Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 3 24 April 2025 MCAR-66.A.3 Licence categories and subcategories Aircraft maintenance licences include the following categories and, where applicable, subcategories and system ratings: (a) Category A, divided into the following subcategories: - A1 Aeroplanes Turbine; - A2 Aeroplanes Piston; - A3 Helicopters Turbine; - A4 Helicopters Piston. (b) Category B1, divided into the following subcategories: - B1.1 Aeroplanes Turbine; - B1.2 Aeroplanes Piston; - B1.3 Helicopters Turbine; - B1.4 Helicopters Piston. (c) Category B2 The B2 licence is applicable to all aircraft. (d) Category B2L The B2L licence is applicable to all aircraft other than those in Group 1 as set out in point 66.A.5(1) and is divided into the following ‘system ratings’: - communication/navigation (com/nav), - instruments, - autoflight, - surveillance, - airframe systems. A B2L licence shall contain, as a minimum, one system rating. (e) Category B3 The B3 licence is applicable to piston-engine non-pressurised aeroplanes of 2000kg Maximum Take-off Mass (MTOM) and below. (f) Category L, divided into the following subcategories: - L1C: composite sailplanes, - L1: sailplanes, - L2C: composite powered sailplanes and composite ELA1 aeroplanes, - L2: powered sailplanes and ELA1 aeroplanes, - L3H: hot-air balloons, - L3G: gas balloons, - L4H: hot-air airships, - L4G: ELA2 gas airships, Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 4 24 April 2025 - L5: gas airships other than ELA2. (g) Category C The C licence is applicable to aeroplanes and helicopters. GM 66.A.3 Licence categories ‘ELA1 aeroplanes’ refers to those aeroplanes which meet the definition of ‘ELA1 aircraft’ ‘ELA2 gas airships’ refers to those gas airships which meet the definition of ‘ELA2 aircraft’. ‘Gas airships other than ELA2’ refers to those gas airships which do not meet at least one condition of the definition of ‘ELA2 aircraft’. NOTE: The ‘ELA2 aircraft’ category includes all ‘ELA1 aircraft’. The term ‘powered sailplane’ includes: - those powered sailplanes which may take off solely by means of their own power (self- launching sailplanes); and - self-sustaining powered sailplanes; and - touring motor gliders (TMGs). While the L1C subcategory only includes composite sailplanes, the L1 subcategory includes all sailplanes (composite, metal and wood). While the L2C subcategory only includes composite powered sailplanes and composite ELA1 aeroplanes, the L2 subcategory includes all powered sailplanes and ELA1 aeroplanes (composite, metal and wood). In the case of maintenance of mixed balloons (combination of gas and hot air), it is required to hold both L3G and L3H subcategories. For the B2L licence, a ‘system rating’ is a rating which gives privileges to release maintenance on the aircraft systems covered by the ‘system rating’ and electrical systems. The sentence ‘shall contain, as a minimum, one system rating’ refers to the fact that the application for a B2L licence should be made for any of the system ratings or any combination of the system ratings specified in 66.A.3. There is no specific order in which the system ratings should be applied for. Any combination of system ratings is possible. Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 5 24 April 2025 The description of systems covered by the different system ratings is provided in Appendix I ‘Basic Knowledge Requirements’ under paragraph ‘2. Modularisation’, subparagraph related to ‘Categories B2 and B2L’. Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 6 24 April 2025 MCAR-66.A.5 Aircraft groups For the purpose of ratings on aircraft maintenance licences, aircraft shall be classified into the following groups: (1) Group 1: complex motor-powered aircraft; multi-engine helicopters; other than piston- engine aeroplanes, with maximum certified operating altitude exceeding FL290; aircraft equipped with fly-by-wire systems; gas airships other than ELA2. The CAA may decide to classify into Group 2, Group 3 or Group 4, as appropriate, an aircraft which meets the conditions set out in the first subparagraph, if it considers that the lower complexity of the particular aircraft justifies so. (2) Group 2: aircraft other than those in Group 1 belonging to the following subgroups: (i) subgroup 2a: - single turboprop engine aeroplanes, - those turbine-engine aeroplanes classified by the CAA in this subgroup because of their lower complexity. (ii) subgroup 2b: - single turbine engine helicopters, - those multiple turbine engine helicopters classified by the CAA in this subgroup because of their lower complexity. (iii) subgroup 2c: - single piston engine helicopters, - those multiple piston engine helicopters classified by the CAA in this subgroup because of their lower complexity. (3) Group 3: piston engine aeroplanes other than those in Group 1. (4) Group 4: sailplanes, powered sailplanes, balloons and airships, other than those in Group 1.

(b) (Reserved) (c) In addition to the documents required in points 66.A.10(a) and 66.B.105, as appropriate, the applicant for additional basic categories or subcategories to an aircraft maintenance licence shall submit his/her current original aircraft maintenance licence to the CAA together with CAA Form 19 (d) (Reserved) (e) (Reserved) (f) Each application shall be supported by documentation to demonstrate compliance with the applicable theoretical knowledge, practical training and experience requirements at the time of application. Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 9 24 April 2025 AMC 66.A.10 Application 1. Maintenance experience should be written up in a manner that the reader has a reasonable understanding of where, when and what maintenance constitutes the experience. A task by task account is not necessary but at the same time a bland statement “X years maintenance experience completed” is not acceptable. A log book of maintenance experience is desirable and the CAA may require such log books to be kept. It is acceptable to cross refer in CAA Form 19 to other documents containing information on maintenance. 2. Applicants claiming the maximum reduction in 66.A.30(a) total experience based upon having successfully completed 147.A.200 approved basic training, should include the MCAR- 147 certificate of recognition for approved basic training. 3. Applicants claiming reduction in MCAR-66.A.30(a) total experience based upon having successfully completed technical training in an organisation or institute recognised by the CAA as a competent organisation or institute, should include the relevant certificate of successful completion of training. GM 66.A.10(a) Application When an application is made for a licence in the B2L category, the applicant should specify on the CAA Form 19: − the system rating or the combination of system ratings the applicant applies for; and − the aircraft rating, considering that according to 66.A.45(e), a B2L licence endorsed with full subgroup 2b can be endorsed also with full subgroup 2c. When applying for the addition of a system rating on a B2L licence, the applicant should provide together with the application, the demonstration of compliance with the experience requirements related to the system the applicant applies for. When a B2L licence holder applies for the extension of a B2L licence to add a new system rating, he/she needs to demonstrate the practical experience required by 66.A.30(a)(2a) for the system rating but also the practical experience required by 66.A.45(e) and (f) in case the aircraft group is different. When a B2L licence holder applies for the change of his/her B2L licence to the B2 category, he/she needs only to: − demonstrate by examination the differences between the basic knowledge corresponding to the B2L licence held and the basic knowledge of the B2 licence, as described in Appendix I; and − demonstrate the additional experience described in Appendix IV. These requirements can be found also in 66.B.110. When an applicant applies for the extension of his/her B2L licence to a B2 licence and he/she meets the relevant requirements, the B2L licence is replaced by the B2 licence. Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 10 24 April 2025 MCAR-66.A.15 Eligibility An applicant for an aircraft maintenance licence shall be at least 18 years of age.

(b) The holder of an aircraft maintenance licence may not exercise its privileges unless: 1. in compliance with the applicable requirements of MCAR-M, MCAR-145, MCAR-ML and MCAR-CAO; and Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 12 24 April 2025 2. in the preceding two-year period he/she has, either had six months of maintenance experience in accordance with the privileges granted by the aircraft maintenance licence or, met the provision for the issue of the appropriate privileges; and 3. he/she has the adequate competence to certify maintenance on the corresponding aircraft; and 4. he/she is able to read, write and communicate to an understandable level in the language(s) in which the technical documentation and procedures necessary to support the issue of the certificate of release are written. Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 13 24 April 2025 GM 66.A.20(a) Privileges 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 which 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 avionics 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 license holder. Simple test means a test described in approved maintenance data and meeting all the following criteria: - 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 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 14 24 April 2025 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 maintenance: 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 2000 Kg MTOM and below, 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 point 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 licence 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, B2, 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 and L qualifications may perform both roles in base maintenance. AMC 66.A.20(a)(4) Privileges ‘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. 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, Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 15 24 April 2025 he/she should apply for the rating ‘airframe system’ on the B2L 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. Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 16 24 April 2025 AMC 66.A.20(b)2 Privileges The 6 months maintenance experience in 2 years 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 organization: - 6 months working with the same organisation; or - 6 months split up into different blocks, working within the same or in different organisations. The 6 months 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 MCAR-M.A.801(b)1 or as a combination thereof. When certifying staff maintains and releases aircraft in accordance with MCAR-M.A.801(b)1, in certain circumstances this number of days may even be reduced by 50% when agreed in advance by the CAA. These circumstances consider the cases where the holder of a MCAR- 66 licence happens to be the owner of an aircraft and carries out maintenance on his own aircraft, or where a licence holder maintains an aircraft operated for low utilization, 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 should be spread over the intended 6 months 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; - Troubleshooting; - Repairing; - Modifying; - Changing component; - Supervising these activities; - 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 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 17 24 April 2025 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 authorization the experience should be on that particular aircraft or on a similar aircraft within the same licence (sub)category. Two aircraft can be considered as 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 or turboprop or turbofan or turboshaft or jet-engine or push propellers); and - Flight control systems (only mechanical controls or hydromechanically powered controls or electromechanically powered controls); and - Avionic systems (analogue systems or digital systems); and - Structure (manufactured of metal or composite or wood). For licences endorsed with (sub)group ratings: - In the case of B1 licence endorsed with group (sub)group ratings (either manufacturer sub-group or full (sub)group) as defined in MCAR-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 MCAR-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 rating “piston-engine non-pressurized 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 or 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: Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 18 24 April 2025 - Date; - Aircraft type; - Aircraft identification i.e. registration; - ATA chapter (optional); - Operation performed i.e. 100 FH check, MLG wheel change, engine oil check and complement, SB embodiment, troubleshooting, structural repair, STC embodiment, etc; - In the particular case of MCAR-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 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 19 24 April 2025 GM 66.A.20(b)2 Privileges 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 training). 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. Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 20 24 April 2025 AMC 66.A.20(b)3 Privileges 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 essential 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 MCAR-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 MCAR-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- 600/700/800, 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. - 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 MCAR-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 MCAR-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).

(f) Experience shall have been acquired within the ten years preceding the application for an aircraft maintenance licence or the addition of a category or subcategory to such a licence. Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 28 24 April 2025 AMC1 66.A.30(a) Basic experience requirements 1. 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 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 (MCAR-145, M.A. Subpart F, MCAR-CAO, FAR-145, etc) or under the supervision of independent certifying staff; - May be combined with MCAR-147 approved training (or other training approved by the CAA) 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 professional or on a voluntary basis; - 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 CAA, 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 a sufficient experience for each category/subcategory during the required period. Examples: - Application for a B1.1 (turbine aeroplanes) + B1.3 (turbine helicopters): The 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. Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 29 24 April 2025 - 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 every week on aeroplanes and a few days every week on helicopters). - Application for a B1.1 (turbine aeroplanes) + B2 (avionics): The 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: The 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 engineering 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 organisation that is approved in accordance with MCAR-145, MCAR-CAO, MCAR-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 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 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 30 24 April 2025 than CMPA, then only the corresponding category C licence with respect to other than CMPA 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 base 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 encouraged 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 Maldivian civil regulatory framework, at least 1 year should be in a MCAR-145 or MCAR- CAO environment, including participation in the performance of base maintenance tasks for 6 months Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 31 24 April 2025 GM1 66.A.30(a) Basic experience requirements The table below summarises the basic experience requirements for the category C licence.

When a person already holds a type rating on the licence and such type rating is amended in the Appendix I to AMC to MCAR-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 additional 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, MCAR- 145.A.35(a) and MCAR-M.A.607(a), and MCAR-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 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 (sub)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; Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 41 24 April 2025 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 certifying 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. Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 42 24 April 2025 AMC 66.A.45(e) Endorsement with aircraft ratings 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 that 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 MCAR-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. Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 43 24 April 2025 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. Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 44 24 April 2025 GM1 66.A.45(h)(ii) Endorsement with aircraft ratings For subcategories L1 and L2, it is possible to endorse the corresponding ratings with limitations depending on the type of structures covered by the experience gained. For subcategory L3G, it is possible to endorse the rating ‘gas balloons’ with a limitation to ‘other than ELA1 gas balloons’ if the experience gained only covers ELA1 gas balloons. However, the limitations referred to in 66.A.45(h)(ii) do not apply for subcategories L1C, L2C, L3H, L4H and L4G. The ratings on these licences can only be obtained after demonstration of the appropriate experience representative of the full scope of the licence subcategory. Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 45 24 April 2025 MCAR-66.A.50 Limitations (a) Limitations introduced on an aircraft maintenance licence are exclusions from the certification privileges and, in the case of limitations referred to in point 66.A.45, they affect the aircraft in its entirety. (b) For limitations referred to in point 66.A.45, limitations shall be removed upon: 1. demonstration of appropriate experience, or 2. after a satisfactory practical assessment performed by the CAA. (c) For limitations referred to in point 66.A.70, limitations shall be removed upon satisfactory completion of examination on those modules/subjects defined in the applicable conversion report. Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 46 24 April 2025 AMC 66.A.50(b) Limitations 1. The appropriate experience required to remove the limitations referred 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 be 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 on just one aircraft type, provided this type is representative of the (sub)group in relation to the limitation being removed. 3. (Reserved) 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. Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 47 24 April 2025 MCAR-66.A.55 Evidence of qualification 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. MCAR-66.A.70 Conversion Provisions (a) The holder of a valid certifying staff qualification issued by the CAA, prior to the date of entry into force of MCAR-66 shall be issued an aircraft maintenance licence without further examinations subject to conditions specified in Section B Subpart D. (b) A person undergoing a certifying staff qualification process approved by the CAA, prior to the date of entry into force of MCAR-66 may continue to be qualified. The holder of a certifying staff qualification gained following such qualification process shall be issued an aircraft maintenance licence without further examination subject to the conditions specified in the applicable conversion report. (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 Maldives before the entry into force of MCAR-66 and ii. the basic knowledge requirements and the basic examination standards laid down in Appendix I and II to MCAR-66. (d) By derogation from point (c), for aircraft not used by licenced air carriers in accordance with MCAR-Air Operations, other than complex motor-powered aircraft, and for balloons, sailplanes, motor-powered sailplanes and airships, the aircraft maintenance licence shall contain limitations in accordance with MCAR-66.A.50 to ensure that the certifying staff privileges valid in the Maldives before the entry into force of the applicable MCAR-66 licence category/subcategory and those of the converted MCAR-66 aircraft maintenance licence remain the same. Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 48 24 April 2025 GM 66.A.70 Conversion provisions 1. As described in point 66.A.70, the conversion provisions apply to the holder of a valid certifying staff qualification issued by the CAA prior to the date of entry into force of MCAR- 66. The sentence “the holder of a valid certifying staff qualification issued by the CAA” means any person who had a qualification issued by the CAA allowing that person the performance of activities identical to the privileges of “certifying staff” contained in MCAR-66. 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. 2. The conversion applies to “certifying staff qualifications” such as , for example: − holding a Maldivian licence (or completed the process to obtain such a licence); − having completed a qualification process defined by the CAA; − 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 limited 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 MCAR-66”, which means those qualifications valid before 15 July 2007. 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 licences are those valid before the Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 49 24 April 2025 date where the CAA has the obligation to start issuing such licences, which means the following: − for the B3 licence, those qualifications valid before 31 December 2015; − for the B2L licence, those qualifications valid before 31 August 2021; − for the L licence, those qualifications valid before 31 August 2021. 4. (Reserved). 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 to a B1.2 licence with limitations linked to some missing elements of the MCAR-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 MCAR-66 Appendix I and II standard, introducing only those limitations required in order to maintain the existing privileges. GM 66.A.70(c) Conversion provisions For example, a limitation could be where a person holds a pre-existing certifying staff qualification which covered, to the standard of MCAR-66 Appendix I and II, all the modules/subjects corresponding to the B1 licence except for electrical power systems. This person would be issued an MCAR-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 For aircraft not used by air carriers licensed in accordance with MCAR-Air Operations other than complex motor-powered aircraft, an example of limitations could be where a person holds a pre-MCAR-66 qualification which covered privileges to release work performed on aircraft structures, powerplant, mechanical and electrical systems but excluded privileges on aircraft equipped with turbine engine, aircraft above 2 000 kg MTOM, pressurised aircraft and aircraft equipped with retractable landing gear. This person would be issued with a MCAR-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 MCAR- Air Operations (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-MCAR-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 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements Issue: 4.00 50 24 April 2025 aircraft type (for example, a Cessna 172). This pilot-owner would receive a MCAR-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 MCAR-Air Operations (this limitation always exists); − aircraft other than a Cessna 172; − aircraft not owned by the licence holder. One more example would be the case where a person holds a pre-MCAR-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 MCAR-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-MCAR-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 MCAR-66 aircraft maintenance licence in the L1C subcategory, with the following limitations: − complex maintenance tasks described in Appendix VII to MCAR-M, standard changes described in MCAR-21.A.90B, and standard repairs described in MCAR-21.A.431B. The essential aspect is that the limitations are established in order to maintain the privileges of the MCAR-66 qualification without comparing the previous qualification with the standard of MCAR-66 Appendix I and II. For removal of limitations, refer to MCAR-66.A.50(c).
