I am the holder of a B1.2 licence (i.e “aeroplane piston”). Can I exercise my privileges for piston-engine non-pressurised aeroplanes1 of 2000 kg MTOM and below (i.e. category B3)?
By default, a category B3 licence is included in a category B1.2 licence because the basic knowledge requirements (66.A.25(a)) and the basic experience requirement (66.A.30) for a B3 licence are covered by the similar requirements of a B1.2 licence.
Provided that the qualification requirements are fulfilled, the B1.2 licence holder can release maintenance tasks performed on piston-engine non-pressurised aeroplanes of 2000 kg MTOM and below.
In particular the B1.2 licence holder would have to meet 66.A.20(b), which means that:
- the applicable requirements of Part-M, Part-ML, Part-145 and/or Part-CAO will be complied; and
- in the preceding two-year period he/she has 6 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
- he/she has the adequate competence to certify maintenance on the corresponding aircraft; and
- 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 to service are written.
AMC 66.A.20(b)(2) and GM 66.A.20(b)2 gives further explanations on the 6-months maintenance experience in the last 2 years, including demonstration of experience on at least one aircraft type per aircraft structure (metal, composite or wood).1
1 - “Aeroplane” does not include “helicopter”.
