Type and task training
Aircraft type and task training is its own Part-147 approval. It is an approval to carry out Part-66 aircraft type and/or task training, and only where that training complies with point 66.A.45.
A maintenance training organisation shall be approved to carry out Annex III (Part-66) aircraft
type and/or task training subject to compliance with the standard specified in point 66.A.45.
Quoted word for word from Regulation (EU) No 1321/2014, Easy Access Rules for Continuing Airworthiness, 2 Sep 2025 revision.
The training organisation does not set the type standard. Point 66.A.45 does. How the licence is endorsed is the subject of the Part-66 experience and application guide.
Evaluation and assessment
A maintenance training organisation approved in accordance with point 147.A.300 to conduct
aircraft type training shall conduct the aircraft type evaluation or aircraft task assessment
specified in Annex III (Part-66) subject to compliance with the aircraft type and/or task
standard specified in point 66.A.45 of Annex III (Part-66).
Quoted word for word from Regulation (EU) No 1321/2014, Easy Access Rules for Continuing Airworthiness, 2 Sep 2025 revision.
The organisation approved to conduct aircraft type training shall conduct the aircraft type evaluation or the aircraft task assessment. Both stay subject to the standard in point 66.A.45.
What an endorsement requires
(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 their licence endorsed with the
relevant aircraft ratings:
[…]
(b)The endorsement of aircraft type ratings requires the satisfactory completion of one of the
following:
the relevant category B1, B2 or C aircraft type training in accordance with Appendix III to
Annex III (Part-66);
in the case of gas airship type ratings on a B2 or L5 licence, a type training approved by the
competent authority in accordance with point 66.B.130.
[…]
(c)For other than category C licences, in addition to the requirements of point (b), the
endorsement of the first aircraft type rating within a given category/subcategory requires
satisfactory completion of the corresponding on-the-job training. This on-the-job training shall
comply with Appendix III to Annex III (Part-66), except in the case of gas airships, where it
shall be directly approved by the competent authority.
[…]
(d)By derogation from points (b) and (c), for Group 2 and 3 aircraft, aircraft type ratings may
also be endorsed on a licence after completing the following steps:
satisfactory completion of the relevant category B1, B2 or C aircraft type evaluation in
accordance with Appendix III to this Annex (Part-66);
in the case of B1 and B2 category, demonstration of practical experience in the aircraft type.
In that case, the practical experience shall include a representative cross section of
maintenance activities relevant to the licence category.
[…]
Quoted word for word from Regulation (EU) No 1321/2014, Easy Access Rules for Continuing Airworthiness, 2 Sep 2025 revision.
To exercise certification privileges on a specific aircraft type, the holder needs the licence endorsed with the relevant aircraft ratings. Point (a) then lists those ratings. This page does not restate that list.
Point (b) is the aircraft type training, or the competent-authority type training for a gas airship on a B2 or L5 licence. Point (c) adds the corresponding on-the-job training for the first aircraft type rating in a category or subcategory, for other than category C licences. Gas-airship on-the-job training shall be directly approved by the competent authority. Point (c) continues after the sentences quoted here.
Point (d) is a derogation from points (b) and (c) for Group 2 and 3 aircraft: a type evaluation, and, for B1 and B2, practical experience in the aircraft type. The on-the-job training in point (c) is not added on top of that derogation. Point (d) continues after the sentences quoted here.
How this feeds the licence
Identify the route first. Part-147 type training is the training in point (b). The first rating in a category or subcategory other than C also has the on-the-job training in point (c), except where point (d) is the derogation being used. The Part-66 experience and application guide places the rating next to basic knowledge and experience.
Where to read it yourself
Type and task training are 147.A.300 and 147.A.305 in Annex IV (Part-147). The endorsement rule is 66.A.45 in Annex III (Part-66), and Appendix III to that annex is the type-training standard those points name. All of this is in the EASA Easy Access Rules for Continuing Airworthiness (Regulation (EU) No 1321/2014). Every citation in this guide was checked against the 2025-09-02 revision.
