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:
o have certifying staff or support staff privileges relevant to the OJT tasks;
o be competent for the selected tasks;
o be safety-orientated;
o 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.);
o 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 con
