PART-66 /JAR-66.A.45 Type/task training and ratings

a)           The holder of a category A PART-66 /JAR-66 Aircraft Maintenance Licence may only exercise certification privileges on a specific aircraft type following the satisfactory completion of the relevant category A aircraft task training carried out by an appropriately approved Part-145 or Part-147 organization. The training shall include practical hands on training and theoretical training as appropriate for each task authorized. Satisfactory completion of training shall be demonstrated by an examination and/or by workplace assessment carried out by an appropriately approved Part-145 or Part-147 organization.

b)           Except as otherwise specified in paragraph (g), the holder of a category B1, B2 or C PART-66 /JAR-66 Aircraft Maintenance Licence shall only exercise certification privileges on a specific aircraft type when the PART-66 /JAR-66 Aircraft Maintenance Licence is endorsed with the appropriate aircraft type rating.

c)           Except as otherwise specified in paragraph (h), ratings shall be granted following satisfactory completion of the relevant category B1, B2 or C aircraft type training approved by the competent authority or conducted by an appropriately approved Part-147 maintenance training organization.

d)           Category B1 and B2 approved type training shall include theoretical and practical elements and consist of the appropriate course in relation to the PART-66.A.20(a) privileges. Theoretical and practical training shall comply with Appendix III to this Part.

e)           Category C approved type training shall comply with Appendix III to this Part. In the case of a category C person qualified by holding an academic degree as specified in PART-66.A.30(a), (5), the first relevant aircraft type theoretical training shall be at the category B1 or B2 level. Practical training is not required.

f)            Completion of approved aircraft type training, as required by paragraphs (b) to (e), shall be demonstrated by an examination. The examination shall comply with Appendix III to this Part. The examinations in respect of category B1 or B2 or C aircraft type ratings shall be conducted by training organizations appropriately approved under Part- 147, the competent authority, or the training organization conducting the approved type training course.

g)           Notwithstanding paragraph (b), for aircraft other than large aircraft, the holder of a category B1 or B2 PART-66 /JAR-66 Aircraft Maintenance Licence may also exercise certification privileges, when the PART-66 /JAR-66 Aircraft Maintenance Licence is endorsed with the appropriate group ratings, or manufacturer group ratings, unless the Agency has determined that the complexity of the aircraft in question requires a type rating.

1. Manufacturer group ratings may be granted after complying with the type rating requirements of two aircraft types representative of the group from the same manufacturer. 
2. Full group ratings may be granted after complying with the type rating requirements of three aircraft types representative of the group from different manufacturers. However, no full group rating may be granted to B1 multiple turbine engine aeroplanes, where only manufacturer group rating applies. 
3. The groups shall consist of the following: 

(i) for category B1 or C:

• helicopter piston engine 
• helicopter turbine engine 
• aeroplane single piston engine — metal structure 
• aeroplane multiple piston engines — metal structure 
• aeroplane single piston engine — wooden structure 
• aeroplane multiple piston engines — wooden structure 
• aeroplane single piston engine — composite structure 
• aeroplane multiple piston engines — composite structure 
• aeroplane turbine — single engine 
• aeroplane turbine — multiple engine 

(ii) for category B2 or C:

• aeroplane  
• helicopter  

(h) Notwithstanding paragraph (c), ratings on aircraft other than large aircraft may also be granted, subject to satisfactory completion of the relevant category B1, B2 or C aircraft type examination and demonstration of practical experience on the aircraft type, unless the Agency has determined that the aircraft is complex, where paragraph 3 approved type training is required. In the case of a category C ratings on aircraft other than large aircraft, for a person qualified by holding an academic degree as specified in PART-66.A.30 (a), (5), the first relevant aircraft type examination shall be at the category B1 or B2 level.

1. Category B1, B2 and C approved type examinations must consist of a mechanical examination for category B1 and an avionics examination for category B2 and both mechanical and avionics examination for category C. 
2. The examination shall comply with Appendix III to this Part. The examination shall be conducted by training organizations appropriately approved under Part-147, or by the competent authority. 
3. Aircraft type practical experience shall include a representative cross section of maintenance activities relevant to the category.
