They are valid. The only difference is that the certificate of recognition on which they appear corresponds to the EASA 148 format, while the basic examinations approved as of 12 June 2024 will appear in an EASA 148a format if they have been carried out in a Part 147 organisation, or in an EASA 148b format (if they have been carried out with the Authority).

How can you perform an OJT?:

Once the OJT is completed, when you want to incorporate the type rating in the license, the following documentation will be sent to AESA:

Point 1 of Appendix III of Annex III (Part-66) to Regulation (EU) 1321/2014 provides that theoretical and practical training must have been initiated and completed in the three years preceding the application for the entry of the type rating, regardless of whether an LMA Part 66 licence is already held or not.

The appointment must be made in writing by the quality manager of the organisation, which is prior to the start of the OJT. There must also be a signature of “received” by the data subject (evaluator or supervisor) in order to justify that he is aware of his or her role. There is no established format for such appointments.

Regulation (EU) No 1321/2014 provides in paragraph (b) of 66.A.25 that basic training courses and examinations shall be conducted within the 10 years preceding the application for an aircraft maintenance licence or the addition of a category or subcategory to that licence.

Those modules that have passed 10 years will need to be re-examined if the syllabus of these modules has changed since it was approved until the date on which the license is requested. If the agenda of those modules had not changed, it would not have to be reconsidered.

Applicants who complete basic training at an approved Part 147 organisation and then pass the examinations in another approved Party 147 organisation, will be granted full basic course consideration and, therefore, the reduction of the basic experience requirement will be maximum, eventually remaining within 1 or 2 years.
