Privileges of a Part-66 licence

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”.

The competent authority of the Member State issuing the licence may include in the Annex (Section XIV) of EASA Form 26 types for which the Basic Regulation is not applicable. The privileges endorsed for these types are based only on the national rules. The use of Section XIV of EASA Form 26 is optional.

EASA does not have any information about these types. If you want to get information about them, please contact the competent authority.

The “validity” of the Part-66 licence is not affected by point 66.A.20(b)(2). The licence itself remains valid 5 years from the last renewal.  
Nevertheless, compliance with point 66.A.20(b)(2) is required to ensure that the maintenance privileges are exercised by certifying staff that hold sufficient recent experience.
If you do not meet this point anymore, you lose your rights to exercise your privileges of certifying staff or support staff. 
Therefore, as holder of an aircraft maintenance licence, to exercise your certification privilege in accordance with 66.A.20(b)(2), please ensure:

•  You have accumulated 6 months of experience in the previous 2 years;

Note: see also AMC 66.A.20(b)(2) for possible reductions of experience, in particular for independent certifying staff. Demonstration of experience should be made on the particular or similar aircraft. Guidance on ‘similar’ aircraft is also provided in AMC 66.A.20(b)(2).

or

•  You can demonstrate that in the last 2 years, you have met the provisions for the issue of appropriate privileges, which means (refer to 66.A.45), as applicable to the case:

1)    going to a type-training course again (the need for OJT has to be assessed on case-by-case basis);

or

2)    when the aircraft endorsement does not require type training (aircraft belonging in Group 2, 3 or 4):

       a) pass a type evaluation, including practical assessment; 
or
        b) when no type evaluation is required for aircraft endorsement, for example:
            - a B2/B2L license endorsed with a full group 3 or 4 rating; or
            - for L-category licences (other than L5), 
being able to demonstrate, in the last 2 years, practical experience, which shall include a representative cross section of maintenance activities relevant to the licence subcategory (B2/B2L, L1, L1C, L2, etc.)

Note: “A representative cross section of maintenance activities” means representative cross-section of the tasks listed in Appendix II to AMC to Annex III (Part-66) “Aircraft Type Practical Experience and On-the-Job Training - List of Tasks”. “Demonstrate” means having a record thereof, such as a logbook.
Note: GM 66.A.20(b)2 will be reviewed and amended according to this interpretation  through rulemaking task RMT.0735.
 

The list of typical tasks to be carried out by a category A certifying staff at the line shown in the AMC include a (r) stating: “Any other task agreed by the competent authority as a simple task for a particular aircraft type. This may include defect deferment when all the following conditions are met:

• there is no need for troubleshooting; and
• the task is in the MEL, and
• the maintenance action required by the MEL is agreed by the competent authority to be simple.

When these conditions are met, your authority may allow other tasks to be carried out under AMC 145.A.30(g).
