance facilities are located.

M.B. 602 Initial Approval

Regulation (EU) 2019/1383 (a) Provided the requirements of points M.A.606(a) and (b) are complied with, the competent authority shall formally indicate its acceptance of the M.A.606(a) and (b) personnel to the applicant in writing.

(b) The competent authority shall establish that the procedures specified in the maintenance organisation manual comply with Subpart F of this Annex, and shall ensure that the accountable manager signs the commitment statement.

(c) The competent authority shall verify that the organisation is in compliance with the requirements laid down in Subpart F of this Annex.

(d) A meeting with the accountable manager shall be convened at least once during the investigation for approval to ensure that he/she fully understands the significance of the approval and the reason for signing the commitment of the organisation to complianc e with the procedures specified in the manual.

(e) All findings shall be confirmed in writing to the applicant organisation.

(f) The competent authority shall record all findings, closure actions (actions required to close a finding) and recommendations.

(g) For initial approval all findings shall be corrected by the organisation and closed by the competent authority before the approval can be issued.

AMC M.B.602(a) Initial approval

ED Decision 2015/029/R 1. ‘Formally indicate in writing’ means that an EASA Form 4 ( Appendix X to AMC M.B.602(a) and AMC M.B.702(a) ) should be used for this activity. With the exception of the accountable manager, an EASA Form 4 should be completed for each person nominated to hold a position required by M.A.606(b) .

2. In the case of the accountable manager approval of the maintenance organisation manual containing the accountable manager’s signed commitment statement constitutes formal acceptance.

AMC M.B.602(b) Initial approval

ED Decision 2015/029/R The competent authority should indicate approval of the maintenance organisation manual in writing.

A MC M.B.602(c) Initial approval

ED Decision 2015/029/R 1. The competent authority should determine by whom, and how the audit shall be conducted.

For example, it will be necessary to determine whether one large team audit or a short series of small team audits or a long series of single man audits are most approp riate for the particular situation.

2. The audit may be carried out on a product line type basis. For example, in the case of an organisation with Socata TB20 and Piper PA28 ratings, the audit is concentrated on one type only for a full compliance check. Dependent upon the result, the second ty pe may only require a sample check that should at least cover the activities identified as weak for the first type.

3. The competent authority auditing surveyor should always ensure that he/she is accompanied throughout the audit by a senior technical member of the organisation. The reason for being accompanied is to ensure the organisation is fully aware of any findings d uring the audit.

4. The auditing surveyor should inform the senior technical member of the organisation at the end of the audit visit on all findings made during the audit.

AMC M.B.602(e) Initial approval

ED Decision 2015/029/R 1. Findings should be recorded on an audit report form with a provisional categorisation as a level 1 or 2. Subsequent to the audit visit that identified the particular findings, the competent authority should review the provisional finding levels, adjusting them if necessary and change the categorisation from ‘provisional’ to ‘confirmed’.

2. All findings should be confirmed in writing to the applicant organisation within 2 weeks of the audit visit.

3. There may be occasions when the competent authority finds situations in the applicant's organisation on which it is unsure about compliance. In this case, the organisation should be informed about possible non - compliance at the time and the fact that th e situation will be reviewed within the competent authority before a decision is made. If the review concludes that there is no finding then a verbal confirmation to the organisation will suffice.

AMC M.B.602(f) Initial approval

ED Decision 2015/029/R 1. The audit report should be made on an EASA Form 6F (see appendix VI).

2. A quality review of the EASA Form 6F audit report should be carried out by a competent independent person nominated by the competent authority. The review should take into account the relevant paragraphs of M.A. Subpart F , the categorisation of finding levels and the closure action taken. Satisfactory review of the audit form should be indicated by a signature on the EASA Form 6F .

AMC M.B.602(g) Initial approval

ED Decision 2015/029/R The audit reports should include the date each finding was cleared together with reference to the competent authority report or letter that confirmed the clearance.

M.B.603 Issue of approval

Regulation (EU) 2019/1383 (a) The competent authority shall issue to the applicant an EASA Form 3 approval certificate ( Appendix V to this Annex), which includes the extent of the approval, when the maintenance organisation is in compliance with the applicable points of this Annex.

(b) The competent authority shall indicate the conditions attached to the approval on the EASA Form 3 approval certificate.

AMC M.B.603(a) Issue of approval

ED Decision 2015/029/R 1. For approvals involving more than one competent authority, the approval should be granted in conjunction with the competent authorities of the Member States in whose territories the other maintenance organisation facilities are located. For practical reaso ns the initial approval should be granted on the basis of a joint audit visit by the approving competent authority and competent authorities of the Member States in whose territories the other maintenance organisation facilities are located. Audits rela ted to the continuation of the approval should be delegated to the competent authorities of the Member States in whose territories the other maintenance organisation facilities are located. The resulting audit form and recommendation should then be submitt ed to the approving competent authority.

2. The approval should be based upon the organisational capability relative to M.A. Subpart F compliance and not limited by reference to individual EASA certificated products.

For example, if the organisation is capable of maintaining within the limitation of M.A. Subpart F the Cessna 100 series aircraft the approval schedule should state A2 Cessna 100 series and not Cessna 172RG which is a particular designator for one of many Cessna 100 series.

3. Special case for ELA1 aircraft: In order to promote standardisation, for this category of aircraft the following approach is recommended: − Possible ratings to be endorsed in EASA Form 3: − ELA1 sailplanes; − ELA1 powered sailplanes and ELA1 aeroplanes; − ELA1 balloons; − ELA1 airships.

− Before endorsing any of those ratings (for example, ELA1 sailplanes) in EASA Form 3, the competent authority should audit that the organisation is capable of maintaining at least one aircraft type (for example, one type of sailplanes within the ELA1 catego ry), including Powered by EASA eRules Page 194 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION B — PROCEDURE FOR COMPETENT AUTHORITIES the availability of the necessary facilities, equipment, tooling, material, maintenance data, and certifying staff.

− It is acceptable that the detailed scope of work in the Maintenance Organisation Manual (MOM) contains the same ratings endorsed in EASA Form 3 (for example, ELA1 sailplanes), without a need to further limit them. However, the maintenance organisation will only be able to maintain a certain aircraft type when all the necessary facilities, equipment, tooling, material, maintenance data, and certifying staff are available.

AMC M.B.603(c) Issue of approval

ED Decision 2015/029/R The numeric sequence of the approval reference should be unique to the particular approved maintenance organisation.

M.B.604 Continuing oversight

Regulation (EU) 2019/1383 (a) The competent authority shall keep and update a programme listing, for each maintenance organisation approved in accordance with Subpart F of Section B of this Annex under its supervision, the dates when audit visits are due and when such visits were carried out.

(b) Each organisation shall be completely audited at periods not exceeding 24 months.

(d) The competent authority shall record all findings, closure actions (actions required to close a finding) and recommendations.

(e) A meeting with the accountable manager shall be convened at least once every 24 months to ensure he/she remains informed of significant issues arising during audits.

AMC M.B.604(b) Continuing oversight

ED Decision 2020/002/R 1. Where the competent authority has decided that a series of audit visits are necessary to arrive at a complete audit of an approved maintenance organisation, the program should indicate which aspects of the approval will be covered on each visit.

2. It is recommended that part of an audit concentrates on the organisations internal self monitoring reports produced by the organisational review to determine if the organisation is identifying and correcting its problems.

3. At the successful conclusion of the audit(s) including verification of the manual, an audit report form should be completed by the auditing surveyor including all recorded findings, closure actions and recommendation. An EASA Form 6F should be used for this activity.

4. Credit may be claimed by the competent authority surveyor(s) for specific item audits completed during the preceding 23 - month period subject to four conditions: (a) the specific item audit should be the same as that required by M.A. Subpart F latest amendment, and (b) there should be satisfactory evidence on record that such specific item audits were carried out and that all corrective actions have been taken, and Powered by EASA eRules Page 195 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION B — PROCEDURE FOR COMPETENT AUTHORITIES (c) the competent authority surveyor(s) should be satisfied that there is no reason to believe standards have deteriorated in respect of those specific item audits being granted a back credit; (d) the specific item audit being granted a back credit should be audited not later than 24 months after the last audit of the item.

5. When performing the oversight of an organisation that holds more than one approval pursuant to this Regulation , the competent authority should arrange the audits to cover both approvals avoiding a duplicated visit of a particular area.

M.B.605 Findings

Regulation (EU) 2019/1383 (a) When during audits or by other means evidence is found showing non - compliance with a requirement laid down in this Annex or Annex Vb (Part - ML), the competent authority shall take the following actions: 1. For level 1 findings, immediate action shall be taken by the competent authority to revoke, limit or suspend in whole or in part, depending upon the extent of the level 1 finding, the maintenance organisation approval, until successful corrective action ha s been taken by the organisation.

2. For level 2 findings, the competent authority shall grant a corrective action period appropriate to the nature of the finding that shall not be more than three months. In certain circumstances, at the end of this first period and subject to the nature of t he finding, the competent authority can extend the three month period subject to a satisfactory corrective action plan.

(b) Action shall be taken by the competent authority to suspend in whole or part the approval in case of failure to comply within the timescale granted by the competent authority.

AMC M.B.605(a)(1) Findings

ED Decision 2015/029/R For a level 1 finding it may be necessary for the competent authority to ensure that further maintenance and re - certification of all affected products is accomplished, dependent upon the nature of the finding.

M.B.606 Changes

Regulation (EU) 2019/1383 (a) The competent authority shall comply with the applicable elements of the initial approval for any change to the organisation notified in accordance with point M.A.617 .

(b) The competent authority may prescribe the conditions under which the approved maintenance organisation may operate during such changes, unless it determines that the approval should be suspended due to the nature or the extent of the changes.

(c) For any change to the maintenance organisation manual: 1. in the case of direct approval of changes in accordance with point (b) of point M.A.604 , the competent authority shall verify that the procedures specified in the manual are in compliance with this Annex before formally notifying the approved organisation of the approval; Powered by EASA eRules Page 196 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION B — PROCEDURE FOR COMPETENT AUTHORITIES 2. in the case of an indirect approval of changes in accordance with point (c) of point M.A.604 , the competent authority shall ensure that: (i) the changes remain minor; (ii) it has adequate control over the approval of the changes to ensure they remain in compliance with the requirements of this Annex.

AMC M.B.606 Changes

ED Decision 2015/029/R 1. Changes in nominated persons.

The competent authority should have adequate control over any changes to personnel specified in M.A.606(a) and (b) . Such changes will require an amendment to the manual.

2. It is recommended that a simple manual status sheet is maintained which contains information on when an amendment was received by the competent authority and when it was approved.

3. The competent authority should define the minor amendments to the manual which may be incorporated through indirect approval. In this case a procedure should be stated in the amendment section of the maintenance organisation manual.

Changes notified in accordance with M.A.617 are not considered minor.

For all cases other than minor, the applicable part(s) of the EASA Form 6F should be used for the change.

4. The approved maintenance organisation should submit each manual amendment to the competent authority whether it be an amendment for competent authority approval or an indirectly approved amendment. Where the amendment requires competent authority approval, the competent authority when satisfied, should indicate its approval in writing. Where the amendment has been submitted under the indirect approval procedure the competent authority should acknowledge receipt in writing.

M.B.607 Revocation, suspension and limitation of an approval

Regulation (EU) No 1321/2014 The competent authority shall: (a) suspend an approval on reasonable grounds in the case of potential safety threat, or; (b) suspend, revoke or limit an approval pursuant to point M.B.605 .

AMC M.B.702(a) Initial approval

2. In the case of the accountable manager, approval of the continuing airworthiness management exposition containing the accountable manager’s signed commitment statement constitutes formal acceptance, once the authority has held a meeting with the accountabl e manager and is satisfied with its results.

AMC M.B.702(b) Initial approval

ED Decision 2016/011 /R 1. The competent authority should indicate approval of the continuing airworthiness management exposition in writing.

2. Contracts for sub - contracting continuing airworthin ess management tasks by CAMO s should be included in the continuing airworthiness organisation exposition. The competent authorities should verify that the standa rds set forth in AMC M.A.711(a)(3) have been met when approving the exposition.

3. The competent authority while investigating the acceptability of the proposed subcontracted continuing airworthiness management tasks arrangements will take into account, in the subcontracted organisation, all other such contracts that are in place irrespective of state of registry in terms of sufficiency of resources, expertise, management structure, facilities and liai son between the CAMO , the subcontracted organisation and , where applicable , the contracted maintenance organisation(s).

AMC M.B.702(c) Initial approval

ED Decision 2015/029/R 1. The competent authority should determine by whom, and how the audit shall be conducted.

Powered by EASA eRules Page 199 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION B — PROCEDURE FOR COMPETENT AUTHORITIES 2. The audit may be carried out on a product line type basis. For example, in the case of an organisation with Airbus A320 and Airbus A310 ratings, the audit is concentrated on one type only for a full compliance check. Dependent upon the result, the second t ype may only require a sample check that should at least cover the activities identified as weak for the first type.

3. When determining the scope of the audit and which activities of the organisation will be assessed during the audit, the privileges of the approved organisation should be taken into account, e.g. approval to carry out airworthiness reviews.

4. The competent authority auditing surveyor should always ensure that he/she is accompanied throughout the audit by a senior technical member of the organisation. Normally this is the quality manager. The reason for being accompanied is to ensure the organis ation is fully aware of any findings during the audit.

5. The auditing surveyor should inform the senior technical member of the organisation at the end of the audit visit on all findings made during the audit.

M.B.703 Issue of approval

Regulation (EU) 20 20 / 270 (a) The competent authority shall issue to the applicant an EASA Form 14 - MG approval certificate ( Appendix VI to this Annex ) which includes the extent of approval, when the continuing airworthiness management organisation is in compliance with Section A, Subpart G of this Annex (Part - M).

(b) The competent authority shall indicate the validity of the approval on the EASA Form 14 - MG approval certificate.

(c ) The reference number shall be included on the Form 14 - MG approval certificate in a manner specified by the Agency.

(d) In the case of licenced air carriers in accordance with Regulation (EC) No 1008/2008, the information contained on an EASA Form 14 - MG will be included on the air operator's certificate.

A MC M.B.703 Issue of approval

ED Decision 2015/029/R The table shown for the Approval Schedule in EASA Form 14 includes a field designated as ‘Aircraft type/series/group’ The intention is to give maximum flexibility to the competent authority to customise the approval to a particular organisation.

Possible alternatives to be included in this field are the following: − A specific type designation that is part of a type certificate, such as Airbus 340 - 211 or Cessna 172R.

− A type rating (or series) as listed in Part - 66 Appendix I to AMC , which may be further subdivided, such as Boeing 737 - 600/700/800, Boeing 737 - 600, Cessna 172 Series.

− An aircraft group such as, for example, ‘all sailplanes and powered sailplanes’ or ‘Cessna single piston engined aircraft’ or ‘Group 3 aircraft’ (as defined in 66.A.5 ) or ‘aircraft below 2 730 kg MTOM’.

Reference to the engine type installed in the aircraft may or may not be included, as necessary.

It is important to note that the scope of work defined in EASA Form 14 is further limited to the one defined in the Continuing Airworthiness Management Exposition (CAME). It is this scope of work in the CAME which ultimately defines the approval of the org anisation. As a consequence, it is possible for a competent authority to endorse in EASA Form 14, for example, a scope of work for Group 3 aircraft while the detailed scope of work defined in the CAME does not include all Group 3 aircraft.

Nevertheless, in all cases, the competent authority should be satisfied that the organisation has the capability to manage the types/groups/series endorsed in the EASA Form 14 .

Since the activities linked to continuing airworthiness management are mainly process - oriented rather than facility/tooling - oriented, changes to the detailed scope of work defined in the CAME (either directly or through a capability list), within the limit s already included in EASA Form 14 , may be considered as not affecting the approval and not subject to M.A.713 . As a consequence, for these changes the competent authority may allow the use by the CAMO of the indirect approval procedure defined in M.A.704(c) .

In the example mentioned above, before endorsing the Group 3 in EASA Form 14 for the first time, the competent authority should make sure that the organisation is capable of managing this category Powered by EASA eRules Page 201 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION B — PROCEDURE FOR COMPETENT AUTHORITIES of aircraft as a whole. In particular, the competent authority should ensure that Baseline/Generic Maintenance Programmes (see M.A.709 ) or individual maintenance programmes (for contracted customers) are available for all the aircraft which are intended to be initially included in the scope of work detailed in the CAME. Later on, if changes need to be introduced in the detailed scope of work detailed in the CAME to include new aircraft types (within Group 3), this may be done by the CAMO through the use of the indirect approval procedure.

Since, as mentioned above, the competent authority should make sure that the organisation is capable of managing the requested category as a whole, it is not reasonable to grant a full Group 3 approval based on an intended scope of work which is limited to , for example, a Cessna 172 aircraft. However, it may be reasonable to grant such full Group 3 approval, after showing appropriate capability, for an intended scope of work covering several aircraft types or series of different complexity and which are r ep resentative of the full Group 3.

Special case for ELA1 aircraft: In order to promote standardisation, for this category of aircraft the following approach is recommended: − Possible ratings to be endorsed in EASA Form 14 : − ELA1 sailplanes; − ELA1 powered sailplanes and ELA1 aeroplanes; − ELA1 balloons; − ELA1 airships.

− Before endorsing any of those ratings (for example, ELA1 sailplanes) in EASA Form 14 , the competent authority should audit that the organisation is capable of managing at least one aircraft type (for example, one type of sailplanes within the ELA1 category), including the availability of the necessary facilities, data, maintenance program mes, and staff.

− It is acceptable that the detailed scope of work in the CAME contains the same ratings endorsed in EASA Form 14 (for example, ELA1 sailplanes), without a need to further limit them. However, the CAMO will only be able to manage a certain aircraft type when all the necessary facilities, data, maintenance programmes and staff are available.

AMC M.B.703(a) Issue of approval

ED Decision 2015/029/R For approvals involving more than one competent authority, the approval should be granted in conjunction with the competent authority of the Member States in whose territories the other continuing airworthiness management organisation facilities are locate d. For practical reasons the initial approval should be granted on the basis of a joint audit visit by the approving competent authority and competent authority of the Member States in whose territories the other continuing airworthiness management organis ation facilities are located. Audits related to the renewal of the approval should be delegated to the competent authority of the Member States in whose territories the other continuing airworthiness management organisation facilities are located.

(e) The competent authority shall record all findings, closure actions (actions required to close a finding) and recommendations.

(f) A meeting with the accountable manager shall be convened at least once every 24 months to ensure he/she remains informed of significant issues arising during audits.

AMC M.B.704(b) Continuing oversight

ED Decision 2020/002/R 1. Where the competent authority has decided that a series of audit visits are necessary to arrive at a complete audit of an approved continuing airworthiness management organisation, the program should indicate which aspects of the approval will be covered o n each visit.

2. It is recommended that part of an audit concentrates on two ongoing aspects of the M.A. Subpart G approval, namely the organisations internal self monitoring quality reports produced by the quality monitoring personnel to determine if the organisation is identifying and correcting its problems and secondly the number of concessions granted by the qual ity manager.

3. At the successful conclusion of the audit(s) including verification of the exposition, an audit report form should be completed by the auditing surveyor including all recorded findings, closure actions and recommendation. An EASA Form 13 should be used for this activity.

4. Credit may be clai med by the competent authority s urveyor(s) for specific item audits completed during the preceding 23 month period subject to four conditions: (a) the specific item audit should be the same as that required by M.A. Subpart G latest amendment, and (b) there should be satisfactory evidence on record that such specific item audits were carried out and that all corrective actions have been taken, and (c) the competent authority surveyor(s) should be satisfied that there is no reason to believe standards have deteriorated in respect of those specific item audits being granted a back credit; Powered by EASA eRules Page 203 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) SECTION B — PROCEDURE FOR COMPETENT AUTHORITIES (d) the specific item audit being granted a back credit should be audited not later than 24 months after the last audit of the item.

5. When a CAMO sub - contracts continuing airworthiness management tasks all sub - contracted organisations should also be audited by the competent authority at periods not exceeding 24 months (credits per paragraph 4 above are permitted) to ensure they fully comply with M.A. Subpart G . For these audits, the competent authority auditing surveyor should always ensure that he/she is accompanied throughout the audit by a senior technical member of the CAMO .

AMC to Appendix II to Part - M — Use of the EASA Form 1 for

maintenance

ED Decision 2015/029/R 1. The following formats of an issued EASA Form 1 or equivalent certificate are acceptable: − A paper certificate bearing a signature (both originals and copies are accepted); − A paper certificate generated from an electronic system (printed from electronically stored data) when complying with the following subparagraph 2; − An electronic EASA Form 1 or equivalent when complying with the following subparagraph 2.

2. Electronic signature and electronic exchange of the EASA Form 1 a) Submission to the competent authority Any organisation intending to implement an electronic signature procedure to issue EASA Form 1 and/or to exchange electronically such data contained on the EASA Form 1 , should document it and submit it to the competent authority as part of the documents attached to its exposition.

b) Characteristics of the electronic system generating the EASA Form 1 The electronic system should: − guarantee secure access for each certifying staff; − ensure integrity and accuracy of the data certified by the signature on the form and be able to show evidence of the authenticity of the EASA Form 1 (recording and record keeping) with suitable security, safeguards and backups; − be active only at the location where the part is being released with an EASA Form 1 ; − not permit to sign a blank form; − provide a high degree of assurance that the data has not been modified after signature (if modification is necessary after issuance, i.e., re - certification of a part, a new form with a new number and reference to the initial issuance should be made).

− provide for a ‘personal’ electronic signature, identifying the signatory. The signature should be generated only in presence of the signatory.

An electronic signature means data in electronic form which is attached to or logically associated with other electronic data and which serves as a method of authentication and should meet the following criteria: − it is uniquely linked to the signatory; − it is capable of identifying the signatory; − it is created using means that the signatory can maintain under his sole control.

This electronic signature should be an electronically generated value based on a cryptographic algorithm and appended to data in a way to enable the verification of the data’s source and integrity.

Powered by EASA eRules Page 222 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) APPENDICES TO ANNEX I (Part - M) Organisation(s) are reminded that additional national and/or European requirements may need to be satisfied when operating electronic systems. ‘Directive 1999/93/EC of the European Parliament and of the Council of 13 December 1999 on a Community framework for electronic signatures’, as last amended, may constitute a reference.

The electronic system should be based on a policy and management structure (confidentiality, integrity and availability), such as: − Administrators, signatories; − Scope of authorisation, rights; − Password and secure access, authentication, protections, confidentiality; − Track changes; − Minimum blocks to be completed, completeness of information; − Archives; − etc.

The electronic system generating the EASA Form 1 may contain additional data such as; − Manufacturer code; − Customer identification code; − Workshop report; − Inspection results; − etc.

c) Characteristics of the EASA Form 1 generated from the electronic system.

To facilitate understanding and acceptance of the EASA Form 1 released with an electronic signature, the following statement should be in Block 14b : ‘Electronic Signature on File’.

In addition to this statement, it is accepted to print or display a signature in any form, such as a representation of the hand - written signature of the person signing (i.e. scanned signature) or a representation of their name.

When printing the electronic form, the EASA Form 1 should meet the general format as specified in Appendix II to Part - M . A watermark - type ‘PRINTED FROM ELECTRONIC FILE’ should be printed on the document.

When the electronic file contains a hyperlink to data required to determine the airworthiness of the item(s), the data associated to the hyperlink, when printed, should be in a legible format and be identified as a reference from the EASA Form 1 .

Additional information not required by the EASA Form 1 completion instructions may be added to the printed copies of EASA Form 1 , as long as the additional data do not prevent a person from filling out, issuing, printing, or reading any portion of the EASA Form 1 . This additional data should be provided only in block 12 unless it is necessary to include it in another block to clarify the content of that block.

Both parties (issuer and receiver) should agree on electronic transfer of the EASA Form 1 .

For that purpose, the exchange needs to include: − all data of the EASA Form 1 , including referenced data required by the EASA Form 1 completion instructions; − all data required for authentication of the EASA Form 1 .

− In addition, the exchange may include: − data necessary for the electronic format; − additional data not required by the EASA Form 1 completion instructions, such as manufacturer code, customer identification code.

− The system used for the exchange of the electronic EASA Form 1 should provide: − A high level of digital security; the data should be protected, not altered or not corrupted; − Traceability of data back to its source.

Trading partners wishing to exchange EASA Form 1 electronically should do so in accordance with the means of compliance stated in this document. It is recommended that they use an established, common, industry method such as Air Transport Association (ATA) Spec 2000 Chapter 16.

The organisation(s) are reminded that additional national and/or European requirements may need to be satisfied when operating the electronic exchange of the electronic EASA Form 1 .

The receiver should be capable of regenerating the EASA Form 1 from the received data without alteration; if not, the system should revert back to the paper system.

When the receiver needs to print the electronic form, refer to subparagraph c) here above.

Appendix IV — Class and rating system for the terms of approval of

maintenance organisations referred to in Annex I (Part - M),

Subpart F

Regulation (EU) 2021/1963 1. Except as stated otherwise for the smallest organisations referred to in point 11, the table in point 12 provides for the standard system for the approval of a maintenance organisation referred to in Annex I (Part - M), Subpart F . An organisation must be granted an approval that ranges from a single class and rating with limitations to all classes and ratings with limitations.

2. In addition to the table referred to in point 12, the approved maintenance organisation is required to indicate its scope of work in its maintenance organisation manual.

3. Within the approval class(es) and rating(s) granted by the competent authority, the scope of work specified in the maintenance organisation exposition defines the exact limits of approval.

It is therefore essential that the approval class(es) and rating (s) and the organisations scope of work are matching.

4. A category A class rating means that the approved maintenance organisation may carry out maintenance on the aircraft and any component (including engines and/or Auxiliary Power Units (APUs), in accordance with aircraft maintenance data or, if agreed by the competent authority, in accordance with component maintenance data, only whilst such components are fitted to the aircraft. Nevertheless, such A - rated approved maintenance organisation may temporarily remove a component for maintenance, in order to imp rove access to that component, except when such removal generates the need for additional maintenance not eligible for the provisions of this point. This will be subject to a control procedure in the maintenance organisation exposition to be approved by th e competent authority. The limitation section will specify the scope of such maintenance thereby indicating the extent of approval.

5. A category B class rating means that the approved maintenance organisation may carry out maintenance on the uninstalled engine and/or APU and engine and/or APU components, in accordance with engine and/or APU maintenance data or, if agreed by the competent authority, in accordance with component maintenance data, only whilst such components are fitted to the engine and/or APU. Nevertheless, such B - rated approved maintenance organisation may temporarily remove a component for maintenance, in order to impr ove access to that component, except when such removal generates the need for additional maintenance not eligible for the provisions of this point. The limitation section will specify the scope of such maintenance thereby indicating the extent of approval. A maintenance organisation approved with a category B class rating may also carry out maintenance on an installed engine during ‘base’ and ‘line’ maintenance subject to a control procedure in the maintenance organisation exposition to be approved by the c ompetent authority. The maintenance organisation exposition scope of work shall reflect such activity where permitted by the competent authority.

6. A category C class rating means that the approved maintenance organisation may carry out maintenance on uninstalled components (excluding engines and APUs) intended for fitment to the aircraft or engine/APU. The limitation section will specify the scope of such maintenance thereby indicating the extent of approval. A maintenance organisation approved with a category C class rating may also carry out maintenance on an installed component during base and line maintenance or at an engine/APU maintenance fac ility subject to a control procedure in the maintenance organisation exposition to be approved by the competent authority. The Powered by EASA eRules Page 228 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) APPENDICES TO ANNEX I (Part - M) maintenance organisation exposition scope of work shall reflect such activity where permitted by the competent authority.

7. A category D class rating is a self contained class rating not necessarily related to a specific aircraft, engine or other component. The D1 — Non Destructive Testing (NDT) rating is only necessary for an approved maintenance organisation that carries out NDT as a particular task f or another organisation. A maintenance organisation approved with a class rating in A or B or C category may carry out NDT on products it is maintaining subject to the maintenance organisation exposition containing NDT procedur es, without the need for a D1 class rating.

8. The limitation section is intended to give the competent authorities the flexibility to customise the approval to any particular organisation. Ratings shall be mentioned on the approval only when appropriately limited. The table referred to in point 12 specifies the typ es of limitation possible. Whilst maintenance is listed last in each class rating it is acceptable to stress the maintenance task rather than the aircraft or engine type or manufacturer, if this is more appropriate to the organisation (an example could be avionic systems installations and related maintenance). Such mention in the limitation section indicates that the maintenance organisation is approved to carry out maintenance up to and including this particular type/task.

9. When reference is made to series, type and group in the limitation section of class A and B, series means a specific type series such as Cessna 150 or Cessna 172 or Beech 55 series or continental O - 200 series etc; type means a specific type or model such as Cessna 172RG type; any number of series or typ es may be quoted; group means for example Cessna single piston engine aircraft or Lycoming non - supercharged piston engines, etc.

10. When a lengthy capability list is used which could be subject to frequent amendments, then such amendments may be performed in accordance with the indirect approval procedure referred to in points M.A.604(c) and M.B.606(c) .

1 1 . A maintenance organisation which employs only one person to both plan and carry out all maintenance can only hold a limited scope of approval rating. The maximum permissible limits are: CLASS RATING LIMITATION CLASS AIRCRAFT RATING A2 AEROPLANES 5700 PISTON ENGINE 5700 KG AND KG AND BELOW BELOW CLASS AIRCRAFT RATING A3 HELICOPTERS SINGLE PISTON ENGINE 3175 KG AND BELOW CLASS AIRCRAFT RATING A4 AIRCRAFT OTHER NO LIMITATION THAN A1, A2 AND A3 CLASS ENGINES RATING B2 PISTON LESS THAN 450 HP CLASS COMPONENTS OTHER C1 TO C22 AS PER CAPABILITY LIST THAN COMPLETE ENGINES OR APU s .

CLASS SPECIALISED D1 NDT NDT METHOD(S) TO BE SPECIFIED.

It should be noted that such an organisation may be further limited by the competent authority in the terms of approval depending on the capability of the particular organisation.

AMC to Appendix VII — Complex Maintenance Tasks

ED Decision 2015/029/R The sentence ‘suitably approved or authorised welder’ contained in Appendix VII, paragraph 3(c), means that the qualification should meet an officially recognised standard or, otherwise, should be accepted by the competent authority.

Powered by EASA eRules Page 239 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) APPENDICES TO ANNEX I (Part - M)

Appendix VIII — Limited Pilot - owner Maintenance

Regulation (EU) 2020/270 In addition to the requirements laid down in Annex I (Part - M) , the following basic principles are to be complied with before any maintenance task is carried out under the terms of Pilot - owner maintenance: (a) Competence and responsibility 1. The Pilot - owner is always responsible for any maintenance that he performs.

2. Before carrying out any Pilot - owner maintenance tasks, the Pilot - owner must satisfy himself that he is competent to do the task. It is the responsibility of Pilot - owners to familiarize themselves with the standard maintenance practices for their aircraft and with the aircraft maintenance programme. If the Pilot - owner is not competent for the task to be carr ied out, the task cannot be released by the Pilot - owner.

3. The Pilot - owner (or his contracted CAMO or CAO) is responsible for identifying the Pilot - owner tasks according to these basic principles in the maintenance programme and for ensuring that the document is updated in a timely manner.

4. The approval of the maintenance programme has to be carried out in accordance with point M.A.302 .

(b) Tasks The Pilot - owner may carry out simple visual inspections or operations to check for general condition and obvious damage and normal operation of the airframe, engines, systems and components.

Maintenance tasks shall not be carried out by the Pilot - owner when the task: 1. is a critical maintenance task; 2. requires the removal of major components or major assembly and/or; 3. is carried out in compliance with an Airworthiness Directive or an Airworthiness Limitation Item, unless specifically allowed in the AD or the ALI and/or; 4. requires the use of special tools, calibrated tools (except torque wrench and crimping tool) and/or; 5. requires the use of test equipments or special testing (e.g. NDT, system tests or operational checks for avionic equipment) and/or; 6. is composed of any unscheduled special inspections (e.g. heavy landing check) and/or; 7. is effecting systems essential for the IFR operations and/or; 8. is listed in Appendix VII to this Annex or is a component maintenance task in accordance with points M.A.502(a) , (b), (c) or (d) .

The criteria 1 to 8 cannot be overridden by less restrictive instructions issued in accordance with ‘ M.A.302(d) Maintenance Programme’.

Any task described in the aircraft flight manual as preparing the aircraft for flight (Example: assembling the glider wings or pre - flight), is considered to be a pilot task and is not considered a Pilot - owner maintenance task and therefore does not require a Certificate of Release to Service.

(c) Performance of the maintenance Pilot - owner tasks and records Powered by EASA eRules Page 240 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) APPENDICES TO ANNEX I (Part - M) The maintenance data as specified in point M.A.401 must be always available during the conduct of Pilot - owner maintenance and must be complied with. Details of the data referred to in the conduct of Pilot - owner maintenance must be included in the Certificate of Release to Service in accordance with point M.A.803(d) .

The Pilot - owner must inform the approved continuing airworthiness management organisation responsible for the continuing airworthiness of the aircraft (if applicable) not later than 30 days after completion of the Pilot - owner maintenance task in accordance with point M.A.305(a) .

AMC to Appendix VIII — Limited Pilot - o wner Maintenance

ED Decision 2023/013/R 1. The lists here below specify items that can be expected to be completed by an owner who holds a current and valid pilot licence for the aircraft type involved and who meets the competence and responsibility requirements of Appendix VIII to Part - M .

2. The list of tasks may not address in a detailed manner the specific needs of the various aircraft categories. In addition, the development of technology and the nature of the operations undertaken by these categories of aircraft cannot be always adequat ely considered.

3. Therefore, the following lists are considered to be the representative scope of limited Pilot - owner maintenance referred to in M.A.803 and Appendix VIII: − Part A applies to aeroplanes; − Part B applies to rotorcraft; − Part C applies to sailplanes and powered sailplanes; − Part D applies to balloons and airships.

4. Inspection tasks/checks of any periodicity included in an approved maintenance programme can be carried out providing that the specified tasks are included in the generic lists of Parts A to D of this AMC and remain compliant with Part M Appendix VIII b asic principles.

The content of periodic inspections/checks , as well as their periodicity , is not regulated or standardised in an aviation specification. It is the decision of the manufacturer/Type Certificate Holder (TCH) / declarant of a declaration of design compliance to recommend a schedule for each specific type of inspection/check.

For an inspection/check with the same periodicity for different TCHs, the content may differ, and in some cases may be critically safety - related and may need the use of special tools or knowledge and thus would not qualify for Pilot - owner maintenance. Ther efore, the maintenance carried out by the Pilot - owner cannot be generalised to specific inspections such as 50 Hrs, 100 Hrs or 6 Month periodicity.

The Inspections to be carried out are limited to those areas and tasks listed in this AMC to Appendix VIII ; this allows flexibility in the development of the maintenance programme and does not limit the inspection to certain specific periodic inspections. A 50 Hrs/6 Month periodic inspection for a fixed wing aeroplane as well as the one - year inspection on a gl ider may normally be eligible for Pilot - owner maintenance.

1.1.20. Each maintenance task quoted should be defined in a definition section of the programme.

2. Programme basis 2.1. An owner or a CAMO aircraft maintenance programme should normally be based upon the MRB report, where applicable, and the maintenance planning document or Chapter 5 of the maintenance manual from the TC holder or the declarant of a declaration of design compliance (i.e. the manufacturer’s recommended maintenance programme).

The structure and format of these maintenance recommendations may be re - written by the owner or the CAMO to better suit the operation and control of the particular maintenance programme.

2.2. For a new aircraft where no previously approved maintenance programme exists, it will be necessary for the owner or the CAMO to comprehensively appraise the manufacturer’s recommendations (and the MRB report where applicable), together with other airworthi ness information, in order to produce a realistic programme for approval.

2.3. For existing aircraft types it is permissible for the owner or CAMO to make comparisons with maintenance programmes previously approved. It should not be assumed that a programme approved for one owner or the CAMO would automatically be approved for another.

Evaluation should be made of the aircraft/fleet utilisation, landing rate, equipment fit and, in particular, the experience of the owner or the CAMO when assessing an existing programme.

2.4. Critical Design Configuration Control Limitations (CDCCL) If CDCCL have been identified for the aircraft type by the TC/STC holder, maintenance instructions should be developed. CDCCL’s are characterised by features in an aircraft installation or component that should be retained during modification, change, repa ir, or scheduled maintenance for the operational life of the aircraft or applicable component or part.

3. Amendments Amendments (revisions) to the approved maintenance programme should be made by the owner or the CAMO, to reflect changes in the recommendations, modifications, service experience of the TC holder or the declarant of a declaration of design compliance , or as required by the competent authority.

4. Permitted variations to maintenance periods The owner or the CAMO may only vary the periods prescribed by the programme with the approval of the competent authority or through a procedure developed in the maintenance programme and approved by the competent authority.

5. Periodic review of maintenance programme contents 5.1. The owner - or the CAMO - approved maintenance programmes should be subject to periodic review to ensure that they reflect current recommendations issued by the TC holder or the declarant of a declaration of design compliance , revisions to the MRB report if applicable, mandatory requirements and the maintenance needs of the aircraft.

5.2. The owner or the CAMO should review the detailed requirements at least annually for continued validity in the light of operating experience.

6. Reliability Programmes 6.1. Applicability 6.1.1. A reliability programme should be developed in the following cases: (a) the aircraft maintenance programme is based upon MSG - 3 logic; (b) the aircraft maintenance programme includes condition monitored components; (c) the aircraft maintenance programme does not contain overhaul time periods for all significant system components; (d) when specified by the Manufacturer’s maintenance planning document or MRB.

6.1.2. A reliability Programme need not be developed in the following cases: (a) the maintenance programme is based upon the MSG - 1 or 2 logic but only contains hard time or on condition items; (b) the aircraft is not a complex motor - powered aircraft according to Part - M ; (c) the aircraft maintenance programme provides overhaul time periods for all significant system components; (d) Note: for the purpose of this paragraph, a significant system is a system the failure of which could hazard the aircraft safety.

Powered by EASA eRules Page 254 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM TO ANNEX I (Part - M) 6.1.3. Notwithstanding paragraphs 6.1.1 and 6.1.2 above, a CAMO may however, develop its own reliability monitoring programme when it may be deemed beneficial from a maintenance planning point of view.

6.2. Applicability for CAMO/operator of small fleets of aircraft.

6.2.1. For the purpose of this paragraph, a small fleet of aircraft is a fleet of less than 6 aircraft of the same type.

6.2.2. The requirement for a reliability programme is irrespective of the CAMO fleet size.

6.2.3. Complex reliability programmes could be inappropriate for a small fleet. It is recommended that such CAMOs tailor their reliability programmes to suit the size and complexity of operation.

6.2.4. One difficulty with a small fleet of aircraft consists in the amount of available data which can be processed: when this amount is too low, the calculation of alert level is very coarse. Therefore ’alert levels‘ should be used carefully.

6.2.5. A CAMO of a small fleet of aircraft, when establishing a reliability programme, should consider the following: (a) The programme should focus on areas where a sufficient amount of data is likely to be processed.

(b) When the amount of available data is very limited, the CAMO engineering judgement is then a vital element. In the following examples, careful engineering analysis should be exercised before taking decisions: − A ‘0’ rate in the statistical calculation may possibly simply reveal that enough statistical data is missing, rather that there is no potential problem.

− When alert levels are used, a single event may have the figures reach the alert level. Engineering judgement is necessary so as to discriminate an artefact from an actual need for a corrective action.

In making his engineering judgement, a CAMO is encouraged to establish contact and make comparisons with other CAMOs of the same aircraft, where possible and relevant.

Making comparison with data provided by the manufacturer may also be possible.

6.2.6. In order to obtain accurate reliability data, it should be recommended to pool data and analysis with one or more other CAMO(s). Paragraph 6.6 of this paragraph specifies under which conditions it is acceptable that CAMOs share reliability data.

6.2.7. Notwithstanding the above there are cases where the CAMO will be unable to pool data with other CAMO, e.g. at the introduction to service of a new type. In that case the competent authority should impose additional restrictions on the MRB/MPD tasks interva ls (e.g. no variations or only minor evolution are possible, and with the competent authority approval).

6.3. Engineering judgement 6.3.1. Engineering judgement is itself inherent to reliability programmes as no interpretation of data is possible without judgement. In approving the CAMO maintenance and reliability programmes, the competent authority is expected to ensure that the organisation which runs the programme (it may be CAMO, or an Part - 145 organisation under contract) hires sufficiently qualified personnel with appropriate engineering experience and understanding of reliability concept (see AMC M.A.706 ).

Powered by EASA eRules Page 255 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM TO ANNEX I (Part - M) 6.3.2. It follows that failure to provide appropriately qualified personnel for the reliability programme may lead the competent authority to reject the approval of the reliability programme and therefore the aircraft maintenance programme.

6.4. Contracted maintenance 6.4.1. Whereas M.A.302 specifies that, the aircraft maintenance programme - which includes the associated reliability programme - , should be managed and presented by the CAMO to the competent authority, the CAMO may subcontract certain functions to the maintenance organisation under contract, provided this organisation proves to have the appropriate expertise.

6.4.2. These functions are: (a) Developing the aircraft maintenance and reliability programmes, (b) Performing the collection and analysis of the reliability data, (c) Providing reliability reports, and (d) Proposing corrective actions to the CAMO.

6.4.3. Notwithstanding the above decision to implement a corrective action (or the decision to request from the competent authority the approval to implement a corrective action) remains the CAMO prerogative and responsibility. In relation to paragraph 6.4.2(d) a bove, a decision not to implement a corrective action should be justified and documented.

6.4.4. The arrangement between the CAMO and the maintenance organisation should be specified in the maintenance contract (see Appendix XI to AMC M.A.708(c) ) and the relevant CAME, and maintenance organisation procedures.

6.5. Reliability programme In preparing the programme details, account should be taken of this paragraph. All associated procedures should be clearly defined.

6.5.1. Objectives 6.5.1.1. A statement should be included summarising as precisely as possible the prime objectives of the programme. To the minimum it should include the following: (a) to recognise the need for corrective action, (b) to establish what corrective action is needed and, (c) to determine the effectiveness of that action.

6.5.1.2. The extent of the objectives should be directly related to the scope of the programme. Its scope could vary from a component defect monitoring system for a small CAMO, to an integrated maintenance management programme for a big CAMO. The manufacturer’s mai ntenance planning documents may give guidance on the objectives and should be consulted in every case.

6.5.1.3. In case of a MSG - 3 based maintenance programme, the reliability programme should provide a monitor that all MSG - 3 related tasks from the maintenance programme are effective and their periodicity is adequate.

The items controlled by the programme should be stated, e.g. by ATA Chapters. Where some items (e.g. aircraft structure, engines, APU) are controlled by separate programmes, the associated procedures (e.g. individual sampling or life development programmes , constructor’s structure sampling programmes) should be cross referenced in the programme.

6.5.3. Terms and definitions.

The significant terms and definitions applicable to the Programme should be clearly identified. Terms are already defined in MSG - 3, Part - 145 and Part - M .

6.5.4. Information sources and collection.

6.5.4.1. Sources of information should be listed and procedures for the transmission of information from the sources, together with the procedure for collecting and receiving it, should be set out in detail in the CAME or MOE as appropriate.

6.5.4.2. The type of information to be collected should be related to the objectives of the Programme and should be such that it enables both an overall broad based assessment of the information to be made and also allow for assessments to be made as to whether any reaction, both to trends and to individual events, is necessary. The following are examples of the normal prime sources: (a) Pilots Reports.

(b) Technical Logs.

(d) Maintenance Worksheets.

(e) Workshop Reports.

(f) Reports on Functional Checks.

(g) Reports on Special Inspections.

(h) Stores Issues/Reports.

(i) Air Safety Reports.

(j) Reports on Technical Delays and Incidents.

(k) Other sources: ETOPS, RVSM, CAT II/III.

6.5.4.3. In addition to the normal prim ary sources of information, due account should be taken of continuing airworthiness and safety information promulgated under Part 21 or Part 21 Light .

6.5.5. Display of information.

Collected information may be displayed graphically or in a tabular format or a combination of both. The rules governing any separation or discarding of information prior to incorporation into these formats should be stated. The format should be such that t he identification of trends, specific highlights and related events would be readily apparent.

6.5.5.1. The above display of information should include provisions for ‘nil returns’ to aid the examination of the total information.

Powered by EASA eRules Page 257 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM TO ANNEX I (Part - M) 6.5.5.2. Where ‘standards’ or ‘alert levels’ are included in the programme, the display of information should be oriented accordingly.

6.5.6. Examination, analysis and interpretation of the information.

The method employed for examining, analysing and interpreting the programme information should be explained.

6.5.6.1. Examination.

Methods of examination of information may be varied according to the content and quantity of information of individual programmes. These can range from examination of the initial indication of performance variations to formalised detailed procedures at spe cific periods, and the methods should be fully described in the programme documentation.

6.5.6.2. Analysis and Interpretation.

The procedures for analysis and interpretation of information should be such as to enable the performance of the items controlled by the programme to be measured; they should also facilitate recognition, diagnosis and recording of significant problems. The whole process should be such as to enable a critical assessment to be made of the effectiveness of the programme as a total activity.

Such a process may involve: (a) Comparisons of operational reliability with established or allocated standards (in the initial period these could be obtained from in - service experience of similar equipment of aircraft types).

(b) Analysis and interpretation of trends.

(d) Confidence testing of expected and achieved results.

(e) Studies of life - bands and survival characteristics.

(f) Reliability predictions.

(g) Other methods of assessment.

6.5.6.3. The range and depth of engineering analysis and interpretation should be related to the particular programme and to the facilities available. The following, at least, should be taken into account: (a) Flight defects and reductions in operational reliability.

(b) Defects occurring on - line and at main base.

(d) Workshop and overhaul facility findings.

(e) Modification evaluations.

(f) Sampling programmes.

(g) The adequacy of maintenance equipment and publications.

(h) The effectiveness of maintenance procedures.

(i) Staff training.

6.5.6.4. Where the CAMO relies upon contracted maintenance and/or overhaul facilities as an information input to the programme, the arrangements for availability and continuity of such information should be established and details should be included.

6.5.7. Corrective Actions.

6.5.7.1. The procedures and time scales both for implementing corrective actions and for monitoring the effects of corrective actions should be fully described. Corrective actions shall correct any reduction in reliability revealed by the programme and could take the form of: (a) Changes to maintenance, operational procedures or techniques.

(b) Maintenance changes involving inspection frequency and content, function checks, overhaul requirements and time limits, which will require amendment of the scheduled maintenance periods or tasks in the approved maintenance programme. This may include escal ation or de - escalation of tasks, addition, modification or deletion of tasks.

(d) Initiation of modifications.

(e) Special inspections of fleet campaigns.

(f) Spares provisioning.

(g) Staff training.

(h) Manpower and equipment planning.

Note : Some of the above corrective actions may need the competent authority’s approval before implementation.

6.5.7.2. The procedures for effecting changes to the maintenance programme should be described, and the associated documentation should include a planned completion date for each corrective action, where applicable.

6.5.8. Organisational Responsibilities.

The organisational structure and the department responsible for the administration of the programme should be stated. The chains of responsibility for individuals and departments (Engineering, Production, Quality, Operations etc.) in respect of the program me, together with the information and functions of any programme control committees (reliability group), should be defined. Participation of the competent authority should be stated. This information should be contained in the CAME as appropriate.

6.5.9. Presentation of information to the competent authority.

The following information should be submitted to the competent authority for approval as part of the reliability programme: (a) The format and content of routine reports.

(b) The time scales for the production of reports together with their distribution.

These reports should contain sufficient detailed information to enable the competent authority to make its own evaluation where necessary.

6.5.10. Evaluation and review.

Each programme should describe the procedures and individual responsibilities in respect of continuous monitoring of the effectiveness of the programme as a whole. The time periods and the procedures for both routine and non - routine reviews of maintenance control should be detailed (progressive, monthly, quarterly, or annual reviews, procedures following reliability ‘standards’ or ‘alert levels’ being exceeded, etc.).

6.5.10.1. Each Programme should contain procedures for monitoring and, as necessary, revising the reliability ‘standards’ or ‘alert levels’. The organisational responsibilities for monitoring and revising the ‘standards’ should be specified together with associated time scales.

6.5.10.2. Although not exclusive, the following list gives guidance on the criteria to be taken into account during the review.

(a) Utilisation (high/low/seasonal).

(b) Fleet commonality.

(d) Adequacy of data.

(e) Reliability procedure audit.

(g) Operational and maintenance procedures.

6.5.11. Approval of maintenance programme amendment The competent authority may authorise the CAMO to implement in the maintenance programme changes arising from the reliability programme results prior to their formal approval by the authority when satisfied that; (a) the Reliability Programme monitors the content of the Maintenance Programme in a comprehensive manner, and (b) the procedures associated with the functioning of the ‘Reliability Group’ provide the assurance that appropriate control is exercised by the CAMO over the internal validation of such changes.

6.6. Pooling Arrangements.

6.6.1. In some cases, in order that sufficient data may be analysed it may be desirable to ‘pool’ data: i.e. collate data from a number of CAMOs of the same type of aircraft. For the analysis to be valid, the aircraft concerned, mode of operation, and maintenance procedures applied should be substantially the same: variations in utilisation between two CAMOs may, more than anything, fundamentally corrupt the analysis. Although not exhaustive, the following list gives guidance on the primary factors which need to b e taken into account.

(b) Operational Factors, such as: operational environment/utilisation, e.g.

low/high/seasonal, etc./respective fleet size operating rules applicable (e.g.

ETOPS/RVSM/All Weather etc.)/operating procedures/MEL and MEL utilisation.

(c) Maintenance factors, such as: aircraft age maintenance procedures; maintenance standards applicable; lubrication procedures and programme; MPD revision or escalation applied or maintenance programme applicable 6.6.2. Although it may not be necessary for all of the foregoing to be completely common, it is necessary for a substantial amount of commonality to prevail. Decision should be taken by the competent authority on a case by case basis.

6.6.3. In case of a short term lease agreement (less than 6 month) more flexibility against the para 6.6.1 criteria may be granted by the competent authority, so as to allow the owner/ CAMO to operate the aircraft under the same programme during the lease agreement effectivity.

6.6.4. Changes by any one of the CAMO to the above, requires assessment in order that the pooling benefits can be maintained. Where a CAMO wishes to pool data in this way, the approval of the competent authority should be sought prior to any formal agreement bein g signed between CAMOs.

6.6.5. Whereas this paragraph 6.6 is intended to address the pooling of data directly between CAMOs, it is acceptable that the CAMO participates in a reliability programme managed by the aircraft manufacturer, when the competent authority is satisfied that the ma nufacturer manages a reliability programme which complies with the intent of this paragraph.

Ap pendix II to AMC M.A.711(a)(3) — Subcontracting of continuing

airworthiness management tasks

ED Decision 2021/009/R 1. Subcontracted continuing airworthiness management tasks 1.1. To actively control the standards of the subcontracted organisation, the CAMO should employ a person or group of persons who are trained and competent in the disciplines associated with M.A. Subpart G . As such, they are responsible for determining what maintenance is required, when it has to be performed, by whom and to what standard in order to ensure the continuing airworthiness of the aircraft to be operated.

1.2. The CAMO should conduct a pre - subcontract audit to establish that the organisation to be subcontracted can achieve the standards required by M.A. Subpart G in connection with those activities to be subcontracted.

1.3. The CAMO should ensure that the organisation to be subcontracted has sufficient and qualified personnel who are trained and competent in the functions to be sub - contracted. In assessing the adequacy of personnel resources, the CAMO should consider the particular needs of those activities that are to be subcontracted, while taking into account the subcontracted organisations existing commitments.

1.4. To be appropriately approved to subcontract continuing airworthiness management tasks, the CAMO should have procedures for the management control of these arrangements. The continuing airworthiness management exposition should contain relevant procedu res to reflect its control of those arrangements made with the sub - contracted organisation.

1.5. Subcontracted continuing airworthiness management tasks should be addressed in a contract between the CAMO and the subcontracted organisation. The contract should also specify that the subcontracted organisation is responsible for informing the CAMO, that is in turn responsible for notifying the respective competent authority, of any subsequent changes that affect their ability to fulfil the contract.

1.6. The subcontracted organisation should use procedures which set out the manner of fulfilling its responsibilities with regard to the subcontracted activities. Such procedures may be developed by either the subcontracted organisation or the CAMO.

1.7. Where the subcontracted organisation develops its own procedures, they should be compatible with the continuing airworthiness management exposition and the terms of the contract. These should be accepted by the competent authority as extended procedur es of the CAMO and as such should be cross - referenced from the continuing airworthiness management exposition.

One current copy of the subcontracted organisation’s relevant procedures should be kept by the CAMO and should be accessible to the competent aut hority when needed.

Note: Should any conflict arise between the subcontracted organisation’s procedures and those of the CAMO, then the policy and procedures of the continuing airworthiness management exposition will prevail.

1.8. The contract should also specify that the subcontracted organisation’s procedures may only be amended with the agreement of the CAMO. The CAMO should ensure that these amendments are compatible with its continuing airworthiness management exposition a nd comply with M.A.

Subpart G .

The CAMO should nominate the person responsible for continued monitoring and acceptance of the subcontracted organisation’s procedures and their amendments. The controls used to Powered by EASA eRules Page 262 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM TO ANNEX I (Part - M) fulfil this function should be clearly set out in the amendment section of the continuing airworthiness management exposition detailing the level of CAMO involvement.

1.9. Whenever any elements of the continuing airworthiness management tasks are subcontracted, the CAMO personnel should have access to all relevant data in order to fulfil their responsibilities.

Note: The CAMO retains the authority to override, whenever necessary for the continuing airworthiness of their aircraft, any recommendation of the subcontracted organisation.

1.10. The CAMO should ensure that the subcontracted organisation continues to have qualified technical expertise and sufficient resources to perform the sub - contracted tasks while complying with the relevant procedures. Failure to do so may invalidate the CAMO approval.

1.11. The contract should provide for competent authority monitoring.

1.12. The contract should address the respective responsibilities to ensure that any findings arising from the competent authority monitoring will be closed to the satisfaction of the competent authority.

2. Accomplishment This paragraph describes the topics which may be applicable to such subcontracting arrangements.

2.1. Scope of work The type of aircraft and their registrations, engine types and/or components subject to the continuing airworthiness management tasks contract should be specified.

2.2. Maintenance programme development and amendment The CAMO may subcontract the preparation of the draft maintenance programme and any subsequent amendments. However, the CAMO remains responsible for assessing that the draft proposals meet its needs and for obtaining competent authority approval; the relev ant procedures should specify these responsibilities. The contract should also stipulate that any data necessary to substantiate the approval of the initial programme or an amendment to this programme should be provided for CAMO agreement and/or competent authority upon request.

2.3 . Maintenance programme effectiveness and reliability The CAMO should have a system in place to monitor and assess the effectiveness of the maintenance programme based on maintenance and operational experience. The collection of data and initial assessment may be made by the subcontracted organisation; the required actions are to be endorsed by the CAMO.

Where reliability monitoring is used to establish the effectiveness of the maintenance programme, this may be provided by the subcontracted organisation and should be specified in the relevant procedures. Reference should be made to the approved maintenanc e and reliability programme. Participation of the CAMO’s personnel in reliability meetings with the subcontracted organisation should also be specified.

When providing reliability data, the subcontracted organisation is limited to working with primary data/documents provided by the CAMO or data provided by the CAMO’s contracted maintenance organisation(s) from which the reports are derived. The pooling of reliability data is permitted if it is acceptable to the competent authority.

Powered by EASA eRules Page 263 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM TO ANNEX I (Part - M) 2.4. Permitted variations to the maintenance programme The reasons and justification for any proposed variation to scheduled maintenance may be prepared by the subcontracted organisation. Acceptance of the proposed variation should be granted by the CAMO. The means by which the CAMO acceptance is given should be specified in the relevant procedures. When outside the limits set out in the maintenance programme, the CAMO is required to obtain approval by the competent authority.

2.5. Scheduled maintenance Where the subcontracted organisation plans and defines maintenance checks or inspections in accordance with the approved maintenance programme, the required liaison with the CAMO, including feedback, should be defined.

The planning control and documentation should be specified in the appropriate supporting procedures. These procedures should typically set out the CAMO’s level of involvement in each type of check. This will normally involve the CAMO assessing and agreeing to a work specification on a case - by - case basis for base maintenance checks. For routine line maintenance checks, this may be controlled on a day - to - day basis by the subcontracted organisation subject to appropriate liaison and CAMO controls to ensure tim ely compliance. This may typically include but is not necessarily limited to: − applicable work package, including job cards; − scheduled component removal list; − ADs to be incorporated; − modifications to be incorporated.

The associated procedures should ensure that the CAMO is informed in a timely manner on the accomplishment of such tasks.

2.6. Quality monitoring The CAMO’s quality system should monitor the adequacy of the subcontracted continuing airworthiness management task performance for compliance with the contract and with M.A.

Subpart G . The terms of the contract should therefore include a provision allowing the CAMO to perform a quality surveillance (including audits) of the subcontracted organisation. The aim of the surveillance is primarily to investigate and judge the effectiveness o f those subcontracted activities and thereby to ensure compliance with M.A Subpart G and the contract. Audit reports may be subject to review when requested by the competent authority.

2.7. Access to the competent authority The contract should specify that the subcontracted organisation should always grant access to the competent authority.

2.8. Maintenance data The maintenance data used for the purpose of the contract should be specified, together with those responsible for providing such documentation and the competent authority responsible for the acceptance/approval of such data, when applicable. The CAMO shou ld ensure that such data, including revisions, is readily available to the CAMO personnel and to those in the subcontracted organisation who may be required to assess such data. The CAMO should establish a ‘fast track’ means to ensure that urgent data is t ransmitted to the subcontractor in a timely manner. Maintenance data is defined in M.A.401(b) or ML.A.401(b) .

2.9. Airworthiness directives (ADs) Powered by EASA eRules Page 264 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM TO ANNEX I (Part - M) While the various aspects of AD assessment, planning and follow - up may be accomplished by the subcontracted organisation, AD embodiment is performed by a maintenance organisation.

The CAMO is responsible for ensuring timely embodiment of the applicable ADs and is to be provided with notification of compliance. It, therefore, follows that the CAMO should have clear policies and procedures on AD embodiment supported by defined procedures which will ensure that the CAMO agrees to the proposed means of complian ce.

The relevant procedures should specify: − what information (e.g. AD publications, continuing airworthiness records, flight hours/cycles, etc.) the subcontracted organisation needs from the CAMO; − what information (e.g. AD planning listing, detailed engineering order, etc.) the CAMO needs from the subcontracted organisation in order to ensure timely compliance with the ADs.

To fulfil the above responsibility, the CAMO should ensure that it receives current mandatory continued airworthiness information for the aircraft and equipment it is managing.

2.10. Service bulletin (SB) modifications The subcontracted organisation may be required to review and make recommendations on the embodiment of an SB and other associated non - manda tory material based on a clear policy established by the CAMO. This should be specified in the contract.

2.11. Mandatory life limitation or scheduled maintenance controls and component control/removal forecast Where the subcontracted organisation performs planning activities, it should be specified that the organisation should receive the current flight cycles, flight hours, landings and/or calendar controlled details, as applicable, at a frequency to be specifi ed in the contract. The frequency should be such that it allows the organisation to properly perform the subcontracted planning functions. It, therefore, follows that there will need to be adequate liaison be tween the CAMO, the contracted maintenance organ isation(s) and the subcontracted organisation. Additionally, the contract should specify how the CAMO will be in possession of all current flight cycles, flight hours, etc., so that it may assure the timely accomplishment of the required maintenance.

2.12. Engine health monitoring If the CAMO subcontracts the on - wing engine health monitoring, the subcontracted organisation should receive all the relevant information to perform this task, including any parameter reading deemed necessary to be supplied by the CAMO for this control. Th e contract should also specify what kind of feedback information (such as engine limitation, appropriate technical advice, etc.) the organisation should provide to the CAMO.

2.13. Defect control Where the CAMO has subcontracted the day - to - day control of technical log deferred defects, this should be specified in the contract and should be adequately described in the appropriate procedures. The operator’s MEL/CDL provides the basis for establishing which defects may be deferred and the associated limits. The procedures should also define the responsibilities and actions to be taken for defects such as AOG situations, repetitive defects, and damage beyond the type certificate holder’s limits.

For all other defects identified during maintenance, the information should be brought to the attention of the CAMO which, depending upon the procedural authority granted by the competent authority, may determine that some defects can be deferred. Therefor e, adequate Powered by EASA eRules Page 265 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM TO ANNEX I (Part - M) liaison between the CAMO, its subcontracted organisation and contracted maintenance organisation should be ensured.

The subcontracted organisation should make a positive assessment of potential deferred defects and consider the potential hazards arising from the cumulative effect of any combination of defects. The subcontracted organisations should liaise with the CAMO to get its agreement following this assessment.

Deferment of MEL/CDL allowable defects can be accomplished by a contracted maintenance organisation in compliance with the relevant technical log procedures, subject to the acceptance by the aircraft commander.

2.14. Mandatory occurrence reporting All incidents and occurrences that meet the reporting criteria defined in Part - M and Part - 145 should be reported as required by the respective requirements. The CAMO should ensure that adequate liaison exists with the subcontracted organisation and the maintenance organisation.

2.15. Continuing airworthiness records They may be maintained and kept by the subcontracted organisation on behalf of the CAMO, which remains the owner of these documents. However, the CAMO should be provided with the current status of AD compliance and life - limited parts and time - controlled components in accordance with the agreed procedures. The CAMO should also be granted unrestricted and timely access to the original records as and when needed. Online access to the appropriate information systems is acceptable.

The record - keeping requirements of Part - M should be met. Access to the records by duly authorised members of the competent authority should be granted upon request.

2.16. Maintenance check flight (MCF) procedures MCFs are performed under the control of the operator in coordination with the CAMO. MCF requirements from the subcontracted organisation or contracted maintenance organisation should be agreed by the operator/CAMO.

2.17. Communication between the CAMO and the subcontracted organisation 2.17.1. In order to fulfil its airworthiness responsibility, the CAMO needs to receive all the relevant reports and relevant maintenance data. The contract should specify what information should be provided and when.

2.17.2. Meetings provide one important cornerstone whereby the CAMO can fulfil part of its responsibility for ensuring the airworthiness of the operated aircraft. They should be used to establish good communication between the CAMO, the subcontracted organisation and the contracted maintenance organisation. The terms of the contract should include, whenever appropriate, the provision for a certain number of meetings to be held between the involved parties. Details of the types of liaison meetings and associ ated terms of reference of each meeting should be documented. The meetings may include but are not limited to all or a combination of: (a) Contract review Before the contract is enforced, it is very important that the technical personnel of both parties, that are involved in the fulfilment of the contract, meet in order to be sure that every point leads to a common understanding of the duties of both parties .

(c) Technical meeting Scheduled meetings should be organised in order to review on a regular basis and agree on actions on technical matters such as ADs, SBs, future modifications, major defects found during shop visit, reliability, etc.

(d) Quality meeting Quality meetings should be organised in order to examine matters raised by the CAMO’s quality surveillance and the competent authority’s monitoring activity and to agree on necessary corrective actions.

(e) Reliability meeting When a reliability programme exists, the contract should specify the involvement of the CAMO and of the subcontracted organisation in that programme, including their participation in reliability meetings. Provision to enable competent authority participati on in the periodical reliability meetings should also be made.

DISTRIBUTION LIST (The document should include a distribution list to ensure proper distribution of the manual and to demonstrate to the competent authority that all personnel involved in continuing airworthiness activities have access to the relevant information. This does not mean that all personnel have to receive a manual, but that a reasonable amount of manuals is distributed within the organisation(s) so that personnel concerned have quick and easy access to the manual.

Accordingly, the continuing airworthiness management exposition should be distributed to: − the operator’s or the organisation’s management personnel and to any person at a lower level as necessary; and − the Part - 145 or M.A. Subpart F contracted maintenance organisation(s); and − the competent authority.)

Any amendment to the statement should not alter its intent.)

‘This exposition defines the organisation and procedures upon which the M.A. Subpart G approval of Joe Bloggs under Part - M is based.

These procedures are approved by the undersigned and must be complied with, as applicable, in order to ensure that all continuing airworthiness activities, including maintenance of aircraft managed by Joe Bloggs, are carried out on time to an approved stan dard.

It is accepted that these procedures do not override the necessity of complying with any new or amended regulation published by the Agency or the competent authority from time to time where these new or amended regulations are in conflict with these proced ures.

The competent authority will approve this organisation whilst it is satisfied that the procedures are followed. It is understood that the competent authority reserves the right to suspend, limit or revoke the M.A. Subpart G continuing airworthiness managem ent approval of the organisation, as applicable, if the competent authority has evidence that the procedures are not followed and the standards not upheld.

In the case of air carriers licensed in accordance with Regulation (EC) No 1008/2008, suspension or revocation of the approval of the M.A. Subpart G continuing airworthiness management organisation would invalidate the AOC.’ 0.2 General Information a) Brief description of the organisation (This paragraph should describe broadly how the whole organisation (i.e. including the whole operator in the case of air carriers licensed in accordance with Regulation (EC) No 1008/2008 or the whole organisation when other approvals are held) is organised under the management of the accountable manager, and should refer to the organisation charts of paragraph 0.4.)

b) Relationship with other organisations (This paragraph may not be applicable to every organisation.)

(1) Subsidiaries/mother company (For clarity purposes, where the organisation belongs to a group, this paragraph should explain the specific relationship the organisation may have with other members of that group, e.g. links between Joe Bloggs Airlines, Joe Bloggs Finance, Joe Bloggs Lea sing, Joe Bloggs Maintenance, etc.)

(2) Consortia (Where the organisation belongs to a consortium, it should be indicated here. The other members of the consortium should be specified, as well as the scope of organisation of the consortium (e.g. operations, maintenance, design (modifications and repairs), production etc.). The reason for specifying this is that consortium maintenance may be controlled through specific contracts and through consortium’s policy and/or procedures manuals that might unintentionally override the maintenance contracts. In additi on, in respect of international consortia, the Powered by EASA eRules Page 298 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM TO ANNEX I (Part - M) respective competent authorities should be consulted and their agreement to the arrangement should be clearly stated. This paragraph should then make reference to any consortium’s continuing airworthiness related manual or procedure and to any competent au thority agreement that would apply.)

c) Scope of work — Aircraft managed (This paragraph should specify the scope of the work for which the CAMO is approved.

This paragraph may include aircraft type/series, aircraft registrations, owner/operator, contract references, etc. The following is given as an example.)

Aircraft Date Aircraft maintenance Aircraft Owner/ CAMO type/ included in programme or registration(s) operator contract series the scope of ‘generic/baseline’ reference work maintenance programme For air carriers licensed in accordance with Regulation (EC) No 1008/2008, this paragraph can make reference to the operations specifications or operations manual where the aircraft registrations are listed.

(Depending on the number of aircraft, this paragraph may be updated as follows: 1) the paragraph is revised each time an aircraft is removed from or added in the list; 2) the paragraph is revised each time a type of aircraft or a significant number of aircraft is removed from or added to the list; in that case, the paragraph should explain where the current list of aircraft managed is available for consultation.)

d) Type of operation (This paragraph should give broad information on the type of operations such as: commercial air transport operations, (commercial) specialised operations, training organisation, NCC, NCO, long haul/short haul/regional, scheduled/charter, regions/countries/ continents flown, etc.)

0.3 Management personnel a) Accountable manager (This paragraph should address the duties and responsibilities of the accountable manager as regards M.A. Subpart G approvals and should demonstrate that he/she has corporate authority for ensuring that all continuing airworthiness activities can be financed and carried out to the required standard.)

b) Nominated postholder for continuing airworthiness referred to in M.A.706(d) (This paragraph should: − emphasise that the nominated postholder for continuing airworthiness is responsible to ensure that all maintenance is carried out on time and to an approved standard; and − describe the extent of his/her authority as regards his/her Part - M responsibility for continuing airworthiness. ) Powered by EASA eRules Page 299 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM TO ANNEX I (Part - M) c) Continuing airworthiness coordination (This paragraph should list in sufficient detail the job functions that constitute the ‘group of persons’ as required by M.A.706(c) so as to show that all the continuing airworthiness responsibilities as described in Part - M are covered by the persons that constitute that group. In the case of small operators where the ‘nominated postholder’ for continuing airworthiness constitutes hims elf/herself the ‘group of persons’, this paragraph may be merged with the previous one.)

d) Duties and responsibilities (This paragraph should further elaborate the duties and responsibilities of all the nominated persons and of any other management personnel.)

e) Manpower resources and training policy (1) Manpower resources (This paragraph should give broad figures to show that the number of people assigned to the performance of the approved continuing airworthiness activity is adequate. It is not necessary to give the detailed number of employees of the whole company, but on ly the number of those involved in continuing airworthiness. This could be presented as follows:) As of 28 November 2003, the number of employees assigned to the performance of the continuing airworthiness management system is the following: Full - time Part - time in equivalent full - time Quality monitoring AA aa = AA’ Continuing airworthiness management BB bb = BB’ (Detailed information about the BB1 bb1 = BB1’ management of group of persons) BB2 bb2 = BB2’ Other... CC cc =CC’ Total TT tt = TT’ Total man - hours TT + TT’ (Note: According to the size and complexity of the organisation, this table may be further developed or simplified.)

(2) Training policy (This paragraph should show that the training and qualification standards for the personnel mentioned above are consistent with the size and complexity of the organisation. It should also explain how the need for recurrent training is assessed and how training recording and follow - up is performed.)

Joe Bloggs will not incorporate such changes until they have been assessed and approved by the competent authority.)

0.6 Exposition amendment procedure (This paragraph should explain who is responsible for the amendment of the exposition and its submission to the competent authority for approval. This may include, if agreed by the competent authority, the possibility for the approved organisation to appro ve internally minor amendments that have no impact on the approval held. The paragraph should then specify what types of amendments are considered minor and major, and what the approval procedures for both cases are.)

PART 1 — CONTINUING AIRWORTHINESS MANAGEMENT PROCEDURES 1.1 Aircraft technical log utilisation and MEL application or 1.1 Aircraft continuing airworthiness record system utilisation a) Aircraft technical log and/or continuing airworthiness record system (1) General (It may be useful to recall, in this introductory paragraph, the purpose of the aircraft technical log system and/or the continuing airworthiness record system, with special attention to the options of M.A.305 and M.A.306 .

For that purpose, the paragraphs M.A.305 and M.A.306 may be quoted or further explained.)

(2) Instructions for use (This paragraph should provide instructions for using the aircraft technical log and/or continuing airworthiness record system. It should emphasise the respective responsibilities of the maintenance personnel and operating crew. Samples of the technical lo g and/or continuing airworthiness record system should be included in Part 5 ‘Appendices’ in order to provide enough detailed instructions.)

(3) Aircraft technical log approval (This paragraph should explain who is responsible for submitting the aircraft technical log, and any subsequent amendment thereto, to the competent authority for approval and what is the procedure to be followed.)

b) MEL application (The MEL is a document not controlled by the CAMO and the decision of whether accepting or not the operation with a defect deferred in accordance with the MEL is normally the responsibility of the operating crew. This paragraph should explain in sufficient detail the MEL application procedure, because the MEL is a tool that the personnel involved in continuing airworthiness and maintenance have to be familiar with in order to ensure proper and efficient communication with the crew in case of a defect rectif ication to be deferred.)

(This paragraph does not apply to those types of aircraft that do not have an MEL.)

The information could be extracted from the aircraft flight manual.)

(2) MEL categories (Where an owner/operator uses a classification system placing a time constraint on the rectification of defects, it should be explained here what are the general principles of such a system. It is essential for the personnel involved in continuing airworth iness and maintenance to be familiar with it for the management of the MEL’s deferred defect rectification.)

(3) Application (This paragraph should explain how the continuing airworthiness and maintenance personnel make the flight crew aware of an MEL limitation. This should refer to the technical log procedures.)

(4) Acceptance by the crew (This paragraph should explain how the crew notifies their acceptance or non - acceptance of the MEL deferment in the technical log.)

(5) Management of the MEL time limits (Once a technical limitation is accepted by the crew, the defect must be rectified within the time limit specified in the MEL. There should be a system to ensure that the defect will actually be rectified before that time limit. This system could be the ai rcraft technical log for those (small) operators that use it as a planning document, or a specific follow - up system where control of the maintenance time limit is ensured by other means such as data processed planning systems.)

(6) MEL time limitation overrun (The competent authority may allow the owner/operator to overrun the MEL time limitation under specific conditions. Where applicable, this paragraph should describe the specific duties and responsibilities with regard to controlling these extensions.)

1.2 Aircraft maintenance programme — development and amendment a) General (This introductory paragraph should recall that the purpose of a maintenance programme is to provide maintenance planning instructions necessary for the safe operation of the aircraft.)

b) Content (This paragraph should explain what is (are) the format(s) of the aircraft maintenance programme(s). Appendix I to AMC M.A.302(a) and M.B.301(d) should be used as a guideline to develop this paragraph.)

c) Development (1) Sources (This paragraph should explain what are the sources (MRB, MPD, maintenance manual, etc.) used for the development of an aircraft maintenance programme.)

Powered by EASA eRules Page 303 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM TO ANNEX I (Part - M) (2) Responsibilities (This paragraph should explain who is responsible for the development of an aircraft maintenance programme.)

(3) Manual amendments (This paragraph should demonstrate that there is a system for ensuring the continuing validity of the aircraft maintenance programme. Particularly, it should show how any relevant information is used to update the aircraft maintenance programme. This shoul d include, as applicable, MRB report revisions, consequences of modifications, manufacturer and competent authority recommendations, in - service experience, and reliability reports.)

(4) Acceptance by the authority (This paragraph should explain who is responsible for the submission of the maintenance programme to the competent authority and what the procedure to follow is. This should in particular address the issue of the approval for variation to maintenance perio ds either by the competent authority or by a procedure in the maintenance programme for the organisation to approve internally certain changes.)

1.3 Time and continuing airworthiness records, responsibilities, retention and access a) Hours and cycles recording (The recording of flight hours and cycles is essential for the planning of maintenance tasks.

This paragraph should explain how the continuing airworthiness management organisation has access to the current flight hours and cycles information and how it is processed through the organisation .)

b) Records (This paragraph should give in detail the type of company documents that are required to be recorded and what are the recording period requirements for each of them. This can be provided by a table or series of tables that would include the following: − family of document (if necessary), − name of document, − retention period, − responsible person for retention, − place of retention.)

c) Preservation of records (This paragraph should set out the means provided to protect the records from fire, flood, etc., as well as the specific procedures in place to ensure that the records will not been altered during the retention period (especially computer records).)

d) Transfer of continuing airworthiness records (This paragraph should set out the procedure for the transfer of records in case of purchase/lease - in, sale/lease - out and transfer of an aircraft to another organisation. In particular, it should specify which records have to be transferred and who is resp onsible for the coordination (if necessary) of the transfer.)

This paragraph may, for instance, include the following subparagraphs:) a) Airworthiness directive information (This paragraph should explain what the AD information sources are and who receives them in the company. Where available, multiple sources (e.g. Agency + competent authority + manufacturer or association) may be useful.)

b) Airworthiness directive decision (This paragraph should explain how and by whom the AD information is analysed and what kind of information is provided to the contracted maintenance organisations in order to plan and perform the airworthiness directive. This should include as necessary a specific procedure for the management of emergency airworthiness directives.)

c) Airworthiness directive control (This paragraph should specify how the organisation manages to ensure that all the applicable airworthiness directives are accomplished and that they are accomplished on time. This should include a closed - loop system that allows verifying that for each new or revised airworthiness directive and for each aircraft: − the AD is not applicable, or − if the AD is applicable: − the AD is not yet accomplished but the time limit is not overdue, − the AD is accomplished and any repetitive inspection is identified and performed.

This may be a continuous process or may be based on scheduled reviews.)

1.5 Analysis of the effectiveness of the maintenance programme (This paragraph should show what tools are used in order to analyse the efficiency of the maintenance programme, such as: − pilot reports (PIREPS), − air turnbacks, − spare consumption, − repetitive technical occurrence and defect, − technical delays analysis (through statistics, if relevant), − technical incidents analysis (through statistics, if relevant), − etc.

This paragraph should also indicate by whom and how this data is analysed, what is the decision process to take action and what kind of action could be taken. This may include: − amendment of the maintenance programme, − amendment of maintenance or operational procedures, Powered by EASA eRules Page 305 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM TO ANNEX I (Part - M) − etc.)

1.6 Non - mandatory modification embodiment policy (This paragraph should specify how non - mandatory modification information is processed through the organisation, who is responsible for its assessment against the operator’s/owner’s own needs and operational experience, what are the main criteria for decis ion and who takes the decision of implementing (or not) a non - mandatory modification.)

1.7 Major repair and modification standards (This paragraph should set out a procedure for the assessment of the approval status of any major repair or modification before embodiment. This will include the assessment of the need of an Agency or design organisation approval. It should also identify the type of approval required, and the procedure to follow to have a repair or modificati on approved by the Agency or design organisation.)

1.8 Defect reports a) Analysis (This paragraph should explain how the defect reports provided by the contracted maintenance organisations are processed by the continuing airworthiness management organisation. Analysis should be conducted in order to give elements to activities such as m aintenance programme evolution and non - mandatory modification policy.)

b) Liaison with manufacturers and regulatory authorities (Where a defect report shows that such defect is likely to occur to other aircraft, a liaison should be established with the manufacturer and the certification competent authority so that they may take all the necessary action.)

c) Deferred defect policy (Defects such as cracks and structural defects are not addressed in the MEL and CDL.

However, it may be necessary in certain cases to defer the rectification of a defect. This paragraph should establish the procedure to be followed in order to be sure that the deferment of any defect will not lead to any safety concern. This will include appropriate liaison with the manufacturer.)

1.9 Engineering activity (Where applicable, this paragraph should present the scope of the organisation’s engineering activity in terms of approval of modifications and repairs. It should set out a procedure for developing and submitting a modification/repair design for approval t o the Agency and include reference to the supporting documentation and forms used. It should identify the person in charge of accepting the design before submission to the Agency or the competent authority.

Where the organisation has a DOA capability under Part - 21, it should be indicated here and the related manuals should be referred too.)

1.10 Reliability programmes (This paragraph should explain appropriately the management of a reliability programme. It should at least address the following: − extent and scope of the reliability programme, − specific organisational structure, duties and responsibilities, Powered by EASA eRules Page 306 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM TO ANNEX I (Part - M) − establishment of reliability data, − analysis of reliability data, − corrective action system (maintenance programme amendment), − scheduled reviews (reliability meetings and when the participation of the competent authority is needed.)

(This paragraph may, where necessary, be subdivided as follows:) a) Airframe b) Propulsion c) Component 1.11 Pre - flight inspections (This paragraph should show how the scope and definition of pre - flight inspection, that is usually performed by the operating crew, are kept consistent with the scope of the maintenance performed by the contracted maintenance organisations. It should show how the evolution of the content of the pre - flight inspection and of the maintenance programme are concurrent.)

(The following paragraphs are self - explanatory. Although these activities are normally not performed by continuing airworthiness personnel, these paragraphs have been placed here in order to ensure that the related procedures are consistent with the contin uing airworthiness activity procedures.)

a) Preparation of aircraft for flight b) Subcontracted ground - handling function c) Security of cargo and baggage loading d) Control of refueling, quantity/quality e) Control of snow, ice, residues from de - icing or anti - icing operations, dust and sand contamination to an approved standard 1.12 Aircraft weighing (This paragraph should state the cases where an aircraft has to be weighed (for instance, after a major modification because of weight and balance operational requirements, etc.), who performs it, according to which procedure, who calculates the new weight and balance, and how the result is processed in the organisation.)

1.13 Maintenance check flight (MCF) procedures (The criteria for performing an MCF are normally included in the aircraft maintenance programme or derived by the scenarios described in GM M.A.301(i) . This paragraph should explain how the MCF procedure is established in order to meet its intended purpose (for instance, after a heavy maintenance check, after engine or flight control removal installation, etc.), and the release procedures to authorise s uch an MCF.)

It should include as a minimum the monitoring compliance with Part - M and with any additional standards specified by t he organisation.)

b) Continuing airworthiness quality plan (This paragraph should show how the quality plan is established. The quality plan will consist of a quality audit and sampling schedule that should cover all the areas specific to Part - M in a definite period of time. However, the scheduling process should also be dynamic and allow for special evaluations when trends or concerns are identified. In case of subcontracting, this paragraph should also address the planning of the auditing of subcontractors at the same frequency with the rest of the organisation.)

c) Continuing airworthiness quality audit procedure (Quality audit is a key element of the quality system. Therefore, the quality audit procedure should be sufficiently detailed to address all the steps of an audit from preparation to conclusion; it should show the audit report format (e.g. by reference to paragraph 5.1 ‘Sample of document’), and should explain the rules for the distribution of audit reports in the organisation (e.g. involvement of the quality manager, accountable manager, nominated postholder, etc.).)

d) Continuing airworthiness quality audit remedial action procedure (This paragraph should explain what system is put in place in order to ensure that the corrective actions are implemented on time and that the result of the corrective actions meets the intended purpose. For instance, where this system consists in periodic al corrective actions review, instructions should be given on how such reviews should be conducted and what should be evaluated.)

2.2 Monitoring of continuing airworthiness management activities (This paragraph should set out a procedure to periodically review the activities of the continuing airworthiness management personnel and how they fulfil their responsibilities, as defined in Part 0.)

2.3 Monitoring of the effectiveness of the maintenance programme(s) (This paragraph should set out a procedure to periodically review that the effectiveness of the maintenance programme(s) is actually analysed as defined in Part 1.)

2.4 Monitoring that all maintenance is carried out by an appropriate maintenance organisation (This paragraph should set out a procedure to periodically review that the approval of the contracted maintenance organisations is relevant for the maintenance of the operator’s fleet.

This may include feedback information from any contracted organisation on any actual or contemplated amendment in order to ensure that the maintenance system remains valid and to anticipate any necessary change in the maintenance agreements.

This may include a procedure to ensure th at the system allows all the personnel involved in the contract (including the contractors and their subcontractors) to familiarise themselves with its terms and that, for any contract amendment, relevant information is distributed in the organisation and to the contractor.)

2.6 Quality audit personnel (This paragraph should establish the required training and qualification standards for auditors.

Where persons act as part - time auditors, it should be emphasised that they must not be directly involved in the activity they are auditing.)

PART 3 — CONTRACTED MAINTENANCE 3.1 Procedures for contracted maintenance a) Procedures for the development of maintenance contracts (This paragraph should explain the procedures that the organisation follows to develop the maintenance contract. The CAMO processes to implement the different elements described in Appendix XI to AMC M.A.708(c) should be explained. In particular, it should cover responsibilities, tasks and interaction with the maintenance organisation and with the owner/operator.

This paragraph should also describe, when necessary, the use of work orders for unscheduled line maintenance and component maintenance as per M.A.708(d) . The organisation may develop a work order template to ensure that the applicable elements of Appendix XI to AMC M.A.708(c) are considered. Such a template should be included in Part 5.1.)

b) Maintenance contractor selection procedure (This paragraph should explain how a maintenance contractor is selected by the CAMO.

Selection should not be limited to the verification that the contractor is appropriately approved for the specific type of aircraft, but also that the contractor has the i ndustrial capacity to undertake the required maintenance. The selection procedure should preferably include a contract review process in order to ensure that: − the contract is comprehensive and that it has no gaps or unclear areas, − everyone involved in the contract (both at the continuing airworthiness management organisation and at the maintenance contractor) agrees with the terms of the contract and fully understands their responsibilities.

− that functional responsibilities of all parties are clearly identified.

4.4 Additional procedures for recommendations to competent authorities for the import of aircraft (This paragraph should describe the additional tasks regarding the recommendation for the issue of an airworthiness review certificate in the case of import of aircraft. This should include: communication with the competent authority of registry, additiona l items to be reviewed during the airworthiness review of the aircraft, specification of maintenance required to be carried out, etc.)

4.5 Recommendations to competent authorities for the issue of airworthiness review certificates (ARCs) (This paragraph should stipulate the communication procedures with the competent authorities in case of a recommendation for the issue of an airworthiness review certificate. In addition, the content of the recommendation should be described.)

4.6 Issue of airworthiness review certificates (ARCs) (This paragraph should set out the procedure for the issue of ARCs. It should address record - keeping, distribution of ARC copies, etc. The procedure should ensure that an ARC is issued only after an airworthiness review has been properly carried out.)

Appendix VIII to AMC M.A.616 — Organisational Review

ED Decision 2020/002/R This is only applicable to organisations with less than 10 maintenance staff members. For larger organisations, the principles and practices of an independent quality system should be used.

Depending on the complexity of the small organisation (number and type of aircraft, number of different fleets, subcontracting of specialised services, etc.), the organisational review system may vary from a system using the principles and practices of a q uality system (except for the requirement of independence) to a simplified system adapted to the low complexity of the organisation and the aircraft managed.

As a core minimum, the organisational review system should have the following features, which should be described in the Maintenance Organisation Manual (MOM): a. Identification of the person responsible for the organisational review programme.

By default, this person should be the accountable manager, unless he delegates this responsibility to (one of) the M.A.606(b) person(s).

b. Identification and qualification criteria for the person(s) responsible for performing the organisational reviews.

These persons should have a thorough knowledge of the regulations and of the maintenance organisation procedures. They should also have knowledge of audits, acquired through training or through experience (preferably as an auditor, but also possibly becaus e they actively participated in several audits conducted by the competent authority).

c. Elaboration of the organisational review programme: − Checklist(s) covering all items necessary to be satisfied that the organisation delivers a safe product and complies with the regulation. All procedures described in the MOM should be addressed.

− A schedule for the accomplishment of the checklist items. Each item should be checked at least every 12 months. The organisation may choose to conduct one full review annually or to conduct several partial reviews.

d. Performance of organisational reviews Each checklist item should be answered using an appropriate combination of: − review of records, documentation, etc; − sample check of aircraft under contract or being maintained under a work order; − interview of personnel involved; − review of discrepancies and difficulty internal reports (e.g. notified difficulties in using current procedures and tools, systematic deviations from procedures, etc.); − review of complaints filed by customers after delivery.

e. Management of findings and occurrence reports.

− All findings should be recorded and notified to the affected persons.

− All level 1 findings, in the sense of M.A.619(a) , should be immediately notified to the competent authority and all necessary actions on aircraft in service should be immediately taken.

Powered by EASA eRules Page 324 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM TO ANNEX I (Part - M) − All occurrence reports should be reviewed with the aim for continuous improvement of the system by identifying possible corrective and preventive actions. This should be done in order to find prior indicators (e.g., notified difficulties in using current p rocedures and tools, systematic deviations from procedures, unsafe behaviours, etc.), and dismissed alerts that, had they been recognised and appropriately managed before the event, could have resulted in the undesired event being prevented.

− Corrective and preventive actions should be approved by the person responsible for the organisational review programme and implemented within a specified time frame.

− Once the person responsible for the organisational review programme is satisfied that the corrective action is effective, closure of the finding should be recorded along with a summary of the corrective action.

− The accountable manager should be notified of all significant findings and, on a regular basis, of the global results of the organisational review programme.

Following is a typical example of a simplified organisational review checklist, to be adapted as necessary to cover the MOM procedures: 1 – Scope of work Check that: − All aircraft and components under maintenance or under contract are covered in EASA Form 3.

− The scope of work in the MOM does not disagree with EASA Form 3.

− No work has been performed outside the scope of EASA Form 3 and the MOM.

2 – Maintenance data − Check that maintenance data to cover the aircraft in the scope of work of the MOM are present and up - to - date.

− Check that no change has been made to the maintenance data from the TC holder without being notified.

3 – Equipment and Tools − Check the equipment and tools against the lists in the MOM and check if still appropriate to the TC holder’s instructions.

− Check tools for proper calibration (sample check).

4 – Stores − Do the stores meet the criteria in the procedures of the MOM?

− Check by sampling some items in the store for presence of proper documentation and any overdue items.

5 – Certification of maintenance and air worthiness review − Has maintenance on products and components been properly certified?

− Have implementation of modifications/repairs been carried out with appropriate approval of such modifications/repairs (sample check)?

− Have airworthiness reviews been properly performed and the airworthiness review certificate properly been issued?

− When a contract has been signed with an owner/operator, has the obligations of the contracts been respected on each side?

7 – Personnel − Check that the current accountable manager and other nominated persons are correctly identified in the approved MOM.

− If the number of personnel has decreased or if the activity has increased, check that the staff are still adequate to ensure a safe product.

− Check that the qualification of all new personnel (or personnel with new functions) has been appropriately assessed.

− Check that the staff have been trained, as necessary, to cover changes in: − regulations, − competent authority publications, − the MOM and associated procedures, − the products in the scope of work, − maintenance data (significant ADs, SBs, etc.).

8 – Maintenance contracted − Sample check of maintenance records: − Existence and adequacy of the work order, − Data received from the maintenance organisation: − Valid CRS including any deferred maintenance, − List of removed and installed equipment and copy of the associated EASA Form 1 or equivalent.

− Obtain a copy of the current approval certificate (EASA Form 3) of the maintenance organisations contracted.

9 – Maintenance subcontracted Check that subcontractors for specialised services are properly controlled by the organisation.

10 – Technical records and record - keeping − Have the maintenance actions been properly recorded?

− Have the certificates (EASA Form 1 and Conformity certificates) been properly collected and recorded?

− Perform a sample check of technical records to ensure completeness and storage during the appropriate periods.

− Is storage of computerised data properly ensured?

11 – Occurrence reporting procedures − Check that reporting is properly performed.

− Actions taken and recorded.

Appendix XI to AMC M.A.708(c) — Contracted maintenance

ED Decision 2020/002/R 1. Maintenance contracts The following paragraphs are not intended to provide a standard maintenance contract, but to provide a list of the main points that should be addressed, when applicable, in a maintenance contract between the CAMO managing aircraft subject to Part - M and a maintenance organization approved in accordance with Part - 145 or Subpart F of Part M . The following paragraphs only address technical matters and exclude matters such as costs, delay, warranty, etc.

When maintenance is contracted to more than one maintenance organisation (for example, aircraft base maintenance to X, engine maintenance to Y, and line maintenance to Z1, Z2 and Z3), attention should be paid to the consistency of the different maintenance contracts.

A maintenance contract is not normally intended to provide appropriate detailed work instructions to personnel. Accordingly, there should be established organisational responsibilities, procedures and routines in the CAMO and the maintenance organisation t o cover these functions in a satisfactory way such that any person involved is informed about his/her responsibilities and the procedures that apply. These procedures and routines can be included/appended to the CAME and to the maintenance organisation’s m anual/MOE, or can consist in separate procedures. In other words, procedures and routines should reflect the conditions of the contract.

2. Aircraft/engine maintenance The following subparagraphs may be adapted to a maintenance contract that applies to aircraft base maintenance, aircraft line maintenance, and engine maintenance.

Aircraft maintenance also includes the maintenance of the engines and APU while they are installed on the aircraft.

2.1. Scope of work The type of maintenance to be performed by the maintenance organisation should be specified unambiguously. In case of line and/or base maintenance, the contract should specify the aircraft type and, preferably, should include the aircraft’s registrations.

In case of engine maintenance, the contract should specify the engine type.

2.2. Locations identified for the performance of maintenance/certificates held The place(s) where base, line or engine maintenance, as applicable, will be performed should be specified. The certificate held by the maintenance organisation at the place(s) where maintenance will be performed should be referred to in the contract. If ne cessary, the contract may address the possibility of performing maintenance at any location subject to the need for such maintenance arising either from the unserviceability of the aircraft or from the necessity to support occasional line maintenance.

2.3. Subcontracting The maintenance contract should specify under which conditions the maintenance organisation may subcontract tasks to a third party (regardless if this third party is approved or not). At least the contract should make reference to M.A.615 and 145.A.75 . Additional guidance is provided by the associated AMC/GM. In addition, the CAMO may require the maintenance organisation to obtain the CAMO approval before subcontracting to a third party. Access should be given to the CAMO to any information (especially the quality monitoring information) about the Powered by EASA eRules Page 329 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex I (Part - M) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM TO ANNEX I (Part - M) maintenance organisation’s subcontractors involved in the contract. It should, however, be noted that under the CAMO responsibility both the CAMO and its competent authority are entitled to be fully informed about subcontracting, although the competent aut hority will normally only be concerned with aircraft, engine and APU subcontracting.

2.4. Maintenance programme The maintenance programme, under which maintenance has to be performed, has to be specified.

The CAMO should have that maintenance programme approved by its competent authority.

2.5. Quality monitoring The terms of the contract should include a provision allowing the CAMO to perform a quality surveillance (including audits) of the maintenance organisation. The maintenance contract should specify how the results of the quality surveillance are taken into account by the maintenance organisation (see also paragraph 2.22. ‘Meetings’).

2.6. Competent authority involvement The contract should identify the competent authority(ies) responsible for the oversight of the aircraft, the operator, the CAMO, and the maintenance organisation. Additionally, the contract should allow competent authority(ies) access to the maintenance or ganisation.

2.7. Maintenance data The contract should specify the maintenance data and any other manual required for the fulfilment of the contract, and how these data and manuals are made available and kept current (regardless if they are provided by the CAMO or by the maintenance organis ation).

This may include but is not limited to: − maintenance programme, − airworthiness directives, − major repairs/modification data, − aircraft maintenance manual, − aircraft illustrated parts catalogue (IPC), − wiring diagrams, − troubleshooting manual, − Minimum Equipment List (normally on board the aircraft), − operator’s manual, − flight manual, − engine maintenance manual, − engine overhaul manual.

2.8. Incoming conditions The contract should specify in which condition the aircraft should be made available to the maintenance organisa tion. For extensive maintenance , it may be beneficial that a work scope planning meeting be organised so that the tasks to be performed may be commonly agreed (see also paragraph 2.23 ‘Meetings’).

Airworthiness directives and service bulletins/modifications The contract should specify the information that the CAMO is responsible to provide to the maintenance organisation, such as: − the status of the ADs including due date and the selected means of compliance, if applicable; and − status of modifications and the decision to embody a modification or an SB.

In addition, the contract should specify the type of information the CAMO will need in return to complete the control of ADs and modification status.

2.10. Hours and cycles control Hours and cycles control is the responsibility of the CAMO, and the contract should specify how the CAMO should provide the current hours and cycles to the maintenance organisation and whether the maintenance organisation should receive the current flight hours and cycles on a regular basis so that it may update the records for its own planning functions (see also paragraph 2.22 ‘Exchange of information’).

2.11. Life - limited parts and time - controlled components The control of life - limited parts and time - controlled components is the responsibility of the CAMO. The contract should specify whether the CAMO should provide the status of life - limited parts and time - controlled components to the maintenance organisation, and the information that the approved organisation wi ll have to provide to the CAMO about the removal/installation of the life - limited parts and time - controlled components removal/installation so that the CAMO may update its records (see also paragraph 2. 22 ‘Exchange of information’).

2.12. Supply of parts The contract should specify whether a particular type of material or component is supplied by the CAMO or by the maintenance organisation, which type of component is pooled, etc. The contract should clearly state that it is the maintenance organisation’s r esponsibility to be in any case satisfied that the component in question meets the approved data/standard and to ensure that the aircraft component is in a satisfactory condition for installation. Additional guidance on the acceptance of components is prov ided in M.A.402 and 145.A.42 .

2. 13. Pooled parts at line stations If applicable, the contract should specify how the subject of pooled parts at line stations should be addressed.

Appendix XIII to AMC M.A.712(f) — Organisational review

ED Decision 2020/002/R The following text provides relevant information for conducting organisational reviews in accordance with M.A.712 for the particular case of a CAMO working on aircraft subject to Part - M.

Organisational reviews may replace a full quality system in accordance with the provisions of M.A.712(f) and AMC M.A.712(f) and as described in the continuing airworthiness management exposition (CAME) Depending on the complexity of the small organisation (number and type of aircraft, number of different fleets, privilege to perform airworthiness reviews, etc.), the organisational review system may vary from a system using the principles and practices of a quality system (except for the requirement of independence) to a simplified system adapted to the low complexity of the organisation and the aircraft managed.

As a core minimum, the organisational review system should have the following features, which should be described in the CAME: a. Identification of the person responsible for the organisational review programme: By default, this person should be the accountable manager, unless he delegates this responsibility to (one of) the M.A.706(c) person(s).

b. Identification and qualification criteria for the person(s) responsible for performing the organisational reviews: These persons should have a thorough knowledge of the regulations and of the continuing airworthiness management organisation (CAMO) procedures. They should also have knowledge of audits, acquired through training or through experience (preferably as an au ditor, but also possibly because they actively participated in several audits conducted by the competent authority).

d. Performance of organisational reviews: Each checklist item should be answered using an appropriate combination of: − review of records, documentation, etc.

− sample check of aircraft under contract.

− interview of personnel involved.

− review of discrepancies and difficulty internal reports (e.g., notified difficulties in using current procedures and tools, systematic deviations from procedures, etc.).

− review of complaints filed by customers.

Management of findings and occurrence reports: − All findings should be recorded and notified to the affected persons.

− All level 1 findings, in the sense of M.A.716(a) , should be immediately notified to the competent authority and all necessary actions on aircraft in service should be immediately taken.

− All occurrence reports should be reviewed with the aim for continuous improvement of the system by identifying possible corrective and preventive actions. This should be done in order to find prior indicators (e.g., notified difficulties in using current p rocedures and tools, systematic deviations from procedures, unsafe behaviours, etc.), and dismissed alerts that, had they been recognised and appropriately managed before the event, could have resulted in the undesired event being prevented.

− Corrective and preventive actions should be approved by the person responsible for the organisational review programme and implemented within a specified time frame.

− The accountable manager should be notified of all significant findings and, on a regular basis, of the global results of the organisational review programme.

Following is a typical example of a simplified organisational review checklist, to be adapted as necessary to cover the CAME procedures: 1 – Scope of work − All aircraft under contract are covered in the Form 14 .

− The scope of work in the CAME does not disagree with the Form 14 .

− No work has been performed outside the scope of the Form 14 and the CAME.

− Is it justified to retain in the approved scope of work aircraft types for which the organisation has no longer aircraft under contract?

2 – Airworthiness situation of the fleet − Does the continuing airworthiness status (AD, maintenance programme, life limited components, deferred maintenance, ARC validity) show any expired items? If so, are the aircraft grounded?

3 – Aircraft maintenance programme − Check that all revisions to the TC/STC holders Instructions for Continuing Airworthiness, since the last review, have been (or are planned to be) incorporated in the maintenance programme, unless otherwise approved by the Competent Authority.

− Has the maintenance programme been revised to take into account all modifications or repairs impacting the maintenance programme?

− Have all maintenance programme amendments been approved at the right level (competent authority or indirect approval)?

− Does the status of compliance with the maintenance programme reflect the latest approved maintenance programme?

4 – Airworthiness Directives (and other mandatory measures issued by the competent authority) − Have all ADs issued since the last review been incorporated into the AD status?

− Does the AD status correctly reflect the AD content: applicability, compliance date, periodicity…? (sample check on ADs) 5 – Modifications/repairs − Are all modifications/repairs listed in the corresponding status approved in accordance with M.A.304 ? (sample check on modifications/repairs) − Have all the modifications/repairs which have been installed since the last review been incorporated in the corresponding status? (sample check from the aircraft/component logbooks) 6 – Relations with the owners/operators − Has a contract (in accordance with Appendix I to Part - M ) been signed with each external owner/operator, covering all the aircraft whose airworthiness is managed by the CAMO?

− Have the owners/operators under contract fulfilled their obligations identified in the contract? As appropriate: − Are the pre - flight checks correctly performed? (interview of pilots) − Are the technical log or equivalent correctly used (record of flight hours/cycles, defects reported by the pilot, identification of what maintenance is next due etc.)?

− Did flights occur with overdue maintenance or with defects not properly rectified or deferred? (sample check from the aircraft records) − Has maintenance been performed without notifying the CAMO (sample check from the aircraft records, interview of the owner/operator)?

7 – Personnel − Check that the current accountable manager and other nominated persons are correctly identified in the approved CAME.

− If the number of personnel has decreased or if the activity has increased, check that the organisation still has sufficient staff.

− Check that the qualification of all new personnel (or personnel with new functions) has been appropriately assessed.

− Check that the staff has been trained, as necessary, to cover changes in: − regulations, − competent authority publications, − the CAME and associated procedures, − the approved scope of work, − maintenance data (significant ADs, SBs, ICA amendments, etc.).

GM1 to Annex II (Part - 145) Definitions

ED Decision 2022/011/R For the purpose of the AMC & GM to Part - 145, the following definitions are used: Audit refers to a systematic, independent, and documented process for obtaining evidence, and evaluating it objectively to determine the extent to which requirements are complied with.

Note: Audits may include inspections.

Assessment in the context of management system performance monitoring, continuous improvement and oversight, refers to a planned and documented activity performed by competent personnel to evaluate and analyse the achieved level of performance and maturity in relatio n to the organisation’s policy and objectives.

Note: An assessment focuses on desirable outcomes and the overall performance, looking at the organisation as a whole. The main objective of the assessment is to identify the strengths and weaknesses to drive continual improvement.

Remark: For ‘risk assessment’, please refer to the definition below.

Base Ref. AMC1 145.A.10 maintenance Base refers to a closed facility that can house an aircraft and protect it from environmental maintenance conditions.

hangar Competency is a combination of individual skills, practical and theoretical knowledge, attitude, training, and experience.

Correction is the action to eliminate a detected non - compliance.

Corrective action is the action to eliminate or mitigate the root cause(s) and prevent the recurrence of an existing detected non - compliance, or other undesirable conditions or situations. Proper determination of the root cause(s) is crucial for defining effective corrective actions to prevent reoccurrence.

Powered by EASA eRules Page 342 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) GENERAL Error is an action or inaction by a person that may lead to deviations from accepted procedures or regulations.

Note: Errors are often associated with occasions when a planned sequence of mental or physical activities either fails to achieve its intended outcome, or is not appropriate with regard to the intended outcome, and when results cannot be attributed purely to chance.

Fatigue is a physiological state of reduced mental or physical performance capability resulting from sleep loss or extended wakefulness, circadian phase, or workload (mental and/or physical activity) that can impair a person’s alertness and ability to safely perfo rm his or her tasks.

Hazard is a condition or an object with the potential to cause or contribute to an aircraft incident or accident.

Human factors is anything that affects human performance, which means principles that apply to aeronautical activities, and which seek safe interface between the human and other system components by proper consideration of human performance.

Human refers to human capabilities and limitations which have an impact on the safety and performance efficiency of aeronautical activities.

Inspection in the context of compliance monitoring and oversight, refers to an independent documented conformity evaluation by observation and judgement accompanied, as appropriate, by measurement, testing or gauging, in order to verify compliance with applicable req uirements.

Note: Inspection may be part of an audit (e.g. product audit), but may also be conducted outside of the normal audit plan; for example, to verify closure of a particular finding.

Just culture Ref. Regulation (EU) No 376/2014, Article 2.

Line maintenance Ref. AMC1 145.A.10 Near miss is an event in which an occurrence to be mandatorily reported according to Regulation (EU) No 376/2014 was narrowly averted or avoided.

Example: A mechanic on rechecking his or her work at the end of a task realises that one work card step was not properly carried out.

Organisational is a condition that affects the effectiveness of safety risk controls, related to the culture, factor policies, processes, resources, and workplace of an organisation.

Oversight refers to the time frame within which all areas of the approval and all processes should planning cycle be reviewed by the competent authority by means of audits and inspections.

Oversight refers to the detailed oversight schedule that defines the number of audits and programme inspections, the scope and duration of each audit and inspection, including details of product audits and locations, as appropriate, to be performed by the competent authority, and the tentative time frame for performing each audit and inspection.

Preventive action is the action to eliminate the cause of a potential non - compliance or other undesirable potential situations.

is an evaluation based on engineering and operational judgement and/or analysis Risk assessment methods in order to establish whether the achieved or perceived risk is acceptable or tolerable.

Safety culture is an enduring set of values, norms, attitudes, and practices within an organisation concerned with minimising the exposure of the workforce and the general public to Powered by EASA eRules Page 343 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) GENERAL dangerous or hazardous conditions. In a positive safety culture, a shared concern for, commitment to, and accountability for safety is promoted.

Safety risk refers to the predicted probability and severity of the consequences or outcomes of a hazard.

Safety training refers to dedicated training to support safety management policies and processes, including human factors training.

Note: The main purpose of the safety training programme is to ensure that personnel at all levels of the organisation maintain their competency to fulfil their roles safely. Safety training should, in particular, consider the safety knowledge derived from hazard identification and risk management processes, and support the fostering of a positive safety cultu re.

Note: Safety management training refers to specific training for the staff involved in safety management functions in accordance with point 145.A.30(ca) or 145.A.200(a)(3) .

Working days refer to days between and including Monday to Friday, not including public holidays.

REQUIREMENTS

145.A.10 Scope

Regulation (EU) 2021/1963 This Section establishes the requirements to be met by an organisation to qualify for the issue or continuation of an approval certificate for the maintenance of aircraft and components.

AMC 1 145.A.10 Scope

ED Decision 2022/011/R LINE MAINTENANCE AND BASE MAINTENANCE (a) ‘Line maintenance’ refers to limited maintenance for the aircraft suitable to be carried out whilst the aircraft remains in the air operation environment.

Line m aintenance may include: − t rouble shooting ; − d efect rectification ; − c omponent replacement with use of external test equipment if required. Component replacement may include components such as engines and propellers ; − maintenance that will detect obvious unsatisfactory conditions/discrepancies /malfunctions , but do es not require extensive in - depth inspection. It may also include internal structure, systems and powerplant items which are visible through quick opening access panels/doors /ports; − repairs , modifications and other maintenance tasks which do not require extensive disassembly and can be accomplished by simple means.

(b) ‘Base maintenance’ refers to any maintenance for the aircraft other than line maintenance.

(c) Organisations maintaining aircraft should have a procedure to determine whether the tasks or groups of tasks to be carried out fall under the line maintenance or base maintenance scope of the organisation, with due regard to the expected duration of the ma intenance, number and type of tasks, shifts and disciplines involved, work environment, etc.

For temporary or occasional cases, the organisation may also have a procedure which allows, subject to a task assessment (including all relevant aspects and conditions), to conduct a base maintenance task under line maintenance environment .

(d) In particular, maintenance tasks of aircraft subject to ‘progressive’ or ‘equalised’ maintenance programmes should be individually assessed in respect of such procedure to ensure that all the tasks within the particular check can be carried out safely and to the required standards at the designated line maintenance station.

ED Decision 2022/011/R SMALL ORGANISATIONS This Guidance Material (GM) provides guidance on how the following small organisations satisfy the intent of Part - 145 : (a) Organisations that only employ one person, who carries out the certification function and other functions, and that are approved under Part - 145 may use the alternatives provided below limited to the following terms of approval : − Class A2 Base and line maintenance of aeroplanes of 5 700 kg maximum take - off mass (MTOM) or less ( with piston engines only) − Class A3 Base and line maintenance of single - engined helicopters of 3 175 kg MTOM or less − Class A4 Aircraft other than A1, A2 and A3 aircraft − Class B2 Piston engines with maximum output of less than 450 HP − Class C Components − Class D1 Non - destructive testing 145.A.30(b) : The minimum requirement is for one full - time person who meets the Part - 66 requirements for certifying staff and holds the position of ‘accountable manager, safety manager, maintenance engineer and is also certifying staff and, if applicable, airworthiness review staff’. No other person may issue a certificate of release to service and therefore if that person is absent, no maintenance may be released during such absence.

(1) The independent audit element of the compliance monitoring function of point 145.A.200(a)(6) may be sub contracted to an appropriate organisation approved under Part - 145 or contracted to a person with appropriate technical knowledge and extensive experience of audits , working under the management system of the organisation, with the agreement of the competent authority.

Note: ‘Full - time’ for the purpose of Part - 145 means not less than 35 hrs per week except during vacation periods.

(2) 145.A.35 . In the case of an approval based on one person using a n independent audit monitoring arrangement as referred to in point (1) , the requirement for a record of certifying staff is satisfied by the submission to and acceptance by the competent authority of the MOE . With only one person , the requirement for a separate record of authorisation is unnecessary because the EASA Form 3 certificate defines the authorisation. An appropriate statement, to reflect this situation, should be included in the exposition.

(3) 145.A.200(a)(6) . It is the responsibility of the organisation or person referred to in point (1) to make a minimum of two on - site audits every year, and it is the responsibility of this organisation or person to carry out these activities on the basis of one pre - announced visit and one un announced visit to the maintenance organisation.

It is the responsibility of the Part - 145 organisation to ensure that effective implementation of all corrective actions takes place.

(1) 145.A.30(b) and 145.A.30(c) : The normal minimum requirement is for the employment on a full - time basis of two persons who meet the applicable requirements for certifying staff, whereby one holds the position of ‘maintenance engineer’ and the other holds the position of ‘ compliance monitoring engineer’.

Either person can assume the responsibilities of the accountable manager and safety manager provided that they can comply in full with the applicable elements of points 145.A.30(a) and 145.A.30(ca) , but the ‘maintenance engineer’ is the certifying person in order to retain the independence of the ‘ compliance monitoring engineer’ to carry out audits. Nothing prevents either engineer from undertaking maintenance tasks provided that the ‘maintenance engineer’ issues the certificate of release to service. This ‘maintenance engineer’ may also be nominated as airworthiness review staff to carry out airworthiness reviews and to issue the corresponding airworthiness review certificate for aircraft for which Part - ML applies in accordance with ML.A.903 .

The ‘ compliance monitoring engineer’ should have similar qualifications and status to the ‘maintenance engineer’ for reasons of credibility, unless he/she has a proven track record in aircraft compliance monitoring , in which case some reduction in the extent of his or her maintenance qualifications may be permitted.

In cases where the competent authority agrees that it is not practical for the organisation to nominate a person responsible for the independent audit of the compliance monitoring function, this element may be arranged in accordance with point (a)(1).

145.A.15 Application for an organisation certificate

Regulation (EU) 2021/1963 (a) An application for a certificate or an amendment to an existing certificate in accordance with this Annex shall be made in a form and manner established by the competent authority, taking into account the applicable requirements of Annex I (Part - M) , Annex Vb (Part - ML) and this Annex.

AMC 1 145.A.25(a) Facility requirements

ED Decision 2022/011/R 1. Where the hangar is not owned by the organisation, it may be necessary to establish proof of tenancy. In addition, sufficiency of hangar space to carry out planned base maintenance should be demonstrated by the preparation of a projected aircraft hangar visit plan relative to the intended maintenance activities . The aircraft hangar visit plan should be updated on a regular basis.

2. Protection from the weather elements relates to the normal prevailing local weather elements that are expected throughout any twelve month period. Aircraft hangar and component workshop structures should prevent the ingress of rain, hail, ice, snow, win d and dust etc.

Aircraft hangar and component workshop floors should be sealed to minimise dust generation.

3. For line maintenance of aircraft, hangars are not essential but it is recommended that access to hangar accommodation be demonstrated for usage during inclement weather for minor scheduled work and lengthy defect rectification.

4. Subject to a risk assessment and agreement by the competent authority, the organisation may use facilities at the approved location other than a base maintenance hangar for certain aircraft base maintenance tasks, provided that those facilities offer level s of weather and environmental protection that are equivalent to those of a base maintenance hangar, as well as a suitable working environment for the particular work package. This does not exempt an organisation from the requirement to have a base main tenance hangar in order to be approved to conduct base maintenance at a given location.

ED Decision 2022/011/R RESPONSIBILITY OF THE NOMINATED PERSONS TO THE ACCOUNTABLE MANAGER There are different ways to set up the organisation including the possibility to have managerial layers between the accountable manager and the nominated person. But the key principle is that, regardless of the arrangement, there is one nominated person re sponsible for each Part - 145 function, this responsibility is recognised by that nominated person and the accountable manager, and a direct communication channel exists between them. The nominated person’s responsibility should not be diluted into the various levels of management and should be free of conflicts of interest.

AMC 1 145.A.30(d) Personnel requirements

ED Decision 2022/011/R SUFFICIENT NUMBER OF PERSONNEL 1. Has sufficient staff means that the organisation employs or contracts competent staff, as detailed in the man - hour plan, of which at least half the staff that perform maintenance in each workshop, hangar or flight line on any shift should be employed to ensure organisational stability. For the purpose of meeting a specific operational necessity, a temporary increase of the proportion of contracted staff may be permitted to the organisation by the competent authority, in accordance with an approved proced ure which should describe the extent, specific duties, and responsibilities for ensuring adequate organisation stability. For the purpose of this subparagraph, employed means the person is directly employed as an individual by the maintenance organisation approved under Part - 145 , whereas contracted means the person is employed by another organisation and contracted by that organisation to the maintenance organisation approved under Part - 145 .

2. The maintenance man - hour plan should take into account all maintenance activities carried out outside the scope of the Part - 145 approval.

The planned absence (for training, vacations, etc.) should be considered when developing the man - hour plan.

3. The maintenance man - hour plan should relate to the anticipated maintenance work load except that when the organisation cannot predict such workload, due to the short term nature of its contracts, then such plan should be based upon the minimum maintenan ce workload needed for commercial viability. Maintenance work load includes all necessary work such as, but not limited to, planning, maintenance record checks, production of worksheets/cards in paper or electronic form, accomplishment of maintenance, insp ection and the completion of maintenance records.

4. For aircraft base maintenance, the maintenance man - hour plan should relate to the aircraft hangar visit plan as specified in AMC 1 145.A.25(a) .

5. For aircraft component maintenance, the maintenance man - hour plan should relate to the aircraft component planned maintenance as specified in point 145.A.25(a)(2) .

6. The man - hours allocated to the compliance monitoring function should be sufficient to meet the requirement of point 145.A.200(a)(6) which means taking into account the AMC to 145.A.200(a)(6) . Where compliance monitoring staff also perform other functions, the time allocated to those functions needs to be taken into account in determining the number of compliance monitoring staff.

7. The maintenance man - hour plan should be reviewed at least every 3 months and updated when necessary.

8. Significant deviation from the maintenance man - hour plan should be reported through the departmental manager to the compliance monitoring manager and the accountable manager for review. It may also be reported through the internal safety reporting scheme. A significant deviation means that there is more than a 25% shortfall in available man - hours during a calendar month for any one of the functions specified in point 145.A.30(d) .

9. In addition, as part of its management system in accordance with point 145.A.200 , the organisation should have a procedure to assess and mitigate the risks: (1) if the actual number of staff available is less than the planned staffing level for any particular work shift or period; Powered by EASA eRules Page 359 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS (2) if there is a temporary increase in the proportion of contracted staff in order to meet specific operational needs.

AMC1 145.A.30(e) Personnel requirements

ED Decision 2022/011/R COMPETENCY ASSESSMENT OBJECTIVES The procedure referred to in 145.A.30(e) should require amongst others that planners, mechanics, specialised services staff, supervisors, certifying staff and support staff, whether employed or contracted, are assessed for competency before unsupervised work commences and competency is controlle d on a continuous basis.

Competenc y should be assessed by the evaluation of: − on - the - job performance and/or testing of knowledge by appropriately qualified personnel, and − records for basic, organisational , or tasks training and/or product type and differences training, and − experience records.

Validation of the above could include a confirmation check with the organisation(s) that issued the document(s). For that purpose, experience/training may be recorded in a document such as a log book, or based on the suggested template in GM3 145.A.30(e) .

As a result of this assessment, an individual’s qualifications should determine: − the scope of tasks this individual is authorised to perform and/or supervise and/or sign off (as applicable) or which level of ongoing supervision would be required; − whether there is a need for additional training.

A record should be kept of each individual’s qualifications and competency assessment (refer also to point 145.A.55(d) ). This should include copies of all documents that attest to their qualifications, such as a licence and/or any authorisation held, as applicable.

For a proper competency assessment of its personnel, the organisation should consider that: 1. In accordance with the job function, adequate initial and recurrent training has been received by the staff and recorded to ensure continued competency so that it is maintained throughout the duration of the employment/contract.

2. All staff should be able to demonstrate knowledge of , and compliance with, the maintenance organisation’s procedures, as applicable to their duties.

3. All staff should be able to demonstrate an understanding of the safety management principles, including human factors related to their job function, and be trained as per AMC4 145.A.30(e) .

4. To assist in the assessment of competency and to establish the training needs analysis, job descriptions are recommended for each job function in the organisation. Job descriptions should contain sufficient criteria to enable the required competency assessment.

Criteria should allow the assessment to establish that, among other aspects (titles might be different in each organisation): − Managers are able to properly manage the work output, processes, resources and priorities described in their assigned duties, accountabilities and responsibilities in accordance with the safety policy and objectives and in compliance with the applicable requirements.

− Planners are able to interpret maintenance requirements into maintenance tasks, and have an understanding that they have no authority to deviate from the maintenance data. They are able to organise maintenance activities in an effective manner and in consideration of human performance limitations.

− Supervisors are able to ensure that all the required maintenance tasks are carried out and, if they are not completed or it is evident that a particular maintenance task cannot be carried out according to the maintenance data, that these problems will be adequately addressed to eliminate the non - compliance, and reported through the internal safety reporting scheme to prevent their reoccurrence. In addition, for those supervisors, who also carry out maintenance tasks, the assessment should ensure that they u nderstand that such tasks should not be undertaken if they are incompatible with their management responsibilities.

− Mechanics are able to carry out maintenance tasks to any standard specified in the maintenance data , and will notify their supervisors of any defects or mistakes requiring rectification to re - establish the required maintenance standards.

− Specialised services staff are able to carry out specialised maintenance tasks to the standard specified in the maintenance data. They should be able to communicate with their supervisors and report accurately when necessary.

− Support staff are able to determine that the relevant tasks or inspections have been carried out to the required standard.

− Certifying staff are able to determine when the aircraft or aircraft component maintenance is ready to be released to service and when it should not be released to service.

− Compliance monitoring staff are able to monitor compliance with this Regulation and to identify non - compliances in an effective and timely manner so that the organisation may remain in compliance with this Regulation.

− Staff who have safety management responsibilities are familiar with the relevant processes in terms of hazard identification, risk management, and the monitoring of safety performance.

− All staff are familiar with the safety policy and the procedures and tools that can be used for internal safety reporting.

The competenc y assessment should be based upon the procedure specified in GM2 145.A.30(e) .

AMC2 145.A.30(e) Personnel requirements

ED Decision 2022/011/R COMPETENCY ASSESSMENT PROCEDURE (a) The organisation should develop a procedure that describes the process for conducting competency assessments of personnel. The procedure should specify: (1) the persons who are responsible for this process; (2) when the assessments should take place; (3) how to give credit from previous assessments; (4) how to validate qualification records; (5) the means and methods to be used for the initial assessment; (6) the means and methods to be used for the continuous control of competency, including how to gather feedback on the performance of personnel; (7) the aspects of competencies to be observed during the assessment in relation to each job function; (8) the actions to be taken if the assessment is not satisfactory; and (9) how to record the assessment results.

(b) Competency may be assessed by having the person work under the supervision of another qualified person for a sufficient time to arrive at a conclusion. Sufficient time could range from several days to several weeks depending on the complexity of the ta sk(s) and the work exposure. The person need not be assessed against the complete spectrum of their intended duties. If the person has been recruited from another approved maintenance organisation, a written confirmation from the previous organisation coul d be taken into consideration to reduce the duration of the assessment.

AMC 4 145.A.30(e) Personnel requirements

ED Decision 2022/011/R SAFETY TRAINING (INCLUDING HUMAN FACTORS) (a) With respect to the understanding of the application of safety management principles (including human factors), all maintenance organisation personnel should be assessed for the need to receive initial safety training.

Personnel involved in the delivery of the basic maintenance service of the organisation should receive both initial and recurrent safety training, appropriate for their responsibilities. This should include at least the following staff members: − Nominated persons, line managers, supervisors; − Certifying staff, support staff and mechanics; − Technical support personnel such as planners, engineers, technical record staff; − Persons involved in compliance monitoring and/or safety management - related processes and tasks, including the application of human factors principles, internal investigations and safety training; − Specialised services staff; − Stores department staff, purchasing department staff; − Ground equipment operators.

The generic term ‘line managers’ refers to departmental heads or persons responsible for operational departments or functional units that are directly involved in the delivery of the basic maintenance services of the organisation.

(b) Initial safety training should cover all the topics of the training syllabus specified in GM1 145.A.30(e) either as a dedicated course or else integrated within other training. The syllabus may be adjusted to reflect the particular nature of the organisation. The syllabus may also be adjusted to suit the particular nature of work for each function within the organisation.

For example: − small organisations not working in shifts may cover in less depth subjects related to teamwork and communication; − planners may cover in more depth the scheduling and planning objectives of the syllabus, and in less depth the objective of developing skills for shift working.

All personnel identified in accordance with point (a) of this AMC, including personnel being recruited from any other organisation should receive initial safety training compliant with the organisation’s training standards prior to commencing the actual jo b function, unless their competency assessment justifies that there is no need for such training. New, directly employed personnel working under direct supervision may receive training within 6 months after joining the maintenance organisation.

(c) The purpose of recurrent safety training is primarily to ensure that staff remain current in terms of SMS principles and human factors and also to collect feedback on safety and human factors issues. Consideration should be given to involving complianc e monitoring staff and the key safety management personnel in this training to provide a consistent presence and facilitate feedback. There should be a procedure to ensure that feedback is formally reported by the trainers through the internal safety repor ting scheme to initiate action where necessary.

ED Decision 2022/011/R TRAINING SYLLABUS FOR INITIAL SAFETY TRAINING (INCLUDING HUMAN FACTORS) The training syllabus below identifies the topics and subtopics to be addressed during the safety training.

The maintenance organisation may combine, divide, or change the order of any of the subjects in the syllabus to suit its own needs, as long as all the subjects are covered to a level of detail appropriate to the organisation and its personnel, including the varying level of seniority of that personnel.

Some of the topics may be covered in separate training courses (e.g. health and safety, management, supervisory skills, etc.) in which case duplication of training is not necessary.

Where possible, practical illustrations and examples should be used, especially accident and incident reports.

Topics should be related to existing legislation, where relevant. Topics should be related to existing guidance/advisory material, where relevant (e.g. ICAO HF Digests and Training Manual).

Topics should be related to the maintenance activities of the organisation to the greatest extent possible; too much unrelated theory should be avoided.

3. The requirement of having appropriate aircraft - rated certifying staff qualified as category B1, B2, B2L, B3, L, as appropriate, in the case of aircraft line maintenance does not imply that the organisation must have B1, B2 , B2L, B3 and L personnel at every line station. The MOE should have a procedure on how to deal with defects requiring those categories of certifying staff.

Powered by EASA eRules Page 374 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS 4. The competent authority may accept that in the case of aircraft line maintenance an organisation has only B1, B2 , B2L, B3 or L certifying staff, as appropriate, provided that the competent authority is satisfied that the scope of work, as defined in the MOE , does not need the availability of all those categories of certifying staff. Special attention should be taken to clearly limit the scope of scheduled and non - scheduled line maintenance (defect rectification) to only those tasks that can be certified by the available category of certifying staff.

AMC 1 145.A.30(h) Personnel requirements

ED Decision 2022/011/R In accordance with points 145.A.30(h) and 145.A.35 , the qualification requirements (basic licence, aircraft ratings, recent experience and recurrent training) are identical for certifying staff and for support staff. The only difference is that support staff cannot hold certification privileges when performing this role since during base maintenance , the release to service will be issued by category C certifying staff.

Nevertheless, the organisation may use as support staff (for base maintenance) persons who already hold certification privileges for line maintenance.

AMC 1 145.A.30(j)(4) Personnel requirements

ED Decision 2022/011/R 1. For the issue of a limited certification authorisation , the pilot should hold either an airline transport pilot s licence (ATPL) or a commercial pilot licence (CPL) in accordance with Regulation (EU) No 1178/2011 and, as applicable, Regulation (EU) 2020/723 .

2. In addition , the limited certification authorisation is subject to the MOE containing procedures to address the personnel requirements of point 145.A.30(e) . The procedures should be accepted by the competent authority and should include as a minimum: (a) completion of adequate continuing airworthiness regulation training as related to maintenance; (b) completion of adequate task training for the specific task(s) on the aircraft.

The validity of the authorisation should be limited to twelve months, and may be renewed if there has been satisfactory recurrent training on the task(s) for which the pilot holds an authorisation.

AMC 1 145.A.30(j)(5) Personnel requirements

ED Decision 2022/011/R 1. For the purposes of point 145.A.30(j)(5) , ‘unforeseen’ means that the grounding of the aircraft could not reasonably have been predicted by the operator because the defect was unexpected, due to it being part of a hitherto reliable system.

2. Issuing a one - off authorisation should only be considered under the responsibility of the compliance monitoring manager of the contracted organisation after a reasoned judgement has been made that such an authorisation is appropriate under the circumstance s, while at the same time it maintains the required airworthiness standards. The organisation’s compliance monitoring personnel should assess each situation individually prior to issuing a one - off authorisation, and may request contribution from technic al and safety management personnel.

3. A one - off authorisation should not be issued if the level of certification required could exceed the knowledge and experience level of the person it is issued to. In all cases, due consideration should be given to the complexity of the work involved and the availability of the required tooling and/or test equipment needed to complete the work.

AMC 145.A.30(j)(5)(i) Personnel requirements

ED Decision 2022/011/R I n case it is necessary to issue a one - off certification authorisation to a certifying staff on an aircraft type for which he or she does not hold a type - rated authorisation, the following procedure is recommended: 1. The flight crew should communicate full details of the defect to the maintenance organisation.

If necessary, the maintenance organisation will then request the use of a one - off authorisation from the compliance monitoring personnel.

2. When issuing a one - off authorisation, the compliance monitoring personnel should verify that: (a) full technical details relating to the work required to be carried out have been established and passed on to the certifying staff;.

(b) the organisation has an approved procedure in place for coordinating and controlling the total maintenance activity undertaken at the location under the authority of the one - off authorisation;.

(c) the person to whom a one - off authorisation is issued has been provided with all the necessary information and guidance relating to maintenance data, and any special technical instructions associated with the specific task undertaken. A detailed step - by - ste p worksheet has been defined by the organisation, and has been communicated to the holder of the one - off authorisation; (d) the person holds authorisations of equivalent levels and scopes on other aircraft types that have similar technology, construction and systems.

3. The holder of the one - off authorisation should sign off the detailed step - by - step worksheet when completing the work steps. The completed tasks should be verified by visual examination Powered by EASA eRules Page 376 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS and/or normal system operation upon return to an appropriately approved Part - 145 maintenance facility.

AMC 145.A.35(a) Certifying staff and support staff

ED Decision 2022/011/R 1. Holding a Part - 66 licence with the relevant type/group rating, or a national qualification in the case of components, does not mean by itself that the holder is qualified to be authorised as certifying staff and/or support staff. The organisation is responsible for assess ing the competenc y of the holder for the scope of the maintenance to be authorised.

2. The sentence ’the organisation shall ensure that certifying staff and support staff have an adequate understanding of the relevant aircraft and/or components to be maintained together with the associated organisation procedures‘ means that the person has r eceived training and has been successfully assessed on: − the type of aircraft or component; − the differences on: − the particular model/variant; − the particular configuration.

The organisation should specifically ensure that the individual competencies have been established with regard to: − relevant knowledge, skills and experience in the product type and configuration to be maintained, taking into account the differences between the generic aircraft type rating training that the person received and the specific configuration of the aircraft to be maintained.

− appropriate attitude towards safety and observance of procedures.

− knowledge of the associated organisation and operator procedures (i.e. handling and identification of components, MEL use, Technical Log use, independent checks, etc.).

3. Some special maintenance tasks may require additional specific training and experience, including but not limited to: − in - depth troubleshooting; Powered by EASA eRules Page 379 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS − very specific adjustment or test procedures; − rigging; − engine run - up, starting and operating the engines, checking engine performance characteristics, normal and emergency engine operation, associated safety precautions and procedures; − extensive structural/system inspection and repair; − other specialised maintenance required by the maintenance programme.

For engine run - up training, simulators and/or real aircraft should be used.

4. The assessment of the competenc y of the holder should be conducted in accordance with a procedure approved by the competent authority (item 3.9 of the MOE, as described in AMC 1 145.A.70(a) ).

5. The organisation should hold copies of all the documents that attest to the competenc y and recent experience of the holder for the period described in point 145.A.55(d)(4) .

Additional information is provided in AMC 66.A.20(b)3 .

AMC 145.A.35(b) Certifying staff and support staff

ED Decision 2015/029/R The organisation issues the certification authorisation when satisfied that compliance has been established with the appropriate paragraphs of Part - 145 and Part - 66 . In granting the certification authorisation the maintenance organisation approved under Part - 145 needs to be satisfied that the person holds a valid Part - 66 aircraft maintenance licence and may need to confirm such fact with the competent authority of the Member State that issued the licence.

AMC 145.A.35(c) Certifying staff and support staff

ED Decision 2015/029/R For the interpretation of ‘6 months of actual relevant aircraft maintenance experience in any consecutive 2 - year period’, the provisions of AMC 66.A.20(b)2 are applicable.

AMC 1 145.A.35(d) Certifying staff and support staff

ED Decision 2022/011/R 1. Recurrent training is a two - way process to ensure that certifying staff and support staff remain current in terms of the necessary technical knowledge, procedures, and safety management (including human factors), and that the organisation receives feedback on the adequacy of its procedures and maintenance instructions. Due to the interactive nature of this training, consideration should be given to involving the compliance monitoring staff and the key safety management personnel in this training to provi de a consistent presence and facilitate feedback.

There should be a procedure to ensure that feedback is formally reported by the trainers through the internal safety reporting scheme to initiate action where necessary.

2. Recurrent training should cover changes made to the modification standard of the products being maintained, to the relevant requirements such as Part - 145 , to the organisation’s procedures, safety policy and objectives, as well as human factors and safety issues identified from internal or external analysis of incidents and compliance monitoring results. It should also address instances in which staff faile d to follow the procedures, and the reasons why particular Powered by EASA eRules Page 380 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS procedures were not always followed. In many cases, the recurrent training will reinforce the need to follow the procedures and will ensure that incomplete or incorrect procedures are identified to the company so that they can be corrected. It may be neces sary to carry out an audit of these procedures.

3. Recurrent training should be of sufficient duration in each 2 - year period to meet the intent of point 145.A.35(d) and may be split into a number of separate elements. Point 145.A.35(d) requires such a training to keep certifying staff and support staff updated in terms of relevant technology, procedures, safety management and human factors issues which means it is one part of ensuring compliance. Therefore, sufficient duration should be related to relevant audit findings and other internal / external sources of information available to the organisation on human errors and safety issues in maintenance. This means that in the case of an organisation that maintains aircraft with limited rel evant audit findings, hazards and related safety risks identified, recurrent training could be limited to days rather than weeks, whereas in the case of a similar organisation with a number of relevant audit findings, hazards and related safety risks ident ified, such a training may take several weeks. For an organisation that maintains aircraft components, the duration of recurrent training would follow the same philosophy but should be scaled down to reflect the more limited nature of the activity. For exa mple, certifying staff who release hydraulic pumps may only require a few hours of recurrent training, whereas those who release turbine engines may only require a few days of such a training. The content of recurrent training should be related to relevant audit findings, hazards and related safety risks identified. It is recommended that such training is reviewed at least once in every 24 - month period.

4. The method of training is intended to be a flexible process, and this training could, for example, be provided by a Part - 147 organisation, an aeronautical college, the Part - 145 organisation, or another training or maintenance organisation. The elements, general content and length of such training should be specified in the MOE.

AMC 1 145.A.35(e) Certifying staff and support staff

ED Decision 2022/011/R The programme for recurrent training should list all certifying staff and support staff and when the training will take place, the elements of such a training, and an indication that it was carried out on time as planned. Such information should subsequent ly be transferred to the certifying staff and to the support staff records as required by point 145.A.55(d)(3) .

ED Decision 2022/011/R As stated in point 145.A.35(f) , except where any of the unforeseen cases of point 145.A.30(j)(5) applies, all prospective certifying staff and support staff should be assessed for their competenc y related to their intended duties. Said assessment should be conducted in accordance with AMC 1 , 2 , 3 , 4 and 5 to point 145.A.30(e), as applicable.

AMC 1 145.A.35( m ) Certifying staff and support staff

ED Decision 2022/011/R 1.

2. ‘Appropriately approved in accordance with Annex IV (Part - 147) ’ means an organisation holding an approval to provide category A task training for the corresponding aircraft type.

3. ‘Appropriately approved in accordance with Annex II (Part - 145) ’ means an organisation holding a maintenance organisation approval for the corresponding aircraft type.

AMC 1 145.A.35( n ) Certifying staff and support staff

ED Decision 2022/011/R 1. The privilege for a B2 licence holder to release minor scheduled line maintenance and simple defect rectification in accordance with 66.A.20(a)(3)(ii) can only be granted by the Part - 145 approved organisation where the licence holder is employed/contracted after meeting all the requirements specified in 145.A.35(o) . This privilege cannot be transferred to another Part - 145 approved organisation.

2. When a B2 licence holder already holds a certifying staff authorisation containing minor scheduled line maintenance and simple defect rectification for a particular aircraft type, new tasks relevant to category A can be added to that type without requir ing another 6 months of experience. However, task training (theoretical plus practical hands - on) and examination/assessment for these additional tasks is still required.

3. When the certifying staff authorisation intends to cover several aircraft types, the experience may be combined within a single 6 - month period.

4. For the addition of new types to the certifying staff authorisation, another 6 months should be required unless the aircraft is considered similar per AMC 66.A.20(b)2 to the one already held.

5. The term ‘6 months of experience’ may include full - time employment or part - time employment.

The important aspect is that the person has been involved during a period of 6 months (not necessarily every day) in those tasks which are going to be part of th e authorisation.

The control of these tools and equipment requires that the organisation has a procedure to inspect/service and, where appropriate, calibrate such items on a regular basis and indicate to users that the item is within any inspection or service or calibration time - limit. A clear system of labelling all tooling, equipment and test equipment is therefore necessary giving information on when the next inspection or service or calibration is due and if the item is unserviceable for any other reason where it may not be obvious. A register should be maintained for all precision tooling and equipment together with a record of calibrations and standards used.

2. Inspection, service or calibration on a regular basis should be in accordance with the equipment manufacturers' instructions except where the organisation can show by results that a different time period is appropriate in a particular case.

The use of such suppliers does not exempt the organisation from its obligations under 145.A.42 to ensure that supplied components and materials are in satisfactory condition and meet the applicable criteria of 145.A.42.

(c) Supplier evaluation may depend on different factors, such as the type of component, whether or not the supplier is the manufacturer of the component, the TC holder or the declarant of a declaration of design compliance or a maintenance organisation, or even specific circumstances such as aircraft on ground. This evaluation may be limited to a questionnaire from the Part - 145 organisation to its suppliers, a desktop evaluation of the supplier’s procedures or an on - site audit, if deemed necessary.

GM1 145.A.42(b)(ii) Components

ED Decision 2021/009/R INSTALLATION OF COMPONENTS Components, standard parts and materials should only be installed when they are specified in the applicable maintenance data as specified in 145.A.45(b) . So, the installation of a component, standard part or material can only be done after checking the applicable maintenance data.

This check should ensure that the part number, modification status, limitations, etc., of the component, standard part or material are the ones specified in the applicable maintenance data of the particular aircraft or component where the component, standa rd part or material is going to be installed. The organisation should establish procedures to ensure that this check is performed before installation.

AMC1 14 5.A.42(b)(iii) Components

ED Decision 2023/013/R FABRICATION OF PARTS FOR INSTALLATION (a) The agreement of the competent authority on the fabrication of parts by the approved maintenance organisation should be formalised through the approval of a detailed procedure in the Maintenance Organisation Exposition (MOE). This AMC contains principles a nd conditions to be taken into account for the preparation of an acceptable procedure.

(b) Fabrication, inspection, assembly and test should be clearly within the technical and procedural capability of the organisation.

(c) All necessary data to fabricate the part should be approved either by the Agency or the type certificate (TC) holder, or Part 21 design organisation approval holder, or supplemental type certificate (STC) holder , or should be declared by the declarant of a declaration of design compliance or, if applicable for a minor change, by a Part 21 design organisation approval holder.

Powered by EASA eRules Page 391 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS (d) Items that are fabricated by an organisation approved under Part - 145 may only be used by that organisation in the course of overhaul, maintenance, modifications, or repair of aircraft or components, performing work at its own facilities. The permission to fabricate does not constitute approval for manufacture, or to supply externally, and the parts do not qualify for EASA Form 1 certification. This prohibition also applies to the bulk transfer of surplus inventory, in that locally fabricated parts are physically segregated and excluded from any delivery certification.

(e) Fabrication of parts, modification kits, etc., for onward supply and/or sale may not be conducted by an organisation that is approved under Part - 145.

(f) The data specified in (c) may include repair procedures that involve the fabrication of parts.

Where the data on such parts is sufficient to facilitate fabrication, the parts may be fabricated by an organisation that is approved under Part - 145. Care sh ould be taken to ensure that the data include details of part numbering, dimensions, materials, processes, and any special manufacturing techniques, special raw material specification and/or incoming inspection requirement, and that the approved organisati on has the necessary capability to fabricate those parts. That capability should be defined by way of exposition content. Where special processes or inspection procedures are defined in the approved or declared (in accordance with Part 21 Light Subpart C) data, which are not available at the organisation, the organisation cannot fabricate the part unless the TC/STC holder or the declarant of a declaration of design compliance gives an approved alternative.

(g) Examples of fabrication within the scope of a Part - 145 approval may include but are not limited to the following: (1) fabrication of bushes, sleeves and shims; (2) fabrication of secondary structural elements and skin panels; (3) fabrication of control cables; (4) fabrication of flexible and rigid pipes; (5) fabrication of electrical cable looms and assemblies; (6) formed or machined sheet metal panels for repairs.

All the above - mentioned fabricated parts should be in accordance with the data provided in the overhaul or repair manuals, modification schemes and service bulletins, drawings, or should be otherwise approved by the competent authority.

Note: It is not acceptable to fabricate any item to pattern unless an engineering drawing of the item is produced which includes any necessary fabrication process and which is acceptable to the competent authority.

(h) Where a TC holder or declarant of a declaration of design compliance, or an approved or declared (in accordance with Part 21 Light Subpart G) production organisation, or a production organisation using Part 21 Light Subpart R is prepared to make available complete data which is not referred to in the aircraft manuals or service bulletins but provides manufacturing drawings for items specified in parts lists, the fabrication of these items is not considered to be within the scope of an approval unless ag reed otherwise by the competent authority in accordance with a procedure specified in the exposition .

(i) Inspection and identification Any locally fabricated part should be subject to inspection before, separately, and preferably independently from any inspection of its installation. The inspection should establish full Powered by EASA eRules Page 392 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS compliance with the relevant manufacturing data, and the part should be unambiguously identified as fit for use by stating conformity to the approved or declared (in accordance with Part 21 Light Subpart C) data. Adequate records should be maintained of all such fabrication processes including heat treatment and final inspections. All parts, except those that do not have enough space, should carry a part number which clearly relates it to the manufacturing/i nspection data. In addition to the part’s number, the organisation’s identity should be marked on the part for traceability purposes.

AMC1 145.A.42(c) Components

ED Decision 2019/009/R SEGREGATION OF COMPONENTS (a) Unserviceable components should be identified and stored in a secure location that is under the control of the maintenance organisation until a decision is made on the future status of such components. The organisation that declared the component to be unserviceable may transfer its custody after identifying it as unserviceable to the aircraft owner provided that such transfer is reflected in the aircraft logbook, or engine logbook, or component logbook.

(b) ‘Secure location under the control of an approved maintenance organisation’ refers to a secure location whose security is the responsibility of the approved maintenance organisation. This may include facilities that are established by the organisation at locations different from the main maintenance facilities. These locations should be identified in the relevant procedures of the organisation.

(c) In the case of unsalvageable components, the organisation should: (1) retain such component in the secure location referred to in paragraph (b); (2) arrange for the component to be mutilated in a manner that ensures that they are beyond economic salvage or repair before disposing it; or (3) mark the component indicating that it is unsalvageable, when in agreement with the component owner, the component is disposed of for legitimate non - flight uses (such as training and education aids, research and development), or for non - aviation applica tions, mutilation is often not appropriate. Alternatively to marking, the original part number or data plate information can be removed or a record kept of the disposal of the components.

GM1 145.A.42(c)(i) Components

(b) Mutilation may be accomplished by one or a combination of the following procedures: (1) grinding; (2) burning; Powered by EASA eRules Page 393 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS (3) removal of a major lug or other integral feature; (4) permanent distortion of parts; (5) cutting a hole with cutting torch or saw; (6) melting; (7) sawing into many small pieces; and (8) any other method accepted by the competent authority.

145.A.45 Maintenance data

Regulation (EU) 2021/1963 (a) The organisation shall hold and use applicable current maintenance data which is necessary in the performance of maintenance, including modifications and repairs. “Applicable” means relevant to any aircraft, component or process specified in the organisation’s terms of approval and in any associated capability list.

In the case of maintenance data provided by the person or organisation requesting the maintenance, the organisation shall hold such data when the work is in progress, with the exception of the need to comply with point 145.A.55(a)(3) .

(b) Applicable maintenance data is the data specified in point M.A.401(b) of Annex I (Part - M) or in point ML.A.401(b) of Annex Vb (Part - ML), as applicable.

(c) The organisation shall establish procedures to ensure that if inaccurate, incomplete or ambiguous procedure, practice, information or maintenance instruction is found in the maintenance data used by maintenance personnel, it is recorded as part of the inte rnal safety reporting scheme referred to in point 145.A.202 and notified to the author of the maintenance data.

(d) The organisation may only modify maintenance instructions in accordance with a procedure that is specified in the MOE. With respect to changes to maintenance instructions, the organisation shall demonstrate that they result in equivalent or improved mainte nance standards, and shall inform the author of the maintenance instructions of such changes. For the purposes of this point, “maintenance instructions” mean instructions on how to carry out a particular maintenance task; they exclude the engineering d esign of repairs and modifications.

(e) The organisation shall provide a common work card or worksheet system to be used throughout the relevant parts of the organisation. In addition, the organisation shall either accurately transcribe the maintenance data referred to in points (b) and (d) onto such work cards or worksheets, or make precise reference to the particular maintenance task or tasks contained in Powered by EASA eRules Page 394 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS that maintenance data. Work cards and worksheets may be computer generated and held in an electronic database that is adequately protected against unauthorised alteration, and for which there is a backup electronic database which shall be updated within 24 hours after an entry is made to the main electronic database. Complex or long maintenance tasks shall be transcribed onto the work cards or worksheets and subdivided into clear stages to ensure that there is a record of the accomplishment of the complete maintenance task.

When the organisation provides maintenance services to an aircraft operator which requires its own work card or worksheet system to be used, then such work card or worksheet system may be used. In that case, the organisation shall establish a procedure to ensure that those work cards or worksheets are correctly completed.

(f) The organisation shall ensure that all applicable maintenance data is readily available for use when required by maintenance personnel.

(g) The organisation shall establish a procedure to ensure that maintenance data it controls is kept up to date. In the case of operator/customer controlled and provided maintenance data, the organisation shall be able to show that either it has written co nfirmation from the operator/customer that all such maintenance data is up to date or it has work orders specifying the amendment status of the maintenance data to be used or it can show that it is on the operator/customer maintenance data amendment list.

AMC 1 145.A.45(c) Maintenance data

ED Decision 2022/011/R 1. The referenced procedure should ensure that when maintenance personnel discover inaccurate, incomplete or ambiguous information in the maintenance data , they should record the details as part of the internal safety reporting scheme specified in point 145.A.202 . The procedure should then ensure that the Part - 145 approved maintenance organisation notifies the problem to the author of the maintenance data in a timely manner. A record of such communications to the author of the maintenance data should be retained by the Part - 145 approved organisation until such time as the author of the maintenance data has clarified the issue by e.g. amending the maintenance data.

2. The referenced procedure should be specified in the MOE.

AMC 1 145.A.45(d) Maintenance data

ED Decision 2023/013/R The referenced procedure should address the need for a practical demonstration by the maintenance personnel proposing the change to the compliance monitoring personnel, of the modified maintenance instruction. Depending on the nature of the maintenance instruction modification, a risk assessment may be required to demonstrate that an equiv alent or improved maintenance standard is reached. When satisfied, the compliance monitoring personnel should approve the modified maintenance instruction, and ensure that the author of the maintenance instruction is informed of the modified maintenance instruction. The procedure should include a paper/electronic traceability of the complete process from start to finish, and ensure that the relevant maintenance instruction Powered by EASA eRules Page 395 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS clearly identifies the modification. Modified maintenance instructions should only be used in the following circumstances: (a) Where the original intent of the maintenance instruction can be carried out in a more practical or more efficient manner.

(b) Where the original intent of the maintenance instruction cannot be achieved when following the maintenance instructions. For example, where a component cannot be replaced following the original maintenance instructions.

Important Note: Critical Design Configuration Control Limitations (CDCCL) are airworthiness limitations. Any modification of the maintenance instructions linked to CDCCL constitutes a change to a (restricted) type certificate that should be approved in accordance with Part 21 or Part 21 Light .

AMC 1 145.A.45(e) Maintenance data

ED Decision 2022/011/R 1. ‘The relevant parts of the organisation’ means, as appropriate, aircraft base maintenance, aircraft line maintenance, specialised services, component workshops such as engine workshops, mechanical workshops or avionics workshops. Therefore, a common sys tem should be used, for example, throughout the engine workshops, which may be different from that in the aircraft base maintenance.

2. The work cards should differentiate and specify, when relevant, disassembly, accomplishment of tasks, reassembly and testing as well as the error - capturing method (e.g. independent inspection). In the case of a lengthy maintenance task involving a succe ssion of personnel to complete such a task, it may be necessary to use supplementary work cards or worksheets to indicate what was actually accomplished by each individual person.

3. With reference to point 145.A.65(a) , human factors should be taken into account during the development of work cards and worksheets.

4. ‘Complex or long maintenance tasks’ refers to tasks involving multiple disciplines or multiple shifts, or multiple zones/access opening, special tools, etc., or a combination of these.

The stages into which the work cards are to be subdivided should refer to where work can be interrupted. Subdivision should also indicate when a different discipline continues to work if no separate work cards are provided.

5. Where required by the operator/CAMO/CAO to use their work card or worksheet system, the maintenance organisation should assess the system for compliance with the maintenance organisation procedures, for example, the subdivision of complex or long maintenance tasks.

AMC 145.A.45(f) Maintenance data

AMC 1 145.A.45(g) Maintenance data

ED Decision 2023/013/R To keep data up - to - date, a procedure should be set up to monitor the amendment status of all data and maintain a check that all amendments are being received by being a subscriber to any document amendment scheme. Special attention should be given to mandatory instructions and associated airworthiness limitations published by design approval holders or the declarant of a declaration of design compliance .

145.A.47 Production planning

Regulation (EU) 2021/1963 (a) The organisation shall have a system appropriate to the amount and complexity of work to plan the availability of all necessary personnel, tools, equipment, material, maintenance data and facilities in order to ensure the safe completion of the mainten ance work.

(b) As part of the management system, the planning of maintenance tasks, and the organising of shifts, shall take into account human performance limitations, including the threat of fatigue for maintenance personnel.

(c) When it is required to hand over the continuation or completion of maintenance tasks for reasons of a shift or personnel changeover, relevant information shall be adequately communicated between outgoing and incoming personnel.

(d) The organisation shall ensure that aviation safety hazards associated with external working teams carrying out maintenance at the organisation’s facilities are considered by the organisation’s management system.

AMC 145.A.47(a) Production planning

ED Decision 2016/011/R 1. Depending on the amount and complexity of work generally performed by the maintenance organisation, the planning system may range from a very simple procedure to a complex organisational set - up including a dedicated planning function in support of the p roduction function.

2. For the purpose of Part - 145 , the production planning function includes two complementary elements: − scheduling the maintenance work ahead, to ensure that it will not adversely interfere with other work as regards the availability of all necessary personnel, tools, equipment, material, maintenance data and facilities.

− during maintenance work, organising maintenance teams and shifts and provide all necessary support to ensure the completion of maintenance without undue time pressure.

3. When establishing the production planning procedure, consideration should be given to the following: − logistics, − inventory control, − square meters of accommodation, Powered by EASA eRules Page 397 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS − man - hours estimation, − man - hours availability, − preparation of work, − hangar availability, − environmental conditions (access, lighting standards and cleanliness), − co - ordination with internal and external suppliers, etc.

− scheduling critical maintenance tasks during periods when staff are likely to be most alert.

AMC1 145.A.47(b) Production planning

ED Decision 2022/011/R CONSIDERATION OF FATIGUE IN THE PLANNING OF MAINTENANCE (a) The way and the extent to which the organisation should consider the threat of fatigue in the planning of tasks and organising of shifts will vary from one organisation to another and from one maintenance event to another, depending on what maintenance is to be carried out, how, where, when and by whom.

(b) Fatigue is one example of human factors issues which should be taken into account by the management system, particularly for the planning activity. In this respect, where the organisation activity is prone to fatigue issues, the organisation should: (1) ensure that the safety policy required by point 145.A.200(a) gives due consideration to the aspects of fatigue; (2) ensure that the internal safety reporting scheme required by point 145.A.202 enables the collection of fatigue issues; (3) ensure that the threat of fatigue is adequately taken into account by the management system key processes (e.g. assessment, management, monitoring); (4) provide safety promotion material and adapt safety training accordingly.

(c) The organising of shifts should consider good practices in the maintenance domain and applicable rules. The resulting shift schedule should be shared with the maintenance staff sufficiently in advance so they can plan adequate rest.

The established shift durations should not be exceeded merely for management convenience even when staff is willing to work extended hours.

(d) The organisation should have a procedure (including mitigations) to address cases where the working hours are to be significantly increased, or when the shift pattern is to be significantly modified, such as for urgent operational reasons. In cases not covered by that procedure, the organisation should perform a specific risk assessment and define additional mitigation actions, as applicable. Basic mitigations may include: (1) additional supervision and independent inspection; (2) limitation of maintenance tasks to non - critical tasks; (3) use of additional rest breaks.

GM1 145.A.47(b) Production planning

ED Decision 2022/011/R CONSIDERATION OF FATIGUE IN THE PLANNING OF MAINTENANCE (a) Fatigue may be induced by: (i) the environment and conditions (e.g. noise, humidity, temperature, closed section, working overhead) in which the work is carried out; (ii) excessive hours of duty and shift working, particularly with multiple shift periods or patterns, additional overtime or night work; (iii) travel to the maintenance location (e.g. jetlag, duration) Fatigue is one of the factors that may contribute towards maintenance errors when it is not properly considered as part of planning activities.

(b) Taking into account the threat of fatigue in the planning of maintenance tasks and organising of shifts refers to setting up the maintenance and the shifts in a way that enables the maintenance staff to remain sufficiently free from fatigue so they can perform the planned maintenance safely, including: − providing rest periods of sufficient time to overcome the effects of the previous shift and to be rested by the start of the following shift; − avoiding shift patterns that cause a serious disruption of an established sleep/work pattern, such as alternating day/night duties; − planning recurrent extended rest periods and notifying staff sufficiently in advance.

AMC 145.A.47(c) Production planning

ED Decision 2015/029/R The primary objective of the changeover / handover information is to ensure effective communication at the point of handing over the continuation or completion of maintenance actions. Effective task and shift handover depends on three basic elements: − The outgoing person’s ability to understand and communicate the important elements of the job or task being passed over to the incoming person.

− The incoming person’s ability to understand and assimilate the information being provided by the outgoing person.

− A formalised process for exchanging information between outgoing and incoming persons and a planned shift overlap and a place for such exchanges to take place.

GM1 145.A.47(d) Production planning

ED Decision 2022/011/R ‘External working teams’ refers to an organisation that does not belong to the Part - 145 organisation in whose facility the maintenance is being carrying out, and which is, for example (this list is not exhaustive): − contracted by the Part - 145 maintenance organisation; or − subcontracted by the Part - 145 maintenance organisation; or − contracted by the person or organisation responsible for the aircraft continuing airworthiness.

Powered by EASA eRules Page 399 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS The objective of point 145.A.47(d) is to manage the risk involved in the actual execution of maintenance by the various organisations at the same location.

Example: The need for one organisation to be informed that they should not put the aircraft in a certain configuration (regarding, for instance, electrical power) if this is could contribute to an error in the maintenance performed by another organisation.

Note: Refer to GM2 145.A.205 for the difference between contracting and subcontracting maintenance activities.

Regulation (EU) 2021/1963 (a) The organisation may only carry out maintenance on an aircraft or component for which it is approved when all the necessary facilities, equipment, tooling, material, maintenance data and personnel are available.

(b) The organisation shall be responsible for the maintenance that is performed within the scope of its approval.

(c) The organisation shall ensure that: (1) after the completion of the maintenance, a general verification is carried out to ensure that the aircraft or component is clear of all tools, equipment and any extraneous parts or material, and that all access panels that were removed have been refitted; (2) an error - capturing method is implemented after the performance of any critical maintenance task; (3) the risk of errors during maintenance and the risk of errors being repeated in identical maintenance tasks are minimised; (4) damage is assessed, and modifications and repairs are carried out using the data specified in point M.A.304 of Annex I (Part - M) or point ML.A.304 of Annex Vb (Part - ML), as applicable; (5) the assessment of aircraft defects is carried out in accordance with point M.A.403(b) of Annex I (Part - M) or ML.A.403(b) of Annex Vb (Part - ML), as applicable.

GM 145.A.48 Performance of maintenance

ED Decision 2016/011/R AUTHORISED PERSON An ‘authorised person’ is a person formally authorised by the maintenance organisation to perform or supervise a maintenance task. An ‘authorised person’ is not necessarily ‘certifying staff’.

SIGN - OFF A ‘sign - off’ is a statement issued by the ‘authorised person’ which indicates that the task or group of tasks has been correctly performed. A ‘sign - off’ relates to one step in the maintenance process and is, therefore, different to a certificate of release to service.

AMC1 145.A.48(a) Performance of maintenance

ED Decision 2022/011/R Point (a) of 145.A.48 is intended to cover the situation where the organisation may temporarily not hold all the necessary tools, equipment, material, maintenance data, etc. for an aircraft type or variant, or component specified in the organisation’s scope of work. This point means that the competent authority need not amend the approval to delete the aircraft type or variants, or component on the basis that it is a temporary situation and there is a commitment from the organisation to re - acquire tools, equipment etc. before m aintenance on the related aircraft or component may recommence.

GM1 145.A.48(c) Performance of maintenance

ED Decision 2022/011/R CRITICAL DESIGN CONFIGURATION CONTROL LIMITATIONS (CDCCL) The organisation should ensure that when performing maintenance the CDCCL are not compromised.

The organisation should pay particular attention to possible adverse effects of any change to the wiring of the aircraft, even of a change not specifically assoc iated with the fuel tank system. For example, it should be common practice to identify the segregation of fuel gauging system wiring as a CDCCL. The organisation can prevent adverse effects associated with changes to the wiring by standardising maintenance practices through training, and not through periodic inspections. Training should be prov ided to avoid indiscriminate routing and splicing of wire s and to provide comprehensive knowledge of critical design features of fuel tank systems that would be controlled by a CDCCL.

AMC2 145.A.48( c ) (2) Performance of maintenance

ED Decision 2023/013/R CRITICAL MAINTENANCE TASKS (a ) The procedure should ensure that the following maintenance tasks are reviewed to assess their impact on flight safety: (1) tasks that may affect the control of the aircraft flight path and attitude, such as installation, rigging and adjustments of flight controls; (2) aircraft stability control systems (autopilot, fuel transfer); (3) tasks that may affect the propulsive force of the aircraft, including installation of aircraft engines, propellers and rotors; and (4) overhaul, calibration or rigging of engines, propellers, transmissions and gearboxes.

(b) The procedure should describe which data sources are used to identify critical maintenance tasks. Several data sources may be used, such as: Powered by EASA eRules Page 401 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS (1) information from the design approval holder or the declarant of a declaration of design compliance ; (2) accident reports; (3) investigation and follow - up of incidents; (4) occurrence reporting; (5) flight data analysis, where this is available from the person or organisation responsible for the aircraft continuing airworthiness; (6) results of audits and independent inspections; (7) monitoring schemes for normal operations, where these are available from the person or organisation responsible for the aircraft continuing airworthiness; (8) feedback from training.

AMC3 145.A.48(c)(2) Performance of maintenance

ED Decision 2022/011/R ERROR - CAPTURING METHODS (a) Error - capturing methods are those actions defined by the organisation to detect maintenance errors that are made while performing maintenance.

(b) The organisation should ensure that the error - capturing methods are adequate for the work and the disturbance of the system. A combination of several actions ( e.g. visual inspection, operational check, functional test, rigging check) may be necessary in some cases.

AMC4 145.A.48(c)(2) Performance of maintenance

ED Decision 2022/011/R INDEPENDENT INSPECTION Independent inspection is one possible error - capturing method.

(a) What is an independent inspection An independent inspection is an inspection performed by an ‘independent qualified person’ of a task carried out by an ‘authorised person’, taking into account that: (1) the ‘authorised person’ is the person who performs the task or supervises the task and they assume the full responsibility for the completion of the task in accordance with the applicable maintenance data; (2) the ‘independent qualified person’ is the person who performs the independent inspection and attests the satisfactory completion of the task and that no deficiencies have been found. The ‘independent qualified person’ does not issue a certificate of re lease to service, therefore they are not required to hold certification privileges; (3) the ‘authorised person’ issues the certificate of release to service or signs off the completion of the task after the independent inspection has been carried out satisfactorily; (4) the work card system used by the organisation should record the identification of both persons and the details of the independent inspection as necessary before the certificate of release to service or sign - off for the completion of the task is issued.

Powered by EASA eRules Page 402 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS (b) Qualifications of persons performing independent inspections The organisation should have procedures to demonstrate that the ‘independent qualified person’ has been trained and has gained experience in the specific inspection to be performed.

The organisation could consider making use of, for example: (1) staff holding a certifying staff or support staff or sign - off authorisation or equivalent necessary to release or sign off the critical maintenance task; (2) staff holding a certifying staff or support staff or sign - off authorisation or equivalent necessary to release or sign off similar task in a product of similar category and having received specific practical training in the task to be inspected; or (3) a commander holding a limited certification authorisation in accordance with 145.A.30(j)(4) and having received adequate practical training and having enough experience in the specific task to be inspected and on how to perform independent inspection.

(c) How to perform an independent inspection An independent inspection should ensure correct assembly, locking and sense of operation.

When inspecting control systems that have undergone maintenance, the independent qualified person should consider the following points independently: (1) all those parts of the system that have actually been disconnected or disturbed should be inspected for correct assembly and locking; (2) the system as a whole should be inspected for full and free movement over the complete range; (3) cables should be tensioned correctly with adequate clearance at secondary stops; (4) the operation of the control system as a whole should be observed to ensure that the controls are operating in the correct sense; (5) if different control systems are interconnected so that they affect each other, all the interactions should be checked through the full range of the applicable controls; and (6) software that is part of the critical maintenance task should be checked, for example: version, compatibility with aircraft configuration.

(d) What to do in unforeseen cases when only one person is available REINSPECTION: (1) Reinspection is an error - capturing method subject to the same conditions as an independent inspection is, except that the ‘authorised person’ performing the maintenance task is also acting as ‘independent qualified person’ and performs the inspection.

(2) Reinspection, as an error - capturing method, should only be performed in unforeseen circumstances when only one person is available to carry out the task and perform the independent inspection. The circumstances cannot be considered unforeseen if the pe rson or organisation has not assigned a suitable ‘independent qualified person’ to that particular line station or shift.

Powered by EASA eRules Page 403 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS (3) The certificate of release to service is issued after the task has been performed by the ‘authorised person’ and the reinspection has been carried out satisfactorily. The work card system used by the organisation should record the identification and the details of the reinspection before the certificate of release to service for the task is is sued.

AMC 1 145.A.48(c) (3) Performance of maintenance

ED Decision 2022/011/R The procedures should be aimed at: (a) minimising errors and preventing omissions. Therefore, the procedures should specify: (1) that every maintenance task is signed off only after completion; (2) how the grouping of tasks for the purpose of sign - off allows critical steps to be clearly identified; and (3) that work performed by personnel under supervision (i.e. temporary staff, trainees) is checked and signed off by an authorised person; (b) minimising the possibility of an error being repeated in identical tasks and, therefore, compromising more than one system or function. Thus, the procedures should ensure that no person is required to perform a maintenance task involving removal/instal lation or assembly/disassembly of several components of the same type fitted to more than one system, a failure of which could have an impact on safety, on the same aircraft or component during a particular maintenance check. However, in unforeseen circums tances when only one person is available, the organisation may make use of reinspection as described in point (d) of AMC4 145.A.48(c)(2) .

GM 1 145.A.48(c) (3) Performance of maintenance

ED Decision 2022/011/R To minimise the risk of errors during maintenance and the risk of errors being repeated in identical maintenance tasks, the organisation may implement: − procedures to plan the performance by different persons of the same task in different systems; − independent inspection or re - inspection procedures.

145.A.50 Certification of maintenance

Regulation (EU) 2021/1963 (a) A certificate of release to service shall be issued by appropriately authorised certifying staff on behalf of the organisation when that certifying staff has verified that all the maintenance that was ordered has been properly carried out by the organisati on in accordance with the procedures specified in point 145.A.70 , taking into account the availability and use of the maintenance data specified in point 145.A.45 , and that there are no known non - compliances which endanger flight safety.

(b) A certificate of release to service shall be issued before flight at the completion of any maintenance.

(c) New defects or incomplete maintenance work orders identified during the maintenance shall be brought to the attention of the person or organisation responsible for the aircraft continuing airworthiness for the specific purpose of obtaining agreement to rec tify such defects or Powered by EASA eRules Page 404 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS completing the missing elements of the maintenance work order. In the case where that person or organisation declines to have such maintenance carried out under this point, point (e) is applicable.

(d) A certificate of release to service shall be issued by appropriately authorised certifying staff on behalf of the organisation after the maintenance that was ordered has been carried out on a component whilst it was off the aircraft. The authorised release certificate “EASA Form 1” referred to in Appendix II of Annex I (Part - M) constitutes the component certificate of release to service except if otherwise specified in point M.A.502 of Annex I (Part - M) or ML.A.502 of Annex Vb (Part - ML), as applicable. When an organisation maintains a component for its own use, the EASA Form 1 may not be necessary if the organisation’s internal release procedures in its MOE so provides.

(e) By derogation to point (a), when the organisation is unable to complete all maintenance ordered, it may issue a certificate of release to service within the approved aircraft limitations.

The organisation shall enter such fact in the aircraft certificate of release to service before the issue of such certificate.

(f) By way of derogation from point 145.A.50(a) and point 145.A.42 , when an aircraft is grounded at a location other than the main line station or main maintenance base due to the non - availability of a component with the appropriate release certificate, the organisation contracted for the maintenance of that aircraft may temporarily fit a component without the appropriate release certificate for a maximum of 30 flight hours or until the aircraft first returns to the main line station or main maintenance base, whichever is the sooner, subject to the agreement of the person or organisation responsible for the aircraft’s continuing airworthiness and subject to that component having a suitable release certificate but otherwise in compliance with all applicable maintenance and operational requirements. Such components shall be removed by the time limit provided for in the first sentence of this point unless an appropriate release certificate has been obtained in the meantime under points 145.A.50(a) and 145.A.42 .

AMC 145.A.50 Certification of maintenance after embodiment of a

Standard Change or Standard Repair (SC/SR)

ED Decision 2020/002/R AMC M.A.801 of the AMC to Part - M and AMC1 ML.A.801 of the AMC to Part - ML contain acceptable means of compliance for the release to service of a SC/SR by an organisation approved in accordance with Part - 145 .

GM1 145.A.50(a) Certification of maintenance

ED Decision 2022/011/R ’Endanger flight safety’ means any instances where safe operation could not be assured, or which could lead to an unsafe condition. These typically include, but are not limited to, significant cracking, deformation, corrosion or failure of primary structur e, any evidence of burning, electrical arcing, significant hydraulic fluid or fuel leakage, and any emergency system or total system failure. An airworthiness directive that is overdue for compliance is also considered to be a hazard to flight safety.

However, the intent is not to require the maintenance organisation to find or become responsible for hidden non - compliances which are not expected to be discovered during the ordered maintenance.

A certificate of release to service issued by a maintenance organisation certifies that the performed maintenance work, as agreed in the work order or the contract, has been completed in accordance Powered by EASA eRules Page 405 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS with the applicable requirements and the maintenance organisation’s approved procedures. In the case of aircraft maintenance, it does not necessarily mean that the aircraft is in airworthy condition.

Ensuring that the aircraft is airworthy before each flig ht always remains the responsibility of the person or organisation managing the aircraft continuing airworthiness.

AMC 145.A.50(b) Certification of maintenance

ED Decision 2023/013/R 1. The certificate of release to service should contain the following statement: ‘Certifies that the work specified, except as otherwise specified, was carried out in accordance with Part - 145 and in respect to that work the aircraft/aircraft component is considered ready for release to service’.

Reference should also be made to the EASA Part - 145 approval number and the identity of the person who issued the release .

2. It is acceptable to use an alternate abbreviated certificate of release to service consisting of the following statement ‘ Part - 145 release to service’ instead of the full certification statement specified in paragraph 1. When the alternate abbreviated certificate of release to service is used, the introductory section of the technical log should include an example of the full certifi cation statement from paragraph 1.

3. The certificate of release to service should relate to the task specified in the instructions issued by the (S)TC holder or the declarant of a declaration of design compliance or operator or in the aircraft maintenance programme which itself may cross - refer to maintenance data.

4. The date such maintenance was carried out should include when the maintenance took place relative to any life or overhaul limitation in terms of date/flying hours/cycles/landings etc., as appropriate.

5. When extensive maintenance has been carried out, it is acceptable for the certificate of release to service to summarise the maintenance as long as there is a unique cross - reference to the work package containing full details of maintenance carried out. Dimensional information should be retained in the work - pack record.

AMC1 145.A.50(d) Certification of maintenance

ED Decision 2022/011/R The purpose of the certificate is to certify maintenance work carried out on assemblies/items/components/parts (hereafter referred to as ‘item(s)’). It also allows the removal from aircraft of items in a ‘serviceable’ condition in accordance with AMC2 145.A.50(d) in order to fit them to another aircraft/aircraft component.

The certificate is to be used for export/import purposes, as well as for domestic purposes, and serves as an official certificate for items from the manufacturer/maintenance organisation to users.

It can only be issued by organisations approved by the particular competent authority within the scope of the approval.

The certificate may be used as a rotable tag by utilising the available space on the reverse side of the certificate for any additional information and dispatching the item with two copies of the certificate so that one copy may be eventually returned with the item to the maintenance organisation. The alternative solution is to use existing rotable tags and also supply a copy of the certificate.

In such a case, a clear statement of limitation should be endorsed in Block 12.

A MC2 145.A.50(d) Certification of maintenance

ED Decision 2023/013/R 1. A component which has been maintained off the aircraft needs the issuance of a certificate of release to service for such maintenance and another certificate of release to service in regard to being installed properly on the aircraft when such action occur s.

When an organisation maintains a component for use by the same organisation, an EASA Form 1 may not be necessary depending upon the organisation’s internal release procedures defined in the maintenance organisation exposition.

2. In the case of the issue of EASA Form 1 for components in storage before Part - 145 and Part - 21 became effective and not released on an EASA Form 1 or equivalent in accordance with 145.A.42(a) or removed serviceable from a serviceable aircraft or an aircraft which has been withdrawn from service the following applies: 2.1. An EASA Form 1 may be issued for an aircraft component which has been: − Maintained before Part - 145 became effective or manufactured before Part - 21 became effective.

− Used on an aircraft and removed in a serviceable condition. Examples include leased and loaned aircraft components.

− Removed from aircraft which have been withdrawn from service, or from aircraft which have been involved in abnormal occurrences such as accidents, incidents, heavy landings or lightning strikes.

− Maintained by an unapproved organisation.

2.2. An appropriately rated maintenance organisation approved under Part - 145 may issue an EASA Form 1 as detailed in this AMC subparagraph 2.5 to 2.9, as appropriate, in accordance with procedures detailed in the exposition as approved by the competent authority. The appropriately rated organisation is responsible for ensuring that all reasonable measures have been taken to ensure that only approved and serviceable aircraft components are issued an EASA Form 1 under this paragraph.

2.3. For the purposes of this AMC No 2 only, appropriately rated means an organisation with an approval class rating for the type of component or for the product in which it may be installed.

2.4.2. If the component is unused, when the component was manufactured and by whom with a cross - reference to any original documentation which should be included with the Form.

A list of all airworthiness directives, repairs and modifications known to have been incorporated. If no airworthiness directives or repairs or modifications are known to be incorporated, then this should be so stated.

2.4.4. Detail of life used for life - limited parts and time - controlled components being any combination of fatigue, overhaul or storage life.

2.4.5. For any aircraft component having its own maintenance history record, reference to the particular maintenance history record as long as the record contains the details that would otherwise be required in block 12. The maintenance history record and acceptance test report or statement, if applicable, should be attached to the EASA Form 1 .

2.5. New/unused aircraft components 2.5.1. Any unused aircraft component in storage without an EASA Form 1 up to the effective date(s) for Part - 21 that was manufactured by an organisation acceptable to the competent authority at that time may be issued with an EASA Form 1 by an appropriately rated maintenance organisation approved under Part - 145 . The EASA Form 1 should be issued in accordance with the following subparagraphs which should be included in a procedure within the maintenance organisation manual.

Note 1: It should be understood that the release of a stored but unused aircraft component in accordance with this paragraph represents a maintenance release under Part - 145 and not a production release under Part - 21. It is not intended to bypass the production release procedure agreed by the Member State for parts and subassemblies intended for fitment on the manufacturers’ own production line.

(a) An acceptance test report or statement should be available for all used and unused aircraft components that are subjected to acceptance testing after manufacturing or maintenance as appropriate.

(b) The aircraft component should be inspected for compliance with the manufacturer’s instructions and limitations for storage and condition including any requirement for limited storage life, inhibitors, controlled climate and special storage containers. In addition or in the absence of specific storage instructions the aircraft component should be inspected for damage, corrosion and leakage to ensure good condition.

2.5.2. If it is not possible to establish satisfactory compliance with all applicable conditions specified in subparagraph 2.5.1(a) to (c) inclusive, the aircraft component should be disassembled by an appropriately rated organisation and subjected to a ch eck for incorporated airworthiness directives, repairs and modifications and inspected/tested in accordance with the maintenance data to establish satisfactory condition and, if relevant, all seals, lubricants and life - limited parts should be replaced. Upo n satisfactory completion after reassembly, an EASA Form 1 may be issued stating what was carried out and the reference of the maintenance data included.

Used aircraft components removed from a serviceable aircraft 2.6.1. Serviceable aircraft components removed from a Member State registered aircraft may be issued with an EASA Form 1 by an appropriately rated organisation subject to compliance with this subparagraph.

(a) The organisation should ensure that the component was removed from the aircraft by an appropriately qualified person.

(b) The aircraft component may only be deemed serviceable if the last flight operation with the component fitted revealed no faults on that component/related system.

(c) The aircraft component should be inspected for satisfactory condition including in particular damage, corrosion or leakage and compliance with any additional maintenance data.

(e) A maintenance history record should be available for all used serialised aircraft components.

(f) Compliance with known modifications and repairs should be established.

(g) The flight hours/cycles/landings as applicable of any life - limited parts and time - controlled components including time since overhaul should be established.

(h) Compliance with known applicable airworthiness directives should be established.

2.6.2. Serviceable aircraft components removed from a non - Member State registered aircraft may only be issued with an EASA Form 1 if the components are leased or loaned from the maintenance organisation approved under Part - 145 who retains control of the airworthiness status of the components. An EASA Form 1 may be issued and should contain the information as specified in paragraph 2.4 including the aircraft from which the aircraft component was removed.

2.7. Used aircraft components removed from an aircraft withdrawn from service. Serviceable aircraft components removed from a Member State registered aircraft withdrawn from service may be issued with an EASA Form 1 by a maintenance organisation approved under Part - 145 subject to compliance with this subparagraph.

(a) Aircraft withdrawn from service are sometimes dismantled for spares. This is considered to be a maintenance activity and should be accomplished under the Powered by EASA eRules Page 409 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS control of an organisation approved under Part - 145 , employing procedures approved by the competent authority.

(b) To be eligible for installation, components removed from such aircraft may be issued with an EASA Form 1 by an appropriately rated organisation following a satisfactory assessment.

(c) As a minimum, the assessment will need to satisfy the standards set out in paragraphs 2.5 and 2.6 as appropriate. This should, where known, include the possible need for the alignment of scheduled maintenance that may be necessary to comply with the ma intenance programme applicable to the aircraft on which the component is to be installed.

(d) Irrespective of whether the aircraft holds a certificate of airworthiness or not, the organisation responsible for certifying any removed component should ensure that the manner in which the components were removed and stored are compatible with the st andards required by Part - 145 .

(e) A structured plan should be formulated to control the aircraft disassembly process.

The disassembly is to be carried out by an appropriately rated organisation under the supervision of certifying staff who will ensure that the aircraft components are r emoved and documented in a structured manner in accordance with the appropriate maintenance data and disassembly plan.

(f) All recorded aircraft defects should be reviewed and the possible effects these may have on both normal and standby functions of removed components are to be considered.

(g) Dedicated control documentation is to be used as detailed by the disassembly plan, to facilitate the recording of all maintenance actions and component removals performed during the disassembly process. Components found to be unserviceable are to be id entified as such and quarantined pending a decision on the actions to be taken. Records of the maintenance accomplished to establish serviceability are to form part of the component maintenance history.

(h) Suitable Part - 145 facilities for the removal and storage of removed components are to be used which include suitable environmental conditions, lighting, access equipment, aircraft tooling and storage facilities for the work to be undertaken.

While it may be acceptable for components to be removed, given local environmental conditions, without the benefit of an enclosed facility, subsequent disassembly (if required) and storage of the components should be in accordance with the manufacturer’s recommendations.

2.8. Used aircraft components maintained by organisations not approved in accordance with Part - 145 . For used components maintained by a maintenance organisation not approved under Part - 145 , due care should be taken before acceptance of such components. In such cases an appropriately rated maintenance organisation approved under Part - 145 should establish satisfactory conditions by: (a) dismantling the component for sufficient inspection in accordance with the appropriate maintenance data; (b) replacing all life - limit ed parts and time - controlled components when no satisfactory evidence of life used is available and/or the components are in an unsatisfactory condition; Powered by EASA eRules Page 410 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS (c) reassembling and testing as necessary the component; (d) completing all certification requirements as specified in 145.A.50 .

2.9. Used aircraft components removed from an aircraft involved in an accident or incident.

Such components should only be issued with an EASA Form 1 when processed in accordance with paragraph 2.7 and a specific work order including all additional necessary tests and inspections deemed necessary by the accident or incident. Such a work order may require input from the TC holder or the declarant of a declaration of design compliance or original manufacturer as appropriate. This work order should be referenced in block 12.

AMC 1 145.A.50(e) Certification of maintenance

ED Decision 2023/013/R 1. Being unable to establish full compliance with point 145.A.50(a) means that the maintenance required by the person or organisation responsible for the aircraft continuing airworthiness could not be completed due to either running out of available aircraft maintenance downtime for the scheduled check, or by virtue of th e condition of the aircraft requiring additional maintenance downtime, or because the maintenance data requires a flight to be performed as part of the maintenance, as described in paragraph 4.

2. The person or organisation responsible for the aircraft continuing airworthiness is responsible for ensuring that all required maintenance has been carried out before flight and therefore 145.A.50(e) requires such person or organisation to be informed in the case where full compliance with 145.A.50(a) cannot be achieved within the relevant limitations. If that person Powered by EASA eRules Page 411 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS or organisation agrees to the deferment of full compliance, then the certificate of release to service may be issued subject to details of the deferment, including the competent authority of the State of Registry, being endorsed on the certificate.

Note: Whether or not the person or organisation responsible for the aircraft continuing airworthiness does have the authority to defer maintenance is an issue between that person or organisation and the competent authority of the State of Registry. In case of doubt concerning such a decision, the approved maintenance organisation should inform its competent authority of such doubt, before issuing the certificate of release to service. This will allow this competent authority to investigate the matter with t he competent authority of the State of Registry or the State of the operator as appropriate.

3. The procedure should draw attention to the fact that 145.A.50(a) does not normally permit the issue of a certificate of release to service in the case of non - compliance and should state what action the mechanic, supervisor and certifying staff should take to bring the matter to the attention of the relevant department or person responsible for technical co - ordination with the person or organisation responsible for the aircraft continuing airworthiness so that the issue may be discussed and resolved with that person or organisation. In addition, the appropriate person(s) as specified in point 145.A.30(b) should be kept informed in writing of such possible non - compliance situations and this should be included in the procedure.

4. Certain maintenance data issued by the design approval holder or the declarant of a declaration of design compliance (e.g. aircraft maintenance manual (AMM)) requires that a maintenance task be performed in flight as a necessary condition to complete the maintenance ordered.

Within the aircraft limitations, an appropriately authorised certifying staff should release the incomplete maintenance before the flight on behalf of the maintenance organisation. GM M.A.301(i) or GM1 ML.A.301(f) describe the relations with the aircraft operator, which retains the responsibility for the maintenance check flight (MCF). After performing the flight and any additional maintenance necessary to complete the maintenance ordered, a certificate of release to service should be issued in accordance with 145.A.50(a) .

AMC 1 145.A.50(f) Certification of maintenance

ED Decision 2022/011/R 1. Suitable release certificate means a certificate which clearly states that the aircraft component is serviceable; that clearly specifies the organisation releasing said component together with details of the authority under whose approval the organisati on works including the approval or authorisation reference.

2. ‘Compliance with all applicable maintenance and operational requirements’ means, in particular, making an appropriate entry in the aircraft continuing airworthiness record system or if applicable, in the aircraft technical log system, checking the compatibility of the component with the aircraft approved design , including modifications, repairs, airworthiness directives, life limitations and condition of the aircraft component plus information on where, when and why the aircraft was grounded.

AMC 1 145.A.75(b) Privileges of the organisation

ED Decision 2022/011/R SUBCONTRACTING 1. Working under the management system of an organisation appropriately approved under Part - 145 (subcontracting) refers to the case of one organisation, whether or not it is approved under Part - 145 , that carries out certain maintenance (see paragraph 3.1) under the approval certificate of a Part - 145. In order to subcontract, the Part - 145 organisation should have a procedure for the control of such subcontractors as described below. Any approved maint enance organisation that carries out maintenance under its own approval certificate for another approved maintenance organisation is not considered to be subcontracted for the purpose of this paragraph, but contracted by that other organisation (see GM2 145.A.205 ).

2. Maintenance of engines or engine modules other than ‘a complete workshop maintenance check or overhaul’ is intended to mean any maintenance that can be carried out without disassembly of the core engine or, in the case of modular engines, without disass embly of any core module.

3. FUNDAMENTALS OF SUBCONTRACTING UNDER PART - 145 3.1. The most common reasons for allowing an organisation approved under Part - 145 to sub - contract is to permit acceptance of certain maintenance tasks carried out by subcontractors when approvals by the competent authority of those subcontractors are not justified (e.g. limited scope of work, limited volume of maintenance activities, l imited number of potential customers, limited need in time) or when the subcontractors cannot demonstrate compliance with all elements of the regulation (e.g. no maintenance facilities, specialised staff not covering all maintenance scope).

This subcontracting option permits the acceptance of the following maintenance: (a) specialised maintenance services, such as, but not limited to, surface treatment (e.g. plating, plasma spraying), fabrication of specified parts for repairs/ modifications, welding, etc.; (b) aircraft maintenance (e.g. line maintenance, leaks detection in fuel tanks, special repairs/modifications, complete aircraft painting) up to but not including a complete base maintenance check as specified in point 145.A.75(b) ; (c) component maintenance.; (d) engine maintenance up to but not including a complete workshop maintenance check or overhaul of an engine or engine module as specified in point 145.A.75(b) .

Powered by EASA eRules Page 427 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS 3.2. When maintenance is carried out under the management system of a Part - 145 organisation, it means that for the duration of such maintenance, the Part - 145 approval has been temporarily extended to include the subcontractor. It therefore follows that all parts of the subcontractor (facilities, personnel, equipment and tools, compo nents, maintenance data and procedures) involved with the maintenance organisation’s products undergoing maintenance should meet Part - 145 requirements and the Part - 145 organisation’s MOE for the duration of that maintenance, and it remains the Part - 145 org anisation’s responsibility to ensure such requirements are satisfied.

3.3. When subcontracting, the Part - 145 organisation is not required to have complete facilities for the maintenance that it needs to sub - contract, but it should have its own expertise to determine whether the subcontractor meets the necessary standards. However, a Part - 145 organisation cannot be approved unless it has in - house the facilities, personnel, equipment and tools, components, maintenance data, procedures and expertise to carry out the majority of the maintenance for which it wishes to receive the terms of approval.

3.4. The organisation may find it necessary to include specialised subcontractors to enable it to be approved to issue the certificate of release to service of a particular maintenance. Examples are provided in point 3.1(a). To authorise the use of such subcontractors, the competent authority will need to be satisfied that the Part - 145 organisation has the necessary expertise and procedures to control such subcontractors.

3.5. A maintenance organisation working outside the scope of its terms of approval is deemed to be not approved for the work considered. Such an organisation may in this circumstance operate only as a subcontractor under the management system and control of anot her organisation appropriately approved under Part - 145 .

3.6. Authorisation to sub - contract is indicated by the competent authority approving the MOE containing a specific procedure on the control of subcontractors as well as a list of subcontractors.

4. PART - 145 PROCEDURES FOR THE CONTROL OF SUBCONTRACTORS 4.1. A pre - audit procedure should be established whereby the Part - 145 organisation should audit a prospective subcontractor to determine whether those services of the subcontractor that it wishes to use meet the intent of Part - 145. This audit should be performed under the responsibility of the compliance monitoring function .

4 .2. The Part - 145 organisation needs to assess to what extent it will use the subcontractor resources (facilities included). The contract between the Part - 145 organisation and the subcontractor will determine whether the Part - 145 organisation requires its own paperwork, ma intenance data and components to be used or, provided that they meet the requirements of Part - 145, if the facilities, equipment and tools from the subcontractor will be used. In the case of subcontractors who provide specialised services, it may for pract ical reasons be necessary to use their specialised services paperwork, maintenance data and components, subject to acceptance by the Part - 145 organisation.

4.3. Unless the sub - contracted maintenance work can be fully inspected on receipt by the Part - 145 organisation, it will be necessary for the Part - 145 organisation to establish an MOE procedure to control the subcontracted maintenance work (and associated supporting documents). The organisation will need to consider whether to use its own personnel or to authorise the subcontractor personnel for that control.

The certificate of release to service may be issued either by subcontractor staff holding a certification authorisation issued by the Part - 145 organisation in accordance with points 145.A.30 and 145.A.35 as appropriate, or by the Part - 145 organisation certifying staff.

4.5. The subcontractor control procedure will need to address the relevant management system key processes such as safety risk management and compliance monitoring (see point 145.A.205 ). The procedure should ensure that records of all subcontractor audits and inspections, and the corresponding actions are kept, and provide information on when subcontractors are used. The procedure should include a clear revocation process for subcontrac tors that do not meet the Part - 145 maintenance organisation’s requirements.

4 .6. The Part - 145 compliance monitoring staff will need to audit the subcontractor control function of the Part - 145 organisation and to audit the subcontractors unless this task is already carried out by the subcontractor control function on behalf of the compliance monito ring function.

4.7. The contract between the Part - 145 organisation and the subcontractor should contain a provision to ensure that access to the subcontractor is granted to any person authorised by the authorities specified in point 145.A.140 .

GM1 145.A.95 Findings and observations

ED Decision 2022/011/R ROOT CAUSE ANALYSIS (a) It is important that the analysis does not primarily focus on establishing who or what caused the non - compliance, but on why it was caused. Establishing the root cause(s) often requires an overarching view of the events and circumstances that led to i t, to identify all the possible systemic and contributing factors (regulatory, technical, human factors, organisational factors, etc.) in addition to the direct factors.

(b) A narrow focus on single events or failures, or the use of a simple, linear model, such as a fault tree, to identify the chain of events that led to the non - compliance, may not properly reflect the complexity of the issue, and therefore there is a ris k that important factors that must be addressed in order to prevent a reoccurrence will be ignored.

Such an inappropriate or partial root cause analysis often leads to defining ‘quick fixes’ that only address the symptoms of the non - conformity. A peer review of the results of the root cause analysis may increase its reliability and objectivity.

145.A.120 Means of compliance

Regulation (EU) 2021/1963 (a) An organisation may use any alternative means of compliance to establish compliance with this Regulation.

(b) If an organisation wishes to use an alternative means of compliance, it shall, prior to using it, provide the competent authority with a full description. The description shall include any revisions to manuals or procedures that may be relevant, as well as an explanation indicating how compl iance with this Regulation is achieved.

The organisation may use those alternative means of compliance subject to prior approval from the competent authority.

GM1 145.A.120 Means of compliance

ED Decision 2022/011/R GENERAL (a) Acceptable means of compliance (AMC), as referred to in Article 76(3) of Regulation (EU) 2018/1139, are a tool to standardise the demonstration of compliance and facilitate the verification activities of the competent authorities with Regulation (EU) 2 018/1139 and its delegated and implementing acts. They are published by the Agency to achieve these objectives. Whereas the competent authorities and the regulated entities are not legally bound to use them, applying them is recommended.

(b) If an organisation wishes to use means to comply with the Regulation different from the AMC established by EASA, that organisation may need to demonstrate compliance with Regulation (EU) 2018/1139 and its delegated and implementing acts by using alternative means of compliance (AltMoC): (1) established by its competent authority — see GM1 145.B.120 ; or (2) established by that organisation and approved by its competent authority — see point (c) below.

Powered by EASA eRules Page 433 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS An AltMoC does not allow deviation from Regulation (EU) 2018/1139 and its delegated or implementing acts.

(c) AltMoC established by an organisation and approved by its competent authority: An organisation wishing to use a different means of compliance than the one published by the Agency, can propose and implement an AltMoC only once the competent authority approves it.

In this case, the organisation is responsible for demonstrating how that AltMoC establishes compliance with the Regulation.

This approval will be granted by its competent authority on an individual basis and restricted to that specific applicant. Other organisations wishing to use the same means of compliance should follow the AltMoC process (demonstrating compliance with the R egulation) and obtain individual approval from their competent authority.

GM2 145.A.120 Means of Compliance

ED Decision 2022/011/R WHEN AN ALTERNATIVE MEANS OF COMPLIANCE IS NEEDED When there is no EASA AMC for a certain requirement in the Regulation, the means of compliance proposed by the organisation to that point of the Regulation do not need to go through the AltMoC process. It is the responsibility of the competent authority to verify that compliance with the Regulation is met. However, in certain cases the organisation may propose, and the competent authority may agree, to have such means of compliance follow the AltMoC process.

When there is an EASA AMC, the AltMoC process is needed in the following (not exhaustive) cases: − a means to comply with the Regulation is technically different in character to the AMC published by EASA; − A Form is significantly different from the one proposed in the EASA AMC.

Note: A Form required by the delegated and implementing acts cannot be changed.

Examples of issues not considered to require an AltMoC process include, but are not limited to: − editorial changes to an EASA AMC, as long as it does not change the intent of the AMC; — transposing an EASA AMC into the organisational structure, organisational processes, or standard operating procedures with different wording and terminology customised to the organisation’s environment, if this does not change the intent of the AMC and its associated level of safety.

GM1 145.A.200 Management system

ED Decision 2022/011/R GENERAL Safety management seeks to proactively identify hazards and to mitigate the related safety risks before they result in aviation accidents and incidents. Safety management enables an organisation to manage its activities in a more systematic and focused man ner. When an organisation has a clear understanding of its role and contribution to aviation safety, it can prioritise safety risks and more effectively manage their resources and obtain optimal results.

The principles of the requirements in points 145.A.200 , 145.A.202 , 145.A.205 and the related AMC constitute the EU management system framework for aviation safety management. This framework addresses the core elements of the ICAO safety management system (SMS) framework defined in Appendix 2 to Annex 19, includes the elements of t he compliance monitoring system, and promotes an integrated approach to the management of an organisation. It facilitates the introduction of the additional safety management components, building upon the existing management system, rather than adding them as a separate framework.

This approach is intended to encourage organisations to embed safety management and risk - based decision - making into all their activities, instead of superimposing another system onto their existing management system and governance structure. In addition, i f the organisation holds multiple organisation certificates within the scope of Regulation (EU) 2018/1139, it may choose to implement a single management system to cover all of its activities. An integrated management system may not only be used to capture management system requirements resulting from Regulation (EU) 2018/1139, but also could cover other regulatory frameworks requiring compliance with Annex 19 or other business management systems such as security, occupational health and environmental manag ement systems. Integration will remove any duplication and exploit synergies by managing safety risks across multiple activities. Organisations may determine the best means to structure their management systems to suit their business and organisational nee ds.

The core part of the management system framework ( 145.A.200 ) focuses on what is essential to manage safety, by mandating the organisation to: (a) clearly define accountabilities and responsibilities; (b) establish a safety policy and the related safety objectives; (c) implement safety reporting procedures in line with just culture principles; (d) ensure the identification of aviation safety hazards entailed by its activities, ensure their evaluation, and the management of the associated risks, including: (1) taking actions to mitigate the risks; (2) verifying the effectiveness of the actions taken to mitigate the risks; (e) monitor compliance, while considering any additional requirements that are applicable to the organisation; Powered by EASA eRules Page 436 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS (f) keep their personnel trained, competent, and informed about significant safety issues; and (g) document all the key management system processes.

Compared with the previous Part - 145 quality system ‘framework’ (now covered by point (b) and (e)), the new elements that are introduced by the management system are, in particular, those addressed under points (c) and (d).

Points (a), (b) and (g) address component 1 ‘Safety policy and objectives’ of the ICAO SMS framework.

Points (c) and (d)(1) address component 2 ‘Safety Risk Management’ of the ICAO SMS framework.

Point (d)(2) addresses component 3 ‘Safety Assurance’ of the ICAO SMS framework. Finally, point (f) addresses component 4 ‘Safety Promotion’ of the ICAO SMS framework.

Point 145.A.200 introduces the following as key safety management processes; these are further specified in the related AMC and GM: − Hazard identification; − Safety risk management; − Internal investigation; − Safety performance monitoring and measurement; − Management of change; − Continuous improvement; − Immediate safety action and coordination with the aircraft operator’s Emergency Response Plan (ERP).

It is important to recognise that safety management will be a continuous activity, as hazards, risks and the effectiveness of safety risk mitigations will change over time.

These key safety management processes are supported by a compliance monitoring function as an integral part of the management system. Most aviation safety regulations constitute generic safety risk controls established by the ‘regulator’. Therefore, ensuri ng effective compliance with the regulations during daily operations and independent monitoring of compliance are fundamental to any management system for safety. The compliance monitoring function may, in addition, support the follow - up of safety risk mit igation actions. Moreover, where non - compliances are identified through internal audits, the causes will be thoroughly assessed and analysed. Such an analysis in return supports the risk management process by providing insights into causal and contributing factors, including human factors, organisational factors and the environment in which the organisation operates. In this way, the outputs of compliance monitoring become some of the various inputs to the safety risk management functions. Conversely, the o utput of the safety risk management processes may be used to determine focus areas for compliance monitoring. In this way, internal audits will inform the organisation’s management of the level of compliance within the organisation, whether safety risk mit igation actions have been implemented, and where corrective or preventive action is required. The combination of safety risk management and compliance monitoring should lead to an enhanced understanding of the end - to - end process and the process interfaces, exposing opportunities for increased efficiencies, which are not limited to safety aspects.

As aviation is a complex system with many organisations and individuals interacting together, the primary focus of the key safety management processes is on the organisational processes and procedures, but it also relies on the humans in the system. The or ganisation and the way in which it operates can have a significant impact on human performance. Therefore, safety management Powered by EASA eRules Page 437 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS necessarily addresses how humans can contribute both positively and negatively to an organisation’s safety outcomes, recognising that human behaviour is influenced by the organisational environment.

The effectiveness of safety management largely depends on the degree of commitment of the senior management to create a working environment that optimises human performance and encourages personnel to actively engage in and contribute to the organisation’s management processes. Similarly, a positive safety culture relies on a high degree of trust and respect between the personnel and the management, and it must therefore be created and supported at the senior management level. If the management does not tre at individuals who identify hazards and report adverse events in a consistently fair and just way, those individuals are unlikely to be willing to communicate safety issues or to work with the management to effectively address the safety risks. As with tru st, a positive safety culture takes time and effort to establish, and it can be easily lost.

It is further recognised that the introduction of processes for hazard identification and risk assessment, mitigation and verification of the effectiveness of such mitigation actions will create immediate and direct costs, while related benefits are someti mes intangible, and may take time to materialise. Over time, an effective management system will not only address the risks of major occurrences, but also identify and address production inefficiencies, improve communication, foster a better organisational culture, and lead to a more effective control of contractors and suppliers. In addition, through an improved relationship with the authority, an effective management system may result in a reduced oversight burden.

Thus, by viewing safety management and the related organisational policies and key processes as items that are implemented not only to prevent incidents and accidents, but also to meet the organisation’s strategic objectives, any investment in safety shoul d be seen as an investment in productivity and organisational success.

AMC1 145.A.200(a)(1) Management system

ED Decision 2022/011/R ORGANISATION AND ACCOUNTABILITIES (a) The management system should encompass safety by including a safety manager and a safety review board in the organisational structure. The functions of the safety manager are those defined in AMC1 145.A.30(c);(ca) .

(b) Safety review board (1) The safety review board should be a high - level committee that considers matters of strategic safety in support of the accountable manager’s safety accountability.

(2) The board should be chaired by the accountable manager and composed of the person or group of persons nominated under points 145.A.30 .

(3) The safety review board should monitor: (i) the safety performance against the safety policy and objectives; (ii) that any safety action is taken in a timely manner; and (iii) the effectiveness of the organisation’s management system processes.

(4) The safety review board may also be tasked with: (i) reviewing the results of compliance monitoring; (ii) monitoring the implementation of related corrective and preventive actions.

(d) Notwithstanding point (a), where justified by the size of the organisation and the nature and complexity of its activities and subject to a risk assessment and agreement by the competent authority, the organisation may not need to establish a formal sa fety review board. In this case, the tasks normally allocated to the safety review board should be allocated to the safety manager.

GM1 145.A.200(a)(1) Management system

ED Decision 2022/011/R SAFETY ACTION GROUP (a) Depending on the size of the organisation and the nature and complexity of its activities, a safety action group may be established as a standing group or as an ad hoc group to assist, or act on behalf of the safety manager or the safety review board.

(b) More than one safety action group may be established, depending on the scope of the task and the specific expertise required.

(c) The safety action group usually reports to, and takes strategic direction from, the safety review board, and may be composed of managers, supervisors and personnel from operational areas.

(d) The safety action group may be tasked or assist with: (1) monitoring safety performance; (2) defining actions to control risks to an acceptable level; (3) assessing the impact of organisational changes on safety; (4) ensuring that safety actions are implemented within the agreed timescales; (5) reviewing the effectiveness of previous safety actions and safety promotion.

GM2 145.A.200(a)(1) Management system

ED Decision 2022/011/R MEANING OF THE TERMS ‘ACCOUNTABILITY’ AND ‘RESPONSIBILITY’ In the English language, the notion of accountability is different from the notion of responsibility.

Whereas ‘accountability’ refers to an obligation which cannot be delegated, ‘responsibility’ refers to an obligation that can be delegated.

AMC1 145.A.200(a)(2) Management system

ED Decision 2022/011/R SAFETY POLICY AND OBJECTIVES (a) The safety policy should: (1) reflect organisational commitments regarding safety, and its proactive and systematic management, including the promotion of a positive safety culture; (2) include internal reporting principles, and encourage personnel to report maintenance - related errors, incidents and hazards; Powered by EASA eRules Page 439 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS (3) recognise the need for all personnel to cooperate with the compliance monitoring and internal investigations referred to under point (c) of AMC1 145.A.200(a)(3) ; (4) be endorsed by the accountable manager; (5) be communicated, with visible endorsement, throughout the organisation; and (6) be periodically reviewed to ensure it remains relevant and appropriate for the organisation.

(b) The safety policy should include a commitment to: (1) comply with all the applicable legislation, to meet all the applicable requirements, and adopt practices to improve safety standards; (2) provide the necessary resources for the implementation of the safety policy; (3) apply human factors principles, including giving due consideration to the aspect of fatigue; (4) enforce safety as a primary responsibility of all managers; and (5) apply ‘just culture’ principles to internal safety reporting and the investigation of occurrences and, in particular, not to make available or use the information on occurrences: (i) to attribute blame or liability to front - line personnel or other persons for actions, omissions or decisions taken by them that are commensurate with their experience and training; or (ii) for any purpose other than maintaining or improving aviation safety.

(c) Senior management should continually promote the safety policy to all personnel, demonstrate its commitment to it, and provide necessary human and financial resources for its implementation.

(d) Taking due account of its safety policy, the organisation should define safety objectives. The safety objectives should: (1) form the basis for safety performance monitoring and measurement; (2) reflect the organisation’s commitment to maintain or continuously improve the overall effectiveness of the management system; (3) be communicated throughout the organisation; and (4) be periodically reviewed to ensure they remain relevant and appropriate for the organisation.

GM1 145.A.200(a)(2) Management system

ED Decision 2022/011/R SAFETY POLICY (a) The safety policy is the means whereby the organisation states its intention to maintain and, where practicable, improve safety levels in all its activities and to minimise its contribution to the risk of an aircraft accident or serious incident as far as is reasonably practicable. It reflects the management’s commitment to safety, and should reflect the organisation’s philosophy of safety management, as well as being the foundation on which the organisation’s management Powered by EASA eRules Page 440 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS system is built. It serves as a reminder of ‘how we do business here’. The creation of a positive safety culture begins with the issuance of a clear, unequivocal policy.

(b) The commitment to apply ‘just culture’ principles forms the basis for the organisation’s internal rules describing how ‘just culture’ principles are guaranteed and implemented.

(c) For organisations that have their principal place of business in a Member State, Regulation (EU) No 376/2014 defines the ‘just culture’ principles to be applied (refer in particular to Article 16(11) of that Regulation).

AMC1 145.A.200(a)(3) Management system

ED Decision 2023/013/R SAFETY MANAGEMENT KEY PROCESSES (a) Hazard identification processes (1) A reporting scheme should be the formal means of collecting, recording, analysing, acting on, and generating feedback about hazards, events and the associated risks that may affect safety.

(2) The hazards identification should include in particular: (i) hazards that may be linked to human factors issues that affect human performance; and (ii) hazards that may stem from the organisational set - up or the existence of complex operational and maintenance arrangements (such as when multiple organisations are contracted, or when multiple levels of contracting/subcontracting are included).

(b) Risk management processes (1) A formal safety risk management process should be developed and maintained that ensures reactive, proactive and predictive approach composed by: (i) analysis (e.g. in terms of the probability and severity of the consequences of hazards and occurrences); (ii) assessment (in terms of tolerability); (iii) control (in terms of mitigation) of risks to an acceptable level.

Note: The severity of the consequence should be evaluated to the best knowledge and engineering judgement of the organisation, and this evaluation may require collecting information from the competent authority, incident/accident investigation reports, the design approval holder , the declarant of a declaration of design compliance, etc.

(2) The levels of management who have the authority to make decisions regarding the tolerability of safety risks, in accordance with (b)(1)(ii), should be specified.

(c) Internal investigation (1) In line with its just culture policy, the organisation should define how to investigate incidents such as errors or near misses, in order to understand not only what happened, but also how it happened, to prevent or reduce the probability and/or conseq uence of future recurrences (refer to AMC1 145.A.202 ). This approach should avoid concentrating the analysis on who was (were) directly or indirectly concerned by the events.

(d) Safety performance monitoring and measurement (1) Safety performance monitoring and measurement should be the processes by which the safety performance of the organisation is verified in comparison with the safety policy and the safety objectives.

(2) These processes may include, as appropriate to the size, nature and complexity of the organisation: (i) safety reporting, which may also address the status of compliance with the applicable requirements; (ii) safety reviews, including trend reviews, which would be conducted during the introduction of new products and their components, new equipment/technologies, the implementation of new or changed procedures, or in situations of organisational changes that may have an impact on safety; (iii) safety audits that focus on the integrity of the organisation’s management system, and on periodically assessing the status of safety risk controls; (iv) safety surveys, examining particular elements or procedures in a specific area, such as identified problem areas, or bottlenecks in daily maintenance activities, perceptions and opinions of maintenance management personnel, and areas of dissent or con fusion; and (v) other indicators relevant to safety performance, which may be generated by automated means.

(e) Management of change Changes may introduce new hazards or threaten existing safety risk controls. The management of change should be a documented process established by the organisation to identify external and internal changes that may have an adverse effect on the safety of its maintenance activities.

It should make use of the organisation’s existing hazard identification, risk assessment and mitigation processes.

(f) Continuous improvement The organisation should continuously seek to improve its safety performance and the effectiveness of its management system. Continuous improvement may be achieved through: (1) audits carried out by external organisations; (2) assessments, including assessments of the effectiveness of the safety culture and management system, in particular to assess the effectiveness of the safety risk management processes; (3) staff surveys, including cultural surveys, that can provide useful feedback on how engaged personnel are with the management system; (4) monitoring the recurrence of incidents and occurrences; (5) evaluation of safety performance indicators and reviews of all the available safety performance information; and (6) the identification of lessons learned.

These provisions are without prejudice to the occurrence reporting required by point 145.A.60 .

(2) If applicable, procedures should be implemented to enable the organisation to react promptly if the ERP is triggered by the operator and it requires the support of the Part - 145 organisation.

GM1 145.A.200(a)(3) Management system

ED Decision 2022/011/R SAFETY RISK MANAGEMENT — INTERFACES BETWEEN ORGANISATIONS (a) Safety risk management processes should specifically address the planned implementation of, or participation of the organisation in, complex operational and maintenance arrangements (such as when multiple organisations are contracted, or when multiple levels of contracting/subcontracting are included).

(b) Hazard identification and risk assessment start with the identification of all the parties involved in the arrangement, including independent experts and non - approved organisations. This identification process extends to cover the overall control struc ture, and assesses in particular the following elements across all subcontract levels and all parties within such arrangements: (1) coordination and interfaces between the different parties; (2) applicable procedures; (3) communication between all the parties involved, including reporting and feedback channels; (4) task allocation, responsibilities and authorities; and (5) the qualifications and competency of key personnel with reference to point 145.A.30.

(c) Safety risk management should focus on ensuring the following aspects: (1) clear assignment of accountability and allocation of responsibilities; (2) that only one party is responsible for a specific aspect of the arrangement, with no overlapping or conflicting responsibilities, in order to eliminate coordination errors; (3) the existence of clear reporting lines, both for occurrence reporting and progress reporting; (4) the possibility for staff to directly notify the organisation of any hazard that suggests an obviously unacceptable safety risk as a result of the potential consequences of this hazard.

(d) The safety risk management processes should ensure that there is regular communication between all the parties involved to discuss work progress, risk mitigation actions, and changes to the arrangements, as well as any other significant issues.

GM2 145.A.200(a)(3) Management system

ED Decision 2022/011/R MANAGEMENT OF CHANGE (a) Unless they are properly managed, changes in organisational structure, facilities, the scope of work, personnel, documentation, policies and procedures, etc. can result in the inadvertent introduction of new hazards, and expose the organisation to new or increased risks. Effective organisations seek to improve their processes, with conscious recognition that changes can expose the organisation to potentially latent hazards and risks if they are not properly and effectively managed.

(b) Regardless of the magnitude of a change, large or small, its safety implications should always be proactively considered. This is primarily the responsibility of the team that proposes and/or implements the change. However, a change can only be successfully implemented if all the personnel affected by the change are engaged, are involved and participate in the process. The magnitude of a change, its safety criticality, and its potential impact on human performance should be assessed in any change management process.

(c) The process for the management of change typically provides principles and a structured framework for managing all aspects of the change. Disciplined application of the management of change can maximise the effectiveness of the change, engage the staff , and minimise the risks that are inherent in a change.

(d) The introduction of a change is the trigger for the organisation to perform their hazard identification and risk management processes.

Some examples of change include, but are not limited to: (1) changes to the organisational structure; (2) the inclusion of a new aircraft type in the terms of approval; (3) the addition of aircraft of the same or a similar type; (4) significant changes in personnel (affecting key personnel and/or large numbers of personnel, high turnover); (5) new or amended regulations; (6) changes to the security arrangements; (7) changes in the economic situation of an organisation (e.g. commercial or financial pressure); (8) new schedule(s), location(s), equipment, and/or operational procedures; and (9) the addition of new subcontractors.

(e) A change may have the potential to introduce new, or to exacerbate pre - existing, human factors issues. For example, changes in computer systems, equipment, technology, personnel changes, including changes in management personnel, procedures, work organisat ion, or work processes are likely to affect performance.

(f) The purpose of integrating human factors (HF) into the management of change is to minimise potential risks by specifically considering the impact of the change on the people within a system.

In addition, the activities utilised to manage these issues should be integrated into the change management plan.

(h) Effective management of change should be supported by the following: (1) implementation of a process for formal hazard identification/risk assessment for major operational changes, major organisational changes, changes in key personnel, and changes that may affect the way maintenance is carried out; (2) identification of changes that are likely to occur in business which would have a noticeable impact on: (i) resources — material and human; (ii) management direction — policies, processes, procedures, training; and (iii) management control; (3) safety cases/risk assessments that are focused on aviation safety; (4) the involvement of key stakeholders in the change management process, as appropriate.

(i) During the management of change process, previous risk assessments and existing hazards are reviewed for possible effect.

ED Decision 2022/011/R MANAGEMENT SYSTEM DOCUMENTATION (a) The organisation may document its safety policy, safety objectives and all its key management system processes in a separate manual (e.g. a Safety Management Manual or Management System Manual), or in its MOE (see AMC1 145.A.70(a) , Part 3 ‘Management system procedures’). Organisations that hold multiple organisation certificates within the scope of Regulation (EU) 2018/1139 may prefer to use a separate manual in order to avoid duplication.

That manual or the MOE, depending on the c ase, should be the key instrument for communicating the approach to the management system for the whole of the organisation.

(b) The organisation may also choose to document some of the information that is required to be documented in separate documents (e.g. policy documents, procedures). In that case, it should ensure that the manual or the MOE contains adequate references to any document that is kept separately. Any such documents are to be considered to be integral parts of the organisation’s management system documentation.

It should include a percentage of unannounced audits carried out on a sample basis while maintenance is being carried out. This means that some audits should be carried out during the night for those organisations that work at night.

(d) The organisation should establish an audit plan to show when and how often the activities as required by this Regulation will be audited.

(e) Except as specified in points (h) and (j), the audit plan should ensure that all aspects of Part - 145 compliance are verified every year, including all the subcontracted activities. The auditing may be carried out as a complete single exercise or subdivided over the annual period. The independent audit should not require each procedure to be verified agai nst each product line when it can be shown that the particular procedure is common to more than one product line and the procedure has been verified every year without resultant findings. Where findings have been identified, compliance with the particular procedure should be verified against other product lines until the findings have been closed, after which the independent audit procedure may revert back to a yearly interval for the particular procedure.

(f) Except as specified otherwise in point (h), the independent audit should sample check one product (such as one aircraft or engine or component) while undergoing maintenance on each product line every year as a demonstration of compliance with the maint enance procedures and requirements associated with that specific product. This should include in particular the verification of: − the maintenance data and compliance with the organisation procedures, including consideration of human factors issues; − the facility and maintenance environment; − the standard of inspection and precautions; − the completion of work cards/worksheet; − the tools and material; − the authorisation of the person carrying out maintenance.

For the purpose of this AMC, a product line includes any product under an Appendix II approval class rating as specified in the terms of approval issued to the particular organisation.

It therefore follows, for example, that a Part - 145 maintenance organisation approved to maintain aircraft, engines, brakes and autopilots would need to carry out at least four complete product audits each year, except as specified otherwise in points (f), (h) or (j).

(g) The product audit includes witnessing any relevant testing and visually inspecting the product and the associated documentation. The product audit should not involve repeated disassembly or testing unless the product audit identifies findings that requ ire such an action.

(h) Except as specified otherwise in point (j), where the organisation contracts the independent audit element of the compliance monitoring function in accordance with point (l), the audit should be carried out twice every year.

(i) Except as specified otherwise in point (j), where the organisation has line stations listed as per point 145.A.75(d) , the compliance monitoring documentation should include a description of how these line stations are integrated into the monitoring and include a plan to audit each listed line station at a frequency consistent with the extent of flight activity at the pa rticular line Powered by EASA eRules Page 447 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS station and the related safety hazards identified. Except as specified otherwise in point (j), the maximum period between audits of a particular line station should not exceed 2 years.

(j) Except as specified otherwise in point (f), provided that there are no safety - related findings, the audit planning cycle specified in this AMC may be increased by up to 100 %, subject to a risk assessment and/or mitigation actions, and agreement by the competent authority.

(k) A report should be issued each time an audit is carried out describing what was checked and the resulting non - compliance findings against applicable requirement and procedures.

(l) Organisations with a maximum of 10 maintenance staff actively engaged in carrying out maintenance may subcontract the whole independent audit element of the compliance monitoring function to another organisation or contract a qualified and competent pe rson to become responsible for this element, with the agreement of the competent authority.

This does not prevent a larger organisation from occasionally using external support for conducting particular audits.

AMC3 145.A.200(a)(6) Management system

ED Decision 2022/011/R COMPLIANCE MONITORING — CONTRACTING OF THE INDEPENDENT AUDIT (a) If external personnel are used to perform independent audits: (1) any such audits should be performed under the responsibility of the compliance monitoring manager; and (2) the organisation remains responsible for ensuring that the external personnel have the relevant knowledge, background, and experience that are appropriate to the activities being audited, including knowledge and experience in compliance monitoring.

(b) The organisation retains the ultimate responsibility for the effectiveness of the compliance monitoring function, in particular for the effective implementation and follow - up of all corrective actions.

AMC4 145.A.200(a)(6) Management system

ED Decision 2022/011/R COMPLIANCE MONITORING — FEEDBACK SYSTEM (a) Another essential element of the compliance monitoring function is the feedback system.

(b) The feedback system should not be contracted to external persons or organisations.

(c) When a non - compliance is found, the compliance monitoring function should ensure that the root cause(s) and contributing factor(s) are identified (see GM1 145.A.95 ), and that corrective actions are defined. The feedback part of the compliance monitoring function should define who is required to address any non - compliance in each particular case, and the procedure to be followed if the corrective action is not comple ted within the defined time frame. The principal functions of the feedback system are to ensure that all findings resulting from the independent audits of the organisation are properly investigated and corrected in a timely manner, and to enable the accoun table manager to be kept informed of safety issues and the extent of compliance with Part - 145 .

Powered by EASA eRules Page 448 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS (d) The independent audit reports referred to in AMC2 145.A.200(a)(6) should be sent to the relevant department(s) for corrective action, giving target closure dates. These target dates should be discussed with the relevant department(s) before the compliance monitoring function confirms the dates in the report. The relevan t department(s) is (are) required to implement the corrective action and inform the compliance monitoring function of the status of the implementation of the action.

(e) Unless the review of the results from compliance monitoring is given to the safety review board (ref. AMC1 145.A.200(a)(1) point (b)(4)), the accountable manager should hold regular meetings with staff to check the progress of corrective actions. These meetings may be delegated to the compliance monitoring manager on a day - to - day basis, provided that the accountable manager: (1) meets the senior staff involved at least twice per year to review the overall performance of the compliance monitoring function; and (2) receives at least a half - yearly summary report on non - compliance findings.

(f) All records pertaining to the independent audit and the feedback system should be retained for the period specified in point 145.A.55(c) or for such periods as to support changes to the audit planning cycle in accordance with AMC2 145.A.200(a)(6) , whichever is the longer.

GM1 145.A.200(a)(6) Management system

ED Decision 2022/011/R COMPLIANCE MONITORING FUNCTION The compliance monitoring function is one of the elements that is required to be in compliance with the applicable requirements. This means that the compliance monitoring function itself should be subject to independent monitoring of compliance in accordance with 145.A.200(a)(6) .

GM2 145.A.200(a)(6) Management system

ED Decision 2022/011/R COMPLIANCE MONITORING — AUDIT PLAN (a) The purpose of this GM is to provide guidance on one acceptable working audit plan to meet part of the needs of point 145.A.200(a)(6) . There is any number of other acceptable working audit plans.

(b) The audits described in the audit plan are intended to monitor compliance with the applicable requirements, and at the same time to review all areas of the organisation to which those requirements are applicable.

(c) In order to achieve this objective, as a first element, the organisation needs to identify all the regulatory requirements that are applicable to the activity and the scope of work under consideration, to allow the audit plan to focus on the relevant t opics. Each topic (e.g. facilities, personnel, etc.) should be cross - referred with the relevant requirement and the related procedure of the organisation in the exposition that describes the particular topic. If the organisation follows a specific means of compliance to demonstrate compliance with the rule, that information may also be stated.

(d) As a second element, all the functional areas of the organisation in which Part - 145 functions are intended to be carried out (i.e. the types of maintenance - related activities), including subcontracting, need to be listed in order to identify the applicability of any topic to each functional area.

Powered by EASA eRules Page 449 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS (e) A matrix can be used, as shown in the example below, to capture the two elements mentioned above. This matrix is intended to be a living document to be customised by each particular organisation depending on its scope of work and its structure. This ma trix should represent the overall compliance of the audit system, and needs to be amended, as necessary, based upon any change to the applicable regulations, the procedures of the organisation or the functional areas of the organisation (e.g. a change in t he scope of work to include line maintenance, etc.)

Example (to be further completed) of an audit matrix for an organisation involved in aircraft base maintenance that does not hold airworthiness review privilege: Topic Requirement Exposition Functional areas Base Compliance Component … Subcontracting maintenance monitoring workshop Facilities 145.A.25(a)(1 … 1.8 X N/A X X ) AMC … 2.22 X N/A N/A X 145.A.25(a) … … … … … … … Personnel … … … … … … … 145.A.30(c) 1.4 N/A X N/A N/A … 145.A.30(d) 1.7, 2.22 X X X X … … … … … … … … 145.A.37 N/A N/A N/A N/A N/A … … … … … … … … … Record - 145.A.55 … … … … … … keeping … … … … … … … … … … … … … … … (f) The audit plan can be presented as a simplified schedule (see below), showing the operational areas of the organisation (i.e. where the maintenance - related activities are effectively carried out) against a timetable to indicate when each particular area wa s scheduled for audit and when the audit was completed. The audit plan should include a number of product audits (depending on the number of product lines), some of which should be unannounced (see AMC2 145.A.200(a)(6) ).

For each topic, the audit should check that the particular Part - 145 requirement is documented in the corresponding procedure in the expositio n, and that the procedure is effectively implemented in the operational area that is being audited. In addition, the audit should also identify any practice/process implemented in the operational area which has not been documented in any procedure in the e xposition.

Oversight principles

ED Decision 2022/011/R THE USE OF INFORMATION AND COMMUNICATION TECHNOLOGIES (ICT) FOR PERFORMING REMOTE AUDITS This GM provides technical guidance on the use of remote information and communication technologies (ICT) to support: − competent authorities when overseeing regulated organisations; − regulated organisations when conducting internal audits/monitoring compliance of their organisation with the relevant requirements, and when evaluating vendors, suppliers and subcontractors.

In the context of this GM: − ‘remote audit’ means an audit that is performed with the use of any real - time video and audio communication tools instead of the physical presence of the auditor on - site; the specificities of each type of approval need to be considered in addition to the g eneral overview (described below) when applying the ‘remote audit’ concept; − ‘auditing entity’ means the competent authority or organisation that performs the remote audit; − ‘auditee’ means the entity being audited/inspected (or the entity audited/inspected by the auditing entity via a remote audit); It is the responsibility of the auditing entity to assess whether the use of remote ICT constitutes a suitable alternative to the physical presence of an auditor on - site in accordance with the applicable requirements.

THE CONDUCT OF A REMOTE AUDIT The auditing entity that decides to conduct a remote audit should describe the remote audit process in its documented procedures and should consider at least the following elements: − The methodology for the use of remote ICT is sufficiently flexible and non - prescriptive in nature to optimise the conventional audit process.

− Adequate controls are defined and are in place to avoid abuses that could compromise the integrity of the audit process.

− Measures to ensure that the security and confidentiality are maintained throughout the audit activities (data protection and intellectual property of the organisation also need to be safeguarded).

Examples of the use of remote ICT during audits may include but are not limited to: − meetings by means of teleconference facilities, including audio, video and data sharing; Powered by EASA eRules Page 451 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS − assessment of documents and records by means of remote access, in real time; − recording, in real time during the process, of evidence to document the results of the audit, including non - conformities, by means of exchange of emails or documents, instant pictures, video or/and audio recordings; − visual (livestream video) and audio access to facilities, stores, equipment, tools, processes, operations, etc.

An agreement between the auditing entity and the auditee should be established when planning a remote audit, which should include the following: − determining the platform for hosting the audit; − granting security and/or profile access to the auditor(s); − testing platform compatibility between the auditing entity and the auditee prior to the audit; − considering the use of webcams, cameras, drones, etc. when the physical evaluation of an event (product, part, process, etc.) is desired or is necessary; − establishing an audit plan which will identify how remote ICT will be used and the extent of their use for the audit purposes to optimise their effectiveness and efficiency while maintaining the integrity of the audit process; − if necessary, time zone acknowledgement and management to coordinate reasonable and mutually agreeable convening times; − a documented statement of the auditee that they shall ensure full cooperation and provision of the actual and valid data as requested, including ensuring any supplier or subcontractor cooperation, if needed; and − data protection aspects.

The following equipment and set - up elements should be considered: − the suitability of video resolution, fidelity, and field of view for the verification being conducted; − the need for multiple cameras, imaging systems, or microphones, and whether the person that performs the verification can switch between them, or direct them to be switched and has the possibility to stop the process, ask a question, move the equipment, et c.; − the controllability of viewing direction, zoom, and lighting; − the appropriateness of audio fidelity for the evaluation being conducted; and − real - time and uninterrupted communication between the person(s) participating to the remote audit from both locations (on - site and remotely).

When using remote ICT, the auditing entity and the other persons involved (e.g. drone pilots, technical experts) should have the competence and ability to understand and utilise the remote ICT tools employed to achieve the desired results of the audit(s)/a ssessment(s). The auditing entity should also be aware of the risks and opportunities of the remote ICT used and the impacts they may have on the validity and objectivity of the information gathered.

Audit reports and related records should indicate the extent to which remote ICT have been used in conducting remote audits and the effectiveness of remote ICT in achieving the audit objectives, including any item that has not been able to be completely re viewed.

145.A.202 Internal safety reporting scheme

Regulation (EU) 2021/1963 (a) As part of its management system, the organisation shall establish an internal safety reporting scheme to enable the collection and evaluation of such occurrences that are to be reported under point 145.A.60 .

(b) The scheme shall also enable the collection and evaluation of those errors, near misses and hazards reported internally that do not fall under point (a).

(c) Through that scheme, the organisation shall: (1) identify the causes of, and contributing factors to, the errors, near misses and hazards reported, and address them as part of its safety risk management process in accordance with point 145.A.200(a)(3) ; (2) ensure an evaluation of all known, relevant information relating to errors, near misses, hazards and the inability to follow procedures, and a method to circulate the information as necessary.

(d) The organisation shall make arrangements to ensure the collection of safety issues related to subcontracted activities.

AMC1 145.A.202 Internal safety reporting scheme

ED Decision 2022/011/R (a) Each internal safety reporting scheme should ensure confidentiality and enable and encourage free and frank reporting of any potentially safety - related occurrence, including incidents such as errors or near misses, safety issues and identified hazards. Thi s will be facilitated by the establishment of a just culture.

(b) The internal safety reporting scheme should contain the following elements: (1) clearly identified aims and objectives with demonstrable corporate commitment; (2) a just culture policy as part of the safety policy, and related just culture implementation procedures; (3) a process to: (i) identify those reports which require investigation; and (ii) when so identified, investigate all the causal and contributing factors, including technical, organisational, managerial, or human factors issues, and any other contributing factors related to the occurrence, incident, error or near miss that was identifie d; Powered by EASA eRules Page 453 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL AND ORGANISATION REQUIREMENTS (iii) if adapted to the size and complexity of the organisation, analyse the collective data showing the trends and frequencies of the contributing factors; (4) appropriate corrective actions based on the findings of investigations; (5) initial and recurrent training for staff involved in internal investigations; (6) where relevant, the organisation should cooperate with the owner, operator or CAMO on occurrence investigations by exchanging relevant information to improve aviation safety.

(c) The internal safety reporting scheme should: (1) ensure the confidentiality of the reporter; (2) be closed loop, to ensure that actions are taken internally to address safety issues and hazards; and (3) feed into the recurrent training as defined in AMC3 145.A.30(e) whilst maintaining the appropriate confidentiality.

(d) Feedback should be given to staff both on an individual and a more general basis to ensure their continued support of the safety reporting scheme.

GM1 145.A.202 Internal safety reporting scheme

ED Decision 2022/011/R GENERAL (a) The overall purpose of the internal safety reporting scheme is to collect information reported by the organisation personnel and use this reported information to improve the level of compliance and safety performance of the organisation. The purpose is not to attribute blame.

(b) The objectives of the scheme are to: (1) enable an assessment to be made of the safety implications of each relevant incident (errors, near miss), safety issue and hazard reported, including previous similar issues, so that any necessary action can be initiated; and (2) ensure that knowledge of relevant incidents, safety issues and hazards is shared so that other persons and organisations may learn from them.

(c) The scheme is an essential part of the overall monitoring function and should be complementary to the normal day - to - day procedures and ‘control’ systems; it is not intended to duplicate or supersede any of them. The scheme is a tool to identify those i nstances in which routine procedures have failed or may fail.

(d) All reports should be retained, as the significance of such reports may only become obvious at a later date.

(e) The collection and analysis of timely, appropriate and accurate data will allow the organisation to react to the information that it receives, and to take the necessary action.

145.A.205 Contracting and subcontracting

Regulation (EU) 2021/1963 (a) The organisation shall ensure that when contracting or subcontracting any part of its maintenance activities: (1) the maintenance conforms to the applicable requirements; (2) any aviation safety hazard associated with such contracting or subcontracting is considered as part of the organisation’s management system.

(b) If the organisation subcontracts any part of its maintenance activities to another organisation, the subcontracted organisation shall work under the scope of approval of the subcontracting organisation.

GM1 145.A.205 Contracting and subcontracting

ED Decision 2022/011/R RESPONSIBILITY WHEN CONTRACTING OR SUBCONTRACTING MAINTENANCE (a) Regardless of the approval status of the subcontracted organisations, a Part - 145 organisation is responsible for ensuring that all subcontracted activities are subject to hazard identification and risk management, as required by point 145.A.200(a)(3) , and to compliance monitoring, as required by point 145.A.200(a)(6) .

(b) A Part - 145 organisation is responsible for identifying hazards that may stem from the existence of complex maintenance arrangements (such as when multiple organisations are contracted, or when multiple levels of contracting/subcontracting are included) with due regard to the organisations’ interfaces (see GM1 145.A.200(a)(3) ). In addition, the compliance monitoring function should at least check that the approval of the contracted maintenance organisation(s) effectively covers the contracted activities, and that it is still valid.

(c) A Part - 145 organisation is responsible for ensuring that interfaces and communication channels are established with the contracted maintenance organisation(s) for occurrence reporting. This does not replace the obligation of the contracted organisation (s) to report to the competent authority in accordance with Regulation (EU) No 1321/2014.

For subcontracted activities, interfaces and communication channels are also needed for the purpose of the internal safety reporting scheme ( 145.A.202 ).

GM2 145.A.205 Contracting and subcontracting

ED Decision 2022/011/R DIFFERENCE BETWEEN ‘CONTRACTING MAINTENANCE’ AND ‘SUBCONTRACTING MAINTENANCE’ (a) ‘Subcontracting maintenance’ means subcontracting to a third party under the maintenance organisation management system.

This is the case when a third party carries out certain maintenance tasks on behalf of the Part - 145 organisation, and the responsibility remains with the Part - 145 organisation (this Part - 145 organisation must have the tasks within its scope of approval). Whether the third party is approved or not is not relevant for the designation of subcontracting, si nce the third party will be working under the management system of the Part - 145 organisation, and the maintenance will be released under the approval of this organisation.

This is the case when a Part - 145 organisation, contracted to carry out maintenance by an owner/operator/CAMO, further contracts certain maintenance tasks to another approved Part - 145 organisation, and transfers the responsibility for the release of such ta sks to the second Part - 145 organisation.

Contracting should only be envisaged when it is allowed by the person or organisation that requests the maintenance.

(c) In case (a), the subcontracted organisation works under the approval of the contracting organisation, whereas in case (b), the contracted organisation works under its own approval.

GM1 145.B.200(a)(5) Management system

ED Decision 2022/011/R SAFETY RISK MANAGEMENT PROCESS The purpose of safety risk management as part of the management system framework for competent authorities is to ensure the effectiveness of the management system. As for any organisation, hazard identification and risk management are expected to contribut e to effective decision - making, to guide the allocation of resources and contribute to organisational success.

The safety risk management process required by point 145.B.200 is intended to address the safety risks that are directly related to the competent authority’s organisation and processes, and which may affect its capability to perform its tasks and discharge its responsibilities. This process is not intended to be a su bstitute for the State safety risk management SARPs defined in ICAO Annex 19, Chapter 3, component 3.3. This does not mean, however, that the competent authority may not use information and data that is obtained through its State Safety Programme (SSP), in cluding oversight data and information, for the purposes of safety risk management as part of its management system.

The safety risk management process is also to be applied to the management of changes ( 145.B.210 ), which is intended to ensure that the management system remains effective whenever changes occur.

AMC1 145.B.310 Initial certification procedure

ED Decision 2022/011/R VERIFICATION OF COMPLIANCE (a) In order to verify the organisation’s compliance with the applicable requirements, the competent authority should conduct an audit of the organisation, including interviews of the personnel, and inspections carried out at the organisation’s facilities.

(b) The competent authority should only conduct such an audit if it is satisfied that the application and the supporting documentation, including the results of the pre - audit performed by the organisation, are in compliance with the applicable requirements .

(c) The audit should focus on the following areas: (1) the detailed management structure, including the names and qualifications of personnel as required by points (a) , (b) , (c) and (ca) of point 145.A.30, and the adequacy of the organisation and its management structure; (2) the personnel: (i) the adequacy of the number of staff, and of their qualifications and experience with regard to the intended terms of approval and the associated privileges; (ii) the validity of any licences and/or authorisations, as applicable; (3) the processes used for safety risk management and compliance monitoring; (4) the facilities and their adequacy regarding the organisation’s scope of work; (5) the documentation based on which the certificate should be granted (i.e. the documentation required by Part - 145 ): (i) verification that the procedures specified in the MOE comply with the applicable requirements; and (ii) verification that the accountable manager has signed the exposition statement.

(d) If an application for an organisation certificate is refused, the applicant should be informed of the right of appeal that exists under national law.

AMC1 145.B.310(a) Initial certification procedure

ED Decision 2022/011/R AUDIT (a) The competent authority should determine how and by whom the audit shall be conducted. For example, it will be necessary to determine whether one large team audit, a short series of small team audits, or a long series of single inspector audits is most app ropriate for the particular situation.

(b) The audit may be structured so as to verify the organisation’s processes related to a product line. For example, in the case of an organisation with Airbus A310 and A320 ratings, the audit should concentrate on the maintenance processes of one aircraft type only for a full compliance Powered by EASA eRules Page 481 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION B — AUTHORITY REQUIREMENTS check, and depending upon the result, the second aircraft type may only require a sample check against those aspects that were seen to be weak regarding compliance for the first type.

(c) In determining the scope of the audit and which activities of the organisation will be assessed during the audit, the privileges of the approved organisation should be taken into account, e.g.

their approval to carry out airworthiness reviews.

(d) Competent authority auditing inspectors should always ensure that they are accompanied throughout the audit by a senior member of the organisation, who is normally the compliance monitoring manager. The reason for being accompanied is to ensure that th e organisation is fully aware of any findings raised during the audit.

(e) At the end of the audit, the auditing inspector should inform the senior member of the organisation of all the findings that were raised during the audit.

AMC1 145.B.310(c) Initial certification procedure

ED Decision 2022/011/R There may be occasions when the competent authority inspector is unsure about the compliance of some aspects of the organisation applying for the initial issue of a certificate. If this occurs, the inspector should inform the organisation about the possible non - compliance at the time, and about the fact that the situation will be reviewed within the competent authority before a decision is made.

If the review concludes that there is no finding, then a verbal confirmation to the organisation should suffice.

AMC2 145.B.310(c) Initial certification procedure

ED Decision 2022/011/R (a) The audit should be recorded using the audit report EASA Form 6 ( Appendix II to AMC2 145.B.310(c) ).

Level 1 findings shall also include: (1) any failure to grant the competent authority access to the organisation’s facilities referred to in point 145.A.140 during normal operating hours and after two written requests; Powered by EASA eRules Page 484 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) SECTION B — AUTHORITY REQUIREMENTS (2) obtaining the organisation certificate or maintaining its validity by falsification of the submitted documentary evidence; (3) any evidence of malpractice or fraudulent use of the organisation certificate; (4) the lack of an accountable manager.

(c) A level 2 finding shall be issued by the competent authority when any non - compliance is detected with the applicable requirements of Regulation (EU) 2018/1139 and its delegated and implementing acts, with the organisation’s procedures and manuals, or with the organisation’s certificate including the terms of approval, which is not classified as a level 1 finding.

(d) When a finding is detected during oversight or by any other means, the competent authority shall, without prejudice to any additional action required by Regulation (EU) 2018/1139 and its delegated and implementing acts, communicate in writing the finding t o the organisation and request corrective action to address the non - compliance identified. If a level 1 finding directly relates to an aircraft, the competent authority shall inform the competent authority of the Member State in which the aircraft is r egistered.

(1) If there are any level 1 findings, the competent authority shall take immediate and appropriate action to prohibit or limit the activities of the organisation involved and, if appropriate, it shall take action to revoke the certificate or to limit or suspe nd it in whole or in part, depending on the extent of the level 1 finding, until successful corrective action has been taken by the organisation.

(2) If there are any level 2 findings, the competent authority shall: (i) grant the organisation a corrective action implementation period that is appropriate to the nature of the finding, and that in any case shall initially not be more than 3 months. The period shall commence from the date of the written communication of the f inding to the organisation requesting corrective action to address the non - compliance identified. At the end of that period, and subject to the nature of the finding, the competent authority may extend the 3 - month period provided that a corrective acti on plan has been agreed with the competent authority; (ii) assess the corrective action plan and implementation plan proposed by the organisation, and if the assessment concludes that they are sufficient to address the non - compliance, accept them.

(3) If the organisation fails to submit an acceptable corrective action plan, or fails to perform the corrective action within the time period accepted or extended by the competent authority, the finding shall be raised to level 1 and action shall be taken as laid down in point (d)(1).

(4) The competent authority shall record all the findings that it has raised or that have been communicated to it in accordance with point (e) and, where applicable, the enforcement measures it has applied, as well as all corrective actions and the dates of th e action closures for all the findings.

(e) Without prejudice to any additional enforcement measures, when an authority performing the oversight tasks pursuant to point 145.B.300(d) identifies any non - compliance with the applicable requirements of Regulation (EU) 2018/1139 and its delegated and implementing acts by an organisation certified by the competent authority of another Member State or the Agency, it shall inform that compete nt authority and provide an indication of the level of the finding.

The observations issued under this point shall be communicated in writing to the organisation and recorded by the competent authority.

GM1 145.B.350(f) Findings and corrective actions; observations

ED Decision 2022/011/R DIFFERENCE BETWEEN ‘LEVEL 2 FINDING’ AND ‘OBSERVATION’ (a) ‘Findings’ are issued for non - compliance with the Regulation, whereas ‘observations’ may be issued to an organisation remaining compliant with the Regulation while additional inputs for the organisation could be considered for continuous improvement.

However, the competent authority may decide to issue a ‘level 2’ finding when the ‘observations’ process is not managed correctly or overlooked.

(b) Examples to help differentiate between a ‘level 2 finding’ and an ‘observation’ are provided below, based on the provisions for the control and calibration of tools in accordance with point 145.A.40(b) .

Example of a ‘level 2 finding’ − The organisation could not demonstrate compliance with some elements of 145.A.40(b) regarding the control register of the tools, equipment and particularly test equipment process as evidenced by: (1) the fact that some sampled tools physically available in the tools store were missing in the tools control register managed by the organisation; (2) the fact that one tool has not been correctly identified (e.g. incorrect P/N, S/N) in the tools control register.

Examples of ‘observations’ − Accumulation of tools in the store not sent yet for calibration. This situation could generate some consequences on the availability of tools and operational capabilities during a peak of activities (ineffectiveness of the process).

− The process to manage the tools control register through the dedicated software is not detailed enough (potential to cause a level 2 finding).

− The colour of the ‘unserviceable’ tag of the tools could generate some confusion. The organisation should consider changing the colour of this unserviceable tag to better alert the staff on the particular status of the unserviceable tools (potential improv ement).

Regulation (EU) No 1321/2014 The provisions of Appendix II to Annex I (Part - M) apply.

Powered by EASA eRules Page 488 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) APPENDICES TO ANNEX II (Part - 145)

Appendix II — Class and rating system for the terms of approval of

Part - 145 maintenance organisations

Regulation (EU) 2021/1963 (a) Except as stated otherwise for the smallest organisations referred to in point (m), the table referred to in point (l) provides the possible classes and ratings to be used to establish the terms of approval of the certificate of the organisation approved i n accordance with Annex II (Part - 145) . An organisation must be granted terms of approval that range from a single class and rating with limitations to all classes and ratings with limitations.

(b) In addition to the table in point (l), each maintenance organisation is required to indicate its scope of work in its MOE.

(c) Within the approval class(es) and rating(s) established by the competent authority, the scope of work specified in the MOE defines the exact limits of its approval. It is therefore essential that the approval class(es) and rating(s) and the organisation’s scope of work match.

(d) A category A class rating means that the maintenance organisation may carry out maintenance on aircraft and components (including engines and/or auxiliary power units (APUs)), in accordance with the aircraft maintenance data or, if agreed by the competent authority, in accordance with the component maintenance data, only while such components are fitted to the aircraft. Nevertheless, such an A - rated maintenance organisation may temporarily remove a component for maintenance in order to improve access to that component, except when its removal generates the need for additional maintenance that the organisation is not approved to perform. Such removal of component for maintenance by A - rated maintenance organisation shall be subject to an appropriate contro l procedure in the MOE.

The limitation column must specify the scope of such maintenance, thereby indicating the extent of the approval.

(e) Category A class ratings are subdivided into “Base” or “Line” maintenance categories. Such an organisation may be approved for either “Base” or “Line” maintenance, or both. It should be noted that a “Line” facility located at a main base facility requires a “Line” maintenance app roval.

(f) A category B class rating means that the maintenance organisation may carry out maintenance on uninstalled engines and/or APUs and engine and/or APU components, in accordance with the engine and/or APU maintenance data or, if agreed by the competent authority, in accordance with t he component maintenance data, only while such components are fitted to the engine and/or the APU. Nevertheless, such a B - rated approved maintenance organisation may temporarily remove a component for maintenance in order to improve access to that componen t, except when its removal generates the need for additional maintenance that the organisation is not approved to perform.

The limitation column must specify the scope of such maintenance, thereby indicating the extent of the approval.

A maintenance organisation that is approved with a category B class rating may also carry out maintenance on an installed engine during aircraft base and line maintenance, provided that an appropriate control procedure in the MOE has been approved by the c ompetent authority. The scope of work in the MOE shall reflect those activities if they are permitted by the competent authority.

Powered by EASA eRules Page 489 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex II (Part - 145) (Regulation (EU) No 1321/2014) APPENDICES TO ANNEX II (Part - 145) (g) A category C class rating means that the maintenance organisation may carry out maintenance on uninstalled components (excluding complete engines and APUs) that are intended to be fitted on the aircraft or the engine/APU.

The limitation column must specify the scope of such maintenance, thereby indicating the extent of the approval.

A maintenance organisation that is approved with a category C class rating may also carry out maintenance on an installed component (other than a complete engine/APU) during aircraft base and line maintenance, or at an engine/APU maintenance facility provi ded that an appropriate control procedure in the MOE has been approved by the competent authority. The scope of work in the MOE shall reflect those activities if they are permitted by the competent authority.

(h) A category D class rating is a self - contained class rating that is not necessarily related to a specific aircraft, engine or other component. The D1 – Non - Destructive Testing (NDT) rating is only necessary for a maintenance organisation that carries out NDT as a particular task fo r another organisation. A maintenance organisation that is approved with a class rating in the A, B or C category may carry out NDT on products that it maintains without the need for a D1 class rating provided that the MOE cont ains appropriate NDT procedures.

(i) The limitation column is intended to give competent authorities the flexibility to customise an approval for any particular organisation. Ratings may only be mentioned on the approval if they are appropriately limited. The table in point (l) specifies the types of limit ations that are possible. It is acceptable to stress in the limitation column the maintenance task rather than the type or manufacturer of the aircraft or engine, if that is more appropriate to the organisation (an example could be avioni cs systems installations and the related maintenance). If that is mentioned in the limitation column, it indicates that the maintenance organisation is approved to carry out maintenance up to and including that particular type/task.

(j) When reference is made to the series, type and group in the limitation column of class A and B, it shall be understood as follows: — “series” means a specific type series such as the Airbus 300, 310 or 319, or the Boeing 737 - 300 series, the RB211 - 524 series, the Cessna 150 or Cessna 172, the Beech 55 series, the continental O - 200 series, etc., — “type” means a specific type or model such as the Airbus 310 - 240 type, the RB 211 - 524 B4 type, or the Cessna 172RG type.

Any number of series or types may be quoted, — “group” means, for example, Cessna single piston engine aircraft or Lycoming non - supercharged piston engines, etc.

(k) By way of derogation from point 145.A.85(a)(1) , when a component capability list is used that could be subject to frequent amendments, then the organisation may propose to include such amendments in the procedure referred to in point 145.A.85(c) for changes not requiring prior approval.

GM 1 66.A.20(a) Privileges

ED Decision 2023/019/R 1. The following definitions apply: Electrical system means the aircraft electrical power supply source, plus the distribution system to the different components contained in the aircraft and relevant connectors. Lighting systems are also included in this definition. When working on cables and connectors whi ch are part of these electrical systems, the following typical practices are included in the privileges: − Continuity, insulation and bonding techniques and testing; − Crimping and testing of crimped joints; − Connector pin removal and insertion; − Wiring protection techniques.

Avionics system means an aircraft system that transfers, processes, displays or stores analogue or digital data using data lines, data buses, coaxial cables, wireless or other data transmission medium, and includes the system’s components and connectors. Examples of avio nics systems include the following: − Autoflight; − Communication, Radar and Navigation; − Instruments (see NOTE below); − In Flight Entertainment Systems; − Integrated Modular Avionics (IMA); − On - Board Maintenance Systems; − Information Systems; − Fly by Wire Systems (related to ATA27 ‘Flight Controls’); − Fibre Optic Control Systems.

NOTE: Instruments are formally included within the privileges of the B2 and B2L with system rating ‘instruments’ . However, maintenance on electromechanical and pitot - static components may also be released by a B1 , B3 or L licenc e holder.

Simple test means a test described in approved maintenance data and meeting all the following criteria: Powered by EASA eRules Page 519 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS − The serviceability of the system can be verified using aircraft controls, switches, Built - in Test Equipment (BITE), Central Maintenance Computer (CMC) or external test equipment not involving special training.

− The outcome of the test is a unique go – no go indication or parameter, which can be a single value or a value within an interval tolerance. No interpretation of the test result or interdependence of different values is allowed.

− The test does not involve more than 10 actions as described in the approved maintenance data (not including those required to configure the aircraft prior to the test, i.e. jacking, flaps down, etc, or to return the aircraft to its initial configuration). Pushing a control, switch or button, and reading the corresponding outcome may be considered as a single step even if the maintenance data shows them separated.

Troubleshooting means the procedures and actions necessary, using approved maintenance data, in order to identify the root cause of a defect or malfunction. It may include the use of BITE or external test equipment.

Line maintenance : refer to AMC1 145.A.10 Base m aintenance : refer to AMC1 145.A.10 2. The category B3 licence does not include any A subcategory. Nevertheless, this does not prevent the B3 licence holder from releasing maintenance tasks typical of the A1.2 subcategory for piston - engine non - pressurized aeroplanes of 2 000 kg MTOM and belo w, within the limitations contained in the B3 licence.

3. The B1.2 and B3 licences do not include any L subcategory. Nevertheless, the holder of a B1.2 or B3 licence with the appropriate ratings is entitled to receive, upon application, licences in the L1 and L2 subcategories under the conditions described in poi nt 66.B.110(d) .

4. The privileges of the B2 licence with given aircraft ratings include the privileges of the B2L licence for all the system ratings for the same aircraft ratings. Nevertheless, the holder of a B2 licence with given aircraft ratings may apply for a B2L lic ence in order to include a different aircraft rating if the applicant only wants to demonstrate compliance with the experience requirements for certain system ratings.

5. The category C licence permits certification of base maintenance by the issue of a single certificate of release to service for the complete aircraft after the completion of all such maintenance. The basis for this certification is that the maintenance has been carried out by competent mechanics , and category B1, B2 , B2L, B3 and L support staff, as appropriate, have signed for the maintenance tasks under their respective specialisation. The principal function of category C certifying staff is to ensure that all required maintenance has been called up and signed off by category B1, B 2 , B2L, B3 and L support staff, as appropriate, before issue of the certificate of release to service. Only category C personnel who also hold category B1, B2 , B2L, B3 or L qualifications may perform both roles in base maintenance.

AMC 66.A.20(a)(4) Privileges

ED Decision 2019/009/R ‘Within the limits of the system ratings specifically endorsed on the licence’ refers to the fact that the privileges of the licence holder are limited: − to the group/subgroup of aircraft endorsed on the licence, but also − to the system rating(s) endorsed.

Powered by EASA eRules Page 520 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS When an applicant wishes to get the privilege to issue certificates of release to service and to act as support staff for electrical and avionics tasks within powerplant and mechanical systems, he/she should apply for the rating ‘airframe system’ on the B2 L licence. The reason is that the ‘airframe systems’ rating is the only rating which covers completely the electrical and avionics tasks of the powerplant and mechanical systems of the aircraft.

AMC 66.A.20(b) ( 2 ) Privileges

ED Decision 2020/002/R The 6 months of maintenance experience in the preceding 2 - year period should be understood as consisting of two elements, duration and nature of the experience. The minimum to meet the requirements for these elements may vary depending on the size and complexity of the aircraft and type of operation and maintenance.

1. Duration: Within an approved maintenance organis ation: − 6 months of continuous employment within the same organisation; or − 6 months split up into different blocks, employed within the same or in different organisations.

The 6 - month period can be replaced by 100 days of maintenance experience in accordance with the privileges, whether they have been performed within an approved organisation or as independent certifying staff according to M.A.801(b)1 , or as a combination thereof.

When a licence holder maintains and releases aircraft in accordance with M.A.801(b)1 , in certain circumstances this number of days may even be reduced by 50% when agreed in advance by the competent authority. These circumstances consider the cases where the licence holder happens to be the owner of an aircraft and carries out maintenance on his /her own aircraft, or where a licence holder maintains an aircraft operated for low utilis ation, that does not allow the licence holder to accumulate the required experience. This reduction should not be combined with the 20% reduction permitted when carrying out technical support, or maintenance planning, continuing airworthiness management or engineering activities. To avoid a too long period without experience, the working days shoul d be spread over the intended 6 - month period.

2. Nature of the experience: Depending on the category of the aircraft maintenance licence, the following activities are considered relevant for maintenance experience: − Servicing; − Inspection; − Operational and functional testing; − Trouble - shooting; − Repairing; − Modifying; − Changing component; − Supervising these activities; Powered by EASA eRules Page 521 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS − Releasing aircraft to service.

For category A licence holders, the experience should include exercising the privileges, by means of performing tasks related to the authorization on at least one aircraft type for each licence subcategory. This means tasks as mentioned in AMC 145.A.30(g) , including servicing, component changes and simple defect rectifications.

For category B1, B2 , B2L, B3 and L , for every aircraft included in the authori s ation the experience should be on that particular aircraft or on a similar aircraft within the same licence (sub)category. Two aircraft can be considered to be similar when they have similar technology, construction and comparable systems, which means equally equipped with the following (as applicable to the licence category): − Propulsion systems (piston, turboprop, turbofan, turboshaft, jet - engine or push propellers); and − Flight control systems (only mechanical controls, hydro - mechanically powered controls or electro - mechanically powered controls); and − Avionic systems (analogue systems or digital systems); and − Structure (manufactured of metal, composite or wood).

For licences endorsed with (sub)group ratings: − In the case of a B1 licence endorsed with (sub)group ratings (either manufacturer sub - group or full (sub)group) as defined in 66.A.45 , the holder should show experience on at least one aircraft type per (sub)group and per aircraft structure (metal, composite, wood).

− In the case of a B2 or B2L licence endorsed with (sub)group ratings (either manufacturer subgroup or full (sub)group) as defined in 66.A.45 , the holder should show experience on at least one aircraft type per (sub)group.

− In the case of a B3 licence endorsed with the rat ing ‘piston - engine non - pressuris ed aeroplanes of 2000 kg MTOM and below’ as defined in 66.A.45 , the holder should show experience on at least one aircraft type per aircraft structure (metal, metal - tubing with fabric, composite, wooden).

For category C, the experience should cover at least one of the aircraft types endorsed on the licence.

For a combination of categories, the experience should include some activities of the nature shown in paragraph 2 in each category.

A maximum of 20% of the experience duration required may be replaced by the following relevant activities on an aircraft type of similar technology, construction and with comparable systems: − Aircraft maintenance related training as an instructor/assessor or as a student; − Maintenance technical support/engineering; − Maintenance management/planning.

The experience should be documented in an individual log book or in any other recording system (which may be an automated one) containing the following data: − Date; Powered by EASA eRules Page 522 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS − Aircraft type; − Aircraft identification i.e. registration; − ATA chapter (optional); − Operation performed e.g. 100 FH check, MLG wheel change, engine oil check and complement, SB embodiment, trouble shooting, structural repair, STC embodiment, etc.; − In the particular case of Part - 145 organisations, the type of maintenance i.e. base, line; − Type of activity i.e. perform, supervise, release; − Subcategory used (A1, A2, A3, A4, B1.1, B1.2, B1.3, B1.4, B2, B2L, B3, C or L1, L1C, L2, L2C, L3G, L3H, L4G, L4H, L5); − Duration in days or partial - days.

GM 66.A.20(b)2 Privileges

ED Decision 2015/029/R The sentence ‘met the provision for the issue of the appropriate privileges’ included in 66.A.20(b)2 means that during the previous 2 years the person has met all the requirements for the endorsement of the corresponding aircraft rating (for example, in the case of aircraft in Group 1, theoretical plus practical element plus, if applicable, on - the - job tr aining). This supersedes the need for 6 months of experience for the first 2 years. However, the requirement of 6 months of experience in the preceding 2 years will need to be met after the second year.

AMC 66.A.20(b)3 Privileges

ED Decision 2015/029/R The wording ‘has the adequate competence to certify maintenance on the corresponding aircraft’ means that the licence holder and, if applicable, the organisation where he/she is contracted/employed, should ensure that he/she has acquired the appropriate knowledge, skills, attitude and experience to release the aircraft being maintained. This is ess ential because some systems and technology present in the particular aircraft being maintained may not have been covered by the training/examination/experience required to obtain the licence and ratings.

This is typically the case, among others, in the following situations: − Type ratings which have been endorsed on a licence in accordance with Appendix I to AMC to Part - 66 ‘List of Type Ratings’ after attending type training/on - the - job training which did not cover all the models/variants included in such rating. For example, a licence endorsed with the rating Airbus A318/A319/A320/A321 (CFM56) after attending type training/ on - the - job training covering only the Airbus 320 (CFM56).

− Type ratings which have been endorsed on a licence in accordance with Appendix I to AMC to Part - 66 ‘List of Type Ratings’ after a new variant has been added to the rating in Appendix I, without performing difference training. For example, a licence endorsed with the rating Boeing 737 - 600/700/800/900 for a person who already had the rating Boeing 737 - 60 0/700/800, without performing any difference training for the 737 - 900.

− Work being carried out on a model/variant for which the technical design and maintenance techniques have significantly evolved from the original model used in the type training/on - the - job training.

Powered by EASA eRules Page 523 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS − Specific technology and options selected by each customer which may not have been covered by the type training/on - the - job training.

− Changes in the basic knowledge requirements of Appendix I to Part - 66 not requiring re - examination of existing licence holders (grandfathered privileges).

− The endorsement of group/subgroup ratings based on experience on a representative number of tasks/aircraft or based on type training/examination on a representative number of aircraft.

− Persons meeting the requirements of 6 months of experience every 2 years only on certain similar aircraft types as allowed by AMC 66.A.20(b)2 .

− Persons holding a Part - 66 licence with limitations, obtained through conversion of national qualifications ( 66.A.70 ), where such limitations are going to be lifted after performing the corresponding basic knowledge examinations. In this case, the type ratings endorsed in the licence may have been obtained in the national system without covering all the aircraft systems (because of the previous limitations) and there will be a need to assess and, if applicable, to train this person on the missing systems.

Additional information is provided in AMC 145.A.35(a) .

GM 66.A.20(b)4 Privileges

Maintenance experience on operating aircraft: − means the experience of being involved in maintenance tasks on aircraft which are being operated by airlines, air taxi organisations, aero clubs, owners, etc., as relevant to the licence category/subcategory ; − should cover a wide range of tasks in terms of length, complexity and variety; − aims at gaining sufficient experience in the real environment of maintenance as opposed to only the training school environment ; − may be gained within different types of maintenance organisations ( Part - 145 , M.A.

Subpart F , Part - CAO, FAR - 145, etc.) or under the supervision of independent certifying staff; − m ay be combined with Part - 147 approved training (or other training approved by the competent authority) so that periods of training can be intermixed with periods of experience, similar to an apprenticeship ; − may be full - time or part - time, either as a professional or on a voluntary basis; Powered by EASA eRules Page 528 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS − in the case of the L licence, it is acceptable that the 1 or 2 years of experience required by 66.A.30(a)(2b) covers maintenance performed only during the weekends (or equivalent periods) as long as the applicant has achieved a sufficient level of competency related to the applicable licence subcategory as attested by the corresponding statement(s) issued by the maintenance organisation(s) or independent certifying staff that supervised the applicant.

2 . A skilled worker is a person who has successfully completed a training, acceptable to the competent authority, involving the manufacture, repair, overhaul or inspection of mechanical, electrical or electronic equipment. The training would include the use of tools and measuring devices.

3 . In the case of an applicant for a licence , including several categories/subcategories, it is acceptable to combine the periods of experience as long as there is sufficient experience for each category/subcategory during the required period. Examples: − Application for a B1.1 (turbine aeroplanes) + B1.3 (turbine helicopters): t he Regulation requires 5 years of experience for B1.1 and 5 years of experience for B1.3 for an applicant with no relevant previous technical training .

− It is not acceptable to combine the experience in a single 5 - year period where the applicant has been working for 3 years on turbine aeroplanes and 2 years on turbine helicopters.

− However, it is acceptable to combine the experience in a single 5 - year period if the applicant has been working for 5 years on turbine aeroplanes and turbine helicopters (for example, aeroplanes in the morning, helicopters in the afternoon, or a few days e very week on aeroplanes and a few days every week on helicopters).

− Application for a B1.1 (turbine aeroplanes) + B2 (avionics): t he Regulation requires 5 years of experience for B1.1 and 5 years of experience for B2 for an applicant with no relevant previous technical training.

− It is not acceptable to combine the experience in a single 5 - year period where the applicant has been working for 3 years on turbine aeroplanes (with no avionics work) and 2 years on avionics systems.

− However, it is acceptable to combine the experience in a single 5 - year period if the applicant has been working for 5 years on structures, powerplant, mechanical and electrical systems and avionics (for B1.1 tasks in the morning, B2 tasks in the afternoon, or a few days every week for B1.1 tasks and a few days every week for B2 tasks).

− Application for a B1.1, B1.2, B1.3, B1.4 and B2: t he Regulation requires 5 years of experience for B1.1, B1.3 and B2 , and 3 years of experience for B1.2 and B1.4 for an applicant with no relevant previous technical training.

− In this case, it is very unlikely that the experience for each category/subcategory would be sufficient.

4. For a category C applicant that holds an academic degree, the participation in the performance of maintenance tasks on operating aircraft may include maintenance, maintenance planning, quality assurance, record - keeping, spare parts management and engine ering development.

‘Experience in working in a civil aircraft maintenance environment on a representative selection of tasks directly associated with aircraft maintenance’ means experience gained at an Powered by EASA eRules Page 529 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS organisation that is approved in accordance with Part - 145 , Part - CAO , Part - CAMO or similar, or experience in performing comparable work that is directly related to the continuing airworthiness of aircraft within a competent authority. Similar work performed on ‘Annex I aircraft’ or state aircraft may be acceptable as well.

‘Including 6 months of participation in the performance of base maintenance tasks’ on operating aircraft means experience gained through the active participation in base maintenance checks at maintenance organisations.

If the applicant has acquired experience on operating CMPA, the corresponding category C licence should be issued. If the experience acquired has been limited to other than CMPA, then only the corresponding category C licence with respect to other than CMP A should be issued.

While it is strongly recommended that the participation in the performance of maintenance on aircraft should be at the level required for the issue of a B1 or B2 licence, the objective of the required experience is to gain insight into the performance of b ase maintenance. The applicant for an academic category C licence should be aware of the type of maintenance carried out before the signature of support staff and understand their roles in the release - to - service process of base maintenance. It is encourage d that the future category C licence holder participates in both simple and complex tasks during their experience in base maintenance and gains insight in some aircraft critical systems.

In the case presented in point 66.A.30(e) , for the required experience gained outside the European civil regulatory framework, at least 1 year should be in a Part - 145 or Part - CAO environment, including participation in the performance of base maintenance tasks for 6 months.

GM 66.A.45(b) Endorsement with aircraft ratings

ED Decision 2020/002/R An aircraft type rating includes all the aircraft models/variants listed in column 2 of Appendix I to AMC to Part - 66 .

When a person already holds a type rating on the licence and such type rating is amended in the Appendix I to AMC to Part - 66 in order to include additional models/variants, there is no need for additional type training for the purpose of amending the type rating in the licence. The rating should be amended to include the new variants, upon request by the applicant, without addi tional requirements. However, it is the responsibility of the licence holder and, if applicable, the maintenance organisation where he/she is employed to comply with 66.A.20(b)3 , 145.A.35(a) , M.A.607(a) , and CAO.A.040 as applicable, before he/she exercises certification privileges.

Similarly, type training courses covering certain, but not all the models/variants included in a type rating, are valid for the purpose of endorsing the full type rating.

AMC 66.A.45(d);(e)3;(f)1;(g)1;(h) Endorsement with aircraft ratings

ED Decision 2019/009/R 1. The ‘practical experience’ should cover a representative cross section including at least: − for categories B1, B2, B2L and B3: 50 % of the tasks contained in Appendix II to the AMC relevant to the licence category and to the applicable aircraft type ratings or aircraft (su b)group ratings being endorsed; − for category L: − in the subcategories L1, L1C, L2 or L2C: 50 % as in the paragraph related to B1, B2, B2L or B3; − in the subcategories L3H and L3G for ‘Balloons’ or L4H, L4G and L5 for ‘Airships’, 80 % of the tasks should be demonstrated, and should include the tasks identified with an asterisk (*) in the Appendix; This experience should cover tasks from each paragraph of the Appendix II list. Other tasks than those in the Appendix II may be considered as a replacement when they are relevant. In the case of (sub)group ratings, this experience may be shown by covering one or several aircraft types of the applicable (sub)group and may include experience on aircraft classified in group 1, 2 and/or 3 as long as the experience is relevant. The practical experience should be obtained under the supervision of authorised cert ifying staff.

2. In the case of endorsement of individual type ratings for Group 2 and Group 3 aircraft, for the second aircraft type of each manufacturer (sub)group the practical experience should be reduced to 30% of the tasks contained in Appendix II to AMC relevant to the licence category and to the applicable aircraft type. For subsequent aircraft types of each manufacturer (sub) group this should be reduced to 20%.

3. Practical experience should be demonstrated by the submission of records or a log book showing the Appendix II tasks performed by the applicant. Typical data to be recorded are similar to those described in AMC 66.A.20(b)2 .

AMC 66.A.45(e) Endorsement with aircraft ratings

ED Decision 2015/029/R 1. For the granting of manufacturer subgroup ratings for Group 2 aircraft, for B1 and C licence holders, the sentence ‘at least two aircraft types from the same manufacturer which combined are representative of the applicable manufacturer subgroup’ means t hat the selected aircraft types should cover the technologies relevant to the manufacturer subgroup in the following areas: − Flight control systems (mechanical controls/hydromechanically powered controls / electromechanically powered controls); and − Avionic systems (analogue systems / digital systems); and − Structure (manufactured of metal / composite / wood).

In cases where there are very different aircraft types within the same manufacturer subgroup, it may be necessary to cover more than two aircraft types to ensure adequate representation.

For this purpose it may be possible to use aircraft types from the same manufacturer classified in Group 1 as long as the selected aircraft belong to the same licence subcategory for which the rating will be endorsed.

2. For the granting of full subgroup ratings for Group 2 aircraft, for B1 and C licence holders, the sentence ‘at least three aircraft types from different manufacturers which combined are representative of the applicable subgroup’ means that the selected aircraft types should cover all the technologies relevant to the manufacturer subgroup in the following areas: − Flight control systems (mechanical controls/hydromechanically powered controls / electromechanically powered controls); and − Avionic systems (analogue systems / digital systems); and − Structure (manufactured of metal / composite / wood).

In cases where there are very different aircraft types within the same subgroup, it may be necessary to cover more than three aircraft types to ensure adequate representation.

For this purpose it may be possible to use aircraft types from different manufacturers classified in Group 1 as long as the selected aircraft belong to the same licence subcategory for which the rating will be endorsed.

3. For manufacturer subgroup ratings, the term ‘manufacturer’ means the TC holder defined in the certification data sheet, which is reflected in the list of type ratings in Appendix I to AMC to Part - 66 .

In the case of an aircraft rating where the type rating refers to a TC holder made of a combination of two manufacturers which produce a similar aircraft (i.e. AGUSTA / BELL HELICOPTER TEXTRON or any case of aircraft similarly built by another manufacturer ) this combination should be considered as one manufacturer.

As a consequence: − When a licence holder gets a manufacturer type or a manufacturer subgroup rating made of a combination of manufacturers, it covers the combination of such manufacturers.

− When a licence holder who intends to endorse a full subgroup rating selects three aircraft from different manufacturers, this means from different combinations of manufacturers as applicable.

ED Decision 2020/002/R 1. The appropriate experience required to remove the limitations referred to in 66.A.45(f) , (g) and (h) should consist of the performance of a variety of tasks appropriate to the limitations under the supervision of authorised certifying staff. This should include the tasks required by a scheduled annual inspection. Alternatively, this experience may also b e gained, if agreed by the competent authority, by theoretical and practical training provided by the manufacturer, as long as an assessment is further carried out and recorded by this manufacturer.

2. It is acceptable to have this experience i n just one aircraft type, provided this type is representative of the (sub)group in relation to the limitation being removed.

3. It is acceptable that this experience is gained in aircraft not covered by the Basic Regulation, provided that this experience is relevant and representative of the corresponding (sub)group.

An example c ould be the experience required to remove a limitation such as ‘aircraft with metal tubing structure covered with fabric’, which may be gained in ultralight aircraft (Annex I aircraft).

4 . The application for the limitation removal should be supported by a record of experience signed by the authorised certifying staff or by an assessment signed by the manufacturer after completion of the applicable theoretical and practical training.

66.A.55 Evidence of qualification

Regulation (EU) No 1321/2014 Personnel exercising certification privileges as well as support staff shall produce their licence, as evidence of qualification, within 24 hours upon request by an authorised person.

66.A.70 Conversion provisions

Regulation (EU) 2018/1142 (a) The holder of a certifying staff qualification valid in a Member State, prior to the date of entry into force of Annex III (Part - 66) shall be issued an aircraft maintenance licence by the competent authority of this Member State without further examination subject to the conditions specified in Section B Subpart D .

(b) A person undergoing a certifying staff qualification process valid in a Member State, prior to the date of entry into force of Annex III (Part - 66) may continue to be qualified. The holder of a certifying staff qualification gained following such process shall be issued an aircraft maintenance licence by the competent authority of this Member State without further examination subject to the condition s specified in Section B Subpart D .

(c) Where necessary, the aircraft maintenance licence shall contain limitations in accordance with point 66.A.50 to reflect the differences between: (i) the scope of the certifying staff qualification valid in the Member State before the entry into force of the applicable licence category or subcategory provided for in this Annex (Part - 66); (ii) the basic knowledge requirements and the basic examination standards laid down in Appendices I and II to this Annex (Part - 66) .

(d) By derogation from point (c), for aircraft not used by licenced air carriers in accordance with Regulation (EC) No 1008/2008, other than complex motor - powered aircraft, and for balloons, sailplanes, motor - powered sailplanes and airships, the aircraft main tenance licence shall contain limitations in accordance with point 66.A.50 to ensure that the certifying staff privileges valid in the Member State before the entry into force of the applicable Part - 66 licence category/subcategory and those of the converted Part - 66 aircraft maintenance licence remain the same.

GM 66.A.70 Conversion provisions

ED Decision 2019/009/R 1. As described in point 66.A.70 , the conversion provisions apply to the holder of a certifying staff qualification valid in a Member State prior to the date of entry into force of Annex III (Part - 66) .

The sentence ‘the holder of a certifying staff qualification valid in a Member State’ means any person who had a qualification valid in that Member State allowing that person the performance of activities identical to the privileges of ‘certifying staff’ contained in Regulation (EU) 1321/2014. This means that the signature of that person was sufficient to declare that the maintenance had been properly performed and the aircraft was ready for service and fit for flight in respect to such maintenance.

This should not been mistaken with the responsibilities linked to the airworthiness review, which was performed at different periods (typically varying from 6 months to 3 years) in the national systems. This is an activity which is performed at very specif ic points of time and not after every maintenance activity. Since an airworthiness review (or equivalent term used in the Powered by EASA eRules Page 541 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS national systems) is not performed after every maintenance event before the aircraft takes flight, an airworthiness review cannot be considered as a maintenance release. This means that the conversion provisions described in 66.A.70 are not applicable to persons performing airworthiness review functions unless their signature was required after every maintenance event before the aircraft can take flight.

2. The conversion applies to ‘certifying staff qualifications’ such as, for example: − holding a national licence (or completed the process to obtain such a national licence); − having completed a qualification process defined by the competent authority , or equivalent body under the national system , to become certifying staff; − having completed the qualification requirements for certifying staff within a maintenance organisation, as defined in their procedures.

This does not mean that in order to be entitled to a conversion process, the applicant has to be exercising certification privileges. A person may hold a ‘certifying staff qualification’ while not having certification privileges (or while exercising very l imited certification privileges below his/her qualification) for different reasons such as, for example, the following: − The person is working as ‘support staff’ in the base maintenance environment; − The person has been authorised only for a very limited range of tasks (lower than what he/she would be entitled if his/her qualification is considered) since the person is working in a line station where the scope of tasks is very limited; − The person holds a licence with a wider scope than the scope of the organisation where he/she is employed; − The person is working outside the aviation industry or is temporarily on leave due to different reasons (medical, personal, etc).

These persons are entitled to have the conversion performed in accordance with the full scope of their qualification and the full privileges that they would be entitled to hold on the basis of such qualification.

3. As described in point 66.A.70 , certifying staff qualifications eligible for conversion are those valid ‘prior to the date of entry into force of Annex III (Part - 66) ’, which means those qualifications valid before the following dates: − 28 September 2005 for aircraft above 5 700 kg MTOM; − 28 September 2006 for aircraft of 5 700 kg MTOM and below.

Nevertheless, since the B3 , B2L and L licences did not exist at those dates, certifying staff qualifications eligible for conversion to a B3 , B2L and L licence are those valid before the competent authority had the obligation to start issuing such licences, which means the following: − f or the B3 licence, those qualifications valid before 28 September 2012; − for the B2L licence, those qualifications valid before 5 March 2019; − for the L licence, those qualifications valid before 1 October 2019.

4. Although only those certifying staff qualifications gained prior to the dates indicated above are eligible for conversion, this does not mean that the application for conversion has to be Powered by EASA eRules Page 542 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS submitted prior to those dates. The applicant is entitled to have the conversion performed irrespective of when he/she applies for conversion.

5. A certifying staff qualification can be subject to more than one conversion process and can also be converted to more than one licence (sub)category (with any applicable limitations). This could be the case, for example, of a person who already had the certifying staff qualification converted in the past to a B1.2 licence with limitations linked to some missing elements of the Part - 66 Appendix I and II standard (following 66.A.70(c) ). This person would be entitled to apply and have his/her certifying staff qualification converted to a B1.2 or a B3 or L licence on the basis of 66.A.70(d) , which would mean no need to compare with the Part - 66 Appendix I , II or VII standard, introducing only those limitations required in order to maintain the existing privileges.

GM 66.A.70(c) Conversion provisions

ED Decision 2015/029/R For example, a limitation could be where a person holds a pre - existing certifying staff qualification which covered, to the standard of Part - 66 Appendix I and II, all the modules/subjects corresponding to the B1 licence except for electrical power systems. This person would be issued a Part - 66 aircraft maintenance licence in the B1 category with a limitation (exclusion) on electrical power systems.

For removal of limitations, refer to 66.A.50(c) .

GM 66.A.70(d) Conversion provisions

ED Decision 2023/013/R For aircraft not used by air carriers licensed in accordance with Regulation (EC) No 1008/2008 other than complex motor - powered aircraft, an example of limitations could be where a person holds a pre - Part - 66 qualification which covered privileges to release work performed on aircraft structures, powerplant, mechanical and electrical systems but excluded privileges on aircraft equipped with t urbine engine, aircraft above 2 000 kg MTOM, pressurised aircraft and aircraft equipped with retractable landing gear. This person would be issued with a Part - 66 aircraft maintenance licence in the B1.2 or B3 (sub)category with the following limitations (exclusions): − aircraft used by air carriers licensed in accordance with Regulation (E C ) No 1008/2008 (this limitation always exists); − aircraft above 2 000 kg MTOM; − pressurised aircraft; − aircraft equipped with retractable landing gear.

Another example of limitations could be where a pilot - owner holds a pre - Part - 66 qualification which covered privileges to release work performed on aircraft structures, powerplant, mechanical and electrical systems but limited to their own aircraft and limited to a particular aircraft type (for example, a Cessna 172). This pilot - owner would receive a Part - 66 aircraft maintenance licence in the B1.2 or B3 (sub)category with the following limitations (exclusions): − aircraft used by air carriers licensed in accordance with Regulation (EC) No 1008/2008 (this limitation always exists); − aircraft other than a Cessna 172; − aircraft not owned by the licence holder.

Powered by EASA eRules Page 543 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS One more example would be the case where a person holds a pre - Part - 66 qualification that covers privileges to release work on composite and metal sailplanes and powered sailplanes, covering aircraft structures, powerplant, mechanical and electrical systems . This person would be issued a Part - 66 aircraft maintenance licence in the L2 subcategory, with the following limitations (exclusions): − ELA1 aeroplanes; − wooden - structure aircraft covered with fabric; − aeroplanes with metal - tubing structure covered with fabric.

And one more example would be the case where a person holds a pre - Part - 66 qualification that covers privileges to release work on composite sailplanes up to the annual inspection but not including complex maintenance tasks, repairs and changes. This person would be issued a Part - 66 aircraft maintenance licence in the L1C subcategory, with the following limitations: − complex maintenance tasks described in Appendix VII to Annex I (Part - M) , standard changes described in point 21.A.90B of Part 21 or points 21L.A.62 or 21L.A.102 of Part 21 Light , and standard repairs described in point 21.A.431B of Part 21 or points 21L.A.202 or 21L.A.222 of Part 21 Light .

The essential aspect is that the limitations are established in order to maintain the privileges of the pre - Part - 66 qualification without comparing the previous qualification with the standard of Part - 66 Appendix I and II .

For removal of limitations, refer to 66.A.50(c) .

GM 66.B.200 Examination by the competent authority

ED Decision 2020/002/R 1. Questions may be prepared in the national language but the use of aviation English is recommended wherever possible.

2. The primary purpose of essay questions is to determine that the candidate can express themselves in a clear and concise manner and can prepare a concise technical report for the maintenance record, which is why only a few essay questions are required.

3. Oral type questions may not be used as the primary means of examination because of the difficulty in establishing consistency of standards between examiners or day - to - day.

However, nothing prevents the competent authority from meeting potential certifying staff for the purpose of ensuring they understand their obligations and responsibilities in the application of maintenance Parts.

4. For pass mark purposes, the essay questions should be considered as separate from the multiple choice questions.

5. Multiple choice question (MCQ) generation.

The following principles should be observed when developing multiple choice question: (a) The examination should measure clearly formulated goals. Therefore the field and depth of knowledge to be measured by each question should be fully identified.

(b) All the questions should be of the multiple choice type with three alternative answers.

(c) Questions that require specialised knowledge of specific aircraft types should not be asked in a basic licence examination.

(d) The use of abbreviations and acronyms should generally be avoided. However where needed, only internationally recognised abbreviations and acronyms should be used. In case of doubt use the full form, e.g. angle of attack = 12 degrees instead of a= 12°.

(e) Questions and answers should be formulated as simply as possible: the examination is not a test of language. Complex sentences, unusual grammar and double negatives should be avoided.

(f) A question should comprise one complete positive proposition. No more than 3 different statements should appear among the suggested responses otherwise the candidate may be able to deduce the correct answer by eliminating the unlikely combinations of s tatements.

(g) Questions should have only one true answer.

(h) The correct answer should be absolutely correct and complete or, without doubt, the most preferable. Responses that are so essentially similar that the choice is a matter of opinion rather than a matter of fact should be avoided. The main interest in M CQs is that they can be quickly performed: this is not achieved if doubt exists about the correct answer.

(i) The incorrect alternatives should seem equally plausible to anyone ignorant of the subject. All alternatives should be clearly related to the question and of similar vocabulary, grammatical structure and length. In numerical questions, the incorrect an swers should correspond to procedural errors such as corrections applied in the wrong sense or incorrect unit conversions: they should not be mere random numbers.

Powered by EASA eRules Page 559 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) SECTION B — PROCEDURES FOR COMPETENT AUTHORITIES (j) Calculators are not allowed during examination. Therefore all calculations should be feasible without a calculator. Where a question involves calculations not feasible without a calculator, such as , then the question should specify the approximate value of .

(k) Questions should be in accordance with Part - 66 examination syllabus ( Appendix I and Appendix VII ).

6. Essay question generation (a) The purpose of the essay is to allow the competent authority to determine if candidates can express themselves in a clear and concise manner in the form of a written response, in a technical report format using the technical language of the aviation in dustry. The essay examination also allows to assess, in part, the technical knowledge retained by the individual and with a practical application relevant to a maintenance scenario.

(b) Questions should be written so as to be broad enough to b e answered by candidates for any A or B licence category or subcategories and comply with the following general guidelines: − the question topic selected should be generic, applicable to mechanical as well as avionic licence categories and have a common technical difficulty level as indicated in Part - 66 Appendix I or Appendix VII ; − cover technology applicable to most areas of aircraft maintenance; − reflects common working practices; − it is not type - or manufacturer - specific and avoids subjects which are rarely found in practice; − when drafting a question , there is need to ensure consideration is given to the limited practical experience that most candidates will have.

(c) To make the questions and the marking procedures are as consistent as possible, each question and model answer, with the required key areas required (see below), should be reviewed independently by at least 2 technical staff members.

(d) When raising questions the following should be considered: − Each essay question will have a time allowance of 20 minutes.

− A complete A4 side is provided for each question and answer, if required the answer can be extended onto the reverse side of the page.

− The question should be such that the answer expected will be at the level shown for that subject in the module syllabus.

− The question should not be ambiguous but should seek a broad reply rather than be limited in scope for answer.

− The question should lend itself to be written in a technical report style, in a logical sequence (beginning, middle and end), containing the applicable and relevant technical words needed in the answer.

− Do not ask for drawings/sketches to support the essay.

Powered by EASA eRules Page 560 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) SECTION B — PROCEDURES FOR COMPETENT AUTHORITIES − The question should be relevant to the category and level of difficulty listed in the syllabus, e.g. a description of a typical general aviation system may not be acceptable for a typical commercial aeroplane.

− Subject to obvious constraints in relation to the topic being addressed the question should have a strong bias towards the practical maintenance of a system/component and the answer should show an understanding of normal and deteriorated conditions of an aircraft and its systems.

Variations on alternative possible answers which have not been thought of, may have to be taken into account to aid the examiner when marking. If considered relevant, the model answer should be amended to include these new points.

(e) Because of the difficulty in marking an essay answer using key points only, there is a need for the way in which the report was written to be assessed and taken into consideration.

(f) The total points for each question will add up to 100 and will need to reflect both the combination of the technical (key point) element and the report style element.

(g) Each key point will be graded upon its importance and have point weighting allocated to it. The total weight will represent 60% of the mark.

(h) Key points are the ‘important elements’ that may be knowledge or experience - based and will include other maintenance orientated factors such as relevant safety precautions or legislative practices if applicable. Excessive reference to the need for MM r eferral or safety checks may be considered wasteful.

(i) The question answer will be analysed for the clarity and manner in which the essay report is presented and have a weighting allocated to it which will represent 40% of the mark.

(j) The answer should show the candidate's ability to express himself in technical language.

This includes readability of the language, basic grammar and use of terminology.

(k) The report starts in the beginning and has logical process to reach a conclusion.

(l) Supporting diagrams should not be encouraged but if used should supplement the answer and not replace the need for a broad text answer.

(m) The report should not be indexed, itemised or listed.

(n) Within reason the candidate should not be penalised for incorrect spelling.

(o) A zero mark should only be given in exceptional circumstances. Even if the student misunderstands the question and gives an answer to a different question, a sympathetic mark even if only for the report style should be given, this could up to the maxim um percentage allowed.

(p) The two allocated marks should be added together and written into the answer paper.

(q) If a question answer resulting in a borderline failure is principally due to ‘written report errors,’ the paper should be discussed and the mark agreed if possible with another examiner.

GM1 66.B.400(d) General

ED Decision 2023/019/R In the case of a person applying for the issue or change of an AML, by use of examination credits, to a competent authority of a Member State (hereafter referred to as licensing authority) other than the competent authority that has granted the examination credits (hereafter referred to as competent authority), the licensing authority is expected to contact the competent authority and request the examination credit assessment or the credit report or any other information and documentation it considers neces sary in order to ascertain the equivalence of the syllabus of the technical qualification obtained by the applicant to the syllabus of the basic knowledge modules.

The competent authority is expected to provide the licensing authority with all the requested information regarding its examination crediting system and the applicant concerned.

Should the licensing authority observe any inconsistency in the provided documentation or have doubts regarding the equivalence of the technical qualification of the applicant to the syllabus of the basic knowledge modules, it is expected to address the competent aut hority and arrive at a mutual understanding.

The licensing authority is also expected to assess the application against its own credit report and equivalence criteria in order to ensure a standardised approach to the process of examination crediting, and fair treatment to all its applicants.

Unless proven that the examination credits granted by the competent authority were not in compliance with the provisions of the Regulation, or that a positive assessment of the applicant’s documentation would hinder its own examination crediting system, th e licensing authority is expected to consider the applicant’s documentation as compliant.

The final decision regarding the consideration of the provided documents as valid supporting documentation in respect of point 66.B.100 or 66.B.110 rests with the licensing authority.

1. General Regulation (EU) 2023/989 1.1. All basic examinations shall be carried out using the multi - choice question format and essay questions as specified below. The incorrect alternatives shall seem equally plausible to anyone ignorant of the subject. All of the alternatives shall be clearly r elated to the question and of similar vocabulary, grammatical construction and length. In numerical questions, the incorrect answers shall correspond to procedural errors such as corrections applied in the wrong sense or incorrect unit conversions: th ey shall not be mere random numbers.

1.2. Each multi - choice question shall have three alternative answers of which only one shall be the correct answer and the candidate shall be allowed a time per module which is based upon a nominal average of 75 seconds per question.

1.3. Each essay question requires the preparation of a written answer and the candidate shall be allowed 20 minutes to answer each such question.

1.4. Suitable essay questions shall be drafted and evaluated using the knowledge syllabus in Appendix I Module 7 .

1.5. Each question will have a model answer drafted for it, which will also include any known alternative answers that may be relevant for other subdivisions.

1.6. The model answer will also be broken down into a list of the important points known as Key Points.

1.7. The pass mark for each module and sub - module multi - choice part of the examination is 75 %.

1.8. The pass mark for each essay question is 75 % in that the candidates answer shall contain 75 % of the required key points addressed by the question and no significant error related to any required key point.

1.9. If either the multi - choice part only or the essay part only is failed, then it is only necessary to retake the multi - choice or essay part, as appropriate.

1.10. Penalty marking systems shall not be used to determine whether a candidate has passed.

1.11. An examination in a module may not be retaken earlier than 90 days following the date of a failed examination in that module, except in the case of a maintenance training organisation approved in accordance with Annex IV (Part - 147) which delivers a course of retraining tailored to the failed subjects in the particular module; the failed module may be retaken after 30 days.

1.12. Basic knowledge examinations with a maximum allowed time of more than 90 or more than 180 minutes may be split in two or three partial exams respectively.

Each partial exam shall: (a) be complementary to the other partial exam or exams taken by the candidate, ensuring that the combination of partial exams meets the examination requirements for the subject module; (b) be of similar allowed time; (c) be passed with 75 % or more of the questions answered correctly; (d) contain a number of questions that is multiple of four; Powered by EASA eRules Page 631 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) APPENDICES TO ANNEX III (Part - 66) (e) be listed on the same certificate of recognition issued after the last partial exam has been successfully passed. That certificate of recognition shall list the dates and the results of the partial exams – without averaging the results; (f) be taken within the same organisation, following the normal examination provisions for retaking failed exams.

1.13. The maximum number of attempts for each examination is three in a 12 - month period.

The applicant shall provide in a written statement to the approved maintenance training organisation or the competent authority to which they apply for an examination, the number, and dates of attempts during the 12 months preceding the examination, and th e organisation or the competent authority where those attempts took place. The approved maintenance training organisation or the competent authority is responsible for checking the number of attempts within the applicable time frames .

1.14 While it is accepted that the subject matter of the questions may be the same, the questions used as part of the MBT learning programme shall not be used in examinations.

AMC1 Appendix III Aircraft type training and type evaluation

standard — on - the - job training (OJT) Section 1

ED Decision 2023/019/R Aircraft Type Training 1. Aircraft type training may be sub - divided in airframe and/or powerplant and/or avionics/electrical systems type training courses.

− Airframe type training course means a type training course including all relevant aircraft structure and electrical and mechanical systems excluding the powerplant.

− Powerplant type training course means a type training course on the bare engine, including the build - up to a quick engine change unit.

− The interface of the engine/airframe systems should be addressed by either airframe or powerplant type training course. In some cases, such as for general aviation, it may be more appropriate to cover the interface during the airframe course due to the lar ge variety of aircraft that can have the same engine type installed.

− Avionics/electrical systems type training course means type training on avionics and electrical systems covered by but not necessarily limited to ATA (Air Transport Association) Chapters 22, 23, 24, 25, 27, 31, 33, 34, 42, 44, 45, 46, 73 and 77 or equivalent.

2. Practical training may be performed either following or integrated with the theoretical elements. However, it should not be performed before theoretical training.

3. The content of the theoretical and practical training should: − address the different parts of the aircraft which are representative of the structure, the systems/components installed and the cabin; and − include training on the use of technical manuals, maintenance procedures and the interface with the operation of the aircraft.

Therefore it should be based on the following elements: − Type design including relevant type design variants, new technology and techniques; − Feedback from in - service difficulties, occurrence reporting, etc; − Significant applicable airworthiness directives and service bulletins; − Known human factor issues associated with the particular aircraft type; − Use of common and specific documentation, (when applicable, such as MMEL, AMM, MPD, TSM, SRM, WD, AFM, tool handbook), philosophy of the troubleshooting, etc.; − Knowledge of the maintenance on - board reporting systems and ETOPS maintenance conditions where applicable; − Use of special tooling and test equipment and specific maintenance practises including critical safety items and safety precautions; Powered by EASA eRules Page 668 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) APPENDICES TO ANNEX III (Part - 66) − Significant and critical tasks/aspects from the MMEL, CDL, Fuel Tank Safety (FTS), airworthiness limitation items (ALI) including Critical Design Configuration Control Limitations (CDCCL), CMR and all ICA documentation such as MRB, MPD, SRM, AMM, etc., whe n applicable.

− Maintenance actions and procedures to be followed as a consequence of specific certification requirements, such as, but not limited to, RVSM (Reduced Vertical Separation Minimum) and NVIS (Night Vision Imaging Systems); − Knowledge of relevant inspections and limitations as applicable to the effects of environmental factors or operational procedures such as cold and hot climates, wind, moisture, sand, de - icing / anti - icing, etc.

The type training does not necessarily need to include all possible customer options corresponding to the type rating described in the Appendix I to AMC to Part - 66 .

4. Limited avionic system training should be included in the category B1 type training as the B1 privileges include work on avionics systems requiring simple tests to prove their serviceability.

5. Electrical systems should be included in both categories of B1 and B2 type training.

6. The theoretical and practical training should be complementary and may be: − integrated or split; − s upported by the use of training aids, such as trainers, virtual aircraft, aircraft components, maintenance simulation training devices (MSTDs) and maintenance training devices (MTDs) .

7. The integration and usage of MSTDs and MTDs, as defined in AMC 147.A.30(a), in maintenance type training (theoretical and/or practical) should consider the following: − The use of actual aircraft components should be allowed for any MSTD or MTD, even if the components are in a non - airworthy condition.

− The complexity and degree of simulation for an MSTD may vary and should support type training elements that address a component, a system or the entire aircraft. Based on its characteristics and capabilities, the MSTD may be: − a training device capable of providing, for the respective component or system, the representation of aircraft location, access and layout, and for servicing with an acceptable level of accuracy and limited simulation; or − a training device capable of providing, for the respective component or system, the representation of aircraft location, access and layout with sufficient accuracy and with interactive simulation for servicing, and the applicable maintenance data for oper ational (O) and functional (F) test elements including built - in test (BIT) initiation and monitoring from outside the cockpit; such representation should have the capability to accommodate some troubleshooting scenarios; or − a training device capable of providing, for the respective component or system, the representation of onboard (flight deck/cockpit or cabin) indication and controls with an acceptable level of accuracy and limited interactive simulation; or − a training device capable of providing, for the respective component or system, the representation of onboard (flight deck/cockpit or cabin) indication and controls with sufficient accuracy and with interactive simulation for servicing, and the applicable maintenance data for operational (O) and functional (F) test elements Powered by EASA eRules Page 669 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) APPENDICES TO ANNEX III (Part - 66) including built - in test (BIT) initiation and monitoring; such representation should have the capability to accommodate some troubleshooting scenarios; or − any combination of the above.

− Flight simulation training devices (FSTDs) may be used as MSTDs whenever their characteristics and capabilities are considered appropriate for, and supportive of, the delivery of the respective maintenance training element(s).

− An MTD is any training device other than an MSTD used for maintenance training and/or examination and/or assessment.

‘Aircraft Type Training and Examination Standard. On - the - Job

Training’

ED Decision 2015/029/R Practical Element of the Aircraft Type Training 1. The practical training may include instruction in a classroom or in simulators but part of the practical training should be conducted in a real maintenance or manufacturer environment.

2. The tasks should be selected because of their frequency, complexity, variety, safety, criticality, novelty, etc. The selected tasks should cover all the chapters described in the table contained in paragraph 3.2 of Appendix III to Part - 66 .

3. The duration of the practical training should ensure that the content of training required by paragraph 3.2 of Appendix III to Part - 66 is completed.

Nevertheless, for aeroplanes with a MTOM equal or above 30000kg, the duration for the practical element of a type rating training course should not be less than two weeks unless a shorter duration meeting the objectives of the training and taking into acco unt pedagogical aspects (maximum duration per day) is justified to the competent authority.

4. The organisation providing the practical element of the type training should provide trainees a schedule or plan indicating the list of tasks to be performed under instruction or supervision. A record of the tasks completed should be entered into a logb ook which should be designed such that each task or group of tasks may be countersigned by the designated assessor. The logbook format and its use should be clearly defined.

5. In paragraph 4.2 of Appendix III to Part - 66 , the term ‘designated assessors appropriately qualified’ means that the assessors should demonstrate training and experience on the assessment process being undertaken and be authorised to do so by the organisation.

Further guidance about the assessment and the designated assessors is provided in Appendix III to AMC to Part - 66 .

6. The practical element (for powerplant and avionic systems) of the Type Rating Training may be subcontracted by the approved Part - 147 organisation under its quality system according to the provisions of 147.A.145(d)3 and the corresponding Guidance Material.

ED Decision 2015/029/R Differences Training Approved difference training is not required for different variants within the same aircraft type rating (as specified in Appendix I to AMC to Part - 66 ) for the purpose of type rating endorsement on the aircraft maintenance licence.

However, this does not necessarily mean that no training is required before a certifying staff authorisation can be issued by the maintenance organisation (refer to AMC 66.A.20(b)3 ).

GM1 Appendix III Aircraft type training and type evaluation

standard — on - the - job training (OJT) Section 1(c)

ED Decision 2023/019/R DIFFERENCES TRAINING If the holder of a B1 and B2 licence, without any type rating, successfully completes a combined type training course (B1 + B2) followed by an OJT tailored only to B1 tasks, they can obtain only the type - rating endorsement that is applicable to the B1 subc ategory.

Within the next 3 years from the completion of the combined training course, endorsement of the aircraft type for the B2 category is possible after carrying out an OJT programme limited to the tasks relevant to the B2 category only.

When instead, the aircraft type endorsement would be requested after more than 3 years, the applicant would be required to also pass a differences type training course (from B1 to B2) plus the OJT programme limited to the tasks relevant to the B2 category only. All common theoretical and practical elements, and OJT tasks, already demonstrated as B1, shall be considered fulfilled.

AMC1 Appendix III Aircraft type training and type evaluation

standard — on - the - job training (OJT) Section 3

ED Decision 2023/019/R AIRCRAFT TYPE TRAINING STANDARD Training methods are categorised as ‘instructor - centred’, ‘student - centred’ and ‘blended training’.

The actual training method and the training tools should be adapted to suit the training subject and be chosen considering their intrinsic characteristics, such as but not limited to their efficiency and the pedagogical benefits of the method/tool.

A complex or critical subject should not normally be taught solely through a student - centred method unless provisions are in place to verify the actual and progressive acquisition of knowledge of the student.

Complex and critical areas should be identified by the training needs analysis (TNA). The complexity and criticality of the areas could differ on a case - by - case basis (that is, areas proven to be critical by organisations’ ‘in - service events’, occurrence r eporting, human factors, safety, etc.), but should in any case cover the maintenance areas with special emphasis (MASE) identified by the type - certificate holder (TCH) in its operational suitability data (OSD).

AMC1 Appendix III Aircraft type training and type evaluation – on -

the - job training (OJT) Section 3.1(d)

ED Decision 2023/019/R Training n eeds a nalysis (TNA) for the t heoretical e lement of the a ircraft t ype t raining 1. The minimum duration for the theoretical element of the type rating training course, as described in Appendix III to Part - 66 , has been determined based on: − generic categories of aircraft and minimum standard equipment fit − the estimated average duration of standard courses imparted in Europe 2. The purpose of the Training Needs Analysis (TNA) is to adapt and justify the duration of the course for a specific aircraft type. This means that the TNA is the main driver for determining the duration of the course, regardless of whether it is above or below the minimum duration described in Appendix III to Part - 66 .

In the particular case of type training courses approved on the basis of the requirements valid before Regulation (EU) No 1149/2011 was applicable (1 August 2012) and having a duration for the theoretical element equal to or above the minimum duration cont ained in paragraph 3.1(c) of Appendix III to Part - 66 , it is acceptable that the TNA only covers the differences introduced by Regulation (EU) No 1149/2011 in paragraph 3.1(e) ‘Content’ and the criteria introduced in paragraph 3.1(d) ‘Justification of course duration’ related to the minimum attendance and th e maximum number of training hours per day. This TNA may result in a change in the duration of the theoretical element.

3. The content and the duration deriving from this TNA may be supported by an analysis from the Type Certificate holder.

4. In order to approve the reduction of such minimum duration, the competent authority should perform an assessment on a case - by - case basis, and the assessment should be appropriate to the aircraft type and to the training methods and tools proposed.

For example: (a) While it would be exceptional for a theoretical course for a large transport category aircraft, such as an A330 or a B777, to be below the minimum duration shown, it would not necessarily be exceptional in the case of a business aircraft, such as a Lea rjet 45 or similar. The TNA for a business aircraft course could demonstrate that a course of a shorter duration satisfies the applicable requirements.

(b) The use of an MSTD (i.e. flat panel trainer) comprising aircraft - type - specific software may result in the duration of the training being reduced due to a more effective transfer of knowledge.

(c) The use of multimedia - based training (MBT), or blending the training methods, may improve the efficiency of the training and, consequently, contribute to the reduction of the overall time needed to achieve the learning objectives .

5. When developing the TNA , the following should be considered: (a) The TNA should include an analysis identifying all the areas and elements where there is a need for training as well as the associated learning objectives, considering the design philosophy of the aircraft type, the operational environment, the type of operations and the operational experience. This analysis should be written in a manner which provides a Powered by EASA eRules Page 672 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) APPENDICES TO ANNEX III (Part - 66) reasonable understanding of which areas and elements constitute the course in order to meet the learning objectives.

(b) As a minimum, the Training Need Analysis (TNA) should take into account all the applicable elements contained in paragraph 3.1 of Part - 66 Appendix III and associated AMCs.

(c) The TNA should set - up the course content considering the Appendix III objectives for each level of training and the prescribed topics in the theoretical element table contained in paragraph 3.1 of Part - 66 Appendix III .

(d) For each chapter described in the theoretical element table contained in paragraph 3.1 of Part - 66 Appendix III , the corresponding training time should be recorded.

(e) Typical documents to be used in order to identify the areas and elements where there is a need for training typically include, among others, the Aircraft Maintenance Manual, MRB report, CMRs, airworthiness limitations, Troubleshooting Manual, Structural Repair Manual, Illustrated Parts Catalogue , Airworthiness Directives and Service Bulletins.

(f) During the analysis of these documents: − Consideration should be given to the following typical activities: − Activation/reactivation; − Removal/Installation; − Testing; − Servicing; − Inspection, check and repairs; − Troubleshooting / diagnosis.

− For the purpose of identifying the specific elements constituting the training course, it is acceptable to use a filtering method based on criteria such as: − Frequency of the task; − Human factor issues associated to the task; − Difficulty of the task; − Criticality and safety impact of the task; − In - service experience; − Novel or unusual design features (not covered by Part - 66 Appendix I ); − Similarities with other aircraft types; − Special tests and tools/equipment.

− It is acceptable to follow an approach based on: − Tasks or groups of tasks, or − Systems or subsystems or components (g) The TNA should: − Identify the learning objectives for each task, group of tasks, system, subsystem or component; Powered by EASA eRules Page 673 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) APPENDICES TO ANNEX III (Part - 66) − Associate the identified tasks to be trained to the regulatory requirements (table in Paragraph 3.1 of Appendix III to Part - 66 ); − Organise the training into modules in a logical sequence (adequate combination of chapters as defined in Appendix III of Part - 66 ); − Determine the sequence of learning (within a lesson and for the whole syllabus); − Identify the scope of information and level of detail with regard the minimum standard to which the topics of the TNA should be taught according to the set - up objectives.

− Address the following: − Description of each system/component including the structure (where applicable); − System/component operation taking into account: (a) Complexity of the system (e.g. the need of further break down into subsystems, etc.); (b) Design specifics which may require more detailed presentation or may contribute to maintenance errors; (c) Normal and emergency functioning; (d) Troubleshooting; (e) Interpretation of indications and malfunctions; (f) Use of maintenance publications; (g) Identification of special tools and equipment required for servicing and maintaining the aircraft; (h) Maintenance Practices; (i) Routine inspections, functional or operational tests, rigging/adjustment, etc.

− Describe the following: − The instructional methods and training tools and their blended application in order to ensure the effectiveness of the training .

− The maintenance training documentation/material to be delivered to the student .

− Facilitated discussions, questioning session, additional practice - oriented training, etc.

− The homework, if developed , i.e. to support the achievement of the learning objectives while using asynchronous distance - learning or self - learning methods.

− The training provider’s resources available to the learner.

(h) It is acceptable to differentiate between subjects which have to be led by an instructor and subjects which may be delivered through interactive simulation training devices and/or covered by self - paced elements. The o verall time of the course will be allocated accordingly.

A training hour means 60 minutes of tuition excluding any breaks, examination, revision, preparation and aircraft visit. In excep tional cases, the competent authority may allow deviation from this standard when it is properly justified that the proposed number of hours follows pedagogical and human factors principles. These principles are especially important in those cases where: − Theoretical and practical training are performed at the same time; − Training and normal maintenance duty/apprenticeship are performed at the same time.

(j) The minimum participation time in order for the trainee to meet the objectives of the course should not be less than 90 % of the tuition hours , or 95 % completion of the content in case of student - centred methods in a theoretical training course. Additional training may be provided by the training organisation in order to meet the minimum participation time. If the minimum participation defined for the course is not met, a certificate of recognition should not be issued .

(k) The TNA is a living process and should be reviewed/updated based on operation feedback, maintenance occurrences, airworthiness directives, major service bulletins impacting maintenance activities or requiring new competencies for mechanics, alert servi ce bulletins, feedback from trainees or customer satisfaction, evolution of the maintenance documentation such as MRBs, MPDs, MMs, etc. The frequency at which the TNA should be reviewed/updated is left to the discretion of the organisation conducting the c ourse.

NOTE: The examination is not part of the TNA. However, it should be prepared in accordance with the learning objectives described in the TNA.

AMC1 Appendix III Aircraft type training and type evaluation

standard — on - the - job training (OJT) Section 6

ED Decision 2023/019/R On - the - job training (OJT) General ‘Maintenance organisations appropriately approved according to this Regulation for the maintenance of that aircraft type’ means Part - 145 or Part - CAO approved maintenance organisations (AMO) that hold an ‘A’ rating for such aircraft.

The OJT may be split in several parts and carried out at different AMOs, also combining line and base facilities from the same or different organisations. The organisation at which the final assessment is carried out, should control and coordinate the OJT activities and have the responsibility for the entire OJT programme.

The procedures for the OJT should be included in the Exposition Manual of the approved maintenance organisation.

‘Skills and responsibilities of a typical certifying staff’ include but are not limited to: − understanding the importance of professional integrity, behaviour and having an appropriate attitude towards safety; − understanding the conditions for ensuring the continuing airworthiness of aircraft and components; − the ability to identify and rectify existing and potential unsafe conditions; − the ability to prioritise tasks, coordinate with a team, and report discrepancies; − the ability to determine the required qualifications for the performance of maintenance tasks; − the ability to confirm the proper accomplishment of maintenance tasks; − the ability to compile and control completed work cards; − knowledge of safety risks linked to a particular working environment; − understanding of human performance and limitations; − understanding of the AMO’s (where the OJT is performed) privileges and limitations; − understanding of the AMO’s personnel authorisations and limitations; − being familiar with the AMO’s documents/forms (work packages, work orders, work cards, etc.); − being familiar with AMO’s release - to - service procedures: use of the aircraft technical logbook (ATLB), deferral of items and dispatch under MEL/CDL; − access, use and control of the required tools and equipment; − access, use and control of the required ICAs (AMM, TSM, SRM, etc.).

Powered by EASA eRules Page 676 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) APPENDICES TO ANNEX III (Part - 66) OJT content and OJT logbook If the aircraft manufacturer has defined the OJT tasks during the type certification of a particular aircraft type (e.g. the operational suitability data (OSD) has been approved for a particular aircraft type), those tasks should be selected. In particular , the analysis performed for the maintenance areas of specific emphasis (MASE), as defined in point 430 of CS - MCSD, helps the organisation identify the more appropriate tasks.

Where no such data exists, the task list in Appendix II to the AMC to Annex III (Part - 66) serves as the basis to develop an OJT programme including the applicable tasks for a particular aircraft type, based typically on the AMM. The tasks may be selected from the table in Appendix II in order to cover a broader representative sample of both simple and complex tasks on the particular aircraft type in order to reach a balanced distribution of the tasks between line and base maintenance. The tasks should be selected among those that are applicable to the aircraft type and the licence (sub)category applied for; for example, the selection could exclude location tasks (LOC) and tasks that can be considered under the category A licence privileges (seat covers, boilers, wheels, etc.).

A minimum number of tasks, as described in point 2 ‘List of tasks for OJT’ of Appendix II , of each of the following categories should be performed: INS/inspections, FOT/functional or operational, SGH/servicing, R/I removal and installation, MEL, and T/S troubleshooting. The licensing authority may accept that a limited number of tasks is not p erformed as long as the relevant cross section of the tasks as regards quality, quantity and complexity is still assured.

A task may be performed on the analogous system installed on a different aircraft type when the systems are similar in terms of design architecture, technology, and functionality. This can be the case, for example, for tasks performed on engines or landing gear of aircraft of the same manufacturer.

Such task should be clearly identified and recorded.

Certain maintenance tasks could be performed on non - airworthy aircraft that still maintain functionality of systems to the extent that the maintenance tasks can be completely performed without any deviation from the maintenance instructions. Tasks circumsc ribed to system components may be performed at the workshop. This can be the case, for example, for avionics functional tests.

Such scenarios should be limited to specific tasks that may not occur often in the maintenance of operational aircraft.

The use of MSTDs and MTDs for OJT should be restricted to a minimum.

When an existing licence is changed to include an additional category with a type rating, a different OJT from the category held to the new one may be permissible. In those cases, only tasks corresponding to the differences between the two categories shoul d be performed.

The OJT may be partly performed on aircraft whose maintenance is not subject to Regulation (EU) 2018/1139 (for example, aircraft subject to the FAA regulatory framework or training helicopters used by the military) provided that the maintenance is subject to the same procedures and manuals.

A minimum of maintenance activity on aircraft that are subject to Regulation (EU) 2018/1139 is, however, required in order to gain sufficient insight into the European civil aviation regulatory framework and into release - to - service procedures. The acceptan ce of the OJT is up to the licensing authority.

The organisation that has control over the OJT should provide candidates with a schedule or plan which indicates the list of tasks to be performed under supervision. A record of the completed tasks is to be entered into a logbook whose design and format sh ould be such that each task or group of tasks is countersigned by the corresponding mentor(s).

Regarding day - to - day supervision of the OJT programme in the approved maintenance organisation and the role of the mentor(s), the following should be considered: Powered by EASA eRules Page 677 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) APPENDICES TO ANNEX III (Part - 66) − It is sufficient for the completion of the individual OJT tasks to be confirmed by the direct mentor(s), without the direct evaluation of the assessor being necessary.

− During the day - to - day OJT performance, the aim of the supervision is for mentors to oversee the whole process, including task completion, use of manuals, adherence to procedures, observance of safety measures, warnings, cautions and recommendations, and de monstration of appropriate behaviour in the maintenance environment.

− The mentor(s) should personally observe the work being performed to ensure its safe completion, and should be readily available for consultation if needed during the OJT.

− The mentor(s) should sign the tasks and release the maintenance tasks as the candidate is still not qualified to do so.

− The mentor(s) should be designated by the approved maintenance organisation to supervise.

For training in release - to - service procedures, following the completion of the performance of a specific task chosen by the mentor, the candidate should prepare a document with simulated release to service which has to be marked as ‘for training purposes o nly’ (e.g. ATL page, maintenance task card, CRS). If both the task and the simulated release to service have been performed to the satisfaction of the mentor, the task may be countersigned in the OJT task list by the mentor. A physical or electronic copy o f the document with simulated release should be added to the syllabus.

Tasks which are usually performed with more than one person may be performed by more than one candidate under the supervision of one mentor. During the performance of the tasks, the mentor is limited to overseeing three candidates at the same time, given t hat the candidates can be properly seen ‘at a glance’ from the mentor’s position. Those tasks should be marked as ‘group tasks’ when applying for the approval. All other tasks should be a one - to - one mentorship. In such cases, all the candidates involved sh ould be noted on the work order.

At the end of the performance of the OJT, a compliance report shall be made which verifies and documents the correct and complete performance and the recommendation of the mentor(s) for the following assessment. The mentor(s) may deny a recommendation if t he candidate has not demonstrated the knowledge, skills, behaviour and/or ethics required from certifying staff.

Final assessment of the applicant The OJT assessment should consist of a theoretical part and a practical part.

The theoretical part comprises the regulatory framework, safety procedures, knowledge of aircraft and its systems, maintenance procedures, and other typical certifying staff activities such as: − the review and acceptance of work orders; − shift - handover procedures and team coordination; − communication and interaction with the flight crew; − dispatch with unserviceable items; − clear aircraft logbook entries and reporting notes; − checks before release to service.

The practical part should include maintenance tasks on the aircraft (e.g. rem./inst., TS, R/I, FOT, MEL dispatch). The assessor may decide to simulate some aspects of the maintenance tasks.

A training aircraft may be acceptable. It is good practice to assess the practical skills on the aircraft in question while the assessment of knowledge may be performed either on the aircraft or in theory.

Further guidance about the designated assessors is provided in the AMC to Appendix III to Part - 66.

Basic knowledge modules or partial modules required The purpose of this table is to outline the examinations required to add a new basic category/subcategory to an AML granted i n accordance with this Annex.

The syllabi prepared in accordance with Appendix I and Appendix VII require different levels of knowledge for different licence categorie s within a module; therefore, there are additional examinations applicable to certain modules for licence holders wishing to extend an AML granted in accordance with this Annex to include another category/subcategory and an analysis of the module shall be conducted to determine the subjects miss ing or passed at a lower level.

* Experience may be reduced by 50 % but allowing a licence with limitations, i.e. a licence endorsed with the exclusion of ‘com plex maintenance tasks provided for in Appendix VII to Annex I (Part - M), standard changes provided for in point 21.A.90B of Annex I (Part 21) to Regulation (EU) No 748/2012, and standard repairs provided for in poin t 21.A.431B of Annex I (Part 21) to Regulation (EU) No 748/2012’.

Computer - generated documents need not have all the boxes incorporated when any such box remains blank, so long as the document can clearly be recognised as an aircraft maintenance licence issued in accordance with Annex III (Par t - 66).

3. The document may be filled in either in English or the official language of the Member State of the competent authority. In the latter case, a second copy in English shall be attached to the document for any licence holder who needs to use the licence outs ide that Member State to ensure understanding for the purpose of mutual recognition.

4. Each licence holder shall have a unique licence holder number, established on the basis of a national identifier and an alpha - numeric designator.

5. The document may have the pages in a different order to the one of this example and needs not have some or any divider lines as long as the information contained is positioned in such a manner that each page lay - out can clearly be identified with the forma t of the example of the aircraft maintenance licence contained herein.

6. The document shall be prepared by the competent authority. However, it may also be prepared by any maintenance organisation approved in accordance with Annex II (Part - 145) , where the competent authority agrees to this and the preparation takes place in accordance with a procedure laid down in the maintenance organisation exposition referred to in point 145.A.70 of Annex II (Part - 145). In all cases, the competent authority shall issue the document.

7. The preparation of any change to an existing aircraft maintenance licence shall be carried out by the competent authority.

aspects Final score: Notes: The following shall be taken into account by the competent authority when assessing the MBT against the individual criteria listed in Table (A): Categories : (a) Academic quality The information presented in the multimedia resource shall have two characteristics: i. Reliability: the information is reliable, current, and relatively free of errors. The information complies with the current regulatory requirements.

ii. Relevance: the information is relevant to the learning objectives defined for the course.

It supports the student in achieving the learning objectives.

(b) Pedagogical quality The MBT emphasises the activities which promote the development of the required knowledge and skills.

The main criteria for each product are related to three aspects: i. Pedagogical formulation/construction: it is characterised by the quality of simplification, the presence of summaries as well as the use of diagrams, figures, animations, and illustrations. It evaluates whether the structure of the learning resource promot es its use in a pedagogical context. This refers to the ease of orientation (summary, lesson plan), presence of appropriate interactions, usability (back, forward, scroll boxes, etc.), and communication resources (questions and answers, FAQs, forum, etc .)

ii. Pedagogical strategies: teaching and learning styles should be based on active teaching approaches to build meaningful situations related to learning objectives and to learner motivation.

iii. Student assessment methods: methods are implemented to measure the achievement of learning objectives.

APPENDICES TO AMC TO ANNEX III (P ART - 66)

Appendix I to AMC to Annex III — Aircraft Type Ratings for Part - 66

Aircraft Maintenance Licences

ED Decision 2023/019/R The following aircraft type ratings should be used to ensure a common standard throughout the Member States.

In order to ke ep this list up - to - date, if a Member State needs to issue a type rating that is not included in this list, the information sh ould be passed on to EASA using the EASA ‘Contact us’ webpage ( https://www.easa.europa.eu/contact - us ) .

The tables may erroneously contain aircraft models that fall within the definition of Annex I aircraft of Regulation (EU) 2018/1139. The requirements of Part - 66 do not apply to these aircraft.

Notes on type rating ( TR ) endorsement covering several models/variant s : The endorsement of a type rating (TR) on the aircraft maintenance licenc e (AML), covering several models/variants, does not automatically imply that the AML holder has acquired the appropriate knowledge on each model/variant. In fact, the AML holder may only have received TR training and/or gained experience that was limited to one or several models or variants.

To demonstrate adequate competence on the relevant model(s)/variant(s), the AML holder and/or the maintenance organisation where the AM L holder is contracted/employed is ( are ) responsible to verify that the model/variant has been adequately covered by the TR course or gained experience and is up to date .

Further explanation can be found in AMC 66.A.20(b) 3 and AMC 145.A.35(a) .

Notes on when and how the licences should be modified: The licensing authorities should implement the new type rating list within 6 months after publication of this Decision. During this implementation period, the old type ratings may still be endorsed. New applications for type ratings that are no longer certified by EASA should not be accepted. Licences with the old type ratings shall be endorsed with the amended type ratings, whenever the licensing authority deems necessary or the holder requests it; however, no later than the next renewal of the licence.

T he instructions on how to endorse a modified type rating (for example, in the case of combined or split TRs) are included in the chapter ‘Details of the changes’ of explanatory note of the decision.

Notes on aircraft modified by a Suppl emental Type Certificate (STC): − This Appendix intends to include the type ratings of aircraft resulting from STCs for installation of a different engine. These STCs are those approved by EASA and those approved by the Member States before 2003 and grandfathered by EASA . STCs other than those for engines are not considered.

Example: The STC from J ET AVIATION AG, approved by the LBA for replacement of GE CF 700 by Honeywell TFE731 on Fan Jet Falcon Series E , results in a new rating called ‘ Falcon 20 E (Honeywell TFE731) ’ .

− However, the ratings from STCs for installation of an engine: − on part of the original airframe models, or Powered by EASA eRules Page 728 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) APPENDICES TO AMC TO ANNEX III (Part - 66) − from the same manufacturer, but of a type very similar to the original one, have not been added because they would have resulted in an already existing rating.

E xamples: − The STC from SILVERHAWK CONVERSIONS approved by EASA for installation of PT6A - 135A on Beech C90, C90A and E90 would result in the Beech C90/C90A/E90 (PWC PT6) rating, but this is not listed because it is already included in the original Beech 90 Series (PW C PT6) rating.

− The STC from Air - Service Wildgruber GmbH approved by LBA for replacement of PWC PT6A - 20 by PWC PT6A - 27 would result in the De Havilland DHC - 6 - 100 (PWC PT6) rating, but this is not listed because it is already included in the De Havilland DHC - 6 (PWC PT6) ra ting in the table.

− EASA has not received all the information concerning STCs that have been previously approved by the Member States. As a result, not all STCs are considered by this publication.

− When the STC concerns the installation of an engine that falls under a different subcategory, e.g. replacemen t of a piston engine by a turbo prop (a turbine engine), then the new type rating endoresment requires compliance with all the relevant criteria for basic knowledge, experience, type training, and on - the - job training (OJT) .

− In case a type rating resulting from an STC has not been yet defined by EASA , the latter shall be contacted by the competent authority to agree on a new type rating to be used.

In the following tables: − The table is alphabetically sorted first by TC/STC Holder, then by TR endorsement, and finally by Model.

− The column ‘ TC Holder ’ includes t he TC holder as defined in the type certificate data s heets (TCD S) (EASA, FAA or other) or the specific airworthiness s pecifications (SAS).

− The column ‘ STC Holder ’ includes th e STC holder as defined in the supplemental type certificate data s heets (STCDS) (EASA, FAA or other).

− Some TC holders’ designations have been cor rected to add the information: ‘ Aircraft with an SAS’, this means that the aircraft listed under this TC holder designation is considered to be an ‘orphan aircraft’ or General Aviation aircraft form CIS (former Sovjet Union) countries .

− In Group 3, the column ‘Type of structure’ intends to assist the competent authorities in identifying the experience required for this type with a view t o removing existing limitations on the licence.

− In Group 4, the column ‘Type of structure’ intends to assist the competent authorities in identifying the required ‘L’ subcategories.

− Wooden structure covered with fabric is considered to fall under wooden structure. For aeroplanes with a combination of structures, e.g. metal tubing fuselage and wooden wings, both experiences ‘metal tube covered with fabric’ and ‘wooden structure’ are re quired.

− In Group 3, the column ‘MTOM’ intends to assist the competent authorities in identifying the aeroplane types where the maximum take - off m ass (MTOM) is: − above 2t requires a B1.2 and B2 or B2L licence, or − 2 t and below requires a B1.2 or B3 and B2 or B2L licence.

− ‘OSD Approved’ or ‘Pending OSD Approval’ means that an OSD - MCS (operational suitability data for maintenance certifying staff) exists or is still under the approval process at the date of publication of this ED Decision. OSD data is owned by the TCH (see TCHs contact list: https://www.easa.europa.eu/document - library/operational - suitability - data/osd - contact - list ) .

Type training courses approved bef ore the approval of the OSD - MCS shall include the OSD elements within 2 years after the OSD - MCS approval.

− STC reference number.

− ‘TC ( or STC ) not yet released’ means that the type certificate (or STC) has not yet been released by EASA at the date of publication of this ED Decision , but the final model configuration is sufficiently mature that the type rating endorsement can be already defined. In this case, the initial training and licensing may start and be used for approval of type training courses and Part - 66 licence endorsement. On the contrary, the associated rating for t he maintenance organisation can be granted only after the type certification of the aircraft (or after the approval of the STC) .

66) (Regulation (EU) No 1321/2014) APPENDICES TO AMC TO ANNEX III (Part - 66) 2) List of tasks for OJT The minimum list of tasks should be selected from the table below according to the following procedures and criteria: (i) Filter the ATA chapters (or sub - chapters, when required) applicable to the specific aircraft type (add others if they are missing).

(ii) Identify relevant and significant tasks for each required category of INS, FOT, SGH, R/I, MEL and TS.

(iii) Retain the required percentage for each task category, and throughout ATA chapters, as much as relevant to the particular aircraft type.

The selection of tasks should give precedence to tasks which are critical and complex in terms of: − difficulty to execute; − interpretation of the maintenance procedures / work instructions; − specific tools and equipment; − coordination among maintenance staff (teamwork); − human factors (accessibility, human – machine interface (HMI), etc.); − safety impact on the aircraft and the crew.

Removal and installation tasks include the final confirmation test, if required.

Credit may be given for similar tasks between ATA systems (e.g. pneumatic valves in ATA 21, 30 and 36), but this should be kept to a minimum.

Some tasks may be performed on another aircraft type as long as both the system and the task are similar.

The following table provides an acceptable method of selection of OJT tasks for B1 and B2 AML categories, per ATA chapter or sub - chapters, as required by point 6.2(e) of Appendix III to Annex III.

Appendix III — Evaluation of the competence: assessment and

assessors

ED Decision 2015/029/R This Appendix applies to the competence assessment performed by the designated assessors (and their qualifications).

1) What does ‘competence’ mean and areas of focus for assessment The assessment should aim at measuring the competence by evaluating three major factors associated to the learning objectives: − Knowledge; − Skills; − Attitude; Generally, knowledge is evaluated by examination. The purpose of this document is not to describe the examination process: this material mainly addresses the evaluation of ‘skills’ and ‘attitude’ after training containing practical elements. Nevertheless, the trainee needs to demonstrate to have sufficient knowledge to perform the required tasks.

‘Attitude’ is indivisible from the ‘skill’ as this greatly contributes to the safe performance of the tasks.

The evaluation of the competence should be based on the learning objectives of the training, in particular: − the (observable) desired performance. This covers what the trainee is expected to be able to do and how the trainee is expected to behave at the end of the training; − the (measurable) performance standard that must be attained to confirm the trainee’s level of competence in the form of tolerances, constraints, limits, performance rates or qualitative statements; and − the conditions under which the trainee will demonstrate competence. Conditions consist of the training methods, the environmental, situational and regulatory factors.

The assessment should focus on the competencies relevant to the aircraft type and its maintenance such as, but not limited to: − Environment awareness (act safely, apply safety precautions and prevent dangerous situations); − Systems integration (demonstrate understanding of aircraft systems interaction – identify, describe, explain, plan, execute); − Knowledge and understanding of areas requiring special emphasis or novelty (areas peculiar to the aircraft type, domains not covered by Part - 66 Appendix I , practical training elements that cannot be imparted through simulation devices, etc.); − Using reports and indications (the ability to read and interpret); − Aircraft documentation finding and handling (identify the appropriate aircraft documentation, navigate, execute and obey the prescribed maintenance procedures); − Perform maintenance actions (demonstrate safe handling of aircraft, engines, components and tools); Powered by EASA eRules Page 925 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) APPENDICES TO AMC TO ANNEX III (Part - 66) − Aircraft final/close - up and report (apply close up, initiate appropriate actions/follow - up/records of testing, establish and sign maintenance records/logbooks).

2) How to assess As far as feasible, the objectives of the assessment should be associated with the learning objectives and the passing level; it means that observable criteria should be set in order to measure the performance and should remain as objective as possible.

The general characteristics of effective assessment are: objective, flexible, acceptable, comprehensive, constructive, organised and thoughtful. At the conclusion, the trainee should have no doubt about what he/she did well, what he/she did poorly and how he/she can improve.

The following is a non - exhaustive list of questions that may be posed to assist assessment: − What are the success factors for the job?

− What are typical characteristics of a correct behaviour for the task?

− What criteria should be observed?

− What level of expertise is expected?

− Is there any standard available?

− What is the pass mark? For example: − ‘Go - no go’ situation; − How to allocate poi nts? Minimum amount to succeed; − ‘Must know or execute’ versus ‘Good to know or execute’ versus ‘Don’t expect the candidate to be an expert’.

− Minimum or maximum time to achieve? Use time effectively and efficiently.

− What if the trainee fails? How many times is the trainee allowed to fail?

− When and how should the trainee be prepared for the assessment?

− What proportion of judgment by the instructor out of collaboration with the trainee is needed during the evaluation stage?

The assessment may be: − diagnostic (prior to a course), formative (re - orientate the course on areas where there is a need to reinforce) or summative (partial or final evaluation); − performed task - by - task, as a group of tasks or as a final assessment; One method might be an initial assessment to be performed by the trainee himself, then discussing areas where the perceptions of the trainee’s performance by the assessors differ in order to: − develop the self - assessment habits; − make the assessment more acceptable and understandable to both parties.

A ‘box - ticking’ exercise would be pointless. Experience has shown that assessment sheets have largely evolved over time into assessment of groups of ‘skills’ because in practice such things eventually detracted from the training and assessment that it was intended to serve: evaluate Powered by EASA eRules Page 926 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex III (Part - 66) (Regulation (EU) No 1321/2014) APPENDICES TO AMC TO ANNEX III (Part - 66) at a point of time, encourage and orientate the training needs, improve safety and ultimately qualify people for their duties.

In addition, many other aspects should be appropriately considered during the assessment process such as stress and environmental conditions, difficulty of the test, history of evaluation (such as tangible progresses or sudden and unexpected poor performan ce made by the trainee), amount of time necessary to build competence, etc.

All these reasons place more emphasis on the assessor and highlight the function of the organisation’s approval.

3) Who should assess In order to qualify, the assessor should: − Be proficient and have sufficient experience or knowledge in: − human performance and safety culture; − the aircraft type (necessary to have the certifying staff privileges in case of CRS issuances); − training/coaching/testing skills; − instructional tools to use; − Understand the objective and the content of the practical elements of the training that is being assessed; − Have interpersonal skills to manage the assessment process (professionalism, sincerity, objectivity and neutrality, analysis skills, sense of judgement, flexibility, capability of evaluating the supervisor’s or instructor’s reports, handling of trainee’s r eactions to failing assessment with the cultural environment, being constructive, etc.); − Be ultimately designated by the organisation to carry out the assessment.

The roles may be combined for: − the assessor and the instructor for the practical elements of the Type Rating Training; or − the assessor and the supervisor for the On - the - Job Training.

provided that the objectives associated to each role are clearly understood and that the competence and qualification criteria according to the company’s procedures are met for both functions. Whenever possible (depending on the size of the organisation), it is recommended to split the roles (two different persons) in order to avoid any conflicts of interests.

When the functions are not combined, the role of each function should be clearly understood.

ED Decision 2015/029/R 1. An appropriate selection of aircraft parts means appropriate in relation to the particular subject module or sub - module of Part - 66 being instructed. For example the turbine engine module should require the provision of sufficient parts from different types of turbine engine to show what such parts look like, what the critical areas are from a maintenance viewpoint and to enable disas sembly/assembly exercises to be completed.

2. Appropriate aircraft, engines, aircraft parts and avionic equipment means appropriate in relation to the particular subject module or sub - module of Part - 66 being instructed. For example category B2 avionic training should require amongst other equipment, access to at least one type of installed autopilot and flight director system such that maintenance and system functioning can be observed and therefore mor e fully understood by the student in the working environment.

3. ‘Access’ may be interpreted to mean, in conjunction with the facilities requirement of 147.A.100(d) , that there may be an agreement with a maintenance organisation approved under Part - 145 to access such parts, etc.

147.A.120 Maintenance training material

147.A.130 Training procedures and quality system

Regulation (EU) No 1321/2014 (a) The organisation shall establish procedures acceptable to the competent authority to ensure proper training standards and compliance with all relevant requirements in this Part.

(b) The organisation shall establish a quality system including: 1. an independent audit function to monitor training standards, the integrity of knowledge examinations and practical assessments, compliance with and adequacy of the procedures, and 2. a feedback system of audit findings to the person(s) and ultimately to the accountable manager referred to in point 147.A.105(a) to ensure, as necessary, corrective action.

AMC 1 147.A.130(a) Training procedures and quality system

ED Decision 2023/019/R This guidance material provides some clarifications for the incorporation of new training methods and training technologies in the procedures for aircraft maintenance training.

The classic training method is a teacher lecturing the pupils in a classroom. Commonly the training tools are a blackboard and training manuals. New technologies make it possible to develop new training methods and use other training tools, e.g. multimedia - based training and virtual reality. A combination of several training methods/tools is recommended in order to increase the overall effectiveness of the training.

Simulation cannot be eligible as a sole training or assessment tool for basic hand skills such as wiring, welding, drilling, filing, wire locking, riveting, bonding or any other skill where competence may only be achievable by performing a hands - on activit y.

Three tables are provided to illustrate the possibilities for the use of different training methods and tools: Table 1: Training tools Table 2: Training methods Table 3: Combination of training methods and tools and their use Table 1 lists existing training tools that may be selected for the training.

Table 1: Training tools Training tools Description 1 Slideshow presentation A structured presentation of slides.

2 Manuals Comprehensive and controlled publication of a particular topic.

3 Computer (desktop PC, An electronic processing device that can hold and display information in laptop, etc.) various media.

4 Mobile devices (such as, A mobile electronic processing device that can hold and display but not limited to, tablets, information in various media.

smart phones, etc.)

5 Videos Electronic media for broadcasting moving visual images.

6 MSTD — Maintenance A training device that is intended to be used in maintenance training, simulation training device examination, and/or assessment for a component, system or entire aircraft. The MSTD may consist of hardware and software elements.

8 Virtual reality A computer - generated three - dimensional (3D) environment which can be explored and possibly interacted with.

9 MTD — Maintenance Maintenance training device is any training device other than an MSTD training device used for maintenance training and/or examination and/or assessment. It may include mock - ups.

10 Real aircraft A suitable aircraft whose condition allows teaching a selection of maintenance tasks that are representative of the particular aircraft or of the aircraft category.

‘Suitable’ means an aircraft of the type or licence (sub)category (if the licence (sub)category aircraft is outfitted with the same equipment subject to the particular lesson module(s) and is sufficiently similar so that the lesson objective(s) can be sati sfactorily accomplished) for type training, or an aircraft representative of the licence (sub)category for basic training, and excludes ‘virtual aircraft’.

‘Condition’ means that the aircraft is equipped with its main components and that the systems can be activated/operated when this is required by the learning objectives.

11 Aircraft component A suitable aircraft component used to teach specific maintenance tasks off - the - wing. This may include but is not limited to tasks such as borescope inspections, minor repairs, testing, or the assembly/disassembly of sub - components. ‘Suitable’ means that th e condition of the component should fit the learning objectives of the tasks and, when appropriate, may feature existing defects or damages.

12 Augmented reality An enhancement (modification, enrichment, alteration or manipulation) of one’s current perception of reality elements of a physical, real - world environment following user’s inputs picked up by sensors transferred to rapid streaming computer images. By cont rast, virtual reality replaces the real world with a simulated one.

13 Embedded training A maintenance training function that is originally integrated into the aircraft component’s design (i.e. a centralised fault display system).

14 Classroom A physical, appropriate location where learning takes place.

15 Virtual classroom A simulated, not physical, location where synchronous learning takes place.

16 Virtual aircraft A simulated, not physical, aircraft that may be used in theoretical training, practical training, examination or assessment.

Note: Synthetic training devices (STDs) is a generic term used for systems using hardware and/or software, simulating the behaviour of one or more aircraft systems or a complete aircraft, such as maintenance simulation training devices (MSTDs), maintenance training devices (MTDs) and flight simulation training devices (FSTDs) .

Table 2 lists existin g training methods that may be selected for the training.

Computer - CBT is any interactive means of structured training X X X based training using a computer to deliver a content. (Note: Not (CBT) to be confused with competency - based training that also uses the acronym ‘CBT’) Demonstration A method of teaching by example rather than X X explanation.

Distance Distance learning reflects training situations in X X learning which instructors and students are physically asynchronous separated. It is asynchronous if the teacher and the students do not interact at the same time.

Distance Distance learning reflects training situations in X X learning which instructors and students are physically synchronous separated. It is synchronous if the teacher and the students interact at the same time (real time).

e - learning Training via a network or electronic means, with or X X X without the support of instructors (e - tutors).

Lecturing Practice of face - to - face delivery of training and X X (instructor - learning material between an instructor and led/face to face) students, either individuals or groups.

Mobile learning Any sort of learning that happens when the X X X (M - learning) student is not at a fixed, predetermined location, using mobile technologies.

Multimedia - Any combined use of different training media. X X X (4) based training Simulation Any type of training that uses a simulator imitating X X X a real - world process or system.

Web - based Generic term for training or instruction delivered X X X training (WBT) over the internet or an intranet using a web browser.

Note: The purpose of this table is to provide a short definition for each associated training method and to relate each method to the focus of the learning. It is not meant to comprehensively explore and identify the capabilities of each training method herein included.

(1) ‘Instructor - centred’ means that the instructor is responsible for teaching the student.

(2) ‘Student - centred’ means that the student is responsible for the learning progress.

(3) ‘Blended training’ includes different instructional methods and tools, different delivery methods, different scheduling (synchronous/asynchronous) or different levels of guidance. Blended training allows the integration of a range of learning opportuni ties.

(4) ‘Multimedia - based training’ by definition uses various media to achieve its objective, thus, none of the single media listed is per se a complete solution for training.

Table 3 presents the combination of training methods and tools that may be taken into account for theoretical and practical training.

AMC 147.A.130(b) Training procedures and quality system

ED Decision 2015/029/R 1. The independent audit procedure should ensure that all aspects of Part - 147 compliance should be checked at least once in every 12 months and may be carried out as one complete single exercise or subdivided over a 12 - month period in accordance with a scheduled plan.

2. In a small maintenance training organisation the independent audit function may be contracted to another maintenance training organisation approved under Part - 147 or a competent person acceptable to the competent authority. Where the small training organisation chooses to contract the audit function it is conditional on the audit being carried out twice in every 12 month period with one such audit being unannounced .

3. Where the maintenance training organisation is also approved to another Part requiring a quality system, then such quality systems may be combined.

4. When training or examination is carried out under the sub - contract control system: (i) a pre audit procedure should be established whereby the Part - 147 approved maintenance training organisation’ should audit a prospective sub - contractor to determine whether the services of the sub - con tractor meet the intent of Part - 147.

(ii) a renewal audit of the subcontractor should be performed at least once every 12 months to ensure continuous compliance with the Part - 147 standard.

(iii) the sub - contract control procedure should record audits of the sub - contractor and to have a corrective action follow - up plan.

5. The independence of the audit system should be established by always ensuring that audits are carried out by personnel not responsible for the function or procedure being checked.

GM to 147.A.130(b) Training procedures and quality system

ED Decision 2015/029/R 1. The primary objective of the quality system is to enable the training organisation to satisfy itself that it can deliver properly trained students and that the organisation remains in compliance with Part - 147 .

2. The independent audit is a process of routine sample checks of all aspects of the training organisation’s ability to carry out all training and examinations to the required standards. It represents an overview of the complete training system and does not r eplace the need for instructors to ensure that they carry out training to the required standard.

3. A report should be raised each time an audit is carried out describing what was checked and any resulting findings. The report should be sent to the affected department(s) for rectification action giving target rectification dates. Possible rectification d ates may be discussed with the affected department(s) before the quality department confirms such dates on the report. The affected department(s) should rectify any findings and inform the quality department of such rectification.

4. A large training organisation (an organisation with the capacity to provide training for 50 students or more) should have a dedicated quality audit group whose sole function is to conduct audits, raise finding reports and follow up to ensure that findings are being rectified. For the small training organisation (an organisation with the capacity to provide training for less than 50 students) it is acceptable to use competent personnel from one section/department not responsible for the function or proced ure to check the section/department that is responsible Powered by EASA eRules Page 941 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex IV (Part - 147) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS subject to the overall planning and implementation being under the control of the quality manager.

5. The management control and follow up system should not be contracted to outside persons.

The principal function is to ensure that all findings resulting from the independent audit are corrected in a timely manner and to enable the accountable manager to re main properly informed of the state of compliance. Apart from rectification of findings the accountable manager should hold routine meetings to check progress on rectification except that in the large training organisation such meetings may be delegated on a day to day basis to the quality manager as long as the accountable manager meets at least once per year with the senior staff involved to review the overall performance.

147.A.135 Examinations

Regulation (EU) 2023/989 (a) The examination staff shall ensure the security of all questions.

(b) Any student found during a knowledge examination to be cheating or in possession of material pertaining to the examination subject other than the examination papers and associated authorised documentation shall be disqualified from taking the examination a nd may not take any examination for at least 12 months after the date of the incident. The competent authority shall be informed of any such incident together with the details of any enquiry within one calendar month.

(c) Any examiner found during a knowledge examination to be providing question answers to any student being examined shall be disqualified from acting as an examiner and the examination declared void. The competent authority must be informed of any such occurrence within one calendar month.

(d) The examination shall be performed in a controlled environment by a training organisation approved under this Annex and described in its maintenance training organisation exposition (MTOE).

For examination purposes, a ‘controlled environment’ means an environment where the following can be established and verified: (a) the identity of the students; (b) the proper conduct of the examination process; (c) the integrity of the examination and (d) the security of the examination material.

AMC 147.A.135 Examinations

147.A.145 Privileges of the maintenance training organisation

Regulation (EU) 2023/989 (a) The maintenance training organisation may carry out the following as permitted by and in accordance with the maintenance training organisation exposition: (i) basic training courses to the Annex III (Part - 66) syllabus, or part thereof; (ii) aircraft type/task training courses in accordance with Annex III (Part - 66); (iii) the examination of students who attended the basic or aircraft type training course at the maintenance training organisation; (iv) the examination of students who did not attend the aircraft type training course at the maintenance training organisation; (v) the examination of students who did not attend the basic training course at the maintenance training organisation, provided that: (1) the examination is conducted at one of the locations identified in the approval certificate, or (2) if performed at locations not identified in the approval certificate, as permitted by points (b) and (c), either − the examination is provided through a European Central Question Bank (ECQB), or − in the absence of an ECQB, the competent authority selects the questions for the examination; (vi) the issue of certificates in accordance with Appendix III following successful completion of the approved basic or aircraft type training courses and examinations specified in points (a)(i), (a)(ii), (a)(iii), (a)(iv) and (a)(v), as applicable.

(b) Theoretical training, knowledge examinations, practical training and practical assessments may be carried out only at the locations identified in the approval certificate or at any location specified in the MTOE .

(c) By derogation to point (b), the maintenance training organisation may only conduct training, knowledge examinations and practical assessments in locations different from the point (b) locations in accordance with a control procedure specified in the mainte nance training organisation exposition. Such locations need not be listed in the maintenance training organisation exposition.

(d) 1. The maintenance training organisation may subcontract the conduct of basic theoretical training, type training and related examination s to a non maintenance training organisation only when under the control of the maintenance training organisation quality system.

2. The subcontracting of basic theoretical training and examination is limited to Annex III (Part - 66), Appendix I , Modules 1, 2, 3, 4, 5, 6, 8, 9 and 10.

(e) An organisation may not be approved to conduct examinations unless approved to conduct the corresponding training.

(f) By derogation from point (e), an organisation approved to provide basic knowledge training or type training may also be approved to provide type examination in the cases where type training is not required.

AMC1 147.A.145(c) Distance learning via uniform resource locator

(URL) addresses

ED Decision 2023/019/R Distance training may also be delivered via URL addresses. When delivering distance training, the learning location is the responsibility of the student and need not be controlled by the training organisation. Refer to point 147.A.100(j) .

Knowledge examinations may also be conducted by accessing the examination questions via uniform resource locator (URL) addresses, provided the knowledge examination environment is under the control of the maintenance training organisation.

AMC 147.A.145(d) Privileges of the maintenance training

organisation

ED Decision 2015/029/R 1. When training or examination is carried out under the sub - contract control system it means that for the duration of such training or examination, the Part - 147 approval has been temporarily extended to include the sub - contractor. It therefore follows that those parts of the sub - contractor’s facilities, personnel and procedures involved with the Part - 147 approved maintenance training organisation’s students should meet requirements of Part - 147 for the duration of that training or examination and it remains the Part - 147 organisation’s responsibility to ensure such requirements are satisfied.

2 . The maintenance training organisation approved under Part - 147 is not required to have complete facilities and personnel for training that it needs to sub - contract but it should have its own expertise to determine that the sub - contractor meets the Part - 147 standards. Particular attention should be given to ensuring that the training that is delivered also meets the requirements of Part - 66 and the aircraft technologies are appropriate.

3. The contract between the maintenance training organisation approved under Part - 147 and the sub - contractor should contain: − a provision for the Agency and the competent authority to have right of access to the sub - contractor; − a provision for the sub - contractor to inform the Part - 147 approved maintenance training organisation of any change that may affect its Part - 147 approval, before any such change takes place.

GM 147.A.145(d) Privileges of the maintenance training

organisation

ED Decision 2015/029/R 1. The pre audit procedure should focus on establishing compliance with the training and examination standards set out in Part - 147 and Part - 66 .

2. The fundamental reason for allowing a maintenance training organisation approved under Part - 147 to sub - contract certain basic theoretical training courses is to permit the approval of maintenance training organisations, which may not have the capacity to conduct training courses on all Part - 66 modules.

3. The reason for allowing the subcontracting of training modules 1 to 6 and 8 to 10 only is, most of the related subjects can generally also be taught by training organisations not specialised in aircraft maintenance and the practical training element as spe cified in 147.A.200 does not apply to them. On the contrary, training modules 7 and 11 to 17 are specific to aircraft maintenance and include the practical training element as specified in 147.A.200. The intent of the ‘limited subcontracting’ option as specified in 147.A.145 is to grant Part - 147 approvals only to those organisations having themselves at least the capacity to teach on aircraft maintenance specific matters.

GM 147.A.145(d)3 Privileges of the maintenance training

organisation

ED Decision 2015/029/R In the case of type training and examination, the reason for allowing only subcontracting to powerplant and avionic systems is that the related subjects can generally also be imparted by certain organisations specialised in these domains such as the Type C ertificate Holder of the powerplant or the OEMs of these avionics systems. In such a case, the type training course should make clear how the interfaces with the airframe are addressed and by whom (the subcontracted organisation or the Part - 147 organisation itself).

AMC 147.A.145(f) Privileges of the maintenance training

organisation

ED Decision 2015/029/R When an organisation approved to provide basic knowledge training or type training is also approved to provide type examination in the cases where type training is not required, appropriate procedures in the MTOE should be developed and approved, including : − The development and the conduct of the type examination; − The qualification of the examiners and their currency.

In particular, emphasis should be put when such an examination is not regularly conducted or when the examiners are not normally involved in aircraft or activities with technology corresponding to the aircraft type subject to examination. An example would be the case of an organisation providing basic knowledge training only for the B1.1 license. This organisation should justify how they run type examinations for single piston - engine helicopters in the case of a B1.4 licence.

SUBPART B — ISSUE OF AN APPROVAL

Regulation (EU) No 1321/2014 This Subpart provides the requirements to issue or vary the maintenance training organisation approval.

147.B.110 Procedure for approval and changes to the approval

Regulation (EU) No 1321/2014 (a) Upon receipt of an application, the competent authority shall: 1. review the maintenance training organisation exposition; and 2. verify the organisation's compliance with the requirement of Annex IV (Part - 147) .

(b) All findings identified shall be recorded and confirmed in writing to the applicant.

(d) The reference number shall be included on the approval certificate in a manner specified by the Agency.

GM to 147.B.110 Procedure for approval and changes to the

approval

ED Decision 2015/029/R 1. A meeting should be arranged between the applicant and the Member State who issue Part - 147 approvals to determine if the applicant's training activities justify the investigation for issue of Part - 147 approval and to ensure that the applicant understands what needs to be done for Part - 147 approval. This meeting is not intended to establish compliance but rather to see if the activity is a Part - 147 activity.

2. Assuming that the applicant's activities come within the scope of Part - 147 approval, instructions should be sent to the competent authority staff requesting that an audit of the applicant be carried out and when satisfied that compliance has been established, a recommendation for the issue of approval should be submitted to the competent authority staff who grant approval unless these are the same staff. The competent authority should determine how and by whom the audit shall be conducted. For example, if the applicant is a large training organisation, it will be necessary to det ermine whether one large team audit or a short series of small team audits or a long series of single person audits is most appropriate for the particular situation. A further consideration in the case of a combined Part - 145 /147 organisation is the possibility to combine the audits.

3. Where it is intended that the maintenance training organisation may conduct training and examinations away from the maintenance training organisation address(es) in accordance with 147.A.145(c) , then a sample audit should be carried out by the competent authority from time to time of the process to ensure that procedures are followed. For practical reasons such sample audits will need to be carried out when training is being conducted away from the maintenance training organisation address(es).

4. The auditing surveyor should ensure that they are always accompanied throughout the audit by a senior member of the organisation making application for Part - 147 approval. Normally this should be the proposed quality manager. The reason for being accompanied is to ensure that the organisation is fully aware of any findings during the audit. In any case, the proposed quality Powered by EASA eRules Page 956 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex IV (Part - 147) (Regulation (EU) No 1321/2014) SECTION B — PROCEDURES FOR COMPETENT AUTHORITIES manager/senior member of the organisation should be debriefed at the end of the audit visit on the findings made during the audit.

5. There will be occasions when the auditing surveyor may find situations in the applicant's organisation on which he/she is unsure about compliance. In this case, the organisation should be informed about possible non - compliance at the time of audit and the fact that the situation will be reviewed before a decision is made. The organisation should be informed of the decision within 2 weeks of the audit visit in writing if the decision is a confirmation of non - compliance.

If the decision is a finding of bei ng in compliance, a verbal confirmation to the organisation will suffice.

6. A change of name of the maintenance training organisation requires the organisation to submit a new application as a matter of urgency stating that only the name of the organisation has changed including a copy of the organisation exposition with the new n ame. Upon receipt of the application and the organisation exposition, the competent authority should reissue the approval certificate valid only up to the current expiry date.

7. A name change alone does not require the competent authority to audit the organisation, unless there is evidence that other aspects of the maintenance training organisation have changed.

8. A change of accountable manager requires the maintenance training organisation to submit such fact to the competent authority as a matter of urgency together with the amendment to the accountable manager exposition statement.

9. A change of any of the senior personnel specified in 147.A.105(b) requires the maintenance training organisation to submit a Form 4 in respect of the particular person. If satisfied that the qualifications and experience meet the standard required by Part - 147, the competent authority should indicate acceptance in writing to the maintenance training organisation.

10. A change in the maintenance training organisation’s exposition requires the competent authority to establish that the procedures specified in the exposition are in compliance with Part - 147 and then to establish if these are the same procedures intended for use within the training facility.

11. Any change of location of the maintenance training organisation requires the organisation to make a new application to the competent authority together with the submission of an amended exposition. The competent authority should follow the procedure specif ied in 147.B.110(a) and (b) in so far as the change affects such procedure before issuing a new Part - 147 approval certificate.

12. The complete or partial reorganisation of a training organisation should require the re - audit of those elements that have changed.

13. Any additional basic or aircraft type training courses requires the maintenance training organisation to make a new application to the competent authority together with the submission of an amended exposition. For basic training extensions, an additional sample of new examination questions relevant to the modules associated with the extension being sought will be re quired to be submitted. The competent authority should follow the procedure of paragraph 11 in so far as the change affects such procedures unless the competent authority is satisfied that the maintenance training organisation has a well - controlled procedu re to qualify such change when it is not necessary to conduct the audit elements of the paragraph 11 procedure.

GM1 ML.A.201 (e) Responsibilities

ED Decision 2020/002/R COMMERCIAL ATO/DTO According to industry practice, the following are examples of aircraft not considered to be operated by a commercial ATO or a commercial DTO: (a) Aircraft operated by an organisation holding an ATO certificate or a DTO declaration, created with the aim of promoting aerial sport or leisure aviation, on the conditions that: (1) the aircraft is operated by the organisation on the basis of ownership or dry lease; (2) the ATO/DTO is a non - profit organisation; and (3) whenever non - members of the organisation are involved, such flights represent only a marginal activity of the organisation.

(b) Aircraft operated under Part - NCO by its owner together with an ATO or a DTO flight instructor for the purpose of training, when the contract between the owner and the training organisation and the procedures of the training organisation allow it. The c ontinuing airworthiness of such aircraft remains under the responsibility of the owner, or of the CAMO or CAO contracted by the owner, if the owner has elected to contract a CAMO or CAO in accordance with ML.A.201(f) .

(c) Aircraft used for very limited training flights due to the specific configuration of the aircraft and limited need for such flights.

GM1 ML.A.201 (f ) Responsibilities

ED Decision 2020/002/R If an owner (see definition in point ML.1(c)(3) ) decides not to make a contract with a CAMO or CAO, the owner is fully responsible for the proper accomplishment of the corresponding continuing airworthiness management tasks. As a consequence, it is expected that the owner properly and realistically sel f - assesses his or her own competence to accomplish those tasks or otherwise seek the necessary expertise.

GM1 ML.A.201 (h ) Responsibilities

ED Decision 2020/002/R USE OF AIRCRAFT INCLUDED IN AN AOC FOR NON - COMMERCIAL OPERATIONS OR SPECIALISED OPERATIONS As point (h) is not a derogation, points ML.A.201(e) and (f) are still applicable. Therefore, the management of continuing airworthiness of the aircraft by the CAMO or CAO of the AOC holder means that the other operator has established a written contract as per Appendix I to Part - ML with this CAMO or CAO.

ML.A.202 Occurrence reporting

Regulation (EU) 2019/1383 (a) Without prejudice to the reporting requirements set out i n Annex II (Part - 145) and Annex Vc (Part - CAMO), any person or organisation responsible in accordance with point ML.A.201 shall report any identified condition of an aircraft or component which endangers flight safety to: (1) the competent authority designated by the Member State of registry of the aircraft, and, when different to the Member State of registry, to the competent authority designated by the Member State of the operator; Powered by EASA eRules Page 1014 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vb (Part - ML) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS (2) to the organisation responsible for the type design or supplemental type design.

(c) Where the maintenance or the airworthiness review of the aircraft is carried out on the basis of a written contract, the person or the organisation responsible for those activities shall also report any condition referred to in point (a) to the owner o f the aircraft and, when different, to the CAMO or CAO concerned.

AMC1 ML.A.202 Occurrence reporting

ED Decision 2023/013/R Accountable persons or organisations should ensure that the design approval holder (DAH) or the declarant of a declaration of design compliance receives adequate reports of occurrences for that aircraft or component, to enable the DAH or the declarant of a declaration of design compliance to issue appropriate service instructions and recommendations to all owners or operators.

Accountable persons or organisations should liaise with the DAH or the declarant of a declaration of design compliance to determine whether published or proposed service information will resolve a problem or to obtain a solution to a particular problem.

AMC - 20 ‘General Acceptable Means of Compliance for Airworthiness of Products, Parts and Appliances’ provides further details on occurrence reporting (AMC 20 - 8).

ML.A.301 Continuing - airworthiness tasks

GM1 ML.A.3 01 (f ) Continuing airworthiness tasks

During the flight preparation, the flight and the post - flight activities as well as for the aircraft handover, the processes requiring the involvement of maintenance personnel or organisations should be agreed in advance with the operator. The operator should consult as necessary with the person or organisation in charge of the airworthiness of the aircraft.

(b) Depending on the aircraft defect and the status of the maintenance activity performed before the flight, different scenarios are possible and are described below: (1) The aircraft maintenance manual (AMM), or any other maintenance data issued by the DAH or the declarant of a declaration of design compliance , requires that an MCF be performed before completion of the maintenance ordered. In this scenario, a certificate after incomplete maintenance, when in compliance with ML.A.801(f) or 145.A.50(e) , should be issued and the aircraft can be flown for this purpose under its airworthiness certificate.

Commission Regulation (EU) No 965/2012 of 5 October 2012 laying d own technical requirements and administrative procedures related to air operations pursuant to Regulation (EC) No 216/2008 of the European Parliament and of the Co uncil (OJ L 296, 25.10.2012, p. 1) ( https://eur - lex.europa.eu/legal - content/EN/TXT/?qid=1568896271265&uri=CELEX:32012R0965 ) .

Powered by EASA eRules Page 1016 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vb (Part - ML) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS Due to incomplete maintenance, it is advisable to open a new entry into the ML.A.305 aircraft logbook, to identify the need for an MCF. This new entry should contain or refer to, as necessary, data relevant to perform the MCF, such as aircraft limitations and any potential effect on operational and emergency equipment due to incomplete ma intenance, maintenance data reference and maintenance actions to be performed after the flight.

After a successful MCF, the maintenance records should be completed, the remaining maintenance actions finalised and a certificate of release to service (CRS) issued.

(2) Based on its own experience and for reliability considerations and/or quality assurance, an operator, owner, CAO or CAMO may wish to perform an MCF after the aircraft has undergone certain maintenance while maintenance data does not call for such a flight.

Therefore, after the maintenance has been properly carried out, a CRS is issued and the aircraft airworthiness certificate remains valid for this flight.

(3) After troubleshooting of a system on the ground, an MCF is proposed by the maintenance personnel or organisation as confirmation that the solution applied has restored the normal system operation. During the maintenance performed, the maintenance instr uctions are followed for the complete restoration of the system and therefore a CRS is issued before the flight. The airworthiness certificate is valid for the flight. An open entry requesting this flight may be recorded in the aircraft logbook.

After the flight and the corresponding maintenance work, the aircraft can be released to service and continue to operate under its original certificate of airworthiness.

(c) For certain MCFs, the data obtained or verified in flight will be necessary for assessment or consideration after the flight by the maintenance personnel or organisation prior to issuing the maintenance release. For this purpose, when the maintenance s taff cannot perform these functions in flight, it may rely on the crew performing the flight to complete this data or to make statements about in - flight verifications. In this case, the maintenance staff should appoint the crew personnel to play such a rol e on their behalf and, before the flight, brief the appointed crew personnel on the scope, functions and the detailed process to be followed, including required reporting information after the flight and reporting means, in support of the final release to service to be issued by the certifying staff.

AMC1 ML.A.3 02 Aircraft maintenance programme

ED Decision 2023/013/R (a) The aircraft should only be maintained according to a single maintenance programme at a given point in time. Where an owner wishes to change from one programme to another (e.g. from an AMP based on minimum inspection programme (MIP) to an AMP based on the data issued by the DAH or the declarant of a declaration of design compliance ), certain additional maintenance may need to be carried out on the aircraft to implement this transition.

(b) The maintenance programme may take the format of the standard template provided in AMC2 ML.A.302 (EASA Form AMP). This maintenance programme may include several aircraft registrations as long as the maintenance requirements for each registration are clearly identified.

EASA Form AMP, Issue 2

GM 1 ML.A.3 02 Aircraft maintenance programme

ED Decision 2023/013/R The responsibilities associated with maintenance programmes developed in accordance with ML.A.302 are the following: (a) If the owner has contracted a CAMO or CAO in order to manage the continuing airworthiness of the aircraft, this organisation is responsible for developing and approving a maintenance programme which: (1) indicates whether this programme is based on data from the DAH or the declarant of a declaration of design compliance, or based on the MIP described in ML.A.302(d) ; (2) identifies the owner and the specific aircraft, engine, and propeller (as applicable); Powered by EASA eRules Page 1024 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vb (Part - ML) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS (3) includes all mandatory continuing airworthiness information and any additional tasks derived from the assessment of the instructions issued by the DAH or the declarant of a declaration of design compliance ; (4) justifies any deviations from the instructions issued by the DAH or the declarant of a declaration of design compliance; when those instructions are the basis for the AMP development, these deviations should not fall below the requirements of the MIP; and (5) is customised to the particular aircraft type, configuration and operation, in accordance with ML.A.302(c)(5) .

(b) If the owner has not contracted a CAMO or CAO in order to manage the continuing airworthiness of the aircraft, then the owner is responsible for developing and declaring the maintenance programme, assuming full responsibility for its content, and for a ny deviations from the instructions issued by the DAH or the declarant of a declaration of design compliance (ref. ML.A.201(f) and ML.A.302(c)(7) ) and the possible consequences of such deviations. In this case, these deviations do not need to be justified, but are to be identified in the AMP. However, the maintenance programme still needs to comply with the requirements contained in ML.A.302(c) , in particular with the obligation to not fall below the requirements of the MIP and to comply with the mandatory continuing airworthiness information.

(c) The content of the owner - declared maintenance programme cannot be challenged up front either by the competent authority or by the contracted maintenance organisation. This declared maintenance programme is the basis for adequate planning of maintenance , as well as for the ARs and the aircraft continuing airworthiness monitoring (ACAM) inspections in accordance with ML.B.303 . Nevertheless, the maintenance programme will be subject to periodic reviews at the occasion of the AR and, in case of discrepancies, linked with deficiencies in the content of the maintenance programme, the owner shall amend the maintenance programme acc ordingly, as required by ML.A.302(c)(9) .

(d) When the competent authority is notified of deficiencies linked with the content of the declared maintenance programme for a particular aircraft (in case no agreement is reached between the owner and the AR staff about the changes required in the maint enance programme), the competent authority should contact the owner, request a copy of the maintenance programme, decide which amendment to the AMP is necessary and raise the associated finding (ref. ML.A.302(c)(9) ). If necessary, the competent authority may also react in accordance with ML.B.304 . Based on the information received, the reported deficiencies and the identified risks, the competent authority may in addition adapt the ACAM programme accordingly (ref. ML.B.303 ).

(e) Although there is no requirement for the owner to send a copy of the maintenance programme to the competent authority, this does not prevent the competent authority from requesting at any time the owner to send information about, or a copy of the AMP, even if deficiencies have not been reported (see AMC1 ML.B.201 ).

(f) Since the maintenance programme has to identify the alternatives tasks to the instructions issued by the DAH or the declarant of a declaration of design compliance , the ARs and ACAM inspections can place emphasis on the inspection of the areas affected by those deviations in order to make sure that the maintenance programme is effective.

(g) Since the competent authority is not responsible for the content of a declared maintenance programme, the competent authority does not authorise the accomplishment of the scheduled maintenance to deviate from the AMP content (other than the tolerances provided for in ML.A.302(d)(1) ). In such cases, the owner may declare an amended AMP.

AMC 1 ML.A.3 02 (c) Aircraft maintenance programme

ED Decision 2023/013/R When evaluating an alternative to a maintenance task issued or recommended by the DAH or the declarant of a declaration of design compliance, such as the extension of TBO intervals, or when considering not to include a maintenance task issued or recommended by the DAH or the declarant of a declaration of design compli ance, a risk - based approach should be taken, considering aspects such as the operation of aircraft, type of aircraft, hours and years in service, maintenance of the aircraft, compensating measures, redundancy of components, etc .

The following table provides more details of aspects that should be considered: Examples OPS approval HIGHER RISK: commercial operation, commercial flight training MEDIUM RISK: flight training by an association, non - commercial specialised operations (SPO) LOWER RISK: private Flight rules HIGHER RISK: instrument flight rules (IFR) MEDIUM RISK: visual flight rules (VFR) at night LOWER RISK: VFR by day Aircraft weight HIGHER RISK: Other than ELA1 MEDIUM RISK: ELA1 aircraft other than light sport aeroplanes (LSA), very light aircraft (VLA), sailplanes and powered sailplanes LOWER RISK: LSA, VLA, sailplanes and powered sailplanes Who manages the HIGHER RISK: owner airworthiness of the LOWER RISK: CAMO/CAO aircraft?

It may also be useful for the owner in o rder to take an informed decision before introducing deviations from the recommendations issued by the DAH or the declarant of a declaration of design compliance . Nevertheless, as allowed by ML.A.302(c)(7) and explained in GM ML.A.302, when the owner issues a declaration for the maintenance programme, it does not need to justify such deviations.

AMC1 ML.A.3 02 (c)(9) Aircraft maintenance programme

ED Decision 2023/013/R ANNUAL REVIEW OF THE AMP (a) During the annual review of the maintenance programme, as required by point ML.A.302(c)(9), the following should be taken into consideration: (1) the results of the maintenance performed during that year, which may reveal that the current maintenance programme is not adequate; (2) the results of the AR performed on the aircraft, which may reveal that the current maintenance programme is not adequate; (3) revisions introduced on the documents affecting the programme basis, such as the ML.A.302(d) MIP or the data issued by the DAH or the declarant of a declaration of design compliance ; (4) changes in the aircraft configuration, and type and specificity of operation; (5) changes in the list of pilot - owners; and (6) applicable mandatory requirements for compliance with Part 21 or Part 21 Light , such as airworthiness directives (ADs), airworthiness limitations, certification maintenance requirements and specific maintenance requirements contained in the type certificate data sheet (TCDS) or airworthiness data sheet (for aircraft subject to a declaration of design compliance) .

To this end, he or she should receive the records of all the maintenance performed during that year from the owner/CAMO/CAO.

(c) When reviewing the results of the maintenance performed during that year and the results of the AR, attention should be paid as to whether the defects found could have been prevented by introducing in the maintenance programme certain recommendations issued by the DAH or the declarant of a declaration of design compliance , which were initially disregarded by the owner, CAMO or CAO.

GM 1 ML.A.3 02 (c) (2)(b) Aircraft maintenance programme

ED Decision 2023/013/R ‘DAH’ refers to the holder of a type certificate (TC), restricted type certificate, supplemental type certificate (STC), European Technical Standard Order (ETSO) authorisation, repair or change to the type design.

‘Declarant’ refers to the natural of legal person who has submitted a declaration of design compliance in accordance with Part 21 Light.

The ‘instructions for continuing airworthiness (‘ICA’) issued by the design approval holder (‘DAH’)’ or the declarant do not include the data issued by another original equipment manufacturer (OEM), except when the ICA issued by the DAH or the declarant ma ke clear reference to such OEM data.

Tasks or intervals (e.g. escalations) alternative to those of the ICA issued by the DAH or the declarant and selected by the CAMO or CAO for the AMP do not need to be approved by the competent authority. Justification of these deviations are to be kept by the CAMO or CAO .

GM 1 ML.A.3 02 (c) (3) Aircraft maintenance programme

ED Decision 2023/013/R ALTERNATIVE MAINTENANCE ACTIONS ‘Maintenance actions alternative to those referred to in point (c)(2)(b)’ refer to when the ICA issued by the DAH or the declarant of a declaration of design compliance are used as the basis for the AMP development and the CAMO, CAO or owner (as applicable), when developing the AMP, decides to dev iate from certain of these instructions issued by the DAH or the declarant of a declaration of design compliance, introducing, for example, a less frequent interval than or a different task type (inspection instead of check) from the one established by the ICA .

These alternative maintenance actions shall not be less restrictive than those set out in the applicable MIP. This means that the extent of the maintenance to be covered by the deviating task cannot be less than the extent of the corresponding task in the MIP in terms of frequency and task type.

Remark: the above does not apply to one - time interval extensions, for which ML.A.302(d)(1) provides 1 - month or 10 - h tolerance (i.e. permitted variation) for aeroplanes, touring motor gliders (TMGs) and balloons and 1 - month tolerance for sailplanes and powered sailplanes other than TMGs.

GM 1 ML.A.3 02 (c) (4 ) Aircraft maintenance programme

ED Decision 2023/013/R MANDATORY CONTINUING AIRWORTHINESS INFORMATION OTHER THAN ADS ‘Mandatory continuing airworthiness information’ other than ADs may be different from one aircraft to an other, depending on the type certification basis used. The aircraft may have been certified before the term ‘ALS (Airworthiness Limitations Section)’ w as introduced in the certification specification (or airworthiness code). However, the intent is that the AMP (whether based on MIP or not) includes all mandatory scheduled maintenance requirements identified during the initial airworthiness activity, by t he TC holder, STC holder , declarant of a declaration of design compliance and, if applicable, engine TC holder. These requirements may be identified under a variety of designations such as: − Airworthiness limitations or Airworthiness limitation items (ALI) − Certification maintenance requirements (CMR) − Safe life items or safe life limits or safe life limitations − Life - limited parts (LLP) − Time limits − Retirements life − Mandatory Inspections or Mandatory Airworthiness Inspections − Fuel airworthiness limitations or Fuel tank safety limitations Powered by EASA eRules Page 1029 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vb (Part - ML) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS In case of doubt, it is advised to check the TCDS or airworthiness data sheet or contact the DAH or the declarant of a declaration of design compliance .

The intervals of the mandatory continuing airworthiness information cannot be extended by a CAMO/CAO. The escalation of such tasks is to be approved by the Agency.

AMC 1 ML.A.3 02 (d ) Aircraft maintenance programme

ED Decision 2021/009/R This AMC contains an acc eptable MIP for aeroplanes of 2 730 kg maximum take - off mass (MTOM) and below, and for ELA2 aircraft other than rotorcraft or airships, grouped in the following categories: − aeroplanes of 2 730 kg MTOM and below; − ELA2 sailplanes and ELA2 powered sailplanes; and − ELA2 balloons.

These MIPs already comply with the requirements of ML.A.302(d) and may be used in order to define the basic information for the maintenance programme as required by ML.A.302(c)(2)(a) . However, the maintenance programme must be customised as required by ML.A.302(c)(5), which may be achieved by using the standard template contained in AMC ML.A.302.

It should be noted that using the 1 - month tolerance permitted by ML.A.302(d)(1) for the annual inspection may result in an expired ARC.

MIP for aeroplanes of 2 730 kg MTOM and below To be performed at every annual/100 - h interval, whichever comes first.

A tolerance of 1 month or 10 h may be applied. The next interval shall be calculated from the time the inspection takes place.

Note 1: Use the manufacturer’s maintenance manual to accomplish each task/inspection.

Note 2: Proper operation of backup or secondary systems and components should be performed wherever a check for improper installation/operation is carried out.

Aeroplanes of 2 730 kg MTOM and below System/component/area Task and inspection detail GENERAL General Remove or open all necessary inspection plates, access doors, fairings, and cowlings. Clean the aircraft and aircraft engine as required.

AMC 1 ML.A. 501(e) Classification and installation

ED Decision 2020/002/R BALLOONS Baskets, burners and fuel cylinders are components which are often interchanged between different balloons. Furthermore, they are often removed/installed by the pilot - owner (or by other persons when such removal/installation is not considered maintenance because the task is described in the AFM).

As a consequence, an EASA Form 1 does not need to be issued when these components are removed in serviceable condition from a balloon, and can be installed on another balloon as long as the person performing the installation has access to the appropriate m aintenance records necessary to establish their serviceable condition. In particular, due attention should be paid to the inspection dates of the various components.

This does not supersede the requirement to release any maintenance performed on such components either on an EASA Form 1 or equivalent or on the balloon maintenance log book, as applicable.

AMC1 ML.A. 801 Aircraft certificate of release to service

ED Decision 2023/013/R AIRCRAFT CERTIFICATE OF RELEASE TO SERVICE (CRS) AFTER EMBODIMENT OF A STANDARD CHANGE OR A STANDARD REPAIR (SC/SR) 1. Release to service and eligible persons Only natural or legal persons entitled to release to service an aircraft after maintenance (see ML.A.801(b) ) are considered as an eligible installer responsible for the embodiment of a SC/SR when in compliance with applicable requirements.

Since the design of the SC/SR does not require specific approval, the natural or legal person releasing the embodiment of the change or repair takes the responsibility that the applicable certification specifications within CS - STAN are fulfilled while bein g in compliance with Part - ML/ Part - M Subpart F/Part - CAO and/or Part - 145 and not in conflict with the data issued by the TC holder or the declarant of a declaration of design compliance . This includes responsibility in respect of an adequate design, the sel ection/manufacturing of suitable parts and their identification, documenting the change or repair, generation or amendment of aircraft manuals and instructions as needed, embodiment of the change/repair, releasing the aircraft to service and record - keeping.

Depending on its nature, for certain SCs/SRs, CS - STAN might restrict the eligibility for the issuance of the release to service to certain persons (e.g. standard change/repair not suitable for release to service by the pilot - owner).

NOTE: Until 1 October 2020 (ref. entry into force of Commission Regulation (EU) 2018/1142), it is possible to have aircraft maintenance released to service by the holder of an appropriate certifying staff qualification valid in a Member State (national qua lification). In this case, the following conditions apply: − If the holder signs the release to service on behalf of a maintenance organisation, this release is valid regardless of the Member State where the aircraft is registered.

− If the holder signs the release to service as an independent certifying staff, this release is only valid in the Member State responsible for such certifying staff qualification and where the aircraft is registered.

2. Parts and appliances to be installed as part of a SC/SR The design of the parts and appliances to be used in a SC/SR is considered a part of the change/repair, and, therefore, there is no need of a specific design approval. However, it is possible that for a particular SC, these certification specifications spe cifically require the use of parts and appliances that meet a technical standard. In this case, when the parts and appliances are required to be authorised as an ETSO article, other articles recognised as equivalent by means of an international safety agre ement or grandfathered in accordance with Regulation (EU) No 748/2012 are equally acceptable.

However, in the case that the change or repair would contain such a part, it should be produced by an approved production organisation (POA holder), and delivered with an EASA Form 1. An arrangement in accordance with 21.A.122(b) is not applicable.

Eligibility for installation of parts and appliances belonging to a SC/SR is subject to compliance with the Part 21, Part 21 Light and Part - ML and maintenance - organisation - related provisions, and the situation varies depending on the aircraft in/on which t he SC/SR is to be embodied, and who the installer is. The need for an EASA Form 1 is addressed in Part 21, Part 21 Light and Part - ML, while less restrictive rules may, for instance, apply for ELA1 and ELA2 aircraft parts (e.g.

21.A.307) and sailplane parts (e.g. AMC 21.A.303 of the ‘AMC and GM to Part 21’) or point 21L.A.193 of Part 21 Light . Furthermore, Part - M Subpart F, Part - CAO and Part - 145 contain provisions (i.e. M.A.603(c) , CAO.A.020(c) and 145.A.42(c) ) that allow maintenance organisations to fabricate certain parts to be installed in/on the aircraft as part of their maintenance activities.

3. Identification of parts and appliances The parts modified or installed during the embodiment of the SC/SR need to be permanently marked in accordance with Part 21 Subpart Q or Part 21 Light Subpart Q .

4. Documenting the SC/SR and declaring compliance with the certification specifications In accordance with Part - ML, Part - M Subpart F, Part - CAO or Part - 145 (e.g. ML.A.801(e) , M.A.612 , CAO.A.065 and 145.A.50(b) ), the legal or natural person responsible for the embodiment of a change or a repair should compile details of the work accomplished. In the case of SCs/SRs, this includes, as necessary, based on the complexity, an engineering file containing drawings, a list of the parts and appliances used for the change or repair, supporting analysis and the results of tests performed or any other evidence suitable to show that the design fulfils the applicable certification specifications within CS - STAN together with a statement of compliance and amendments to aircraft manuals, to instructions for continuing airworthiness and to other documents such as aircraft parts list, wiring diagrams, etc. as deemed necessary. The EASA Form 123 is prepared for the purpose of docume nting the preparation and embodiment of the SC/SR.

The aircraft logbook should contain an entry referring to EASA Form 123; both EASA Form 123 and the release to service required after the embodiment of the SC/SR should be signed by the same person.

EASA Form 123 and all the records listed on it should follow elementary principles of controlled documentation, e.g. contain reference number of documents, issue dates, revision numbers, name of persons preparing/releasing the document, etc.

In addition, ML.A.305 requires that the aircraft owner (or CAMO or CAO, if a contract in accordance with ML.A.201 exists) keeps the status of the changes/repairs embodied in/on the aircraft in order to control the aircraft configuration and manage its cont inuing airworthiness.

With regard to SCs/SRs, the information provided to the owner, CAMO or CAO may be listed in EASA Form 123 and should include, as required, a copy of any modified aircraft manual and/or instructions for continuing airworthiness. All this information should normally be consulted Powered by EASA eRules Page 1056 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vb (Part - ML) (Regulation (EU) No 1321/2014) SECTION A — TECHNICAL REQUIREMENTS when the aircraft undergoes an AR, and, therefore, a clear system to record the embodiment of SCs/SRs, which is also easily traceable, would be of help during subsequent aircraft inspections.

6. Instructions for continuing airworthiness (ICA) As stipulated in ML.A.302 , the aircraft owner, CAMO or CAO needs to assess if the changes in the ICA of the aircraft require the amendment of the AMP.

7. Embodiment of more than one SC The embodiment of two or more related SCs described in Subpart B of CS - STAN is permitted as a single change (the use of one EASA Form 123 only) as long as adequate references to and records of all SCs embodied are captured. Restrictions and limitations of the two (or more) SCs would apply. It is permitted to issue a single release to service containing adequate traceability of all the SCs embodied.

Appendix I I — Limited Pilot - owner maintenance

Regulation (EU) 2019/1383 In addition to the requirements laid down in this Annex, the pilot - owner shall comply with the following basic principles before it carries out any maintenance task: (a) Competence and responsibility (1) The pilot - owner shall always be responsible for any maintenance he performs.

(2) The pilot - owner shall hold satisfactory level of competence to perform the task. It is the responsibility of a pilot - owner to familiarise himself with the standard maintenance practices for his aircraft and with the AMP.

(b) Tasks The Pilot - owner may carry out simple visual inspections or operations to check the airframe, engines, systems and components for general condition, obvious damage and normal operation.

A maintenance task shall not be released by the pilot - owner if any of the following conditions occurs: (1) it is a critical maintenance task; (2) it requires the removal of major components o r a major assembly; (3) it is carried out in compliance with an AD or an airworthiness limitation item (ALI) unless specifically allowed in the AD or the ALI; (4) it requires the use of special tools or calibrated tools (except for torque wrench and crimping tool); (5) it requires the use of test equipment or special testing (e.g. non - destructive testing (NDT), system tests or operational checks for avionics equipment); (6) it is composed of any unscheduled special inspections (e.g. heavy - landing check); (7) it affects systems essential for the instrumental flight rules (IFR) operations; (8) it is a complex maintenance task in accordance with Appendix III, or it is a component maintenance task in accordance with point (a) or (b) of point ML.A.502 ; (9) it is part of the 100 - h/annual check (for those cases the maintenance task is combined with the airworthiness review performed by maintenance organisations or independent certifying staff).

The criteria referred to in points (1) to (9) cannot be overridden by less restrictive instructions issued in accordance with the AMP referred to in point ML.A.302 .

Any task described in the aircraft flight manual (or other operational manuals), for example preparing the aircraft for flight (assembling the sailplane wings, or performing a preflight inspection, or assembling a basket, burner, fuel cylinders and an enve lope combination for a balloon, etc.), is not considered a maintenance task and, therefore, does not require a CRS.

Nevertheless, the person assembling those parts is responsible for ensuring that those parts are eligible for installation and in a servicea ble condition.

(c) Performance and records of the pilot - owner maintenance tasks The maintenance data, as specified in point ML.A.401 , must always be available during the conduct of pilot - owner maintenance and must be complied with. Details of the data referred to Powered by EASA eRules Page 1076 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vb (Part - ML) (Regulation (EU) No 1321/2014) APPENDICES TO ANNEX Vb (Part - ML) in the conduct of pilot - owner maintenance must be included in the CRS in accordance with point (d) of point ML.A.803 .

The pilot - owner must inform the contracted CAMO or CAO (if such contract exists) about the completion of the pilot - owner maintenance tasks no later than 30 days after completion of these tasks in accordance with point (a) of point ML.A.305 .

AMC 1 to Appendix II to Part - ML — Limited pilot - owner

maintenance

ED Decision 2023/013/R (a) The lists below specifies items that may be expected to be completed by an owner who holds a current and valid pilot licence for the aircraft type involved and who meets the competence and responsibility requirements of Appendix II to Part - ML.

(b) The list of tasks may not address in a detailed manner the specific needs of the various aircraft categories. In addition, the development of technology and the nature of the operations undertaken by these categories of aircraft may not always be adequ ately considered.

(d) Therefore, the following lists are considered to meet the representative scope of limited pilot - owner maintenance referred to in ML.A.803 and Appendix II to Part - ML: (1) Part A applies to aeroplanes; (2) Part B applies to rotorcraft; (3) Part C applies to sailplanes and powered sailplanes; and (4) Part D applies to balloons and airships.

(e) Inspection tasks/checks of any periodicity included in an approved maintenance programme can be carried out provided that the specified tasks are compliant with the basic principles of Appendix II to Part - ML.

The content of periodic inspections/checks, as well as their periodicity, is not regulated or standardised in an aviation specification. It is the decision of the DAH or the declarant of a declaration of design compliance to recommend a schedule for each s pecific type of inspection/check .

For an inspection/check with the same periodicity for different aircraft, the content may differ and in some cases, may be critically safety - related and need the use of special tools or knowledge and thus, not qualify for pilot - owner maintenance. Therefore , the maintenance carried out by the pilot - owner should not be generalised to specific inspections such as of a 50 - h, 100 - h or 6 - month periodicity.

The inspections to be carried out are limited to those areas and tasks listed in this AMC to Appendix II; this allows flexibility in the development of the maintenance programme and does not limit the inspection to certain specific periodic inspections. A 50 - h/6 - month periodic inspection for a fixed - wing aeroplane as well as the 1 - year inspection for a glider may normally be eligib le for pilot - owner maintenance.

Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) GENERAL

A NNEX V C (P ART - CAMO)

GENERAL

GM1 to Annex Vc (Part - CAMO) Definitions

ED Decision 2022/011/R For the purpose of the AMC & GM to Part - CAMO, the following definitions are used: Audit refers to a systematic, independent, and documented process for obtaining evidence, and evaluating it objectively to determine the extent to which requirements are complied with.

Note: Audits may include inspections.

Alternative are those means that propose an alternative to an existing AMC or those that propose new means of means to establish compliance with Regulation (EU) 2018/1139 and its delegated and compliance implementing acts for which no associated AMC have been adopted by the Agency.

(AltMoC) Assessment in the context of management system performance monitoring, continuous improvement and oversight, refers to a planned and documented activity performed by competent personnel to evaluate and analyse the achieved level of performance and maturity in relatio n to the organisation’s policy and objectives.

Remark: For ‘risk assessment’, please refer to the definition below.

Base Ref. AMC1 145.A.10 maintenance Competency is a combination of individual skills, practical and theoretical knowledge, attitudes, training, and experience.

Correction is the action to eliminate a detected non - compliance.

Corrective is the action to eliminate or mitigate the root cause(s) and prevent the recurrence of an action existing detected non - compliance, or other undesirable conditions or situations. Proper determination of the root cause(s) is crucial for defining effective corrective actio ns to prevent reoccurrence.

Error is an action or inaction by a person that may lead to deviations from accepted procedures or regulations.

Note: Errors are often associated with occasions where a planned sequence of mental or physical activities either fails to achieve its intended outcome, or is not appropriate with regard to the intended outcome, and when results cannot be attributed purely to chance.

Hazard is a condition or an object with the potential to cause or contribute to an aircraft incident or accident.

Powered by EASA eRules Page 1092 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) GENERAL Human refers to human capabilities and limitations which have an impact on the safety and performance efficiency of aeronautical activities.

Note: Inspection may be part of an audit (e.g. product audit), but may also be conducted outside the normal audit plan; for example, to verify closure of a particular finding.

Just Culture Ref. Regulation (EU) No 376/2014, Article 2.

Line Ref. AMC1 145.A.10 maintenance Near - miss is an event in which an occurrence to be mandatorily reported according to Regulation (EU) No 376/2014 was narrowly averted or avoided.

Example: A CAMO staff on rechecking his/her work at the end of a task realises that an AD, AWL, CMR task was not properly processed (for instance, in the AMP or continuing airworthiness record system) which would have led to a situation that the AD/AWL/CMR would not have been performed on time on the affected (fleet of) aircraft.

Organisational is a condition that affects the effectiveness of safety risk controls, related to the culture, factor policies, processes, resources, and workplace of an organisation.

Oversight refers to the time frame within which all areas of the approval and all processes should be planning cycle reviewed by the competent authority by means of audits and inspections.

Oversight refers to the detailed oversight schedule that defines the number of audits and inspections, programme the scope and duration of each audit and inspection, including details of product audits and locations, as appropriate, to be performed by the competent authority, and the tentative time frame for performing each audit and inspection.

Post holder means the person nominated in accordance with point CAMO.A.305(b)(2) .

Preventive is the action to eliminate the cause of a potential non - compliance, or other undesirable action potential situation.

Risk assessment is an evaluation based on engineering and operational judgement and/or analysis methods in order to establish whether the achieved or perceived risk is acceptable or tolerable.

Safety Culture is an enduring set of values, norms, attitudes, and practices within an organisation concerned with minimising the exposure of the workforce and the general public to dangerous or hazardous conditions. In a positive safety culture, a shared concern for, co mmitment to, and accountability for safety is promoted.

Safety risk refers to the predicted probability and severity of the consequences or outcomes of a hazard.

Safety training refers to dedicated training to support safety management policies and processes, including human factors training.

Powered by EASA eRules Page 1093 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) GENERAL Note: Safety management training refers to specific training for the staff involved in safety management functions in accordance with point CAMO.A.305(a)(5) or CAMO.A.200(a)(3) Working days refer to days between and including Monday to Friday not including public holidays.

AMC1 CAMO.A.125(d)(3) Terms of approval and privileges

ED Decision 2020/002/R SUBCONTRACTING OF CONTINUING AIRWORTHINESS TASKS (a) The CAMO may subcontract certain continuing airworthiness management tasks to qualified organisations. The subcontracted organisation performs the continuing airworthiness management tasks as an integral part of the CAMO’s management system, irrespecti ve of any other approval held by the subcontracted organisation (including CAMO or Part - 145 approval).

(b) The CAMO remains accountable for the satisfactory completion of the continuing airworthiness management tasks irrespective of any contract that may be established.

(c) In order to fulfil this responsibility, the CAMO should be satisfied that the actions taken by the subcontracted organisation meet the standards required by Part - CAMO. Therefore, the CAMO management of such activities should be accomplished: (1) by active control through direct involvement; and/or (2) by endorsing the recommendations made by the subcontracted organisation.

(d) In order to retain ultimate responsibility, the CAMO should limit subcontracted tasks to the activities specified below: (1) airworthiness directive analysis and planning; (2) service bulletin analysis; (3) planning of maintenance; (4) reliability monitoring, engine health monitoring; (5) maintenance programme development and amendments; (6) any other activities, which do not limit the CAMO responsibilities, as agreed by the competent authority.

Powered by EASA eRules Page 1098 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) SECTION A — ORGANISATION REQUIREMENTS (e) The CAMO’s controls associated with subcontracted continuing airworthiness management tasks should be reflected in the associated contract and be in accordance with the CAMO policy and procedures defined in the CAME. When such tasks are subcontracted, the management system is considered to be extended to the subcontracted organisations.

(f) With the exception of engines and auxiliary power units, contracts would normally be limited to one organisation per aircraft type for any combination of the activities described in Appendix II. Where contracts are made with more than one organisation, the CAMO should demonstrate that adequate coordination controls are in place and that the individuals’ responsibilities are clearly defined in the related contracts.

(g) Contracts should not authorise the subcontracted organisation to subcontract to other organisations elements of the continuing airworthiness management tasks.

(h) The competent authority should exercise oversight of the subcontracted activities through the CAMO approval. The contracts should be acceptable to the competent authority. The CAMO should only subcontract to organisations which are specified by the compete nt authority on EASA Form 14 .

(i) The subcontracted organisation should agree to notify the CAMO of any changes affecting the contract as soon as practical. The CAMO should then inform its competent authority. Failure to do so may invalidate the competent authority’s acceptance of the contract.

(j) Appendix II to AMC1 CAMO.A.125(d)(3) provides information on the subcontracting of continuing airworthiness management tasks.

GM1 CAMO.A.125(e) Terms of approval and privileges

ED Decision 2020/002/R (a) An organisation may be approved for the privileges of point CAMO.A.125(d) only, without the privilege to carry out airworthiness reviews. In this case, the airworthiness review can be contracted to another appropriately approved organisation. It is not mandatory that this contracted organisation is linked to an AOC holder, and it is possible to contract an appropriately approved independent CAMO which is approved for the same aircraft type.

(b) In order to be approved for the privileges of point CAMO.A.125(e) for a particular aircraft type, it is necessary to be approved for the privileges of point CAMO.A.125(d) for that aircraft type.

(c) Nevertheless, this does not necessarily mean that the organisation needs to be currently managing an aircraft type in order to be able to perform airworthiness reviews on that aircraft type. The organisation may be performing only airworthiness reviews on an aircraft type without having any customer under contract for that type.

(d) Furthermore, this situation should not necessarily lead to the removal of the aircraft type from the organisation approval. As a matter of fact, since in most cases the airworthiness review staff are not involved in continuing airworthiness management activities, it cannot be argued that these airworthiness review staff are going to lose their skills just because the organisation is not managing a particular aircraft type. The important issue in relation to maintaining a particular aircraft type in the organisation approval is whether the organisation continuously fulfils all the Part - CAMO requirements (facilities, documentation, qualified personnel, management system, etc.) required for initial approval.

ED Decision 2022/017/R FINDINGS RELATED TO THE CAMO’S MANAGEMENT SYSTEM THAT IS HARMONISED WITH THE MANAGEMENT SYSTEM OF ANOTHER APPROVED ORGANISATION If a finding that is raised by the competent authority (or non - compliance that is detected by the compliance monitoring function) affects the harmonisation of the management system of the CAMO with the management system of the contracting operator(s), whic h is required by point M.A.201(ea) , the CAMO should inform the operator(s) to ensure that proper actions are taken within the group.

The CAMO and operator(s) should agree on the appropriate channel for such communication.

If the group use common standards to facilitate the harmonisation of the organisations’ management systems, the CAMO should inform the group management board or similar group governance body.

GM1 CAMO.A.150 Findings

ED Decision 2020/002/R CAUSAL ANALYSIS (a) It is important that the analysis does not primarily focus on establishing who or what caused the non - compliance, but on why it was caused. Establishing the root cause or causes of a non - compliance often requires an overarching view of the events and circumstances that led to it, to identify all the possible systemic and contributing factors (regulatory, human factors (HF), organisational factors, technical, etc.) in addition to the direct factors.

Such an inappropriate or partial causal analysis often leads to defining ‘quick fixes’ that only address the symptoms of the non - conformity. A peer review of the results of the causal analysis may increase its reliability and objectivity.

(c) A system description of the organisation that considers the organisational structures, processes and their interfaces, procedures, staff, equipment, facilities and the environment in which the organisation operates, will support both effective causal ( reactive) a nd hazard (proactive) analyses.

GM1 CAMO.A.200 Management system

ED Decision 2020/002/R GENERAL Safety management seeks to proactively identify hazards and to mitigate the related safety risks before they result in aviation accidents and incidents. Safety management enables an organisation to manage its activities in a more systematic and focused man ner. When an organisation has a clear understanding of its role and contribution to aviation safety, it can prioritise safety risks and more effectively manage its resources and obtain optimal results.

The principles of the requirements in points CAMO.A.200 , CAMO.A.202 , CAMO.A.205 and the related AMC constitute the EU management system framework for aviation safety management. This framework addresses the core elements of the ICAO safety management system (SMS) framework Powered by EASA eRules Page 1107 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) SECTION A — ORGANISATION REQUIREMENTS defined in Appendix 2 to Annex 19, and it promotes an integrated approach to the management of an organisation. It facilitates the introduction of the additional safety management components, building upon the existing management system, rather than adding them as a separate framework.

Integration will remove any duplication and exploit synergies by managing safety risks acr oss multiple activities. Organisations may determine the best means to structure their management systems to suit their business and organisational needs.

The core part of the management system framework ( CAMO.A.200 ) focuses on what is essential for safety management, by mandating the organisation to: (a) clearly define accountabilities and responsibilities; (b) establish a safety policy and the related safety objectives; (c) implement safety reporting procedures in line with just culture principles; (d) ensure the identification of aviation safety hazards entailed by its activities, ensure their evaluation, and the management of associated risks, including: (1) taking actions to mitigate the risks; (2) verifying the effectiveness of the actions taken to mitigate the risks; (e) monitor compliance, while considering any additional requirements that are applicable to the organisation; (f) keep their personnel trained, competent, and informed about significant safety issues; and (g) document all the key management system processes.

Compared to the previous Part - M Subpart G quality system ‘framework’, the new elements that are introduced with Part - CAMO are, in particular, those addressed under points (b) to (d). Points (c) and (d)(1) address component 2 ‘Safety Risk Management’ of the ICAO SMS framework. Points (d)(2) and (e) address component 3 ‘Safety Assurance’ thereof.

Point CAMO.A.200 defines the following as key safety management processes; these are further specified in the related AMC and GM: − Hazard identification; − Safety risk management; − Internal investigation; − Safety performance monitoring and measurement; − Management of change; − Continuous improvement; − Immediate safety action and coordination with the aircraft operator’s Emergency Response Plan (ERP).

Powered by EASA eRules Page 1108 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) SECTION A — ORGANISATION REQUIREMENTS It is important to recognise that safety management will be a continuous activity, as hazards, risks and the effectiveness of safety risk mitigations will change over time.

These key safety management processes are supported by a compliance monitoring function as an integral part of the management system for safety. Most aviation safety regulations constitute generic safety risk controls established by the ‘regulator’. Theref ore, ensuring effective compliance with the regulations during daily operations and independent monitoring of compliance are fundamental to any management system for safety. The compliance monitoring function may, in addition, support the follow - up of safe ty risk mitigation actions. Moreover, where non - compliances are identified through internal audits, the causes will be thoroughly assessed and analysed. Such an analysis in return supports the risk management process by providing insights into causal and c ontributing factors, including HF, organisational factors and the environment in which the organisation operates. In this way, the outputs of compliance monitoring become some of the various inputs to the safety risk management functions. On the other hand , the safety risk management processes may be used to determine focus areas for compliance monitoring. In this way, internal audits will inform the organisation’s management of the level of compliance within the organisation, whether safety risk mitigation actions have been implemented, and where corrective or preventive action is required. The combination of safety risk management and compliance monitoring should lead to an enhanced understanding of the end - to - end process and the process interfaces, exposi ng opportunities for increased efficiencies, which are not limited to safety aspects.

As aviation is a complex system with many organisations and individuals interacting together, the primary focus of the key safety management processes is on the organisational processes and procedures, but it also relies on the humans in the system. The or ganisation and the way in which it operates can have a significant impact on human performance. Therefore, safety management necessarily addresses how humans can contribute both positively and negatively to an organisation’s safety outcomes, recognising th at human behaviour is influenced by the organisational environment.

It is further recognised that the introduction of processes for hazard identification and risk assessment, mitigation and verification of the effectiveness of such mitigation actions will create immediate and direct costs, while related benefits are someti mes intangible and may take time to materialise. Over time, an effective management system will not only address the risks of major occurrences, but also identify and address production inefficiencies, improve communication, foster a better organisation cu lture, and lead to more effective control of contractors and suppliers. In addition, through an improved relationship with the authority, an effective management system may result in a reduced oversight burden.

AMC1 CAMO.A.200(a)(1 ) Management system

ED Decision 2021/009/R ORGANISATION AND ACCOUNTABILITIES (a) The management system should encompass safety by including a safety manager, and a safety review board in the organisational structure. The functions of the safety manager are those defined in AMC1 CAMO.A.305(a)(4);(a)(5) .

(b) Safety review board (1) The safety review board should be a high - level committee that considers matters of strategic safety in support of the accountable manager’s safety accountability.

(2) The board should be chaired by the accountable manager and composed of the person or group of persons nominated under point CAMO.A.30 5 (a) and (b).

(3) The safety review board should monitor: (i) safety performance against the safety policy and objectives; (ii) that any safety action is taken in a timely manner; and (iii) the effectiveness of the organisation’s management system processes.

(4) The safety review board may also be tasked with: (i) reviewing the results of compliance monitoring; (ii) monitoring the implementation of related corrective and preventive actions.

(c) The safety review board should ensure that appropriate resources are allocated to achieve the established safety objectives.

(d) The safety manager or another person designated by the safety manager may attend, as appropriate, safety review board meetings. He or she may communicate to the accountable manager all information, as necessary, to allow decision - making based on safety data.

(e) Notwithstanding point (a), where justified by the size of the organisation and the nature and complexity of its activities and subject to a risk assessment and agreement by the competent authority, the organisation may not need to establish a formal sa fety review board. In this case, the tasks normally allocated to the safety review board should be allocated to the safety manager.

GM1 CAMO.A.200(a)(1) Management system

ED Decision 2020/002/R SAFETY ACTION GROUP (a) Depending on the size of the organisation and the nature and complexity of its activities, a safety action group may be established as a standing group or as an ad hoc group to assist, or act on behalf of the safety manager or the safety review board.

(b) More than one safety action group may be established, depending on the scope of the task and the specific expertise required.

(c) The safety action group usually reports to, and takes strategic direction from, the safety review board, and may be composed of managers, supervisors and personnel from operational areas.

(d) The safety action group may be tasked with or assist in: Powered by EASA eRules Page 1110 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) SECTION A — ORGANISATION REQUIREMENTS (1) monitoring safety performance; (2) defining actions to control risks to an acceptable level; (3) assessing the impact of organisational changes on safety; (4) ensuring that safety actions are implemented within agreed timescales; (5) reviewing the effectiveness of previous safety actions and safety promotion.

GM2 CAMO.A.200(a)(1) Management system

ED Decision 2020/002/R MEANING OF THE TERMS ‘ACCOUNTABILITY’ AND ‘RESPONSIBILITY’ In the English language, the notion of accountability is different from the notion of responsibility.

Whereas ‘accountability’ refers to an obligation which cannot be delegated, ‘responsibility’ refers to an obligation that can be delegated.

AMC1 CAMO.A.200(a)(2) Management system

ED Decision 2020/002/R SAFETY POLICY & OBJECTIVES (a) The safety policy should: (1) reflect organisational commitments regarding safety, and its proactive and systematic management, including the promotion of a positive safety culture; (2) include internal reporting principles, and encourage personnel to report continuing airworthiness - related errors, incidents and hazards; (3) recognise the need for all personnel to cooperate with the compliance monitoring and internal investigations referred to under point (c) of AMC1 CAMO.A.200( a)(3) ; (4) be endorsed by the accountable manager; (5) be communicated, with visible endorsement, throughout the organisation; and (6) be periodically reviewed to ensure it remains relevant and appropriate for the organisation.

(b) The safety policy should include a commitment to: (1) comply with all applicable legislation, to meet all the applicable requirements, and adopt practices to improve safety standard; (2) provide the necessary resources for the implementation of the safety policy.

(3) apply HF principles; (4) enforce safety as a primary responsibility of all managers; and (5) apply ‘just culture’ principles to internal safety reporting and the investigation of occurrences and, in particular, not to make available or use the information on occurrences: (i) to attribute blame or liability to front line staff or other persons for actions, omissions or decisions taken by them that are commensurate with their experience and training; or Powered by EASA eRules Page 1111 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) SECTION A — ORGANISATION REQUIREMENTS (ii) for any purpose other than the maintenance or improvement of aviation safety.

(c) Senior management should continually promote the safety policy to all personnel, demonstrate its commitment to it, and provide necessary human and financial resources for its implementation.

(d) Taking due account of its safety policy, the organisation should define safety objectives. T he safety objectives should: (1) form the basis for safety performance monitoring and measurement ; (2) reflect the organisation ’s commitment to maintain or continuously improve the overall effectiveness of the management system ; (3) be communicated throughout the organisation; and (4) be periodically reviewed to ensure they remain relevant and appropriate for the organisation .

GM1 CAMO.A.200(a)(2) Management system

ED Decision 2020/002/R SAFETY POLICY (a) The safety policy is the means whereby the organisation states its intention to maintain and, where practicable, improve safety levels in all its activities and to minimise its contribution to the risk of an aircraft accident or serious incident as far as is reasonably practicable. It reflects the management’s commitment to safety, and should reflect the organisation’s philosophy of safety management, as well as be the foundation on which the organisation’s management system is built. It serves as a rem inder of ‘how we do business here’. The creation of a positive safety culture begins with the issuance of a clear, unequivocal policy.

(b) The commitment to apply ‘just culture’ principles forms the basis for the organisation’s internal rules describing how ‘just culture’ principles are guaranteed and implemented.

(c) For organisations having their principal place of business in a Member State, Regulation (EU) No 376/2014 defines the ‘just culture’ principles to be applied (refer in particular to Article 16(11) of that Regulation).

AMC1 CAMO.A.200(a)(3) Management system

ED Decision 2020/002/R SAFETY MANAGEMENT KEY PROCESSES (a) Hazard identification processes (1) A reporting scheme for both reactive event and proactive hazards should be the formal means of collecting, recording, analysing, acting on, and generating feedback about hazards and the associated risks that may affect safety.

(2) The identification should include: (i) hazards that may be generated from HF issues that affect human performance; and (ii) hazards that may stem from the organisational set - up or the existence of complex operational and maintenance arrangements (such as when multiple organisations are contracted, or when multiple levels of contracting/subcontracting are included).

Powered by EASA eRules Page 1112 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) SECTION A — ORGANISATION REQUIREMENTS (b) Risk management processes (1) A formal safety risk management process should be developed and maintained that ensures that there is: (i) analysis (e.g. in terms of the probability and severity of the consequences of hazards and occurrences); (ii) assessment (in terms of tolerability); and (iii) control (in terms of mitigation) of risks to an acceptable level.

(2) The levels of management who have the authority to make decisions regarding the tolerability of safety risks, in accordance with (b)(1)(ii), should be specified.

(c) Internal investigation (1) In line with its just culture policy, the organisation should define how to investigate incidents such as errors or near misses, in order to understand not only what happened, but also how it happened, to prevent or reduce the probability and/or consequenc e of future recurrences (refer to AMC1 CAMO.A.202 ).

(2) The scope of internal investigations should extend beyond the scope of the occurrences required to be reported to the competent authority in accordance with point CAMO.A.160 , to include the reports referred to in CAMO.A.202(b) .

(d) Safety performance monitoring and measurement (1) Safety performance monitoring and measurement should be the process by which the safety performance of the organisation is verified in comparison with the safety policy and the safety objectives.

(2) This process may include, as appropriate to the size, nature and complexity of the organisation: (i) safety reporting, addressing also the status of compliance with the applicable requirements; (ii) safety reviews, including trends reviews, whic h would be conducted during the introduction of new products and their components, new equipment/technologies, the implementation of new or changed procedures, or in situations of organisational changes that may have an impact on safety; (iii) safety audits focusing on the integrity of the organisation’s management system, and on periodically assessing the status of safety risk controls; and (iv) safety surveys, examining particular elements or procedures in a specific area, such as problem areas identified, or bottlenecks in daily continuing airworthiness management activities, perceptions and opinions of management personnel, and areas of di ssent or confusion.

(e) Management of change The organisation should manage the safety risks related to a change. The management of change should be a documented process to identify external and internal changes that may have an adverse effect on the safety of its continuing airworthiness management activities. It should make use of the organisation’s existing hazard identification, risk assessment and mitigation processes.

(f) Continuous improvement Powered by EASA eRules Page 1113 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) SECTION A — ORGANISATION REQUIREMENTS The organisation should continuously seek to improve its safety performance and the effectiveness of its management system. Continuous improvement may be achieved through: (1) audits carried out by external organisations; (2) assessments, including assessments of the effectiveness of the safety culture and management system, in particular to assess the effectiveness of the safety risk management processes; (3) staff surveys, including cultural surveys, that can provide useful feedback on how engaged personnel are with the management system; (4) monitoring the recurrence of incidents and occurrences; (5) evaluation of safety performance indicators and review of all the available safety performance information; and (6) identification of lessons learnt.

(g) Immediate safety action and coordination with the operator’s Emergency Response Plan (ERP) (1) A procedure should be implemented to enable the organisation to act promptly when it identifies safety concerns with the potential to have immediate effect on flight safety, including clear instructions on who to contact at the owner/operator, and how to c ontact them, including outside normal business hours. These provisions are without prejudice to the occurrence reporting required by point CAMO.A.160 .

(2) If applicable, a procedure should be implemented to enable the organisation to react promptly if the ERP is triggered by the operator and it requires the support of the CAMO.

GM1 CAMO.A.200(a)(3) Management system

ED Decision 2020/002/R SAFETY RISK MANAGEMENT — INTERFACES BETWEEN ORGANISATIONS (a) Safety risk management processes should specifically address the planned implementation of, or participation of the organisation in, any complex operational and maintenance arrangements (such as when multiple organisations are contracted, or when multi ple levels of contracting/subcontracting are included).

(b) Hazard identification and risk assessment start with an identification of all the parties involved in the arrangement, including independent experts and non - approved organisations. This identification process extends to cover the overall control struct ure, and assesses in particular the following elements across all subcontract levels and all parties within such arrangements: (1) coordination and interfaces between the different parties; (2) applicable procedures; (3) communication between all the parties involved, including reporting and feedback channels; (4) task allocation, responsibilities and authorities; and (5) the qualifications and competency of key personnel with reference to point CAMO.A.305 .

(c) Safety risk management should focus on the following aspects: (1) clear assignment of accountability and allocation of responsibilities; Powered by EASA eRules Page 1114 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) SECTION A — ORGANISATION REQUIREMENTS (2) that only one party is responsible for a specific aspect of the arrangement, with no overlapping or conflicting responsibilities, in order to eliminate coordination errors; (3) the existence of clear reporting lines, both for occurrence reporting and progress reporting; (4) the possibility for staff to directly notify the organisation of any hazard that suggests an obviously unacceptable safety risk as a result of the potential consequences of this hazard.

GM2 CAMO.A.200(a)(3) Management system

ED Decision 2020/002/R MANAGEMENT OF CHANGE (a) Unless they are properly managed, changes in organisational structure, facilities, the scope of work, personnel, documentation, policies and procedures, etc. can result in the inadvertent introduction of new hazards, and expose the organisation to new or increased risk. Effective organisations seek to improve their processes, with conscious recognition that changes can expose the organisation to potentially latent hazards and risks if they are not properly and effectively managed.

(b) Regardless of the magnitude of change, large or small, its safety implications should always be proactively considered. This is primarily the responsibility of the team that proposes and/or implements the change. However, a change can only be successfu lly implemented if all the personnel affected by the change are engaged, are involved and participate in the process. The magnitude of a change, its safety criticality, and its potential impact on human performance should be assessed in any change manageme nt process.

(d) The introduction of a change is the trigger for the organisation to perform their hazard identification and risk management process.

Some examples of change include, but are not limited to: (1) changes to the organisational structure; (2) the inclusion of a new aircraft type in the terms of approval; (3) the addition of aircraft of the same or a similar type; (4) significant changes in personnel (affecting key personnel and/or large numbers of personnel, high turn - over); (5) new or amended regulations; (6) changes in the security arrangements; (7) changes in the economic situation of an organisation (e.g. commercial or financial pressure); Powered by EASA eRules Page 1115 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) SECTION A — ORGANISATION REQUIREMENTS (8) new schedule(s), location(s), equipment, and/or operational procedures; and (9) the addition of new subcontractors.

(e) A change may have the potential to introduce new, or to exacerbate pre - existing, HF issues. For example, changes in computer systems, equipment, technology, personnel changes, including changes in management personnel, procedures, work organisation, or wor k processes are likely to affect performance.

(f) The purpose of integrating HF into the management of change is to minimise potential risks by specifically considering the impact of the change on the people within a system.

(g) Special consideration, including any HF issues, should be given to the ‘transition period’. In addition, the activities utilised to manage these issues should be integrated into the change management plan.

(h) Effective management of change should be supported by the following: (1) Implementation of a process for formal hazard identification/risk assessment for major operational changes, major organisational changes, changes in key personnel, and changes that may affect the way continuing airworthiness management is carried out.

(2) Identification of changes that are likely to occur in business which would have a noticeable impact on: (i) resources — material and human; (ii) management direction — policies, processes, procedures, training; and (iii) management control.

(3) Safety cases/risk assessments that are aviation - safety focused.

(4) Involvement of key stakeholders in the change management process as appropriate.

(i) During the management of change process, previous risk assessments, and existing hazards are reviewed for possible effect.

AMC1 CAMO.A.200(a)(4) Management system

ED Decision 2020/002/R COMMUNICATION ON SAFETY (a) The organisation should establish communication about safety matters that: (1) ensures that all personnel are aware of the safety management activities, as appropriate, for their safety responsibilities; (2) conveys safety - critical information, especially related to assessed risks and analysed hazards; (3) explains why particular actions are taken; and (4) explains why safety procedures are introduced or changed.

(b) Regular meetings with personnel at which information, actions, and procedures are discussed, may be used to communicate safety matters.

ED Decision 2020/002/R SAFETY PROMOTION (a) Safety training, combined with safety communication and information sharing, forms part of safety promotion.

(b) Safety promotion activities support: (1) the organisation’s policies, encouraging a positive safety culture, creating an environment that is favourable to the achievement of the organisation’s safety objectives; (2) organisational learning; and (3) the implementation of an effective safety reporting scheme and the development of a just culture.

(c) Depending on the particular safety issue, safety promotion may also constitute or complement risk mitigation actions.

(d) Qualification and training aspects are further specified in the AMC and GM to CAMO.A.305 .

GM1 CAMO.A.200(a)(5) Management system

ED Decision 2020/002/R MANAGEMENT SYSTEM DOCUMENTATION (a) The organisation may document its safety policy, safety objectives and all its key management system processes in a separate manual (e.g. Safety Management Manual or Management System Manual) or in its CAME (cf. AMC1 CAMO.A.300 , Part 2 ‘Management system procedures’). Organisations that hold multiple organisation certificates within the scope of Regulation (EU) 2018/1139 may prefer to use a separate manual in order to avoid duplication.

That manual or the CAME, depending on the ca se, should be the key instrument for communicating the approach to the management system for the whole of the organisation.

(b) The organisation may also choose to document some of the information that is required to be documented in separate documents (e.g. policy documents, procedures). In that case, it should ensure that the manual or the CAME contains adequate references to any document that is kept separately. Any such documents are to be considered as integral parts of the organisation’s management system documentation.

AMC2 CAMO.A.200(a)(6) Management System

ED Decision 2020/002/R COMPLIANCE MONITORING — INDEPENDENT AUDIT (a) An essential element of compliance monitoring is the independent audit.

(b) The independent audit should be an objective process of routine sample checks of all aspects of the CAMO ability to carry out continuing airworthiness management to the standards required by this Regulation. It should include some product sampling as t his is the end result of the process.

(c) The independent audit should provide an objective overview of the complete set of continuing airworthiness management - related activities.

(d) The organisation should establish an audit plan to show when and how often the activities as required by Part - M, Part - ML and Part - CAMO will be audited.

(e) The audit plan should ensure that all aspects of Part - CAMO compliance are verified every year, including all the subcontracted activities, and the auditing may be carried out as a complete single exercise or subdivided over the annual period. The indep endent audit should not require each procedure to be verified against each product line when it can be shown that the particular procedure is common to more than one product line and the procedure has been verified every year without resultant findings. Wh ere findings have been identified, the particular procedure should be verified against other product lines until the findings have been closed, after which the independent audit procedure may revert to a yearly interval for the particular procedure.

(f) Provided that there are no safety - related findings, the audit planning cycle specified in this AMC may be increased by up to 100 %, subject to a risk assessment and/or mitigation actions, and agreement by the competent authority.

(g) Where the organisation has more than one location approved, the audit plan should ensure that each location is audited every year or at an interval determined through a risk assessment agreed by the competent authority and not exceeding the applicable audit planning cycle.

(h) A report should be issued each time an audit is carried out describing what was checked and the resulting non - compliance findings against applicable requirements and procedures.

AMC4 CAMO.A.200(a)(6) Management system

ED Decision 2020/002/R COMPLIANCE MONITORING — FEEDBACK SYSTEM (a) An essential element of the compliance monitoring is the feedback system.

(b) The feedback system should not be contracted to external persons or organisations.

(c) When a non - compliance is found, the compliance monitoring function should ensure that the root cause(s) and contributing factor(s) are identified (see GM1 CAMO.A.150 ), and that corrective actions are defined. The feedback part of the compliance monitoring function should define who is required to address any non - compliance in each particular case, and the procedure to be followed if the corrective action is not comple ted within the defined time frame. The principal functions of the feedback system are to ensure that all findings resulting from the independent audits of the organisation are properly investigated and corrected in a timely manner, and to enable the accoun table manager to be kept informed of any safety issues and the extent of compliance with Part - CAMO.

(d) The independent audit reports referred to in AMC2 CAMO.A.200( a)(6) should be sent to the relevant department(s) for corrective action, giving target closure dates. These target dates should be discussed with the relevant department(s) before the compliance monitoring function confirms the dates in the report. The relevan t department(s) are required to implement the corrective action and inform the compliance monitoring function of the status of the implementation of the action.

(e) Unless the review of the results from compliance monitoring is the responsibility of the safety review board (ref. AMC1 CAMO.A.200( a)(1) point (b)(4)), the accountable manager should hold regular meetings with staff to check the progress of any corrective actions. These meetings may be delegated to the compliance monitoring manager on a day - to - day basis, provided that the accountable manag er: (1) meets the senior staff involved at least twice per year to review the overall performance of the compliance monitoring function; and (2) receives at least a half - yearly summary report on non - compliance findings.

(f) All records pertaining to the independent audit and the feedback system should be retained for the period specified in point CAMO.A.220(b) or for such periods as to support changes to the audit planning cycle in accordance with AMC2 CAMO.A.200(a)(6) , whichever is the longer.

GM1 CAMO.A.200(e) Management system

ED Decision 2022/017/R INTEGRATION AND HARMONISATION OF THE MANAGEMENT SYSTEMS (a) ‘Management system’ within the scope of Regulation (EU) No 1321/2014 means a set of interrelated or interacting organisation policies, procedures, standards and processes to achieve certain objectives under an overarching safety culture.

(b) Under point CAMO.A.200(d) , an integrated management system occurs when the same organisation holds several approvals and its management system combines policies, procedures, and standards from various areas into a single structure, thus avoiding isolated procedures for common proc esses. The lines of responsibility and accountability of the organisation that holds an air operator certificate (AOC) and a CAMO approval are linked directly to the corporate authority of the operator’s accountable manager. This may be supported by a comm on manual (e.g. a common safety management manual).

(c) If organisations forming part of a single air carrier business grouping decide to facilitate the harmonisation of their management systems through standards, those standards will cover the common or consistent methods and procedures. Other elements of the management system may be covered at the discretion of the organisation, to provide flexibility and thus leverage synergy or cooperation. Harmonising management systems requires extensive and continuous exchange of information on hazard identification, safety risk management methods, strategic decisions, safety actions, compliance monitoring, and best practices.

(d) Within a single air carrier business grouping, the CAMO plays a key role in the cooperation between the operators that use that CAMO, and in the harmonisation of their management systems.

(e) Contracting a CAMO in accordance with point M.A.201(ea) implies that at least two operators will use that CAMO. As the operators’ management systems should be harmonised with the CAMO’s management system, they will also be harmonised with one another.

AMC1 CAMO.A.305(d) Personnel requirements

ED Decision 2020/002/R SUFFICIENT NUMBER OF PERSONNEL (a) The actual number of persons to be employed and their necessary qualifications is dependent upon the tasks to be performed and thus dependent on the size, nature and complexity of the organisation (general aviation aircraft, corporate aircraft, number of aircraft and the aircraft types, complexity of the aircraft and their age and for commercial air transport, route network, line or charter, ETOPS) and the amount and complexity of maintenance contracting.

Consequently, the number of persons needed, and their qualifica tions may differ greatly from one organisation to another and a simple formula covering the whole range of possibilities is not feasible.

(b) To implement a system to plan the availability of staff and to enable the competent authority to accept the number of persons and their qualifications, the organisation should make an analysis of the tasks to be performed, the way in which it intends t o divide and/or combine these tasks, indicate how it intends to assign responsibilities and establish the number of man/hours and the qualifications needed to perform the tasks. This analysis should be kept up to date and reviewed in case of significant ch anges to the organisation.

(c) In addition, as part of its management system in accordance with point CAMO.A.200 , the organisation should have a procedure to assess and mitigate risks: (1) when actual staff availability is less than the planned staffing level for any particular work shift or period; (2) in case of a temporary increase of the proportion of contracted staff for the purpose of meeting specific operational needs.

ED Decision 2022/017/R COMPETENCY ASSESSMENT OBJECTIVES The procedure referred to in point CAMO.A.305(g) should require amongst others that technical support personnel such as, planners, engineers, and technical record staff, supervisors, post - holders, airworthiness review staff, whether employed or contracted, are assessed for competency before unsupervised work commences and competency is controlled on a continuous basis.

Powered by EASA eRules Page 1137 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) SECTION A — ORGANISATION REQUIREMENTS Competency should be assessed by the evaluation of: − on - the - job performance and/or testing of knowledge by appropriately qualified personnel; − records for basic, organisational, and/or product type and differences training; and − experience records.

Validation of the above could include a confirmation check with the organisation(s) that issued such document(s). For that purpose, experience/training may be recorded in a document such as a log book.

As a result of this assessment, an individual’s qualification should determine: − which level of ongoing supervision would be required and whether unsupervised work could be permitted; − whether there is a need for additional training.

A record should be kept of each individual’s qualifications and competency assessment (refer also to point CAMO.A.220(c) ). This should include copies of all documents that attest to their qualifications, such as an authorisation held, as applicable.

For a proper competency assessment of its personnel, the organisation should consider the following: (a) In accordance with the job function, adequate initial and recurrent training should be provided and recorded to ensure continued competency so that it is maintained throughout the duration of the employment/contract.

(b) All staff should be able to demonstrate knowledge of, and compliance with, the CAMO procedures, as applicable to their duties.

(c) All staff should be able to demonstrate an understanding of safety management principles including HF, related to their job function and be trained as per AMC3 CAMO.A.305( g) .

(d) To assist in the assessment of competency and to establish the training needs analysis, job descriptions are recommended for each job function in the organisation. Job descriptions should contain sufficient criteria to enable the required competency as sessment.

(e) Criteria should allow the assessment to establish that, among other aspects (titles might be different in each organisation): (1) Managers are able to properly manage processes, resources and priorities described in their assigned duties, accountabilities and responsibilities in accordance with the safety policy and objectives and in compliance with the applicable requirements an d procedures.

(2) Maintenance programme engineers are able to interpret source data (norms, data issued by the holder of a design approval or by the competent authority, etc.) and use them to develop the aircraft maintenance programme.

(3) Engineering staff are able to interpret source data (norms, data issued by the holder of a design approval or by the competent authority, etc.) and use them as needed (e.g. to make work cards).

(4) Planners are able to organise maintenance activities in an effective and timely manner.

(5) Compliance monitoring staff are able to monitor compliance with this Regulation and to identify non - compliances in an effective and timely manner so that the organisation may remain in compliance with this Regulation.

(7) All staff are familiar with the safety policy and the procedures and tools that can be used for internal safety reporting.

(8) If the CAMO is contracted by air carriers forming part of a single air carrier business grouping (in accordance with point M.A.201(ea) ), the CAMO should ensure that all relevant personnel have sufficient skills in the agreed common language, e.g. English.

(f) The competency assessment should be based upon the procedure specified in AMC2 CAMO.A.305( g) .

AMC2 CAMO.A.305(g) Personnel requirements

ED Decision 2020/002/R COMPETENCY ASSESSMENT PROCEDURE (a) The organisation should develop a procedure that describes the process for conducting competency assessment of personnel. The procedure should specify: (1) the persons who are responsible for this process; (2) when the assessment should take place; (3) how to give credit from previous assessments; (4) how to validate qualification records; (5) the means and methods to be used for the initial assessment; (6) the means and methods to be used for the continuous control of competency, including to gather feedback on the performance of personnel; (7) the aspects of competencies to be observed during the assessment in relation to each job function; (8) the actions to be taken if the assessment is not satisfactory; and (9) how to record assessment results.

(b) Competency may be assessed by having the person work under the supervision of another qualified person for a sufficient time to arrive at a conclusion. Sufficient time could be as little as a few weeks if the person is fully exposed to relevant work. T he person need not be assessed against the complete spectrum of their intended duties. If the person has been recruited from another approved CAMO, it is reasonable to accept a written confirmation from the previous organisation.

(c) All prospective continuing airworthiness management staff should be assessed for their competency related to their intended duties.

AMC3 CAMO.A.305(g) Personnel requirements

ED Decision 2020/002/R SAFETY TRAINING (INCLUDING HUMAN FACTORS) (a) With respect to the understanding of the application of safety management principles (including HF), all organisation personnel should be assessed for the need to receive initial safety training.

Personnel involved in the delivery of the basic continuing airworthiness management services of the organisation should receive both initial and recurrent safety training, appropriate for their responsibilities.

This should include at least the following staff members: − nominated persons, line managers; − persons involved in any compliance monitoring and/or safety management related processes and tasks, including application of HF principles, internal investigations and safety training; − airworthiness review staff; − technical support personnel such as, planners, engineers, and technical record staff; − personnel involved in developing and amending/reviewing the AMP, in assessing its effectiveness and/or working on reliability programme; and − contract staff in the above categories.

The generic term ‘line managers’ refers to departmental head or person responsible for operational departments or functional units directly involved in the delivery of the basic continuing airworthiness management services of the organisation.

(b) Initial safety training should cover all the topics of the training syllabus specified in GM2 CAMO.A.305(g) either as a dedicated course or else integrated within other training. The syllabus may be adjusted to reflect the particular nature of the organisation. The syllabus may also be adjusted to suit the particular nature of work for each fu nction within the organisation.

Initial safety training compliant with the organisation’s training standards should be provided to personnel identified in accordance with point (a) of this AMC within 6 months of joining the organisation, but temporary staff may need to be trained shortly after joining the organisation to cope with the duration of employment. Personnel being recruited from another organisation, and temporary staff should be assessed for the need to receive any additional safety training.

(c) The purpose of recurrent safety training is primarily to ensure that staff remain current in terms of SMS principles and HF, and also to collect feedback on safety and HF issues. Consideration should be given to involving compliance monitoring staff an d key safety management personnel in this training to provide a consistent presence and facilitate feedback. There should be a procedure to ensure that feedback is formally reported by the trainers through the internal safety reporting scheme to initiate a ction where necessary.

Recurrent safety training should be delivered either as a dedicated course or else integrated within other training. It should be of an appropriate duration in each 2 - year period, in relation to the relevant compliance monitoring audit findings and other i nternal/external sources of information available to the organisation on safety and HF issues.

(d) Safety training may be conducted by the organisation itself, independent trainers, or any training organisations acceptable to the competent authority.

(e) To hold a position with appropriate responsibilities means the airworthiness review staff should have a position in the organisation independent from the airworthiness management process or with overall authority on the airworthiness management process of complete aircraft.

Independence from the airworthiness management process may be achieved, among other ways, as follows: − By being authorised to perform airworthiness reviews only on aircraft for which the person has not participated in their management. For example, performing airworthiness reviews on a specific aircraft type, while being involved in the continuing airworthi ness management of a different aircraft type.

− A CAMO holding a maintenance organisation approval may nominate maintenance personnel from their maintenance organisation as airworthiness review staff, as long as they are not involved in the airworthiness management of the aircraft. These personnel shoul d not have been involved in the release to service of that particular aircraft (other than maintenance tasks performed during the physical survey of the aircraft or performed as a result of findings discovered during such physical survey) to avoid possible conflict of interests.

− By nominating as airworthiness review staff personnel from the compliance monitoring department of the CAMO.

Overall authority on the airworthiness management process of complete aircraft may be achieved, among other ways, as follows: − By nominating as airworthiness review staff the accountable manager or the nominated post holder.

− By being authorised to perform airworthiness reviews only on those particular aircraft for which the person is responsible for the complete continuing airworthiness management process.

− In the case of one - man organisations, this person has always overall authority. This means that this person can be nominated as airworthiness review staff.

Thus, it should be satisfied before the intended flight that all required maintenance has been properly carried out.

(c) The CAMO should agree with the operator on the process to select a maintenance organisation before concluding any contract with a maintenance organisation.

(d) The fact that the CAMO has contracted a maintenance organisation should not prevent it from checking at the maintenance facilities on any aspect of the contracted work to fulfil its responsibility for the airworthiness of the aircraft.

(e) The contract between the CAMO and the maintenance organisation(s) should specify in detail the responsibilities and the work to be performed by each party.

(f) Both the specification of work and the assignment of responsibilities should be clear, unambiguous and sufficiently detailed to ensure that no misunderstanding arises between the parties concerned that could result in a situation where work that has an effect on the airworthiness or serviceability of aircraft is not or will not be properly performed.

(g) Special attention should be paid to procedures and responsibilities to ensure that all maintenance work is performed, service bulletins are analysed, and decisions are taken on their accomplishment, airworthiness directives are accomplished on time and tha t all work, including non - mandatory modifications, is carried out to approved or declared (in accordance with Part 21 Light Subpart C) data and to the latest standards .

(h) Appendix IV to AMC1 CAMO.A.315(c) gives further details on the subject.

AMC2 CAMO.A.315(c) Continuing airworthiness management

ED Decision 2020/002/R MAINTENANCE CONTRACT WITH ANOTHER CAMO/OPERATOR (a) The purpose of point CAMO.A.315(c) is to ensure that all maintenance is carried out by an appropriately approved maintenance organisation. It is acceptable to contract another operator/CAMO (secondary operator/CAMO) that does not hold a maintenance organisation approval when it proves that such a contract is in the interest of the CAMO by simplifying the management of its maintenance, and the CAMO keeps an appropriate control of it. In this case, the CAME should include appropriate procedures to ensure that all maintenance is ultimately car ried out on time by approved maintenance organisations in accordance with appropriate maintenance data. In particular, the compliance monitoring and safety risk management procedures should place great emphasis on monitoring compliance with the above and e nsuring proper hazard identification, and management of risks associated with such contracting. The list of approved maintenance organisations, or a reference to this list, should be included in the CAME.

(b) This contract should not preclude the CAMO from ensuring that all maintenance is performed by appropriately approved organisations which comply with M.A.201 or ML.A.201 . Typical arrangements are the following: − Component maintenance: The CAMO may find it more appropriate to have a primary contractor (the secondary operator/CAMO) dispatching the components to appropriately approved organisations rather than sending themselves different types of components to various maintenance organisa tions approved under Part - 145. The benefit for the CAMO is that the management of maintenance is simplified by having a single point of contact for Powered by EASA eRules Page 1150 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) SECTION A — ORGANISATION REQUIREMENTS component maintenance. The CAMO remains responsible for ensuring that all maintenance is performed by maintenance organisations approved under Part - 145 and in accordance with appropriate maintenance data.

− Aircraft, engine and component maintenance: The CAMO may wish to have a maintenance contract with a secondary operator/CAMO not approved as maintenance organisation for the same type of aircraft. A typical case is that of a dry - leased aircraft between operators where the parties, for consistency or continuity reasons (especially for short - term lease agreements), find it appropriate to keep the aircraft under the current maintenance arrangement. Where this arrangement involves various maintenance organisations, it might be more manageable for the less ee CAMO to have a single maintenance contract with the lessor operator/CAMO. Whatever type of acceptable maintenance contract is concluded, the CAMO is required to exercise the same level of control on contracted maintenance, particularly through the perso n(s) nominated under point CAMO.A.305(a) and the management system as referred to in CAMO.A.200 .

GM1 CAMO.A.315(c) Continuing airworthiness management

ED Decision 2020/002/R LINE MAINTENANCE CONTRACT For line maintenance, the actual layout of the IATA Standard Ground Handling Agreement may be used as a basis, but this does not preclude the CAMO from ensuring that the content of the contract is acceptable and especially that the contract allows the CAMO to properly exercise its continuing airworthiness management responsibility. Those parts of the co ntract that have no effect on the technical or operational aspects of airworthiness are outside the scope of this paragraph.

GM1 CAMO.A.315(d) Continuing airworthiness management

ED Decision 2020/002/R WORK ORDERS The intent of this paragraph is that maintenance contracts are not necessary when the continuing airworthiness management exposition specifies that the relevant maintenance activity may be ordered through one - time work orders. This includes unscheduled lin e maintenance and may also include component maintenance up to engines, as long as the maintenance is manageable through work orders, in terms of both volume and complexity. It should be noted that this paragraph implies that even where base maintenance is ordered on a case - by - case basis, there should be a written maintenance contract.

GM1 CAMO.B.200(a)(5) Management system

ED Decision 2020/002/R SAFETY RISK MANAGEMENT PROCESS The purpose of safety risk management as part of the management system framework for competent authorities is to ensure the effectiveness of the management system. As for any organisation, hazard identification and risk management is expected to contribute to effective decision - making, to guide the allocation of resources and contribute to organisational success.

The safety risk management process required by point CAMO.B.200 is intended to address the safety risks that are directly related to the competent authority’s organisation and processes, and which may affect its capability to perform its tasks and discharge its responsibilities. This process is not intended to be a su bstitute for the State safety risk management SARPs defined in ICAO Annex 19, Chapter 3, component 3.3. This does not mean, however, that the competent authority may not use information Powered by EASA eRules Page 1165 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) SECTION B — AUTHORITY REQUIREMENTS and data that is obtained through its State Safety Programme (SSP), including oversight data and information, for the purpose of safety risk management as part of its management system.

The safety risk management process is also to be applied to the management of changes ( CAMO.B.210 ), which is intended to ensure that the management system remains effective whenever changes occur.

ED Decision 2020/002/R PROCEDURES TO BE MADE AVAILABLE TO THE AGENCY (a) Copies of the procedures related to the competent authority’s management system, and their amendments, that should be made available to the Agency for the purpose of standardisation, should provide at least the following information: (1) the competent authority’s organisational structure for the continuing oversight functions that it undertakes, with a description of the main processes. This information should demonstrate the allocation of responsibilities within the competent authorit y, and that the competent authority is capable of carrying out the full range of tasks for the size and complexity of the Member State’s aviation industry. It should also consider the overall proficiency and the scope of authorisation of the competent auth ority’s personnel; (2) for personnel who are involved in oversight activities, the minimum required professional qualification and amount of experience, and the principles that are used to guide their appointment (e.g. assessment); (3) how the following are carried out: assessments of applications and evaluations of compliance, the issuing of certificates, continuing oversight activities, the follow - up of findings, enforcement measures and the resolution of safety concerns; (4) the principles used for the management of exemptions and derogations; (5) the processes that are in place to distribute the applicable safety information to enable a timely reaction to a safety problem; (6) the criteria for planning continuing oversight activities (i.e. oversight programme), including the management of interfaces when conducting continuing oversight activities (of air operations and of continuing airworthiness management, for example); and (7) an outline of the initial training of newly recruited oversight personnel (taking future activities into account), and the basic framework for the recurrent training of oversight personnel.

(b) As part of the continuous monitoring of a competent authority, the Agency may request details of the working methods used, in addition to a copy of the procedures of the competent authority’s management system (and any amendments). These additional det ails are the procedures and the related guidance material that describe the working methods for the personnel of the competent authority who conduct oversight activities.

GM 2 CAMO.B.300(g) Oversight principles

ED Decision 2022/017/R ASSESSMENT OF HARMONISED MANAGEMENT SYSTEMS (a) One of the core capabilities that are required for supporting the effective implementation of safety management is the ability to monitor the effectiveness of an organisation’s management system. Competent authorities assess that effectiveness as part of t heir oversight activities.

Cooperation between several competent authorities on that assessment is necessary, especially when different organisations have harmonised management systems as required by point M.A.201(ea) .

(b) To ensure cooperative oversight and sound decision - making regarding oversight across a single air carrier business grouping, the competent authorities involved are expected to provide for the following: (1) Use a common approach to the assessment of the management system, including the continuous improvement of the management systems across the operator(s) and the CAMO involved. Different competent authorities may not necessarily use the same tool to asse ss the maturity of the harmonised management systems. However, they will coordinate on this matter and share with one another to which extent their assessment approach follows the principles that are set out in GM1 CAMO.B.300(a);(b);(c) . This way, all competent authorities involved will have an overall understanding of how each competent authority evaluates compliance and effectiveness of the management system(s).

(2) When a finding is raised on a harmonised procedure or, if used, on a group standard, the other competent authority(ies) is/are informed, and the related root cause analysis and corrective action plan that are developed by the operator(s) and CAMO conce rned are shared with all competent authorities involved. In addition, the informed competent authority(ies) will assess if such a finding is relevant for the organisation under its/their oversight and, depending on the conclusion of such an assessment, wil l take appropriate action (e.g. take no action, communicate with the organisation or with the competent authority that raised the finding, or raise a finding itself/themselves).

(c) Regarding the duration of the oversight planning cycle of the organisations whose management systems are harmonised: (1) even if the management systems of organisations are harmonised with each other, the maturity levels of those management systems may differ; as the oversight planning cycle is mainly driven by the management system’s maturity and the organisation’s comp liance Powered by EASA eRules Page 1174 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) SECTION B — AUTHORITY REQUIREMENTS records, some organisations may have an oversight planning cycle of 24 months (or less) and others a 36 - or 48 - month cycle; (2) the competent authorities involved will inform each other when the duration of the oversight planning cycle of the organisation(s) under their oversight is to be increased or reduced.

CAM O.B.305 Oversight programme

Regulation (EU) 2019/1383 (a) The competent authority shall establish and maintain an oversight programme covering the oversight activities required by point CAMO.B.300 .

(b) The oversight programme shall be developed taking into account the specific nature of the organisation, the complexity of its activities, the results of past certification and/or oversight activities, and shall be based on the assessment of associated risks. It shall include within each oversight planning cycle: (1) assessments, audits and inspections, including unannounced inspections and, as applicable: (i) management system assessments and process audits; (ii) product audits of a relevant sample of aircraft managed by the organisation; (iii) sampling of airworthiness reviews performed; (iv) sampling of permits to fly issued; (2) meetings convened between the accountable manager and th e competent authority to ensure both remain informed of significant issues.

(c) For organisations certified by the competent authority, an oversight planning cycle not exceed ing 24 months shall be applied.

(d) Notwithstanding point (c), the oversight planning cycle may be extended up to 36 months if the competent authority has established that during the previous 24 months: (1) the organisation has demonstrated an effective identification of aviation safety hazards and management of associated risks; (2) the organisation has continuously demonstrated under point CAMO.A.130 that it has full control over all changes; (3) no level 1 findings have been issued; (4) all corrective actions have been implemented within the time period accepted or extended by the competent authority as defined in point CAMO.B.350 .

Notwithstanding point (c), the oversight planning cycle may be furt her extended to a maximum of 48 months if, in addition to the conditions provided in points (1) to (4) of the first subparagraph, the organisation has established, and the competent authority has approved, an effective continuous reporting system to the competent authority on the safety performance and regulatory compliance of the organisation itself.

(e) The oversight planning cycle may be reduced if there is any evidence that the safety performance of the organisation has decreased.

ED Decision 2020/002/R OVERSIGHT PLANNING CYCLE — AUDIT AND INSPECTION (a) When determining the oversight planning cycle and defining the oversight programme, the competent authority should assess the risks related to the activity of each organisation, and adapt the oversight to the level of risk identified and to the effectivene ss of the organisation’s management system, in particular its ability to effectively manage safety risks.

(c) When the competent authority, having regard to the level of risk identified and the effectiveness of the organisation’s management system, varies the frequency of an audit or inspection, it should ensure that all aspects of the organisation’s activity are audited and inspected within the applicable oversight planning cycle.

AMC2 CAMO.B.305(c) Oversight programme

ED Decision 2020/002/R OVERSIGHT PLANNING CYCLE — AUDIT (a) For each organisation certified by the competent authority, all processes should be completely audited at periods that do not exceed the applicable oversight planning cycle. The beginning of the first oversight planning cycle is normally determined by the date of issue of the first certificate. If the competent authority wishes to align the oversight planning cycle with the calendar year, it should shorten the first oversight planning cycle accordingly.

(b) The interval between two audits for a particular process should not exceed the interval of the applicable oversight planning cycle.

(d) For organisations holding more than one certificate, the competent authority may define an integrated oversight schedule to include all the applicable audit items. In order to avoid any duplication of audits, credit may be granted for specific audit it ems that have already been completed during the current oversight planning cycle, provided that: (1) the specific audit item is the same for all the certificates under consideration; (2) there is satisfactory evidence on record that those specific audit items were carried out, and that all the related corrective actions have been implemented to the satisfaction of the competent authority; (3) the competent authority is satisfied that there is no evidence that standards have deteriorated regarding those specific audit items for which credit is granted; (4) the interval between two audits for the specific item for which credit is granted does not exceed the applicable oversight planning cycle.

AMC1 CAMO.B.305(d) Oversight programme

ED Decision 2020/002/R EXTENSION OF THE OVERSIGHT PLANNING CYCLE BEYOND 24 MONTHS (a) If the competent authority applies an oversight planning cycle that exceeds 24 months, it should, at a minimum, perform one focused inspection of the organisation (inspection of a specific area, element or aspect of the organisation) within each 12 - mon th segment of the cycle to support the extended oversight programme.

NOTE: Where another inspection can be linked to the oversight of the organisation (e.g. when an aircraft managed by the organisation is inspected through ACAM survey), then the competent authority may take credit of such inspection to maintain the extension beyond 24 months.

(b) If the results of this inspection indicate a decrease in the safety performance or regulatory compliance of the organisation, the competent authority should revert to a 24 - month (or less) oversight planning cycle and review the oversight programme acco rdingly.

(c) In order to be able to approve an oversight planning cycle of beyond 36 months, the competent authority should agree on the format and contents of the continuous reporting to be made by the organisation on its safety performance and regulatory complian ce.

AMC 1 CAMO.B.310(a) Initial certification procedure

ED Decision 2020/002/R AUDIT (a) The competent authority should determine how and by whom the audit shall be conducted. For example, it will be necessary to determine whether one large team audit, a short series of small team audits, or a long series of single inspector audits is most app ropriate for the particular situation.

(b) The audit may be structured so as to verify the organisation’s processes related to a product line. For example, in the case of an organisation with Airbus A320 and Airbus A310 ratings, the audit should concentrate on the continuing airworthiness manag ement processes of one type only for a full compliance check, and depending upon the result, the second type may only require a sample check against those aspects that were seen to be weak regarding compliance for the first type.

(c) In determining the scope of the audit and which activities of the organisation will be assessed during the audit, the privileges of the approved organisation should be taken into account, e.g.

their approval to carry out airworthiness reviews.

(d) The competent authority auditing inspector should always ensure that he or she is accompanied throughout the audit by a senior member of the organisation, who is normally the compliance monitoring manager. The reason for being accompanied is to ensure that the organisation is fully aware of any findings raised during the audit.

(e) At the end of the audit, the auditing inspector should inform the senior member of the organisation of all the findings that were raised during the audit.

AMC1 CAMO.B.310(c) Initial certification procedure

ED Decision 2020/002/R (a) There may be occasions when the competent authority inspector is unsure about the compliance of some aspects of the applicant's organisation. If this occurs, the inspector should inform the organisation about the possible non - compliance at the time, an d about the fact that the situation will be reviewed within the competent authority before a decision is made. If the review concludes that there is no finding, then a verbal confirmation to the organisation should suffice.

GM1 CAMO.B.310(e)(1); CAMO.B.330 Initial certification procedure

and changes

ED Decision 2020/002/R TERMS OF APPROVAL The table shown for the terms of approval in EASA Form 14 includes a field designated as ‘Aircraft type/series/group’.

The intention is to give maximum flexibility to the competent authority to customise the approval to a particular organisation.

Possible alternatives to be included in this field are the following: − A specific type designation that is part of a type certificate, such as Airbus 340 - 211 or Cessna 172R.

− A type rating (or series) as listed in Part - 66 Appendix I to AMC, which may be further subdivided, such as Boeing 737 - 600/700/800, Boeing 737 - 600, Cessna 172 Series.

− An aircraft group such as, for example, ‘all sailplanes and powered sailplanes’ or ‘Cessna single piston engine aircraft’ or ‘Group 3 aircraft’ (as defined in 66.A.5 ) or ‘aircraft below 2 730 kg MTOM’.

Reference to the engine type installed in the aircraft may or may not be included, as necessary.

It is important to note that the terms of approval defined in EASA Form 14 is further limited to the scope of work defined in the CAME. It is this scope of work in the CAME which ultimately defines the approval of the organisation. As a consequence, it is possible for a competent authority to endorse in Powered by EASA eRules Page 1181 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) SECTION B — AUTHORITY REQUIREMENTS EASA Form 14 , for example, a scope of work for Group 3 aircraft while the detailed scope of work defined in the CAME does not include all Group 3 aircraft.

Nevertheless, in all cases, the competent authority should be satisfied that the organisation has the capability of managing the types/groups/series endorsed in EASA Form 14 .

Since the activities linked to continuing airworthiness management are mainly process - oriented rather than facility/tooling - oriented, changes to the detailed scope of work defined in the CAME (either directly or through a capability list), within the limit s already included in EASA Form 14 , may be considered as not affecting the approval and not subject to point CAMO.A.130 (a). As a consequence, for these changes, the competent authority may allow the use by the CAMO of the procedure referred to in point CAMO.A.130 (c) for changes not requiring prior approval.

AMC1 CAMO.B.310(e)(2) Initial certification procedure

ED Decision 2020/002/R (a) The competent authority should indicate its approval of the CAME in writing.

(b) Contracts for subcontracting continuing airworthiness management tasks by CAMOs should be included in the continuing airworthiness organisation exposition. The competent authorities should verify that the standards set forth in AMC1 CAMO.A.125(d)(3) have been met when approving the exposition.

(c) The competent authority while investigating the acceptability of the proposed subcontracted continuing airworthiness management tasks arrangements should take into account, in the subcontracted organisation, all other such contracts that are in place i rrespective of state of registry in terms of sufficiency of resources, expertise, management structure, facilities and Powered by EASA eRules Page 1182 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) SECTION B — AUTHORITY REQUIREMENTS liaison between the CAMO, the subcontracted organisation and, where applicable, the contracted maintenance organisation(s).

(e) The competent authority may reject an accountable manager if there is clear evidence that this person previously held a senior position in any organisation that was approved in accordance with Regulation (EU) 2018/1139 and its delegated and implementin g acts, and that the person abused that position by not complying with the applicable requirements.

(e) For CAT, commercial specialised operations and commercial ATO or commercial DTO operations, the initial approval of the aircraft technical log system required by M.A.306(b) and M.B.305 may be done by approving the CAME in which this system should be described.

CAMO.B.330 Changes

Regulation (EU) 2019/1383 (a) Upon receiving an application for a change that requires prior approval, the competent authority shall verify the organisation’s compliance with the applicable requirements before issuing the approval.

(b) The competent authority shall establish the conditions under which the organisation may operate during the change unless the competent authority determines that the organisation’s certificate needs to be suspended.

(c) When satisfied that the organisation complies with the applicable requirements, the competent authority shall approve the change.

(d) Without prejudice to any additional enforcement measures, when the organisation implements changes requiring prior approval without having received competent authority approval pursuant to point (c), the competent authority shall suspend, limit or revo ke the organisation’s certificate.

(e) For changes not requiring prior approval, the competent authority shall assess the information provided in the notification sent by the organisation in accordance with point (c) of point CAMO.A.130 to verify compliance with the applicable requirements. In case of any non - compliance, the competent authority shall: (1) notify the organisation about the non - compliance and request further changes; (2) in case of level 1 or level 2 findings, act in accordance with point CAMO.B.350 .

AMC1 CAMO.B.330 Changes

ED Decision 2020/002/R (a) The competent authority should have adequate control over any changes to the personnel specified in points CAMO.A.305(a) , (b)(2), (e) and (f). Such changes in personnel will require an amendment to the exposition.

(b) When an organisation submits the name of a new nominee for any of the personnel specified in points CAMO.A.305(a) , (b)(2) and (e), the competent authority may require the organisation to produce a written résumé of the proposed person's qualifications. The competent authority should reserve the right to interview the nominee or call for additional evidence of his or her suitability before deciding upon him or her being acceptable.

Appendix II to AMC1 CAMO.A.125(d)(3) — Subcontracting of

continuing airworthiness management tasks

ED Decision 2023/013/R 1. Subcontracted continuing airworthiness management tasks 1.1. To actively control the standards of the subcontracted organisation, the CAMO should employ a person or group of persons who are trained and competent in the disciplines associated with Part - CAMO. As such, they are responsible for determining what mai ntenance is required, when it has to be performed, by whom and to what standard in order to ensure the continuing airworthiness of the aircraft to be operated.

1.2. The CAMO should conduct a pre - subcontract audit to establish that the organisation to be subcontracted can achieve the standards required by Part - CAMO in connection with the activities to be subcontracted.

1.3. The CAMO should ensure that the organisation to be subcontracted has sufficient and qualified personnel who are trained and competent in the functions to be subcontracted. In assessing the adequacy of personnel resources, the CAMO should consider the particular needs of those activities that are to be subcontracted, while taking into account the subcontracted organisations existing commitments.

1.4. To be appropriately approved to subcontract continuing airworthiness management tasks, the CAMO should have procedures for the management control of these arrangements. The CAME should contain relevant procedures to reflect its control of those arrang ements made with the subcontracted organisation.

1.5. Subcontracted continuing airworthiness management tasks should be addressed in a contract between the CAMO and the subcontracted organisation. The contract should also specify that the subcontracted organisation is responsible for informing the CAMO t hat is in turn responsible for notifying the respective competent authority, of any subsequent changes that affect their ability to fulfil the contract.

1.7. Where the subcontracted organisation develops its own procedures, they should be compatible with the CAME and the terms of the contract. These should be accepted by the competent authority as extended procedures of the CAMO and as such should be cross - referenced in the CAME. One current copy of the subcontracted organisation’s relevant procedures should be kept by the CAMO and should be accessible to the competent authority when needed.

Note: Should any conflict arise between the subcontracted organisation’s procedures and those of the CAMO, then the policy and procedures of the CAME will prevail.

Powered by EASA eRules Page 1191 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM to ANNEX Vc (Part - CAMO) 1.9. Whenever any elements of the continuing airworthiness management tasks are subcontracted, the CAMO personnel should have access to all relevant data in order to fulfil their responsibilities.

Note: The CAMO retains the authority to override, whenever necessary for the continuing airworthiness of their aircraft, any recommendation of the subcontracted organisation.

1.10. The CAMO should ensure that the subcontracted organisation continues to have qualified technical expertise and sufficient resources to perform the subcontracted tasks while complying with the relevant procedures. Failure to do so may invalidate the CAMO approval.

1.11. The contract should provide for competent authority monitoring.

2. Accomplishment This paragraph describes the topics which may be applicable to such subcontracting arrangements.

2.1. Scope of work The type of aircraft and their registrations, engine types and/or components subject to the continuing airworthiness management tasks contract should be specified.

2.2. Maintenance programme development and amendment The CAMO may subcontract the preparation of the draft maintenance programme and any subsequent amendments. However, the CAMO remains responsible for assessing that the draft proposals meet its needs and for obtaining competent authority approval, where app licable; the relevant procedures should specify these responsibilities. The contract should also stipulate that any data necessary to substantiate the approval of the initial programme or an amendment to this programme should be provided for CAMO agreement and/or competent authority upon request.

2.3. Maintenance programme effectiveness and reliability The CAMO should have a system in place to monitor and assess the effectiveness of the maintenance programme based on maintenance and operational experience. The collection of data and initial assessment may be made by the subcontracted organisation; the re quired actions are to be endorsed by the CAMO.

2.4. Permitted variations to the maintenance programme The reasons and justification for any proposed variation to scheduled maintenance may be prepared by the subcontracted organisation. Acceptance of the proposed variation should be Powered by EASA eRules Page 1192 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM to ANNEX Vc (Part - CAMO) granted by the CAMO. The means by which the CAMO acceptance is given should be specified in the relevant procedures. When outside the limits set out in the maintenance programme, the CAMO is required to obtain approval by the competent authority.

The planning control and documentation should be specified in the appropriate supporting procedures. These procedures should typically set out the CAMO’s level of involvement in each type of check. This will normally involve the CAMO assessing and agreeing to a work specification on a case - by - case basis for base maintenance checks. For routine line maintenance checks, this may be controlled on a day - to - day basis by the subcontracted organisation subject to appropriate liaison and CAMO controls to ensure tim ely compliance. This may typically include but is not necessarily limited to: − applicable work package, including work cards; − scheduled component removal list; − ADs to be incorporated; − modifications to be incorporated.

The associated procedures should ensure that the CAMO is informed in a timely manner of the accomplishment of such tasks.

2.6. Compliance monitoring and risk assessment The CAMO’s management system should monitor the adequacy of the subcontracted continuing airworthiness management task performance for compliance with the contract and with Part - CAMO and assess the risks entailed by such subcontracting. The terms of the co ntract should therefore include a provision allowing the CAMO to perform a surveillance (including audits and assessments) of the subcontracted organisation. The aim of the surveillance is primarily to investigate and judge the effectiveness of those subco ntracted activities and thereby to ensure compliance with Part - CAMO and the contract and mitigate related safety risks. Audit and assessment reports may be subject to review when requested by the competent authority.

2.7. Access to the competent authority The contract should specify that the subcontracted organisation should always grant access to the competent authority.

2.8. Maintenance data The maintenance data used for the purpose of the contract should be specified, together with those responsible for providing such documentation and the competent authority responsible for the acceptance/approval of such data, when applicable. The CAMO shou ld ensure that such data, including revisions, is readily available to the CAMO personnel and to those in the subcontracted organisation who may be required to assess such data. The CAMO should establish a ‘fast - track’ means to ensure that urgent data is t ransmitted to the subcontractor in a timely manner. Maintenance data is defined in M.A.401(b) or ML.A.401(b) .

2.9. Airworthiness directives (ADs) Powered by EASA eRules Page 1193 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM to ANNEX Vc (Part - CAMO) While the various aspects of AD assessment, planning and follow - up may be accomplished by the subcontracted organisation, AD embodiment is performed by a maintenance organisation.

The CAMO is responsible for ensuring timely embodiment of the applicable ADs and is to be provided with notification of compliance. It, therefore, follows that the CAMO s hould have clear policies and procedures on AD embodiment supported by defined procedures which will ensure that the CAMO agrees to the proposed means of compliance.

To fulfil the above responsibility, the CAMO should ensure that it receives current mandatory continued airworthiness information for the aircraft and equipment it is managing.

2.10. Service bulletin (SB) modifications The subcontracted organisation may be required to review and make recommendations on the embodiment of an SB and other associated non - mandatory material based on a clear policy established by the CAMO. This should be specified in the contract.

2.11. Mandatory life limitation or scheduled maintenance controls and component control/removal forecast Where the subcontracted organisation performs planning activities, it should be specified that the organisation should receive the current flight cycles, flight hours, landings and/or calendar controlled details, as applicable, at a frequency to be specifi ed in the contract. The frequency should be such that it allows the organisation to properly perform the subcontracted planning functions. It, therefore, follows that there will need to be adequate liaison between the CAMO, the contracted maintenance organ isation(s) and the subcontracted organisation. Additionally, the contract should specify how the CAMO will be in possession of all current flight cycles, flight hours, etc., so that it may assure the timely accomplishment of the required maintenance.

2.13. Defect control Where the CAMO has subcontracted the day - to - day control of technical log deferred defects, this should be specified in the contract and should be adequately described in the appropriate procedures. The operator’s minimum equipment list (MEL)/configuration deviation list (CDL) provides the basis for establishing which defects may be deferred and the associated limits. The procedures should also define the responsibilities and actions to be tak en for defects such as aircraft on ground (AOG) situations, repeti tive defects, and damage beyond the limits established by the type certificate holder or the declarant of a declaration of design compliance .

For all other defects identified during maintenance, the information should be brought to the attention of the CAMO which, depending upon the procedural authority granted by the Powered by EASA eRules Page 1194 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM to ANNEX Vc (Part - CAMO) competent authority, may determine that some defects can be deferred. Therefore, adequate liaison between the CAMO, its subcontracted organisation and contracted maintenance organisation should be ensured.

2.14. Occurrence reporting All incidents and safety occurrences should be collected, and those that meet the reporting criteria should be reported as required by point CAMO.A.160 in accordance with a procedure established by the CAMO (see GM1 CAMO.A.205 ).

The record - keeping requirements of point CAMO.A.220 should be met. Access to the records by duly authorised members of the competent authority should be granted upon request.

2.17.2. Meetings provide one important cornerstone whereby the CAMO can fulfil part of its responsibility for ensuring the airworthiness of the operated aircraft. They should be used to establish good communication between the CAMO, the subcontracted organ isation and the contracted maintenance organisation. The terms of the contract should include, whenever appropriate, the provision for a certain number of meetings to be held between the involved parties. Details of the types of liaison meetings and associ ated terms of reference of each meeting should be documented. The meetings may include but are not limited to all or a combination of: (a) Contract review Before the contract is enforced, it is very important that the technical personnel of both parties, that are involved in the fulfilment of the contract, meet in order to be sure that every point leads to a common understanding of the duties of both parties .

Appendix IV to AMC1 CAMO.A.315(c) — Contracted maintenance

ED Decision 2023/013/R 1. Maintenance contracts The following paragraphs are not intended to provide a standard maintenance contract, but to provide a list of the main points that should be addressed, when applicable, in a maintenance contract between the CAMO and the maintenance organisation. The follo wing paragraphs only address technical matters and exclude matters such as costs, delay, warranty, etc.

A maintenance contract is not normally intended to provide appropriate detailed work instructions to personnel. Accordingly, there should be established organisational roles and responsibilities, procedures and routines in the CAMO and the maintenance orga nisation to cover these functions in a satisfactory way such that any person involved is informed about his/her accountabilities, responsibilities and the procedures that apply. These procedures and routines can be included/appended to the CAME and to the maintenance organisation’s manual/maintenance organisation exposition (MOE), or can consist in separate procedures. In other words, procedures and routines should reflect the conditions of the contract.

2. Aircraft/engine maintenance The following subparagraphs may be adapted to a maintenance contract that applies to aircraft base maintenance, aircraft line maintenance, and engine maintenance.

Aircraft maintenance also includes the maintenance of the engines and auxiliary power units (APU) while they are installed on the aircraft.

In case of engine maintenance, the contract should specify the engine type.

Access should be given to the CAMO to any information (especi ally the compliance monitoring information) about the maintenance organisation’s subcontractors involved in the contract. It should, however, be noted that under the CAMO responsibility both the CAMO and its Powered by EASA eRules Page 1198 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM to ANNEX Vc (Part - CAMO) competent authority are entitled to be fully informed about subcontracting, although the competent authority will normally only be concerned with aircraft, engine and APU subcontracting.

2.4. Maintenance programme The maintenance programme, under which maintenance has to be performed, has to be specified.

The CAMO should have that maintenance programme approved by its competent authority.

2.5. Monitoring The terms of the contract should include a provision allowing the organisation to monitor the maintenance organisation in terms of compliance with the applicable requirements. The maintenance contract should specify how the results of such monitoring are t aken into account by the maintenance organisation (See also paragraph 2.23. ‘Meetings’).

This may include but is not limited to: − maintenance programme, − airworthiness directives, − repairs/modification data, − aircraft maintenance manual, − aircraft illustrated parts catalogue (IPC), − wiring diagrams, − troubleshooting manual, − MEL (normally on board the aircraft), − operator’s manual, − flight manual, − engine maintenance manual, − engine overhaul manual.

2.8. Incoming conditions The contract should specify in which condition the aircraft should be made available to the maintenance organisation. For extensive maintenance, it may be beneficial that a work scope planning meeting be organised so that the tasks to be performed may be c ommonly agreed (see also paragraph 2.23 ‘Meetings’).

Powered by EASA eRules Page 1199 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM to ANNEX Vc (Part - CAMO) 2.9. Airworthiness directives and service bulletins/modifications The contract should specify the information that the CAMO is responsible to provide to the maintenance organisation, such as: − the status of the ADs including due date and the selected means of compliance, if applicable; and − status of modifications and the decision to embody a modification or an SB.

In addition, the contract should specify the type of information the CAMO will need in return to complete the control of ADs and modification status.

2.11. Life - limited parts and time - controlled components The control of life - limited parts and time - controlled components is the responsibility of the CAMO. The contract should specify whether the CAMO should provide the status of life - limited parts and time - controlled components to the maintenance organisation, and the information that the approved organisation will have to provide to the CAMO about the removal/installation of the life - limited parts and time - controlled components so that the CAMO may update its records (see also paragraph 2.22 ‘Exchange of infor mation’).

2.12. Supply of parts The contract should specify whether a particular type of material or component is supplied by the CAMO or by the maintenance organisation, which type of component is pooled, etc. The contract should clearly state that it is the maintenance organisation’s r esponsibility to be satisfied that the component in question meets the approved or declared (in accordance with Part 21 Light Subpart C) data/standard and to ensure that the aircraft component is in a satisfactory condition for installation. Additional gui dance on the acceptance of components is provided in M.A.501 , ML.A.501 and 145.A.42 .

2.13. Pooled parts at line stations If applicable, the contract should specify how the subject of pooled parts at line stations should be addressed.

2.14. Scheduled maintenance For planning scheduled maintenance checks, the support documentation to be given to the maintenance organisation should be specified. This may include but is not limited to: − applicable work package, including work cards; − scheduled component removal list; − modifications to be incorporated.

When the maintenance organisation decides, for any reason, to defer a maintenance task, it has to be formally agreed with the CAMO. If the deferment goes beyond an approved limit, please refer to paragraph 2.17 ‘Deviation from the maintenance schedule’. Th is should be addressed, where applicable, in the maintenance contract.

Powered by EASA eRules Page 1200 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vc (Part - CAMO) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM to ANNEX Vc (Part - CAMO) 2.15. Unscheduled maintenance/defect rectification The contract should specify to which level the maintenance organisation may rectify a defect without reference to the CAMO. It should describe, as a minimum, the management of approval of repairs and the incorporation of repairs. The deferment of any defec t rectification should be submitted to the CAMO.

2.16. Deferred tasks See paragraphs 2.14 and 2.15 above, as well as 145.A.50(e) , M.A.801(f) and ML.A.801(f) . In addition, for aircraft line and base maintenance, the use of the operator’s MEL and the liaison with the CAMO in case of a defect that cannot be rectified at the line station should be addressed.

2.17. Deviation from the maintenance schedule Deviations from the maintenance schedule have to be managed by the CAMO in accordance with the procedures established in the maintenance programme. The contract should specify the support the maintenance organisation may provide to the operator in order to substantiate the deviation request.

2.18. Maintenance check flight (MCF) If any MCF is required after aircraft maintenance, it should be performed in accordance with the procedures established in the CAME and/or the operator’s manual.

2.19. Bench test The contract should specify the acceptability criterion and whether a representative of the CAMO should witness an engine undergoing test.

2.21. Maintenance record - keeping The CAMO may subcontract the maintenance organisation to retain some of the maintenance records required by Part - M Subpart C. This means that the CAMO subcontracts under its management system part of its record - keeping tasks and, therefore, the provisions of point CAMO.A.125(d)(3) apply.

Exchange of information Each time exchange of information between the CAMO and the maintenance organisation is necessary, the contract should specify what information should be provided and when (i.e. in which case or at what frequency), how, by whom and to whom it has to be tran smitted.

2.23. Meetings The maintenance contract should include the provision for a certain number of meetings to be held between the CAMO and the maintenance organisation.

2.23.2. Work scope planning meeting Work scope planning meetings may be organised so that the tasks to be performed may be commonly agreed.

2.23.4. Compliance and performance meeting Compliance and performance meetings may be organised in order to examine matters raised by the CAMO’s monitoring and to agree upon necessary preventive and corrective actions.

If the scope of work contains the Rotax 912 A Series complete piston engine, the combined airworthiness organisation (CAO) shall control changes to the scope of work for additional complete piston engines (e.g. Rotax 914 series or LOM M 332 Series) in acco rdance with CAO.A.105(b) through an approved procedure.

AMC1 CAO.A.020(c) Terms of approval

ED Decision 2023/013/R FABRICATION (a) The agreement by the competent authority for the fabrication of parts by the maintenance organisation should be formalised through the approval of a detailed procedure in the CAE. This AMC contains principles and conditions to be taken into account for the preparation of an acceptable procedure.

(b) Fabrication, inspection, assembly and test should be clearly within the technical and procedural capability of the approved maintenance organisation.

(c) The approved data necessary to fabricate the part is that approved by either the Agency, the type certificate (TC) holder, the Part 21 design organisation approval holder, or the supplemental type certificate (STC) holder. Alternatively, the data can be declared by the declarant of a de claration of design compliance (in accordance with Part 21 Light Subpart C) .

(d) Items fabricated by an approved maintenance organisation may only be used by that organisation in the course of overhaul, maintenance, modifications, or repair of aircraft or components undergoing work within its own facilities. The permission to fabri cate does not constitute approval for manufacturing, or for supplying externally and the parts do not qualify for certification on EASA Form 1. This also applies to the bulk transfer or surplus inventory, in Powered by EASA eRules Page 1214 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vd (Part - CAO) (Regulation (EU) No 1321/2014) SECTION A — ORGANISATION REQUIREMENTS that locally fabricated parts are physically segregated and excluded from any delivery certification.

(e) Fabrication of parts, modification kits, etc. for onward supply and/or sale may not be conducted under a CAO approval.

(f) The data specified in point (c) may include repair procedures involving the fabrication of parts.

Where the data on such parts is sufficient to facilitate fabrication, the parts may be fabricated by an approved maintenance organisation. Care should be taken to ensure that the data includes details on part numbering, dimensions, materials, processes, and any special manufacturing techniques, special raw material specification or/and incoming inspection requirement and that the approved organisation has t he necessary capability. That capability should be defined within the CAE. Where special processes or inspection procedures are defined in the approved or declared (in accordance with Part 21 Light Subpart C) data, which are not available at the approved maintenance organisation, that organisation cannot fabricate the part unless the TC/STC holder or the declarant of a declaration of design compliance gives an approved alternative .

(g) Examples of fabrication under the scope of a CAO approval can include but are not limited to the following: (1) fabrication of bushes, sleeves and shims; (2) fabrication of secondary structural elements and skin panels; (3) fabrication of control cables; (4) fabrication of flexible and rigid pipes; (5) fabrication of electrical cable looms and assemblies; and (6) formed or machined sheet metal panels for repairs.

It is not acceptable to fabricate any item to pattern unless an engineering drawing of the item is produced which includes any necessary fabrication processes and which is accepted to the competent authority.

(h) Where a TC holder or declarant of a declaration of design compliance or an approved or declared (in accordance with Part 21 Light Subpart G) production organisation, or a production organisation using Part 21 Light Subpart R is prepared to make available complete data which is not referred to in aircraft manuals or service bulletins, but provides manufacturing drawings for items specified in parts lists, the fabrication of these items is not considered to be within the scope of a CAO approval unless agr eed otherwise by the competent authority in accordance with a procedure specified in the CAE.

(i) Inspection and identification Any locally fabricated part should be subject to an inspection stage before, separately, and preferably independently from, any inspection of its installation. The inspection should establish full compliance with the relevant manufacturing data, and the pa rt should be unambiguously identified as fit for use by stating conformity to the approved or declared (in accordance with Part 21 Light Subpart C) data. Adequate records should be maintained of all such fabrication processes including heat treatment and t he final inspections. All parts, except those with inadequate space, should carry a part number which clearly relates them to the manufacturing/inspection data. Additionally to the part number, the approved maintenance organisation’s identity should be mar ked on the part for traceability purposes.

Depending on the scope of work, other facilities are acceptable as long as protection is ensured from inclement weather and contamination. This may include, for example, working in the field or in non - aviation premises (closed or not).

(2) These facilities do not need to be individually approved by the competent authority as long as the CAE describes for each type of facility the scope of work, the tooling and equipment available, and the permitted environmental conditions (weather, contamin ation).

(3) The organisation should include, as part of the quality system/organisational review, a sampling of the compliance with these conditions during certain maintenance events.

(g) It is acceptable to combine any or all of the office accommodation requirements into one office subject to the staff having sufficient room to carry out the assigned tasks.

(h) Storage facilities for serviceable aircraft components should be clean, well ventilated and maintained at an even dry temperature to minimise the effects of condensation. The manufacturer’s storage recommendations should be followed for those aircraft components identified in such published recommendations.

(i) Adequate storage racks should be provided and strong enough to hold aircraft components and provide sufficient support for large aircraft components such that the component is not damaged during storage.

(j) All aircraft components, wherever practicable, should remain packaged in their protective material to minimise damage and corrosion during storage. A shelf life control system should be utilised and identity tags used to identify components.

(k) ‘Segregation' refers to storing unserviceable components in a separate secured location from serviceable components.

(l) Segregation and management of any unserviceable component should be ensured according to the pertinent procedure approved to that organisation.

(m) Procedures should be defined by the organisation describing the decision process for the status of unserviceable components. This procedure should identify at least the following: (1) role and responsibilities of the persons managing the decision process; (2) description of the decision process to choose between maintaining, storing or mutilating a component; and (3) traceability of decision.

(n) Once unserviceable components or materials have been identified as unsalvageable in accordance with M.A.501(a)(3) or ML.A.504(c) , the organisation should establish secure areas in which to segregate such items and to prevent unauthorised access. Unsalvageable components should be managed through a procedure to ensure that these components receive the appropriate final disposal acco rding to M.A.504(b) or ML.A.504(d) or (e). The person responsible for the implementation of this procedure should be identified.

AMC1 CAO.A.060(h) Maintenance standards

AMC2 CAO.A.060(h) Maintenance standards

ED Decision 2020/002/R INDEPENDENT INSPECTION Independent inspection is one possible error - capturing method.

(a) What is an independent inspection An independent inspection is an inspection, which is performed by an ‘independent qualified person’, of a task carried out by an ‘authorised person’, taking into account that: (1) the ‘authorised person’ is the person who performs the task or supervises the task, and assumes the full responsibility for the completion of the task in accordance with the applicable maintenance data; (2) the ‘independent qualified person’ is the person who performs the independent inspection and attests to the satisfactory completion of the task, and that no deficiencies have been found. The ‘independent qualified person’ does not issue a certificate of Powered by EASA eRules Page 1226 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vd (Part - CAO) (Regulation (EU) No 1321/2014) SECTION A — ORGANISATION REQUIREMENTS release to service (CRS); therefore, he or she is not required to hold certification privileges; (3) the CRS is issued by the ‘authorised person’ after the independent inspection has been carried out satisfactorily; and (4) the work card system should record the identification of each person, the date and the details of the independent inspection, as necessary, before the CRS is issued.

(b) Qualifications of personnel performing independent inspections The organisation should have procedures to demonstrate that the ‘independent qualified person’ has been trained and has gained experience in the specific control systems to be inspected. This training and experience could be demonstrated, for example, by: (i) holding a Part - 66 licence in the same subcategory as the licence subcategory or equivalent necessary to release or sign off the critical maintenance task; or (ii) holding a Part - 66 licence in the same category and specific training in the task to be inspected; or (iii) having received appropriate training and having gained relevant experience in the specific task to be inspected.

(c) How to perform an independent inspection The independent inspection should ensure, for example, the correct assembly, locking and sense of operation of the parts involved. When inspecting control systems that have undergone maintenance, the ‘independent qualified person’ should consider the follo wing points independently: (1) all those parts of the system that have actually been disconnected or disturbed should be inspected for their correct assembly and locking; (2) the system as a whole should be inspected for full and free movement over the complete range; (3) cables should be tensioned correctly with adequate clearance at secondary stops; (4) the operation of the control system as a whole should be observed to ensure that the controls operate in the correct sense; (5) if different control systems are interconnected so that they affect each other, all the interactions should be checked through the full range of the applicable controls; and (6) software that is part of the critical maintenance task should be checked; for example, its version and its compatibility with the aircraft configuration.

(d) What to do in unforeseen cases when only one person is available REINSPECTION (1) Reinspection is subject to the same conditions as the independent inspection is, except that the ‘authorised person’ performing the maintenance task is also acting as ‘independent qualified person’ and performs the inspection.

(2) For critical maintenance tasks, reinspection should only be used in unforeseen circumstances when only one person is available to carry out the task and perform the independent inspection. The circumstances cannot be considered to be unforeseen if the Powered by EASA eRules Page 1227 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vd (Part - CAO) (Regulation (EU) No 1321/2014) SECTION A — ORGANISATION REQUIREMENTS person or organisation has not assigned a suitable ‘independent qualified person’ to that particular task.

(3) The CRS is issued by the ‘authorised person’ after the reinspection has been performed satisfactorily.

(4) The work card system should record the identification of the ‘authorised person’ and the date and the details of the reinspection, as necessary, before the CRS is issued.

ED Decision 2020/002/R COMPONENTS MAINTAINED BY A CAO Appendix II to Part - M, point (5), blocks 12 and 14a describe how the component maintenance release is formalised by the CAO on EASA Form 1.

Used components maintained by a CAO appropriately approved for component maintenance and released on an EASA Form 1 cannot be installed on complex motor - powered aircraft or aircraft used by an air carrier licensed in accordance with Regulation (EC) No 1008 /2008.

AMC1 CAO.A.070(a) Component certificate of release to service

ED Decision 2020/002/R 1. An aircraft component which has been maintained off the aircraft requires the issuance of a CRS for such maintenance and another CRS in regard to being installed properly on the aircraft when such installation occurs. When an organisation maintains a co mponent for use by the same organisation, an EASA Form 1 may not be necessary depending upon the organisation’s internal release procedures defined in the CAE.

2. In the case of components in storage prior to Part - 145, Part - M and Part 21 and not released on an EASA Form 1 or equivalent in accordance with M.A.501(a)(1) or ML.A.501(a) , or removed serviceable from a serviceable aircraft or from an aircraft which has been withdrawn from service, the following applies: Powered by EASA eRules Page 1228 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vd (Part - CAO) (Regulation (EU) No 1321/2014) SECTION A — ORGANISATION REQUIREMENTS 2.1. An EASA Form 1 may be issued for an aircraft component which has been: − maintained before Part - 145 or Part - M became effective, or manufactured before Part 21 became effective; − used on an aircraft and removed in a serviceable condition. Examples include leased and loaned aircraft components; − removed from aircraft which have been withdrawn from service, or from aircraft which have been involved in abnormal occurrences such as accidents, incidents, heavy landings or lightning strikes; − maintained by an unapproved organisation.

2.2. An appropriately rated Part - CAO maintenance organisation may issue an EASA Form 1 as detailed in points 2.5 to 2.9, as appropriate, in accordance with the procedures detailed in the CAE as approved by the competent authority. The appropriately rated P art - CAO maintenance organisation is responsible for ensuring that all reasonable measures have been taken to ensure that only approved and serviceable aircraft components are issued with an EASA Form 1 under this point 2.

2.3. For the purposes of this point 2 only, ‘appropriately rated’ refers to an organisation with an approval class rating for the type of component or for the product in which it may be installed.

2.4. An EASA Form 1 issued in accordance with this point 2 should be issued by signing in block 14b and stating ‘Inspected/Tested’ in block 11. In addition, block 12 should specify: 2.4.1. when the last maintenance was carried out and by whom; 2.4.2. if the component is unused, when the component was manufactured and by whom with a cross reference to any original documentation which should be included in the Form; 2.4.3. a list of all airworthiness directives (ADs), repairs and modifications known to have been incorporated. If no ADs or repairs or modifications are known to be incorporated, then this should be so stated; 2.4.4. the detail of life used for service life - limited parts being any combination of fatigue, overhaul or storage life; 2.4.5. for any aircraft component having its own maintenance history record, reference to the particular maintenance history record as long as the record contains the details that would otherwise be required in block 12. The maintenance history record and acceptance test report or statement, if applicable, should be attached to EASA Form 1.

2.5. New/unused aircraft components 2.5.1. Any unused aircraft component in storage without an EASA Form 1 up to the effective date(s) for Part 21 that was manufactured by an organisation acceptable to the competent authority at the time may be issued with an EASA Form 1 by an appropriately rated maintenance organisation approved under Part - CAO. EASA Form 1 should be issued in accordance with the following points, which should be included in a procedure within the CAE.

Note 1: It should be understood that the release of a stored but unused aircraft component in accordance with this point represents a maintenance release under Powered by EASA eRules Page 1229 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vd (Part - CAO) (Regulation (EU) No 1321/2014) SECTION A — ORGANISATION REQUIREMENTS Part - CAO and not a production release under Part 21. It is not intended to bypass the production release procedure agreed by the Member State for parts and subassemblies intended for fitment on the manufacturers’ own production line.

(a) An acceptance test report or statement should be available for all used and unused aircraft components that are subject to acceptance testing after manufacturing or maintenance as appropriate.

(b) The aircraft component should be inspected for compliance with the manufacturer’s instructions and limitations for storage and condition including any requirement for limited storage life, inhibitors, controlled climate and special storage containers. In addition, or in the absence of specific storage instructions, the aircraft component should be inspected for damage, corrosion and leakage to ensure good condition.

2.5.2. If it is not possible to establish satisfactory compliance with all applicable conditions specified in point 2.5.1 (a) to (c) inclusive, the aircraft component should be disassembled by an appropriately rated organisation and subjected to a check fo r incorporated ADs, repairs and modifications and inspected/tested in accordance with the maintenance data to establish satisfactory condition and, if relevant, all seals, lubricants and life - limited parts replaced. Upon satisfactory completion after reass embly, an EASA Form 1 may be issued stating what was carried out and the reference to the maintenance data included.

2.6. Used aircraft components removed from a serviceable aircraft 2.6.1. Serviceable aircraft components removed from a Member State registered aircraft may be issued with an EASA Form 1 by an appropriately rated organisation subject to compliance with this point 2.6.1.

(a) The organisation should ensure that the component was removed from the aircraft by an appropriately qualified person.

(b) The aircraft component may only be deemed serviceable if the last flight operation with the component fitted revealed no faults on that component or related system.

(c) The aircraft component should be inspected for satisfactory condition including in particular damage, corrosion or leakage and compliance with any additional maintenance data.

(d) The aircraft record should be researched for any unusual events that could affect the serviceability of the aircraft component such as involvement in accidents, incidents, heavy landings or lightning strikes. Under no circumstances may an EASA Form 1 b e issued in accordance with this point 2.6 if it is suspected that the aircraft component has been subjected to extremes of stress, temperatures or immersion which could affect its operation.

(e) A maintenance history record should be available for all used serialised aircraft components.

(f) Compliance with known modifications and repairs should be established.

(h) Compliance with known applicable airworthiness directives should be established.

(i) Subject to satisfactory compliance with this point 2.6.1, an EASA Form 1 may be issued and should contain the information as specified in point 2.4 including the aircraft from which the aircraft component was removed.

2.6.2. Serviceable aircraft components removed from a non - Member State registered aircraft may only be issued with an EASA Form 1 if the components are leased or loaned from the maintenance organisation approved under Part - CAO that retains control of the a irworthiness status of the components. An EASA Form 1 may be issued and should contain the information as specified in point 2.4 including the aircraft from which the aircraft component was removed.

2.7. Used aircraft components removed from an aircraft withdrawn from service Serviceable aircraft components removed from a Member State registered aircraft withdrawn from service may be issued with an EASA Form 1 by a maintenance organisation approved under Part - CAO subject to compliance with this point 2.7.

(a) Aircraft withdrawn from service are sometimes dismantled for spares. This is considered to be a maintenance activity and should be accomplished under the control of an organisation approved under Part - CAO, employing procedures approved by the competent authority.

(b) To be eligible for installation, components removed from such aircraft may be issued with an EASA Form 1 by an appropriately rated organisation following a satisfactory assessment.

(c) As a minimum, the assessment will need to satisfy the standards set out in points 2.5 and 2.6 as appropriate. This should, where known, include the possible need for the alignment of scheduled maintenance that may be necessary to comply with the mainte nance programme applicable to the aircraft on which the component is to be installed.

(e) A structured plan should be formulated to control the aircraft disassembly process.

The disassembly is to be carried out by an appropriately rated organisation under the supervision of certifying staff, who will ensure that the aircraft components are removed and documented in a structured manner in accordance with the appropriate maintenance data and disassembly plan.

(f) All recorded aircraft defects should be reviewed and the possible effects these may have on both normal and standby functions of removed components are to be considered.

(g) Dedicated control documentation is to be used as detailed by the disassembly plan, to facilitate the recording of all maintenance actions and component removals performed during the disassembly process. Components found to be unserviceable are to be id entified as such and quarantined pending a decision on the actions to Powered by EASA eRules Page 1231 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vd (Part - CAO) (Regulation (EU) No 1321/2014) SECTION A — ORGANISATION REQUIREMENTS be taken. Records of the maintenance accomplished to establish serviceability are to form part of the component maintenance history.

(h) Suitable Part - CAO facilities for the removal and storage of removed components are to be used which include suitable environmental conditions, lighting, access equipment, aircraft tooling and storage facilities for the work to be undertaken.

While it m ay be acceptable for components to be removed, given local environmental conditions, without the benefit of an enclosed facility, subsequent disassembly (if required) and storage of the components should be in accordance with the manufacturer’s recommendat ions.

2.8. Used aircraft components maintained by organisations not approved in accordance with Part - M Subpart F, Part - CAO or Part - 145 For used components maintained by a maintenance organisation not approved under Part - M Subpart F, Part - CAO or Part - 145, due care should be taken before acceptance of such components. In such cases, an appropriately rated maintenance organisation approved u nder Part - CAO should establish satisfactory conditions by: (a) dismantling the component for sufficient inspection in accordance with the appropriate maintenance data; (b) replacing all service life - limited components when no satisfactory evidence of life used is available and/or the components are in an unsatisfactory condition; (c) reassembling and testing as necessary the component; and (d) completing all certification requirements as specified in CAO.A.070 .

In the case of used components maintained by an FAA Part - 145 repair station (USA) or by a TCCA CAR573 approved maintenance organisation (Canada) that does not hold an EASA Part - 145, Part - CAO or Part - M Subpart F approval, the conditions (a) through (d) desc ribed above may be replaced by the following conditions: (a) availability of a Form 8130 - 3 (FAA) or TCCA 24 - 0078 (TCCA) or an Authorized Release Certificate Form One (TCCA); (b) verification of compliance with all applicable airworthiness directives; (c) verification that the component does not contain repairs or modifications that have not been approved in accordance with Part 21; (d) inspection for satisfactory condition including in particular damage, corrosion or leakage; and (e) issuance of an EASA Form 1 in compliance with points 2.2, 2.3 and 2.4.

These alleviated requirements are based on the fact that credit can be taken for their technical capabilities and their competent authority oversight, as attested by the following documents: − Maintenance Annex Guidance (MAG) between the FAA and EASA − Maintenance Annex Guidance (MAG) between the TCCA and EASA 2.9. Used aircraft components removed from an aircraft involved in an accident or incident Such components should only be issued with an EASA Form 1 when processed in accordance with point 2.7 and a specific work order including all additional necessary tests and inspections made necessary by the accident or incident. Such a work order may Powered by EASA eRules Page 1232 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vd (Part - CAO) (Regulation (EU) No 1321/2014) SECTION A — ORGANISATION REQUIREMENTS require input from the TC holder or original manufacturer as appropriate. This work order should be referenced in block 12.

3. A certificate should not be issued for any component when it is known that the component is unserviceable except in the case of a component undergoing a series of maintenance processes at several approved maintenance organisations and the component need s a certificate for the previous maintenance process carried out for the next approved maintenance organisation to accept the component for subsequent maintenance processes. In such a case, a clear statement of limitation should be endorsed in block 12.

GM1 CAO.A.095 Privileges of the organisation

ED Decision 2020/002/R A CAO can be approved to perform airworthiness reviews although it does not hold the privileges of continuing airworthiness management (for aircraft to which Part - ML is applicable). This means that the certificate will show the boxes ‘maintenance’ and ‘air worthiness reviews’ ticked.

AMC1 CAO.A.095(b)(3) Privileges of the organisation

ED Decision 202 1 /009/R SUBCONTRACTING OF CONTINUING AIRWORTHINESS TASKS (a) The CAO may subcontract certain continuing airworthiness management tasks to qualified organisations. The subcontracted organisation performs the continuing airworthiness management tasks as an integral part of the CAO quality system, irrespective of a ny other approval held by the subcontracted organisation (including CAMO, CAO or Part - 145 approval).

(b) The CAO remains accountable for the satisfactory completion of the continuing airworthiness management tasks irrespective of any contract that may be established.

(c) In order to fulfil this responsibility, the CAO should be satisfied that the actions taken by the subcontracted organisation meet the standards required by Part - CAO. Therefore, the CAO management of such activities should be accomplished by: (1) active control through direct involvement; and/or (2) endorsing the recommendations made by the subcontracted organisation.

(d) In order to retain ultimate responsibility, the CAO should limit subcontracted tasks to the activities specified below: ( 1 ) airworthiness directive analysis and planning; ( 2 ) service bulletin analysis; ( 3 ) planning of maintenance; ( 4 ) reliability monitoring, engine health monitoring; ( 5 ) maintenance programme development and amendments; and ( 6 ) any other activities, which do not limit the CAO responsibilities, as agreed by the competent authority.

(e) The CAO’s controls associated with subcontracted continuing airworthiness management tasks should be reflected in the associated contract and be in accordance with the CAO policy and procedures defined in the CAE. When such tasks are subcontracted, the quality system is considered to be extended to the subcontracted organisations.

(f) With the exception of engines and auxiliary power units, contracts would normally be limited to one organisation per aircraft type for any combination of the subcontracted activities. Where contracts are made with more than one organisation, the CAO sh ould demonstrate that adequate coordination controls are in place and that the individuals’ responsibilities are clearly defined in the related contracts.

(g) Contracts should not authorise the subcontracted organisation to subcontract elements of the continuing airworthiness management tasks to other organisations.

The contracts should be acceptable to the competent authority. The CAO should only subcontract to organisations which are specified by the competent authority on EASA Form 3 - CAO (page 2, block titled ‘List of organisation(s) working under a quality system’).

(i) The subcontracted organisation should agree to notify the CAO of any changes affecting the contract as soon as practical. The CAO should then inform its competent authority. Failure to do so may invalidate the competent authority’s acceptance of the co ntract.

(j) Appendix II to AMC1 CAMO.A.125(d)(3) provides information on the subcontracting of continuing airworthiness management tasks by the CAMO. The same principles may be applied to the CAO.

CAO.A.100 Quality system and organisational review

Regulation (EU) 2019/1383 (a) To ensure that the CAO continues to meet the requirements of this Annex, this organisation shall establish a quality system and designate a quality manager.

(b) The quality system shall monitor the carrying out of the activities of the organisation covered by this Annex. It shall monitor in particular: (1) that all those activities are performed in accordance with the approved procedures; (2) that all contracted maintenance tasks are carried out in accordance with the contract; (3) that the organisation continues to comply with the requirements of this Annex.

(d) Where the organisation holding a CAO approval is additionally approved in accordance with an Annex other than this Annex, the quality system may be combined with that required by the other Annex.

(e) A CAO shall be considered as a small CAO when one of the following condition is met: (1) the scope of the CAO does only contain aircraft covered by Part - ML.

(2) the CAO does not exceed 10 full - time equivalent staff involved in maintenance.

(3) the CAO does not exceed 5 full - time equivalent staff involved in continuing airworthiness management.

(f) In the case of a small CAO, the quality system may be replaced by regular organisational reviews, subject to the approval of the competent authority. In that case, the CAO shall not contract continuing airworthiness management tasks to other parties.

GM1 CAO.A.100(a) Quality system and organisational review

ED Decision 2020/002/R QUALITY SYSTEM — GENERAL (a) The primary objectives of the quality system are to provide an independent monitoring function on how the organisation ensures compliance with the applicable requirements, policies and procedures, and to request actions where non - compliances are identi fied.

(b) The independence of the quality system is established by always ensuring that audits are carried out by personnel who are not responsible for the functions, procedures or products that are audited.

Powered by EASA eRules Page 1238 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vd (Part - CAO) (Regulation (EU) No 1321/2014) SECTION A — ORGANISATION REQUIREMENTS

AMC1 CAO.A.100(a) Quality system and organisational review

ED Decision 2020/002/R QUALITY SYSTEM — FEEDBACK (a) The quality system should include a feedback system: it should ensure that all findings resulting from the independent audits are properly investigated and corrected in a timely manner. It should address who is required to rectify each non - compliance and the procedure to be followed if rectification is not completed within appropriate timescales. The procedure should enable the accountable manager to be kept informed of any safety issues and the extent of compliance with Part - CAO.

(b) The audit reports referenced in AMC1 CAO.A.100(b) should be sent to the relevant department for rectification action giving target rectification dates. Rectification dates should be discussed with such department before the quality department or nominated auditor confirms such dates in the report. The re levant department is required to rectify findings and inform the quality manager or the auditor of such rectification.

(c) The accountable manager should hold regular meetings with staff to check the progress of any corrective actions. If these meetings are delegated to the quality manager on a day - to - day basis, then the accountable manager should: (1) meet the senior staff involved at least twice per year to review the overall performance of the compliance monitoring function; and (2) receive at least a half - yearly summary report on non - compliance findings.

AMC1 CAO.A.100(b) Quality system and organisational review

ED Decision 2020/002/R QUALITY SYSTEM — INDEPENDENT AUDIT (a) An essential element of the quality system is the independent audit.

(b) The independent audit should be an objective process of routine sample checks of all aspects of the organisation’s ability to carry out continuing airworthiness management and/or maintenance to the standards required by Regulation (EU) No 1321/2014. It should include some product sampling (e.g. product audit) as this is the end result of the process.

(c) The independent audit should provide an objective overview of the complete set of continuing - airworthiness - management - and/or maintenance - related activities.

(d) The organisation should establish an audit plan to show when and how often the activities as required by Part - M, Part - ML and Part - CAO will be audited.

(e) The audit plan should ensure that all aspects of Part - CAO compliance are verified every year, including all the subcontracted activities, and the auditing may be carried out as a complete single exercise or (sub)divided over the annual period. The inde pendent audit should not require each procedure to be verified against each product line when it can be shown that the particular procedure is common to more than one product line and the procedure has been verified every year without resultant findings. W here findings have been identified, the particular procedure should be verified against other product lines until the findings have been rectified, after which the independent audit procedure may revert to a 1 - year interval for the particular procedure.

(f) Provided that there are no safety - related findings, the audit planning cycle specified in this AMC may be increased by up to 100 %, subject to agreement by the competent authority.

Regulation (EU) 2020/270 (a) Within the approval class(es) and rating(s) established by the competent authority, the scope of work specified in the CAE defines the exact limits of approval. It is therefore essential that the approval class(es) and rating(s) and the organisations scope of work are matching.

(b) An aircraft rating, in relation to the maintenance privileges, means that the CAO may carry out maintenance on the aircraft and any component (including engines), in accordance with aircraft maintenance data or, if agreed by the competent authority, in acc ordance with component maintenance data, only whilst such components are fitted to the aircraft. Nevertheless, such aircraft - rated CAO may temporarily remove a component for maintenance in order to improve access to that component except when such remo val creates the need for additional maintenance not eligible for the requirements of point (b). This will be subject to a control procedure in the CAE to be approved by the competent authority.

(c) An engine rating (turbine, piston or electrical) means that the CAO may carry out maintenance on the uninstalled engine and engine components, in accordance with engine maintenance data or, if agreed by the competent authority, in accordance with component maintenance data, only whilst such components are fitted to the engine. Nevertheless, such engine - rated CAO may temporarily remove a component for maintenance in order to improve access to that component except when such removal creates the need for a dditional maintenance not eligible for the requirements of point (c). An engine - rated CAO may also carry out maintenance on an installed engine during base and line maintenance subject to a control procedure in the CAE to be approved by the competent autho rity.

(d) A component rating (other - than - complete engines) means that the CAO may carry out maintenance on uninstalled components (excluding complete engines) intended for fitment to the aircraft or engine. This CAO may also carry out maintenance on an installed com ponent (other - than - complete engines) during base and line maintenance or at an engine maintenance facility subject to a control procedure in the CAE to be approved by the competent authority.

(e) An non - destructive testing (NDT) rating is a self - contained rating not necessarily related to a specific aircraft, engine or other component. The NDT rating is only necessary for a CAO that carries out NDT as a particular task for another organisation. A C AO approved with an aircraft, engine or component rating may carry out NDT on products they are maintaining subject to the CAE containing NDT procedures, without the need for an NDT rating.

Appendix II to AMC1 CAO.A.100(f) — Organisational review

ED Decision 2023/013/R Depending on the complexity of the small organisation (number and type of aircraft, number of different fleets, privilege to perform airworthiness reviews, etc.), the organisational review system may vary from a system using the principles and practices of a quality system (except for the requirement of independence) to a simplified system adapted to the low complexity of the organisation and the aircraft managed.

As a core minimum, the organisational review system should have the following features, which should be described in the CAE: (a) Identification of the person responsible for the organisational review programme By default, this person should be the accountable manager, unless he or she delegates this responsibility to (one of) the CAO.A.035(b) person(s).

(b) Identification and qualification criteria for the person(s) responsible for performing the organisational reviews These persons should have a thorough knowledge of the regulations and of the organisation procedures. They should also have knowledge of audits, acquired through training or through experience (preferably as an auditor, but also possibly because they activ ely participated in several audits conducted by the competent authority).

(c) Elaboration of the organisational review programme (1) Checklist(s) covering all items necessary to be satisfied that the organisation delivers a safe product and complies with the regulation. All procedures described in the CAE should be addressed.

(2) A schedule for the accomplishment of the checklist items. Each item should be checked at least every 12 months. The organisation may choose to conduct one full review annually or to conduct several partial reviews.

(d) Performance of organisational reviews Each checklist item should be answered using an appropriate combination of: − review of records, documentation, etc.; − sample check of aircraft under contract or being maintained under a work order; − interview of personnel involved; − review of discrepancies and internal reports (e.g. notified difficulties when using current procedures and tools, systematic deviations from procedures, etc.); − review of complaints filed by customers.

(e) Management of findings and occurrence reports All findings should be recorded and notified to the affected persons.

(1) All findings that lower the safety standard and seriously hazard flight safety should be immediately notified to the competent authority and all necessary actions on aircraft in service should be immediately taken.

(2) All occurrence reports should be reviewed with the aim of continuous improvement of the system by identifying possible corrective and preventive actions. This should be done in order to find prior indicators (e.g. notified difficulties when using curre nt procedures Powered by EASA eRules Page 1260 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vd (Part - CAO) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM TO ANNEX Vd (Part - CAO) and tools, systematic deviations from procedures, unsafe behaviours, etc.), and dismissed alerts that, had they been recognised and appropriately managed before the event, could have resulted in the undesired event being prevented.

(3) Corrective and preventive actions should be approved by the person responsible for the organisational review programme and implemented within a specified time frame.

(4) Once the person responsible for the organisational review programme is satisfied that the corrective action is effective, the closure of the finding should be recorded along with a summary of the corrective action.

(5) The accountable manager should be notified of all significant findings and, on a regular basis, of the global results of the organisational review programme.

Below is a typical example of a simplified organisational review checklist, to be adapted as necessary to cover the CAE procedures used and the privileges held by the organisation: 1. Scope of work − Check that all aircraft under contract are covered in EASA Form 3 - CAO .

− Check that the scope of work in the CAE is consistent with EASA Form 3 - CAO.

− Check that no work has been performed outside the scope of EASA Form 3 - CAO and the CAE.

− Is it justified to retain in the approved scope of work aircraft types for which the organisation has no longer aircraft under contract?

2. Maintenance data − Check that the maintenance data is present and up to date for the ongoing maintenance activity.

− Check that no change has been made to the maintenance data from the design approval holder (DAH) or the declarant of a declaration of design compliance without the DAH or declarant being notified .

3. Equipment and tools − Check the availability of maintenance equipment and tools against the lists in the CAE and check if they are still appropriate with regard to the maintenance data.

− Check tools for proper calibration (sample check).

4. Stores − Do the stores meet the criteria of the CAE procedures?

− Check by sampling some items in the store for presence of proper documentation and any overdue items.

5. Certification of maintenance − Has maintenance on products and components been properly certified?

− Have implementations of modifications/repairs been carried out with appropriate approval of such modifications/repairs (sample check)?

6. Maintenance contracted Powered by EASA eRules Page 1261 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vd (Part - CAO) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM TO ANNEX Vd (Part - CAO) − Sample check of maintenance records: − Existence and adequacy of the work order; − Data received from the maintenance organisation: − valid CRS including any deferred maintenance; − list of removed and installed components and copy of the associated EASA Form 1 or equivalent.

− Obtain a copy of the current approval certificate (EASA Form 3) of the maintenance organisations contracted.

7. Maintenance subcontracted Check that subcontractors for specialised services are properly controlled by the organisation.

8. Relations with the owners/operators — maintenance − Has maintenance been carried out with suitable work orders?

− When a maintenance contract has been signed with an owner/operator, have the obligations of the contracts been respected by both parties?

9. Relations with the owners/operators — continuing airworthiness management − Has a contract (in accordance with Appendix I to Part - M or Appendix I to Part - M L) been signed with each external owner/operator, covering all the aircraft whose airworthiness is managed by the CAO?

− Have the owners/operators under contract fulfilled their obligations identified in the contract? As appropriate: − Are the pre - flight checks correctly performed? (interview of pilots) − Is the technical log or equivalent correctly used (record of flight hours/cycles, defects reported by the pilot, identification of what maintenance is next due, etc.)?

− Have flights occurred with overdue maintenance or with defects not properly rectified or deferred? (sample check from the aircraft records) − Has maintenance been performed without notifying the CAO (sample check from the aircraft records, interview of the owner/operator)?

10. Maintenance records − Have the maintenance actions been properly recorded?

− Perform a sample check of maintenance records (including EASA Form 1 or equivalent, and certificates of conformity) to ensure completeness and storage during the appropriate periods.

11. Continuing airworthiness records − Perform a sample check of continuing airworthiness records to ensure completeness and storage during the appropriate periods.

− Is storage of computerised data properly ensured?

12. Airworthiness review and permit to fly records Powered by EASA eRules Page 1262 of 1265 | Sep 2025 Easy Access Rules for Continuing Airworthiness Annex Vd (Part - CAO) (Regulation (EU) No 1321/2014) APPENDICES TO AMC AND GM TO ANNEX Vd (Part - CAO) Perform a sample check of airworthiness review and permit to fly records to ensure completeness and storage during the appropriate periods.

13. Airworthiness situation of the fleet Does the continuing airworthiness status (AD, maintenance programme, life - limited components, deferred maintenance, ARC validity) show any expired items? If so, are the aircraft grounded?

14. Aircraft maintenance programme (AMP) development and control − For Part - ML aircraft, ensure that the AMP has been approved by the CAO and has been subject to annual review.

− For Part - M aircraft, check that all revisions to the DAH or the declarant of a declaration of design compliance instructions for continuing airworthiness (ICA), since the last review, have been (or are planned to be) incorporated in the maintenance programme, unless otherwise approved by the competent authority.

− Has the maintenance programme taken into account all modifications or repairs?

− Have all maintenance programme amendments been approved at the right level (CAO, competent authority or indirect approval)?

− Does the status of compliance with the maintenance programme reflect the latest approved maintenance programme?

− How has the organisation managed: − the tolerances (variations) to the AMP intervals?

− the deviations from the maintenance tasks to be performed in accordance with the AMP?

− Have the deviations from the DAH or the declarant of a declaration of design compliance ICA in the development of the AMP been properly justified and recorded?

15. ADs (and other safety measures mandated by the competent authority or EASA) − Have all ADs issued since the last review been incorporated into the AD status?

− Does the AD status correctly reflect the AD content: applicability, compliance date, periodicity, etc.? (sample check on ADs) 16. Modifications/repairs − Are all modifications/repairs listed in the corresponding status approved in accordance with M.A.304 or ML.A.304 ? (sample check on modifications/repairs) − Have all the modifications/repairs which have been installed since the last review been incorporated in the corresponding status? (sample check from the aircraft/component logbooks or equivalent) 17. Personnel − Check that the current accountable manager and other nominated persons are correctly identified in the approved CAE.

− If the number of personnel has decreased or if the activity has increased, check that the organisation has still sufficient and adequate staff.
