A multi-engined helicopter designed with engine and system isolation features specified in Part IVB of ICAO Annex 8 and capable of operations using take-off and landing data scheduled under a critical engine failure concept which assures adequate designated surface area and adequate performance capability for continued safe flight or safe rejected take-off. Category B Helicopter. A single-engine or multi-engined helicopter which does not meet Category A standards. Category B helicopters have no guaranteed capability to continue safe flight in the event of an engine failure, and a forced AN-1A P.1 31 July 2022 landing is assumed. Commercial air transport operation. An aircraft operation involving the transport of passengers, cargo or mail for remuneration or hire. Continuing Airworthiness. The set of processes by which an aircraft, engine, propeller or part complies with the applicable airworthiness requirements and remains in a condition for safe operation throughout its operating life. Continuing Airworthiness Records. Records which are related to the continuing airworthiness status of an aircraft, engine, propeller or associated part. Critical Power-Unit(s). The power-unit(s) failure of which gives the most adverse effect on the aircraft characteristics relative to the case under consideration. Note: On some aircraft there may be more than one equally critical power-unit. In this case, the expression “the critical power-unit” means one of those critical power-units. Derived Version of an Aeroplane. An aeroplane which, from the point of view of airworthiness, is similar to the noise certificated prototype but incorporates changes in type design which may affect its noise characteristics adversely. Note 1: Where the certificating authority finds that the proposed change in design, configuration, power or mass is so extensive that a substantially new investigation of compliance with the applicable airworthiness regulations is required, the aeroplane should be considered to be a new type of design rather than a derived version. Note 2: “Adversely” refers to an increase of more than 0.10 dB in any one of the noise certification levels unless the cumulative effects of changes in type design are tracked by an approved procedure in which case “adversely” refers to a cumulative increase in the noise level in any one of the noise certification levels of more than 0.30 dB or the margin of compliance, whichever is smaller. Derived Version of a Helicopter. A helicopter which, from the point of view of airworthiness, is similar to the noise certificated prototype but incorporates changes in type design which may affect its noise characteristics adversely. Note 1: In applying the Standards of ICAO Annex 16 Volume I, a helicopter that is based on an existing prototype but which is considered by the certificating authority to be a new type design for airworthiness purposes shall nevertheless be considered as a derived version if the noise source characteristics are judged by the certificating authority to be the same as the prototype. Note 2: “Adversely” refers to an increase of more than 0.30 EPNdB in any one of the noise certification levels for helicopters certificated according to ICAO Annex 16 Volume I Part II Chapter 8 and 0.30 dB(A) in the certification level for helicopters certificated according to ICAO Annex 16 Volume I Part II Chapter 11. 31 July 2022 AN-1A P.2 Director-General.

Such personnel are the holders of an Aircraft Maintenance Licence issued under HKAR-66. The responsibilities apply when issuing certifications either as a Type Rated licence holder or a certifying staff holding a certification authorisation. It also describes the privileges of the various Type Rated licences. It should be noted that when the holders of a licence is performing maintenance activities on an aircraft on which he or she is not appropriately licensed, i.e. acting as a non-certifying staff, they are still expected to act responsibly and carry out such work in accordance with the procedures and standards identified in the following paragraphs. A licence issued by the Director-General does not confer any certification privileges with respect to aircraft which are not registered in Hong Kong unless the licence holder is entitled to certify for such activities by way of having the licence validated by the relevant Airworthiness Authority and/or is authorised by a maintenance organisation approved by that Authority. NOTES: (1) A HKAR-66 Aircraft Maintenance Licence does not normally confer any certification privileges on the holder in their own right (except for that allowed under Airworthiness Notice No. 10). Such licence must be used in conjunction with a certification authorisation. See paragraph 1.10. (2) In the context of this Notice, reference to an authorisation means an authorisation issued by a HKAR-145 approved maintenance organisation to allow the holder to issue Certificate of Release to Service within the limitations shown on the authorisation. 1.1 The Certificate referred to under Article 9 of the Air Navigation (Hong Kong) Order 1995 (‘the Order’) is a Certificate of Maintenance Review to be issued following completion of the review required by the Order. The certificate 31 October 2024 AN-3 P.2 referred to under Article 11 of the Order is a Certificate of Release to Service to be issued on completion of maintenance of aircraft or components, either required or not required to be maintained under the provisions of HKAR-145. 1.2 In connection with the issue of Certificate of Release to Service, the following definitions apply: (a) Maintenance means the performance of tasks on an aircraft, engine, propeller or associated part required to ensure the continuing airworthiness of an aircraft, engine, propeller or associated part including any one or combination of overhaul, inspection, replacement, defect rectification, and the embodiment of a modification or repair. (b) Overhaul means the restoration of an aircraft/aircraft component by inspection and replacement in conformity with an approved standard to extend the operational life. (c) Repair means the restoration of an aircraft, engine, propeller or associated part to an airworthy condition in accordance with the appropriate airworthiness requirements after it has been damaged or subjected to wear. (d) Inspection means the examination of an aircraft/aircraft component to establish conformity with an approved standard. (e) Replacement is any work operation which involves the removal and replacement of the same part or the substitution of an approved alternative part. (f) Modification is a change to the type design of an aircraft, engine or propeller. NOTE 1: A modification may also include the embodiment of the modification which is a maintenance task subject to a maintenance release. NOTE 2: Defect rectification normally consists of an element of inspection and troubleshooting followed by repair and replacement of the defective item. NOTE 3: Inspection includes: (i) Mandatory Inspection, an inspection classified as Mandatory by the Director-General, where the inspection itself is the work. (ii) Scheduled Maintenance Inspection, an inspection or maintenance including tests required by the Approved Maintenance Schedule or Programme. 1.3 Although many terms in common usage describe the various aspects of aircraft engineering, the meanings assigned to such terms are not always the same. For the purpose of this Notice, in relation to airworthiness, the 31 October 2024 AN-3 P.3 following definitions apply: (a) Condition – the physical state of an item. (b) Assembly – that items are fitted, assembled, attached, installed, connected, secured or adjusted in the approved manner. (c) Functioning – operation in the approved manner achieving such performance, range of movement and freedom of movement as may be specified. The certifying staff shall be responsible for the condition, assembly and functioning of the aircraft or its components for maintenance that has been certified under the privileges of a Type Rated licence or an authorisation. 1.4 The certifying staff shall be responsible for ensuring that work is performed and recorded in a satisfactory manner taking into account the following: (a) Whenever work is carried out on an aircraft, it is the duty of all persons to whom this Notice applies to ensure that the work, for which they are responsible, progresses in a managed and controlled manner. Where they are supported by additional staff to carry out the work, consideration shall be given by them before starting the work to the manpower resource available and the abilities of the staff concerned. This is to ensure that the certifying staff determines and exercises an adequate degree of supervision over such staff. (b) In relation to work carried out on an aircraft, it is the duty of all persons to whom this Notice applies to ensure that an adequate record of the work carried out is maintained. This is particularly important where such work is carried on beyond a working period or shift, or is handed over from one person to another. The work accomplished, particularly for disassembly or disturbance of components or aircraft systems, should be recorded as the work progresses or prior to undertaking a disassociated task. In any event, records should be completed no later than the end of the work period or shift of the individual undertaking the work. Such records should include 'open' entries to reflect the remaining actions necessary to restore the aircraft to a serviceable condition prior to release to service. In the case of complex tasks which are undertaken frequently, consideration should be given to the use of pre-planned stage sheets to assist in the control, management and recording of these tasks. Where such sheets are used, care must be taken to ensure that they accurately reflect the current requirements and recommendations of the manufacturer and that all key stages, inspections, or replacements are recorded. (c) It is also the duty of all persons to whom this Notice applies to 31 October 2024 AN-3 P.4 consider the effect such work may have, directly or indirectly, on items which are the responsibilities of other such persons. In all cases where an overlap of responsibility between licence categories occurs, the person primarily responsible for the item must involve all other trade disciplines affected. Every person to whom this Notice applies must therefore be conversant with all other relevant paragraphs of this Notice. Certificate of Release to Service for each relevant trade category must be issued by all persons concerned, each assuming responsibility of and certifying those aspects of the work for which the licence/authorisation holder is entitled to assume responsibility. 1.5 A Certificate of Release to Service shall only be issued on completion of maintenance when the signatory is satisfied that the work has been properly carried out and accurately recorded, having due regard to the use of: (a) up-to-date instructions and maintenance data (including manuals, drawings, specifications, CAD mandatory modifications/inspections, and, where applicable, company procedures); (b) recommended tooling and test equipment which has a valid calibration record where applicable; and (c) a working environment appropriate to the work being carried out. When issuing a Certificate of Release to Service for work performed by others, the certifying staff assumes responsibility. The certifying staff must have inspected a sufficiently representative sample of the work and the associated documentation, and be satisfied with the competence of the persons who have performed the work. For complex tasks this may require progressive inspections to be carried out as the work proceeds. In the case of an aircraft or component where welding a metallic part is considered essential to airworthiness, it is the responsibility of the certifying staff to establish that the welder is approved in accordance with the requirements in HKAR-145. NOTE: HKAR-66 Aircraft Maintenance Licence holders certifying under the privileges of their licences may not deviate from the manufacturer's maintenance instruction or maintenance data, nor use alternative parts, components or assemblies unless such deviation is supported by the written agreement of the manufacturer, approved as a modification or agreed by the Director-General. The Director-General should be consulted in cases of difficulty. Certifying staff shall comply with all company procedures covering such issues. 1.6 (a) When the work involves the assembly or any disturbance of a vital point or control system, the independent inspection required must be completed and certified before the relevant Certificate of Release to Service is issued. 31 October 2024 AN-3 P.5 NOTES: Vital Point (1) Any point on an aircraft at which single mal-assembly could lead to catastrophe, i.e. result in loss of aircraft and/or in fatalities. (2) Certain parts in an aircraft's structure or system (including controls and control systems) which are vital to the safety of the aircraft, are not only designed to achieve the appropriate high integrity but are also dependent upon specified maintenance actions to safeguard their integrity throughout the life of the aircraft. Maintenance tasks that involve the assembly or any disturbance of a vital point that, if errors occurred, could result in a failure, malfunction, or defect endangering the safe operation of the aircraft should be considered as flight safety sensitive maintenance tasks needing independent inspections. (3) For some aircraft, the vital points are identified and listed in the maintenance documents. For those aircraft where no such identification and listing of vital points has been provided, an operator with the necessary Design Approval or otherwise in consultation with a competent design organisation, may identify and list such points and apply to the Director-General to have the list incorporated in the aircraft maintenance documents. Provided such a list is accepted by the Director-General the operator need then carry out independent inspections following disturbance of the listed points only. (4) For rotorcraft, vital points shall be identified and the list shall be incorporated in the aircraft maintenance documents as described in NOTE (3). (5) For fixed wing aircraft, if no arrangement such as described in NOTE (3) has been agreed by the Director-General, the need for independent inspection of all control systems will remain. (b) The holder of a Type Rated HKAR-66 Licence in Category B1 may make certification on aircraft (or their engines, as appropriate) below 5700 kg Maximum Total Weight Authorized for independent inspections of minor adjustments to control systems on other types within the Category in which the licence is Type Rated. NOTE: A minor adjustment is considered to be a single point adjustment or reassembly of a control. 1.7 The holder of an appropriately Type Rated HKAR-66 licence in Category B1 may issue a Certificate of Release to Service to cover Non-Destructive Test Inspections on aircraft or components, within the privileges of the licence or authorisation held, subject to the work being carried out as follows: (a) Inspection requiring the use of Field Kit for the Colour Contrast Dye Penetrant technique may be carried out by persons either Type Rated as above or persons qualified in accordance with HKAR-145. (b) Non-Destructive Test Inspections requiring any other technique, including Fluorescent Penetrant Dye, shall be carried out and signed for by persons appropriately qualified in accordance with HKAR-145. 31 October 2024 AN-3 P.6 1.8 Use of either a Type Rated licence or an authorisation to issue a certification requires that, in addition to the licence or authorisation being valid at the time of certification, the holder has been engaged for periods totalling at least 6 months during the 24 months preceding the date of the certification on work affording experience comparable with that required for the grant of the licence/authorisation. 1.9 A Type Rated licensed certifying staff may issue the certificates identified below in relation to aircraft for which the licence is Type Rated and in accordance with the privileges detailed in the remaining paragraphs to this Notice. An authorised certifying staff may only issue these certificates as permitted within the limitations shown on the authorisation. (a) Certificate of Release to Service for aircraft not required to be maintained under HKAR-145 — the holder of an appropriately Type Rated licence may issue Certificate of Release to Service. (b) Certificate of Maintenance Review — the Director-General will specify who may issue a Certificate of Maintenance Review. For an organisation approved in accordance with HKAR-145 the signatory will be a person authorised in accordance with the related Airworthiness Notice. For all other cases the signatory will be an engineer possessing an appropriately type rated HKAR-66 Category B or C Licence which entitles him to issue such certificate. (c) Certificate of Fitness for Flight — the holder of an appropriately Type Rated HKAR-66 licence in Category B1 may issue Certificate of Fitness for Flight subject to compliance with the related Airworthiness Notice. 1.10 HKAR-66 Aircraft Maintenance Licences (Aircraft Maintenance Licence with Type Ratings, if applicable) may be used to allow the grant of an authorisation within a HKAR-145 approved maintenance organisation. In addition to the foregoing paragraphs, when working within such organisations, the licensed certifying staff should be aware that he/she is part of a comprehensive maintenance system. It is therefore important to realise that company procedures may further define, or require specific actions, as to how certain issues are to be dealt with and these procedures must be adhered to. It is also important to realise that when working within a HKAR-145 approved maintenance organisation and certifying under the privileges of an authorisation the licensed certifying staff is not certifying under the privileges of the licence. 2 Compass Compensation and Adjustment The Paragraph 15 Type Rating of Airworthiness Notice No. 10 permits the issue of Certificate of Release to Service by the holder in respect of the compensation and 31 October 2024 AN-3 P.7 adjustment of direct and remote reading compasses on any aircraft not subject to the requirement of HKAR-145. 3 HKAR-66 Category A Aircraft Maintenance Licence 3.1 A HKAR-66 Category A Aircraft Maintenance Licence may be issued to a person who has demonstrated a competence to complete minor scheduled line maintenance and simple defect rectification. The licence does not entitle the holder to exercise any certification privileges in respect of aircraft until the holder is issued with a corresponding certification authorisation. Such authorisations will be issued by a HKAR-145 maintenance organisation appropriately approved by the Director-General. NOTE: The holder of a HKAR-66 Category B1 licence is also qualified as a HKAR-66 Category A licence holder in the same sub-category, e.g. Aeroplanes Turbine, and may be issued with HKAR-66 Category A certification authorisation. 3.2 These HKAR-66 Category A privileges will be limited to the performance and certification of specific simple maintenance tasks, either individually or in combination, as defined in HKAR-145 AMC 145.30(g) and will require a combination of theoretical and practical training to be undertaken on each aircraft type to qualify for the task authorisation. Such authorisation, issued by a HKAR-145 approved maintenance organisation will specify the limitations of the privileges that may be applicable. HKAR-66 licence holders will therefore be required to act in accordance with the authorisation procedures of the company concerned. 3.3 HKAR-66 Category A licences are issued in licence sub-categories which are: A1 Aeroplanes Turbine A2 Aeroplanes Piston A3 Helicopters Turbine A4 Helicopters Piston 4 HKAR-66 Category B1 Aircraft Maintenance Licence 4.1 A HKAR-66 Category B1 Aircraft Maintenance Licence may be issued to a person who has demonstrated a competence to complete maintenance, including aircraft structure, powerplant and mechanical and electrical systems. Replacement of avionic line replaceable units, requiring simple tests to prove their serviceability, shall also be included in the privileges. The HKAR-66 Category B1 licence is primarily intended to be used for the purposes of qualification of line maintenance staff for authorisation. The licence, in its own right, does not entitle the holder to exercise any certification privileges in respect of aircraft and will be used in conjunction with a HKAR-145 certification authorisation. 4.2 Such authorisation will be issued by a HKAR-145 maintenance organisation appropriately approved by the Director-General. HKAR 145.30(g) requires 31 October 2024 AN-3 P.8 it to be used as a prerequisite for authorisation of staff acting as inspectors or supervisors within base maintenance (base maintenance technicians). HKAR-66 licence holders will therefore act in accordance with the authorisation procedures of the company concerned. 4.3 HKAR-66 Category B1 licences apply to all aircraft (aeroplanes and helicopters) and are issued in licence sub-categories which are: B1.1 Aeroplanes Turbine B1.2 Aeroplanes Piston B1.3 Helicopters Turbine B1.4 Helicopters Piston NOTES: (1) An unrestricted Category B1 sub-category entitles the holder to be granted Category A certification authorisations in the same sub-category, e.g. Aeroplanes Turbine. (2) An unrestricted Category B1.2 sub-category permits the holder to be granted Category B3 certification authorisations. (3) An unrestricted Category B1.2 or B3 sub-category permits the holder to issue Certificate of Release to Service for simple light aeroplanes after a base maintenance check in the case that such aeroplanes are maintained in a HKAR-145 organisation, 4.4 HKAR-66 Category B1 certification authorisations allow the holder to issue Certificate of Release to Service under HKAR 145.50 for line maintenance on aircraft which are endorsed as individual types on the licence and the corresponding authorisation. HKAR-66 Category B1 licences to the full HKAR-66 standard include scope to allow the issue of a certification authorisation covering work on a combination of the following disciplines: • airframe and their related systems; • engines and their related systems (including Auxiliary Power Units); • electrical power generation and distribution systems (power distribution in respect of airframe and/or engine systems) including lighting systems (this includes all electrical components in mechanical systems such as sensors, motors and control units); • avionic line replaceable units (LRU). In respect of avionic LRUs, the work is limited to cases where the serviceability of the system can be established by a simple self test facility (BITE) or by using simple test equipment and it is expected that, for reference purposes, a list of such components will be prepared for each aircraft type by the HKAR-145 approved maintenance organisation. (Defect rectification on avionic systems which requires an element of decision making in its application – other than a simple go/no go decision – cannot be certified). 31 October 2024 AN-3 P.9 NOTE: The HKAR-66 Category B1 licence holder is not entitled to certify for any overhaul work. 4.5 The certification authorisation can only be issued by a HKAR-145 approved maintenance organisation when the HKAR-66 Aircraft Maintenance Licence holder has the appropriate basic sub-category listed and the aircraft type rating endorsed on the licence. The type training for a HKAR-66 Category B1 type endorsement, conducted under a HKAR-147 approval, will represent the appropriate technologies as specified in HKAR-66. The certification authorisation will specify the privileges for the individual, giving due regard to the company scope of approval and any associated procedures agreed with the Director-General, and will specify any limitations to the authorisation accordingly. NOTE: A HKAR-66 licence issued on the basis of 'protected rights' may contain technical restrictions equivalent to the limitations of any HKAR-AMEL licence or company authorisations previously held. These 'protected rights' under HKAR-66 are a continuation of certification privileges under an existing licence or certification authorisation which allows current personnel to continue working and certifying without the need to re-qualify. The recognition of these privileges is shown by the inclusion of code 999 against that type rating. Authorisations issued by a HKAR-145 approved maintenance organisation should therefore be similarly restricted in scope. It should be noted that conversion to the full HKAR-66 licence standard is optional. 4.6 HKAR-66 Category B1 licences may also be issued with an endorsement allowing the certification, under the provisions of Articles 9 and 11 of the Order, for work outside of a HKAR-145 approved maintenance organisation on aircraft which are not operated for commercial air transport. Such privileges are limited to Hong Kong registered aircraft only. Certifications may only be made for those aircraft types which are endorsed individually or as Group Type Ratings on the licence. The privileges of the endorsement will reflect the certification limitations on the licence. 5 HKAR-66 Category B2/B2* Aircraft Maintenance Licence 5.1 A HKAR-66 Category B2/B2* Aircraft Maintenance Licence may be issued to a person who has demonstrated a competence to complete maintenance on avionic and electrical systems. The HKAR-66 Category B2/B2* licence is primarily intended to be used for the purposes of qualification of avionic line maintenance staff for authorisation. The licence, in its own right, does not entitle the holder to exercise any certification privileges in respect of aircraft and will be used in conjunction with a HKAR-145 certification authorisation. 5.2 Such authorisations will be issued by a HKAR-145 maintenance organisation appropriately approved by the Director-General. HKAR 145.30(h) also requires it to be used as a prerequisite for authorisation of staff acting as inspectors or supervisors within base maintenance (base maintenance technician). HKAR-66 licence holders will therefore act in accordance with the authorisation procedures of the company concerned. 31 October 2024 AN-3 P.10 NOTE: A HKAR-66 Category B2/B2* licence cannot be used for the purposes of a HKAR-66 Category A certification authorisation unless the HKAR-66 Category A licence is also held. 5.3 HKAR-66 Category B2/B2* certification authorisations allow the holder to issue Certificate of Release to Service under HKAR 145.50 for the line maintenance on aircraft which are endorsed as individual types on the licence and the corresponding authorisation. HKAR-66 Category B2/B2* licences to the full HKAR-66 standard include scope to allow the issue of a certification authorisation covering work on a combination of the following aircraft systems: • instruments; • automatic pilots (aeroplanes, helicopters and autoland systems); • radio communication/navigation; • radio radar; • electrical power generation and distribution systems (power distribution in respect of avionic systems) including lighting systems. Scope may not include for authorisation in respect of work on electrical power distribution systems or electrical/avionic components in mechanical systems. (Licences issued on the basis of 'protected rights' may include such scope where so endorsed.) NOTES (1): The HKAR-66 Category B2/B2* licence holder is not entitled to certify for any overhaul work. (2): A category B2* aircraft maintenance licence shall permit the holder to issue Certificate of Release to Service following minor scheduled line maintenance and simple defect rectification within the limits of tasks specifically endorsed on the certification authorisation referred to in HKAR 145.35. This certification privilege shall be restricted to work that the licence holder has personally performed in the maintenance organisation which issued the certification authorisation and limited to the ratings already endorsed in the B2* licence. 5.4 The certification authorisation can only be issued by a HKAR-145 approved maintenance organisation when the licence holder has the appropriate basic HKAR-66 Category B2/B2* listed and the aircraft type rating endorsed on the HKAR-66 Aircraft Maintenance Licence. The type training for a HKAR-66 Category B2/B2* type endorsement, conducted under a HKAR-147 approval, will represent the appropriate technologies as specified in HKAR-66. The certification authorisation will specify the privileges for the individual, giving due regard to the company scope of approval and any associated procedures agreed with the Director-General, and will specify any limitations to the 31 October 2024 AN-3 P.11 authorisation accordingly. NOTE: A HKAR-66 licence issued on the basis of 'protected rights' may contain technical restrictions equivalent to the limitations of any HKAR-AMEL licence or company authorisations previously held. These 'protected rights' under HKAR-66 are a continuation of certification privileges under an existing licence or certification authorisation which allows current personnel to continue working and certifying without the need to re-qualify. The recognition of these privileges is shown by the inclusion of code 999 against that type rating. Authorisations issued by a HKAR-145 approved maintenance organisation should therefore be similarly restricted in scope. It should be noted that conversion to the full HKAR-66 licence standard is optional. 5.5 HKAR-66 Category B2/B2* licences may also be issued with an endorsement allowing the certification, under the provisions of Articles 9 and 11 of the Order, for work outside of a HKAR-145 approved maintenance organisation on aircraft which are not operated for commercial air transport. Such privileges are limited to Hong Kong registered aircraft only. Certification may only be made for those aircraft types which are endorsed individually or as Group Type Ratings on the licence. The privileges of the endorsement will reflect the certification limitations on the licence. 6 HKAR-66 Category B3 Aircraft Maintenance Licence 6.1 A HKAR-66 Category B3 Aircraft Maintenance Licence may be issued to a person who has demonstrated a competence to act in the role of a certifying engineer for maintenance of simple light aeroplanes. The licence, in its own right, does not entitle the holder to exercise any certification privileges in respect of aircraft and will be used in conjunction with a HKAR-145 certification authorisation. NOTE: HKAR-145 does not require a HKAR-66 Category C certifying staff for the certification of simple light aeroplanes as Category B1.2 or B3 covers all maintenance. 6.2 Such authorisations will be issued by a HKAR-145 maintenance organisation appropriately approved by the Director-General. NOTE: A HKAR-66 Category B3 licence cannot be used for the purpose of a HKAR-66 Category A certification authorisation unless the Category A licence is also held. 6.3 HKAR-66 Category B3 certification authorisations allow the holder to issue Certificates of Release to Service under HKAR 145.50 for maintenance on simple light aeroplanes which are endorsed as individual aeroplane types, aeroplane manufacturers group types, aeroplane group types and/or wooden aeroplane group types on the licence and the corresponding authorisation. HKAR-66 Category B3 licences to the full HKAR-66 standard include scope to allow the issue of a certification authorisation covering work on a combination of the following disciplines: • airframe and their related systems; 31 October 2024 AN-3 P.12 • engines and their related systems; • electrical power generation and distribution systems (power distribution in respect of airframe and/or engine systems) including lighting systems; • avionic line replaceable units (LRU). In respect of avionic LRUs, the work is limited to cases where the serviceability of the system can be established by a simple self test facility (BITE) or by using simple test equipment and it is expected that, for reference purposes, a list of such components will be prepared for each aircraft type by the HKAR-145 approved maintenance organisation. (Defect rectification on avionic systems which requires an element of decision making in its application – other than a simple go/no go decision – cannot be certified). NOTE: The HKAR-66 Category B3 licence holder is not entitled to certify for any overhaul work. 6.4 The certification authorisation can only be issued by a HKAR-145 approved maintenance organisation when the licence holder has the appropriate basic HKAR-66 Category listed and the aircraft type rating endorsed on the HKAR-66 Aircraft Maintenance Licence. The type training for a HKAR-66 Category B3 type endorsement, conducted under a HKAR-147 approval, will represent the appropriate technologies as specified in HKAR-66. The certification authorisation will specify the privileges for the individual, giving due regard to the company scope of approval and any associated procedures agreed with the Director-General, and will specify any limitations to the authorization accordingly. NOTE: A HKAR-66 licence issued on the basis of 'protected rights' may contain technical restrictions equivalent to the limitations of any HKAR-AMEL licence or company authorisations previously held. These 'protected rights' under HKAR-66 are a continuation of certification privileges under an existing licence or certification authorisation which allows current personnel to continue working and certifying without the need to re-qualify. Authorisations issued by a HKAR-145 approved maintenance organisation should therefore be similarly restricted in scope. It should be noted that conversion to the full HKAR-66 licence standard is optional. 6.5 HKAR-66 Category B3 licences may also be issued with an endorsement allowing the certification, under the provisions of Articles 9 and 11 of the Order, for work outside of a HKAR-145 approved maintenance organisation on aircraft which are not operated for commercial air transport. Such privileges are limited to Hong Kong registered aircraft only. Certifications may only be made for those aircraft types which are endorsed individually or as Group Type Ratings on the licence. The privileges will reflect the limitations for the relevant licence categories. 31 October 2024 AN-3 P.13 7 HKAR-66 Category C Aircraft Maintenance Licence 7.1 A HKAR-66 Category C Aircraft Maintenance Licence may be issued to a person who has demonstrated a competence to release an aircraft following base maintenance. The privileges apply to the aircraft in its entirety in a HKAR-145 maintenance organisation. The licence, in its own right, does not entitle the holder to exercise any certification privileges in respect of aircraft and will be used in conjunction with a HKAR-145 certification authorisation. NOTE: HKAR-145 does not require a HKAR-66 Category C certifying staff for the certification of simple light aeroplanes as Category B1.2 or B3 covers all maintenance. 7.2 Such authorisations will be issued by a HKAR-145 maintenance organisation appropriately approved by the Director-General. HKAR-66 licence holders will therefore act in accordance with the authorisation procedures of the company concerned. 7.3 HKAR-66 Category C certification authorisations allow the holder to issue Certificate of Release to Service under HKAR 145.50 following the completion of base maintenance on aircraft which are endorsed on the licence and the corresponding authorisation as individual types. Such persons are in essence certifying for the completion of the process associated with base maintenance and are supported by appropriately qualified and experienced HKAR-66 Categories B1 and B2/B2* staff who will inspect and supervise the actual work. The scope of coverage therefore reflects the whole aircraft and is not limited to certification of solely mechanical or avionic systems. 7.4 It should be noted that a HKAR-66 Category C licence holder cannot be authorised to act as a line maintenance certifying engineer, exercising line maintenance certification privileges, nor conducting base maintenance, in the role of an inspector or supervisor clearing individual tasks, unless the licence is also endorsed with the appropriate HKAR-66 Category B1 and/or B2/B2* licence with the relevant type rating endorsements. 7.5 The certification authorisation can only be issued by a HKAR-145 approved maintenance organisation when the HKAR-66 licence holder has the basic Category C listed and the aircraft type rating endorsed on the HKAR-66 Aircraft Maintenance Licence. The type training for a HKAR-66 Category C type endorsement, conducted under a HKAR-147 approval, will represent the appropriate mix of systems knowledge as specified in HKAR-66. The certification authorisation will specify the privileges for the individual, giving due regard to the company scope of approval and any associated procedures agreed with the Director-General. NOTE: A person qualified to HKAR-66 Category B1 or B2/B2* level with type endorsements will also be eligible for a Category C type authorisation, providing the basic HKAR-66 Category C licence is held. 31 October 2024 AN-3 P.14 8 HKAR-66 General Holders of HKAR-66 Aircraft Maintenance Licence with type endorsements may be required to undertake appropriate differences type training where the aircraft type to be authorised embodies significant variations in the equipment fitted or the aircraft systems configuration. The responsibility for determining the training to be undertaken will remain with the HKAR-145 approved maintenance organisation. 9 Cancellation This Notice cancels Airworthiness Notice No. 3 Issue 26, dated 28 June 2019, which should be destroyed.

INTENTIONALLY LEFT BLANK CIVIL AVIATION DEPARTMENT HONG KONG, CHINA Airworthiness Notice No. 5 Issue 3 30 October 2001 TYRE WEAR LIMITATIONS service when it is worn to such an extent that its wet runway performance would be seriously impaired. This may be defined as when: (a) it is worn such that any groove has a depth of less than 2 mm of tread for more 1 Introduction 1.1 Hong Kong Aviation Requirements require that for certification of new types of aircraft, the depth of tyre tread below which wet braking friction characteristics are impaired should be specified at the time of certification; it is also required that it should be possible to determine, in operational conditions, when the tread depth is worn below this limit. 1.2 This Notice provides general guidance on the subject of tyre wear limitations for operators of all public transport aeroplanes of more than 5700 kg Maximum Total Weight Authorised on the Hong Kong Register for which a limiting tyre tread depth is not otherwise available. 2 Discussion 2.1 Accidents and incidents, resulting from both loss of braking friction and loss of directional control on wet runways, continue to occur. While the scheduled accelerate-stop and landing distances provide some allowance for deterioration in friction, it has been established that this allowance is not sufficient to maintain the required level of safety if tyres which are more than 80% worn are used in wet runway operations. 2.2 As it is not possible fully to allow for this by increasing the scheduled distances (because of the frequency of incidents caused by loss of directional control, even on the most favourable wheel arrangements), the Director-General favours the retention of current scheduled distances, together with a recommended minimum tread depth applicable to all aircraft tyres. 3 Recommendation In the absence of evidence of the safety of a lower limit for a particular aircraft/tyre/operation combination, it is recommended that a tyre be withdrawn from AN-5 P.1 30 October 2001 than one quarter of the tread circumference or (b) at any place on the circumference the tread pattern is worn to a depth of less than 2 mm across the whole width of the tread in contact with the runway. NOTE: This is not a rigid definition and equivalence may be provided if, for example, tyre wear is such that whilst one groove is less than 2 mm all the others are 3 mm or more. 4 Cancellation This notice cancels Airworthiness Notice No. 5 Issue 2, dated 1 November 1996, which should be destroyed.
