AMC to Section 6 of Appendix III to Part-66 ‘Aircraft Type Training and Examination Standard On-the-Job Training’    

CAA ORS9 Decision No. 38

On-the-Job Training (OJT)

1. ‘A maintenance organisation appropriately approved for the maintenance of the particular aircraft type’ means a Part-145, M.A. Subpart F or Part-CAO approved maintenance organisation holding an A rating for such aircraft.

2. The OJT should include one to one supervision and should involve actual work task performance on aircraft/components, covering line and/or base maintenance tasks.

3. The use of simulators for OJT should not be allowed.

4. The OJT should cover at least 50% of the tasks contained in Appendix II to AMC to Part-66. Some tasks should be selected from each paragraph of the Appendix II list. Tasks should be selected among those applicable to the type of aircraft and licence (sub)category applied for. Other tasks than those in the Appendix II may be considered as a replacement when they are relevant. Typically, in addition to the variety and the complexity, the OJT tasks should be selected because of their frequency, safety, novelty, etc.

5. Up to 50% of the required OJT may be undertaken before the aircraft theoretical type training starts.

6. The organisation providing the on-the-job training should provide trainees a schedule or plan indicating the list of tasks to be performed under supervision. A record of the tasks completed should be entered into a logbook which should be designed such that each task or group of tasks is countersigned by the corresponding supervisor. The logbook format and its use should be clearly defined.

7. Regarding the day-to-day supervision of the OJT programme in the approved maintenance organisation and the role of the supervisor(s), the following should be considered:

    — It is sufficient that the completion of individual OJT tasks is confirmed by the direct supervisor(s), without being necessary the direct evaluation of the assessor.

    — During the day-to-day OJT performance, the supervision aims at overseeing the complete process, including task completion, use of manuals and procedures, observance of safety measures, warnings and recommendations and adequate behaviour in the maintenance environment.

    — The supervisor(s) should personally observe the work being performed to ensure the safe completeness and should be readily available for consultation, if needed during the OJT performance.

    — The supervisor(s) should countersign the tasks and release the maintenance tasks as the trainee is still not qualified to do so.

    — The supervisor(s) should therefore:

      — have certifying staff or support staff privileges relevant to the OJT tasks;

      — be competent for the selected tasks;

      — be safety-orientated;

      — be capable to coach (setting objectives, giving training, performing supervision, evaluating, handling trainee’s reactions and cultural issues, managing objectively and positively debriefing sessions, determining the need for extra training or reorientate the training, reporting, etc.);

      — be designated by the approved maintenance organisation to carry out the supervision.

    8. Regarding the assessor, the following should be considered:

      — The function of the assessor, as described in Section 6 of Appendix III to Part-66, is to conduct the final assessment of the completed OJT. This assessment should include confirmation of the completion of the required diversity and quantity of OJT and should be based on the supervisor(s) reports and feedback.

      — In Section 6 of Appendix III to Part-66, the term ‘designated assessor appropriately qualified’ means that the assessor should demonstrate training and experience on the assessment process being undertaken and should be authorised to do so by the organisation. Further guidance about the assessment and the designated assessors is provided in Appendix III to AMC to Part-66.

    9. The procedures for OJT of a Part-145 organisation should be included into  the approved maintenance organisation exposition (Chapter 3.20, as   indicated in AMC1 145.A.70(a)).

    However, since these procedures are approved by the CAA 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 is the same as the CAA 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  (refer  to  AMC 66.B.115).
