The endorsement of the first aircraft type rating, within a given category/sub-category, requires satisfactory completion of the corresponding On-the-Job-Training (ref. 66.A.45.(c)).
The OJT shall be approved by the competent authority who has issued the licence (ref. Part 66, Appendix III, sec. 6).
It shall be carried out in a maintenance organisation approved under Part-145 (or M.A. Subpart F) with A rating and the procedures for OJT should be included in the exposition (MOE chapter 3.15 “OJT procedure”) approved by the competent authority of the maintenance organisation. However, since these procedures are approved by the competent authority of the maintenance organisation, and providing training is not one of the privileges of a maintenance organisation, they can only be used when the licensing authority (competent authority issuing the license) is the same as the competent authority of the maintenance organisation. In other cases, it is up to the licensing authority to decide whether it accepts such procedures for the purpose of approving the OJT (ref. AMC to Section 6 of Appendix III to Part-66).
For the Part-145 AMOs, whose principal place of business is located outside the EASA Member states, the competent authority of the maintenance organisation is EASA. In such case, the OJT procedures cannot be included in the MOE, due to the fact that EASA is not a licensing authority.
The possibility still exists in this case that a licensing authority may directly approve OJT procedures, which have to be included in a separate document outside (and not being part) of the MOE.
Consequently, personnel working in these AMOs, or the AMOs wishing to support its staff on this matter, should:
- Option A: apply directly to the licensing authority who has issued the license for the approval of an OJT (to be proposed in a document outside the MOE). This option should normally be considered by organisations and not by individuals.
- Option B: find an agreement to follow an already approved OJT at another organisation, which was approved by the same licensing authority who has issued the license. Possibility also exists to follow an OJT which was approved by any other licensing authority, however in such case the final acceptance of this OJT for the purpose of endorsing the first type rating in the license remains at the sole discretion of the competent authority issuing the license.
It is recommended that prior to starting any OJT, the licensing authority who has issued the license is contacted to verify its acceptance of any possible intended option.
