ANO(AW)Part-66 Aircraft Maintenance Licence Chapter 1: Regulations & Acceptable Means of Compliance (Section A) Issue-2, May 2016 Civil Aviation Authority, Bangladesh 1-6 NOTE: Instruments are formally included in the privileges of the B2 licence holders. However, maintenance on electromechanical and pitot-static components may also be released by a B1 license holder. Simple test means a test described in approved maintenance data and meeting all the following criteria: x 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. x 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. x 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. Trouble shooting means the procedures and actions necessary to identify the root cause of a defect or malfunction using approved maintenance data. It may include the use of BITE or external test equipment. Line maintenance means any maintenance that is carried out before flight to ensure that the aircraft is fit for the intended flight. It may include: x trouble shooting; x defect rectification; x component replacement with the use of external test equipment, if required. Component replacement may include components such as engines and propellers; x scheduled maintenance and/or checks including visual inspections that will detect obvious unsatisfactory conditions/discrepancies but do not require extensive in-depth inspection.

The CAAB will prescribe the conditions under which these tasks may be performed. Base Maintenance means any task falling outside the criteria are given above for Line Maintenance. NOTE: Aircraft maintained in accordance with “progressive” type programmes need to be individually assessed in relation to this paragraph. In principle, the decision to allow some “progressive” checks to be carried out is determined by the assessment that all tasks within the particular check can be carried out safely to the required standards at the designated line maintenance station. ANO(AW)Part-66 Aircraft Maintenance Licence Chapter 1: Regulations & Acceptable Means of Compliance (Section A) Issue-2, May 2016 Civil Aviation Authority, Bangladesh 1-7 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 category C licence permits certification of scheduled 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 and B3 support staffs, as appropriate, have signed for the maintenance tasks under their respective specialisation. The principal function of the category C certifying staff is to ensure that all required maintenance has been called up and signed off by the category B1, B2 and B3 support staff, as appropriate, before issue of the certificate of release to service. Only category C personnel who also hold category B1, B2 or B3 qualifications may perform both roles in base maintenance. 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 continuous employment within the same organisation; or - 6 months split up into different blocks, employed 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 ANO Part or the corresponding regulation issued by CAAB or as a combination hereof. When certifying staff maintains and releases aircraft in accordance with Part M.801(b)2, in certain circumstances this number of days may even be reduced by 50% when agreed in advance by CAAB. These circumstances consider the cases where the holder of a Part-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; ANO(AW)Part-66 Aircraft Maintenance Licence Chapter 1: Regulations & Acceptable Means of Compliance (Section A) Issue-2, May 2016 Civil Aviation Authority, Bangladesh 1-8 - Trouble-shooting; - Repairing; - Modifying; - Changing component; - Supervising these activities; - Releasing aircraft to service. For category A certifying staff, 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 145.30(g), including servicing, component changes and simple defect rectifications. For category B1 and B2, for every aircraft included in the authorization the experience should be on that particular aircraft or on a similar aircraft within the same licence subcategory. 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): (a) Propulsion systems (piston or turboprop or turbofan or turbo-shaft or jet-engine or push propellers); and (b) Flight control systems (only mechanical controls or hydro-mechanically powered controls or electro-mechanically powered controls); and (c) Avionic systems (analog systems or digital systems); and (d) Structure (manufactured of metal or composite or wood). For licences endorsed with (sub) group ratings: - In the case of B1 licence endorsed with group ratings (either manufacturer group or full group) as defined in Part-66.A.45(g) the holder may show experience on at least one aircraft type per group and per aircraft structure (metal, composite, wood). - In the case of a B2 licence endorsed with group ratings (either manufacturer group or full group) as defined in Part-66.A.45(g) the holder may show experience on at least one aircraft type per group. - In the case of a B3 licence endorsed with the rating “piston-engine non-pressurized aeroplanes of 2000kg MTOM and below” as defined in 66.A.45, the holder should show experience on at least one aircraft type per aircraft structure (metal, composite, wooden). For category C, the experience should cover at least one of the aircraft types endorsed on the authorization. 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. ANO(AW)Part-66 Aircraft Maintenance Licence Chapter 1: Regulations & Acceptable Means of Compliance (Section A) Issue-2, May 2016 Civil Aviation Authority, Bangladesh 1-9 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: (a) Date; (b) Aircraft type; (c) Aircraft identification i.e. registration; (d) ATA chapter (optional); (e) Operation performed i.e. 100 FH check, MLG wheel change, engine oil check and complement, SB embodiment, troubleshooting, structural repair, STC embodiment; (f) Type of maintenance i.e. base, line; (g) Type of activity i.e. perform, supervise, release; (h) Category used A, B1, B2, B3 or C. (i) Duration in days or partial-days. 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. 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: x 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 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 covering only the Airbus 320 (CFM56). x 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- 600/700/800, without performing any difference training for the 737-900. x 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. ANO(AW)Part-66 Aircraft Maintenance Licence Chapter 1: Regulations & Acceptable Means of Compliance (Section A) Issue-2, May 2016 Civil Aviation Authority, Bangladesh 1-10 x Specific technology and options selected by each customer which may not have been covered by the type training. x Changes in the basic knowledge requirements of Appendix I to Part-66 not requiring re- examination of existing licence holders (grandfathered privileges). x 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. x 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. x 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 1. Holders of a Part-66 aircraft maintenance licence may not exercise certification privileges unless they have a general knowledge of the language used within the maintenance environment including knowledge of common aeronautical terms in the language. The level of knowledge should be such that the licence holder is able to: - read and understand the instructions and technical manuals in use within the organisation; - make written technical entries and any maintenance documentation entries, which can be understood by those with whom they are normally required to communicate; - read and understand the maintenance organisation procedures; - communicate at such a level as to prevent any misunderstanding when exercising certification privileges. 2. In all cases, the level of understanding should be compatible with the level of certification privileges exercised. 66.A.25 Basic knowledge requirements (a) An applicant for an aircraft maintenance licence or the addition of a category or subcategory to such an aircraft maintenance licence shall demonstrate, by examination, a level of knowledge in the appropriate subject modules in accordance with Appendix I to this Part. The examinations shall be conducted either by a training organisation appropriately approved in accordance with under Part 147 or by CAAB. (b) The training courses and examinations shall be passed within ten years prior to the application for an aircraft maintenance licence or the addition of a category or subcategory to such aircraft maintenance licence.

(b) The holder of an aircraft maintenance licence shall complete the relevant parts of the CAAB Form 19 (See Appendix V) and submit it with the holder’s copy of the licence to CAAB, unless the holder works in a maintenance organisation approved in accordance with Part-145 that has a procedure in its exposition whereby such organisation may submit the necessary documentation on behalf of the aircraft maintenance licence holder. (c) Any certification privilege based upon an aircraft maintenance licence becomes invalid as soon as the aircraft maintenance licence is invalid. ANO(AW)Part-66 Aircraft Maintenance Licence Chapter 1: Regulations & Acceptable Means of Compliance (Section A) Issue-2, May 2016 Civil Aviation Authority, Bangladesh 1-14 (d) The aircraft maintenance licence is only valid (i) when issued and/or changed by CAAB and (ii) when the holder has signed the document. GM 66.A.40 Continued validity of the aircraft maintenance licence Validity of the Part-66 aircraft maintenance licence is not affected by recency of maintenance experience whereas the validity of the 66.A.20 privileges is affected by maintenance experience as specified in 66.A.20(a) 66.A.45 Endorsement with aircraft ratings (a) In order to be entitled to exercise certification privileges on a specific aircraft type, the holder of an aircraft maintenance licence needs to have his/her licence endorsed with the relevant aircraft ratings. - For category B1, B2 or C the relevant aircraft ratings are the following: 1. For group 1 aircraft, the appropriate aircraft type rating. 2. For group 2 aircraft, the appropriate aircraft type rating, manufacturer sub-group rating or full sub-group rating. 3. For group 3 aircraft, the appropriate aircraft type rating or full group rating. - For category B3, the relevant rating is “piston-engine non-pressurized aeroplanes of 2000 Kg MTOM and below”. - For category A, no rating is required, subject to compliance with the requirements of point 145.A.35 of Part-145. (b) The endorsement of aircraft type ratings requires the satisfactory completion of the relevant category B1, B2 or C aircraft type training. (c) In addition to the requirement of point (b), the endorsement of the first aircraft type rating within a given category/sub-category requires satisfactory completion of the corresponding On-the-Job Training, as described in Appendix III to Part-66. (d) By derogation from points (b) and (c), for group 2 and 3 aircraft, aircraft type ratings may also be granted after: - Satisfactory completion of the relevant category B1, B2 or C aircraft type examination described in Appendix III to this Part-66, and - In the case of B1 and B2 category, demonstration of practical experience on the aircraft type. In that case, the practical experience shall include a representative cross section of maintenance activities relevant to the licence category. In the case of a category C rating for a person qualified by holding an academic degree as specified in point 66.A.30(a)(5), the first relevant aircraft type examination shall be at the category B1 or B2 level. (e) For group 2 aircraft: 1. The endorsement of manufacturer sub-group ratings for category B1 and C licence holders requires complying with the aircraft type rating requirements of at least two aircraft types from the same manufacturer which combined are representative of the applicable manufacturer sub-group; ANO(AW)Part-66 Aircraft Maintenance Licence Chapter 1: Regulations & Acceptable Means of Compliance (Section A) Issue-2, May 2016 Civil Aviation Authority, Bangladesh 1-15 2. The endorsement of full sub-group ratings for category B1 and C licence holders requires complying with the aircraft type rating requirements of at least three aircraft types from different manufacturers which combined are representative of the applicable sub-group; 3. The endorsement of manufacturer sub-groups and full sub-group ratings for category B2 licence holders requires demonstration of practical experience which shall include a representative cross section of maintenance activities relevant to the licence category and to the applicable aircraft sub-group. (f) For group 3 aircraft: 1. The endorsement of the full group 3 rating for category B1, B2 and C licence holders requires demonstration of practical experience, which shall include a representative cross section of maintenance activities relevant to the licence category and to the group 3. 2. For category B1, unless the applicant provides evidence of appropriate experience, the group 3 rating shall be subject to the following limitations, which shall be endorsed on the licence: - Pressurized aeroplanes - Metal structure aeroplanes - Composite structure aeroplanes - Wooden structure aeroplanes - Aeroplanes with metal tubing structure covered with fabric. (g) For the B3 licence: 1. The endorsement of the rating “piston-engine non-pressurized aeroplanes of 2000 Kg MTOM and below” requires demonstration of practical experience, which shall include a representative cross-section of maintenance activities relevant to the licence category. 2. Unless the applicant provides evidence of appropriate experience, the rating referred to in point 1 shall be subject to the following limitations, which shall be endorsed on the licence: - Wooden structure aeroplanes - Aeroplanes with metal tubing structure covered with fabric - Metal structure aeroplanes - Composite structure aeroplanes. GM 66.A.45(b) Endorsement with aircraft ratings 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 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, 145.A.35(a) and M.A.607(a), as applicable, before he/she exercises certification privileges. ANO(AW)Part-66 Aircraft Maintenance Licence Chapter 1: Regulations & Acceptable Means of Compliance (Section A) Issue-2, May 2016 Civil Aviation Authority, Bangladesh 1-16 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(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 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. ANO(AW)Part-66 Aircraft Maintenance Licence Chapter 1: Regulations & Acceptable Means of Compliance (Section A) Issue-2, May 2016 Civil Aviation Authority, Bangladesh 1-17 • 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. AMC 66.A.45(d), (e)3, (f)1 and (g)1 Endorsement with aircraft ratings 1. The “practical experience” should cover a representative cross section including at least 50% of tasks contained in Appendix II to AMC relevant to the licence category and to the applicable aircraft type ratings or aircraft (sub)group ratings being endorsed. 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. GM 66.A.45 Endorsement with aircraft ratings The following table shows a summary of the aircraft rating requirements contained in 66.A.45, 66.A.50 and Appendix III to Part-66. The table contains the following: • The different aircraft groups. • For each licence (sub)category, which ratings are possible (at the choice of the applicant): - Individual type ratings. - Full and/or Manufacturer (sub)group ratings • For each rating option, which are the qualification options. • For the B1.2 licence (Group 3 aircraft) and for the B3 licence (piston-engine non-pressurized aeroplanes of 2000 Kg MTOM and below), which are the possible limitations to be included in the licence if not sufficient experience can be demonstrated in those areas. Note: OJT means “On-the-Job Training” (Appendix III to Part-66, Section 6) and is only required for the first aircraft rating in the licence (sub)category.

(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 CAAB . (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 referred to in point 66.B.300. AMC 66.A.50(b) Limitations 1. The appropriate experience required to remove the limitations referred in 66.A.45(f) and (g) 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 CAAB , 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 may be 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. 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 Personnel exercising certification privileges as well as support staff shall produce their licence, as evidence of qualification, if requested by an authorised person, within 24 hours. 66.A.70 Conversion provisions (a) The holder of a valid certifying staff qualification issued by CAAB , prior to the date of entry into force of this Part shall be issued an aircraft maintenance licence by CAAB without further examination subject to the conditions specified in Section B Subpart D. (b) A person undergoing a certifying staff qualification process valid in Bangladesh, prior to the date of entry into force of this Part may continue to be qualified. The holder of a certifying staff qualification gained following such qualification process shall be issued an aircraft maintenance licence by CAAB without further examination subject to the conditions specified in Section B Subpart D . (c) Where necessary, the aircraft maintenance licence shall contain technical limitations in accordance with point 66.A.50 to reflect the differences between (i) the scope of the certifying staff qualification valid in Bangladesh before the entry into force of this Regulation and (ii) the basic knowledge requirements and the basic examination standards laid down in Appendix I and II to this Part-66. ANO(AW)Part-66 Aircraft Maintenance Licence Chapter 1: Regulations & Acceptable Means of Compliance (Section A) Issue-2, May 2016 Civil Aviation Authority, Bangladesh 1-20 (d) By derogation to paragraph (c) for aircraft not involved in commercial air transport other than large aircraft, the aircraft maintenance licence shall contain limitations in accordance with point 66.A.50 to ensure that the certifying staff privileges valid in Bangladesh before the entry into force of this Regulation and the privileges of the converted Part-66 aircraft maintenance licence remain the same. GM 66.A.70 Conversion provisions 1. As described in point 66.A.70, the conversion provisions apply to the holder of a certifying staff qualification valid in Bangladesh prior to the date of entry into force of Part-66. The sentence “the holder of a certifying staff qualification valid in Bangladesh” means any person who had a qualification valid in that State allowing that person the performance of activities identical to the privileges of “certifying staff”. 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). This is an activity which is performed at very specific points of time and not after every maintenance activity. Since an airworthiness review 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 CAAB 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 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. Reserved 4. Reserved ANO(AW)Part-66 Aircraft Maintenance Licence Chapter 1: Regulations & Acceptable Means of Compliance (Section A) Issue-2, May 2016 Civil Aviation Authority, Bangladesh 1-21 5. A certifying staff qualification can be subject to more than one conversion process and can also be converted to more than one licence (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 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 licence on the basis of 66.A.70(d), which would mean no need to compare with the Part-66 Appendix I and II standard, introducing only those limitations required in order to maintain the existing privileges. GM66.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 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. Other limitations may be necessary after comparison between the ANO(AW) Part-D syllabus and the ANO(AW) Part 66 syllabus. For removal of limitations, refer to 66.A.50(c). GM 66.A.70(d) Conversion provisions In the case of aircraft not involved in commercial air transport other than large 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 turbine engine, aircraft above 2000 Kg MTOM, pressurized aircraft and aircraft equipped with retractable landing gear. This person would be issued a Part-66 aircraft maintenance licence in the B1.2 or B3 (sub)category with the following limitations (exclusions): • Aircraft involved in commercial air transport (this limitation always exists); • Aircraft above 2000 Kg MTOM; • Pressurized 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 his/her 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 involved in commercial air transport (this limitation always exists); • Aircraft other than a Cessna 172; • Aircraft not owned by the licence holder. 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).

(f) Compliance with the practical elements shall be demonstrated (i) by the provision of detailed practical training records or a logbook provided by a ANO(AW) Part-66 Aircraft Maintenance Licence Chapter 2: Procedures for CAA & Acceptable Means of Compliance (Section B) Issue-2, May 2016 Civil Aviation Authority, Bangladesh 2-6 maintenance organisation appropriately approved in accordance with Part-145 or, where available. (ii) by a training certificate covering the practical training element issued by a maintenance training organisation appropriately approved in accordance with Part-147. (g) Aircraft type endorsement shall use the aircraft type ratings specified by CAAB. AMC 66.B.115 Procedure for the change of an aircraft maintenance licence to include an aircraft rating or to remove limitations (a) Where the type training has not been conducted by a Part-147 organisation, there should be supporting documents confirming to CAAB that: • The type training has been approved by CAAB in accordance with 66.B.130, • The applicant has completed the elements of the approved type training; and • The trainee has been successfully examined/assessed. (b) Aircraft type training may be subdivided in airframe and/or powerplant and/or avionics/electrical systems type training courses. 1. Airframe type training course means a type training course including all relevant aircraft structure and electrical and mechanical systems excluding the powerplant. 2. Powerplant type training course means a type training course on the bare engine, including the build-up to a quick engine change unit. 3. 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 large variety of aircraft that can have the same engine type installed. 4. Avionics/electrical systems type training course means type training on avionics and electrical systems covered by but not necessarily limited to ATA Chapters 22, 23, 24, 25, 27, 31, 33, 34, 42, 44, 45, 46, 73 and 77 or equivalent. (c) For the acceptance of the OJT programme described in Section 6 of Appendix III to Part-66, CAAB should develop adequate procedures which may be similar to the procedure described in AMC 66.B.130 for the “direct approval of aircraft type training”. AMC 66.B.100 to 115 Aircraft type endorsement should use the standard codes contained in Appendix I to the AMCs. 66.B.120 Procedure for the renewal of an aircraft maintenance licence validity (a) CAAB shall compare the holder’s aircraft maintenance licence with CAAB records and verify any pending revocation, suspension or change action pursuant to point 66.B.500. If the documents are identical and no action is pending pursuant to point 66. B.500, the holder’s copy shall be renewed for the duration of one year and the file endorsed accordingly. ANO(AW) Part-66 Aircraft Maintenance Licence Chapter 2: Procedures for CAA & Acceptable Means of Compliance (Section B) Issue-2, May 2016 Civil Aviation Authority, Bangladesh 2-7 (b) If the CAAB records are different from the aircraft maintenance licence held by the licence holder: 1. CAAB shall investigate the reasons for such differences and may choose not to renew the aircraft maintenance licence; 2. CAAB shall inform the licence holder and any known maintenance organisation approved in accordance with Part-M Subpart F or Part-145 that may be directly affected of such fact. 3. CAAB, if necessary, take action in accordance with point 66.B.500 to revoke, suspend or change the licence in question. AMC 66.B.120 Procedure for the renewal of an aircraft maintenance licence validity CAAB should not carry out any investigation to ensure that the licence holder is in current maintenance practice as this is not a condition for the renewal of a licence. Ensuring the continued validity of the certification privileges is a matter for the approved Part-145 / Subpart-F maintenance organization or the certifying staff in accordance with M.A.801(b)2. For the purpose of ensuring the continued validity of the certification privileges CAAB may, when periodically reviewing the organizations in accordance with 145.B.30 or M.B.604, or during on-the-spot checks, request the licence holder to provide documentary evidence of compliance with 66.A.20(b) when exercising certification privileges. 66.B.125 Procedure for the conversion of licences including group ratings (a) Individual aircraft type ratings already endorsed on the aircraft maintenance licence shall remain on the licence and shall not be converted to new ratings unless the licence holder fully meets the requirements for endorsement defined in point 66.A.45 of this Annex (Part-66) for the corresponding group/sub-group ratings. (b) The conversion shall be performed in accordance with the following conversion table: 1.

In such case CAAB shall have a procedure to ensure the aircraft type training complies with Appendix III of this Part. AMC 66.B.130 Procedure for the direct approval of aircraft type training 1. The procedure for the direct approval of type training courses by CAAB should require that the following aspects are described by the organisation providing the training: x The content and the duration of the theoretical and/or practical elements, as applicable, in accordance with Appendix III to Part-66, including the Training Need Analysis (TNA); • The teaching methods and instructional equipment; • The material and documentation provided to the student; • The qualification of instructors, examiners and/or assessors, as applicable; • The examination and/or assessment procedure, as applicable. Further guidance about the assessment and the designated assessors is given in Appendix III to AMC to Part- 66. • The documentation and records to be provided to the student to justify the satisfactory completion of the training course and related examination/assessment. This should include not only a certificate of completion but enough documentation and records to justify that the content and duration approved has been met and that the examination/assessment has been successfully passed. 2. The above criteria apply to a full course as well as to a partial course such as the practical element of a type training course and its assessment. 3. The procedure should also indicate how CAAB is going to audit the proper performance of the approved course. 4. The direct approval of aircraft type training should be done on a case by case basis and should not be granted for long term periods, since it is not a privilege of the organisation providing the training. ANO(AW) Part-66 Aircraft Maintenance Licence Chapter 2: Procedures for CAA & Acceptable Means of Compliance (Section B) Issue-2, May 2016 Civil Aviation Authority, Bangladesh 2-10 SUBPART C EXAMINATIONS This Subpart provides the procedure for examinations conducted by CAAB . 66.B.200 Examination by CAAB (a) All examination questions shall be kept in a secure manner prior to an examination, to ensure that candidates will not know which particular questions will form the basis of the examination. CAAB shall nominate those persons who control the questions to be used for each examination. (b) CAAB shall nominate: 1. Persons who control the questions to be used for each examination. 2. Examiners who shall be present during all examinations to ensure the integrity of the examination. (c) Basic examinations shall follow the standard specified in Appendix I and II to this Part. (d) Type examinations must follow the standard specified in Appendix III to this Part. (e) New essay questions shall be raised at least every six months and used questions withdrawn or rested from use. A record of the questions used shall be retained in the records for reference. (f) All examination papers shall be handed out at the start of the examination to the candidate and handed back to the examiner at the end of the allotted examination time period. No examination paper may be removed from the examination room during the allotted examination time period. (g) Apart from specific documentation needed for type examinations, only the examination paper may be available to the candidate during the examination. (h) Examination candidates shall be separated from each other so that they cannot read each other's examination papers. They may not speak to any person other than the examiner. (i) Candidates who are proven to be cheating shall be banned from taking any further examination within 12 months of the date of the examination in which they were found cheating or in accordance with the applicable National Regulation. GM 66.B.200 Examination by CAAB 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 candidates 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. ANO(AW) Part-66 Aircraft Maintenance Licence Chapter 2: Procedures for CAA & Acceptable Means of Compliance (Section B) Issue-2, May 2016 Civil Aviation Authority, Bangladesh 2-11 Nothing however prevents CAAB 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 must be fully identified. (b) All the questions should be of the multiple choice type with three alternatives answers. (c) Questions that require specialized knowledge of specific aircraft types, should not be asked in a basic licence examination. (d) The use of abbreviations and acrionyms should be generally avoided. However where needed, only internationally recognized 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 statements. (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 MCQs is that they can be quickly performed: this is not achieved if doubt exists about the correct answer. (i) The incorrect alternatives must seem equally plausible to anyone ignorant of the subject. All of the alternatives should be clearly related to the question and of similar vocabulary, grammatical construction and length. In numerical questions, the incorrect answers should correspond to procedural errors such as corrections applied in the wrong sense of incorrect unit conversions: they must not be mere random numbers. (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 √10, then the question should specify the approximate value of √10. (k) Questions must be referred to Part-66 Appendix I examination syllabus. 6. Essay question generation: (a) The purpose of the essay is to allow CAAB 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 industry. The essay examination also allows to access, in part, the technical knowledge retained by the individual and with a practical application relevant to a maintenance scenario. ANO(AW) Part-66 Aircraft Maintenance Licence Chapter 2: Procedures for CAA & Acceptable Means of Compliance (Section B) Issue-2, May 2016 Civil Aviation Authority, Bangladesh 2-12 (b) Questions should be written so as to be broad enough to be answered by candidates for all licence category or sub-categories ( Cat A, B1 & B2) 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 1. - 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 a need to ensure consideration is given to the limited practical experience that most candidates will have. (c) In order that 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. (d) When raising questions the following should b
