What is a Part-66 Aircraft Maintenance Licence?

A Part-66 Aircraft Maintenance Licence (AML) is a licence issued by the competent authority in accordance with Annex III (Part-66) to Regulation (EU) No 1321/2014. It confirms that the holder has met the applicable Part-66 requirements for the issue of an Aircraft Maintenance Licence, including the requirements for basic knowledge, maintenance experience and, where applicable, aircraft type or group ratings.

Holding an Aircraft Maintenance Licence (AML) alone does not mean that the holder may exercise certification privileges in all cases without meeting additional requirements. Within a Part-145 organisation, the exercise of such privileges requires a certification authorisation in accordance with point 145.A.35.

Reference: points 66.A.1, 66.A.3, 66.A.20 and 66.B.100 of Annex III (Part-66), and point 145.A.35 of Annex II (Part-145).
