The completeness of the whole OJT process shall be assessed. The intent of the requirement is not to suggest that:
- there should be an assessment performed by the assessor on top of every task monitored by the supervisor; and/or
- at the very end of the OJT programme, there should be a comprehensive hands-on assessment of the candidate on a real aircraft as an additional and ultimate evaluation
All report(s) or feedback from the supervisor(s) having monitored every actual job task performance or any other source of information (use of manuals and procedures; observance of safety measures, warnings and recommendations; adequate behaviour in the maintenance environment), the designated assessor should be in a position to:
- ensure that the OJT procedure was fully met (in terms of objective and content); and
- check that the competence of the candidate was positively assessed.
In case of doubt, the assessor may decide to proceed him/herself to an additional evaluation of the candidate or perform a gap analysis when the OJT procedure is not fully met such as an insufficient number of tasks or diversity of tasks or unclear supervisor’s report regarding the candidate’s performance. The supervisor should not sign the actual task if the person did not achieve the required competence in safe task performance.
Note: It is worth being reminded here that OJT addresses:
- the first type rating in a (sub)category of aircraft; and
- subsequently addresses young mechanics (e.g. “newcomers”) or mechanics having no experience in that new (sub)category of aircraft (e.g. extension of the license).
AMC to Section 6. of Appendix III to Part-66 gives more clarification about the assessment process and the function of the assessor:
- “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”, and
- “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”.
It is left to the decision of the competent authority how to comply with this requirement: the AMC as suggested by the Agency aims at avoiding additional burden, duplication or over-regulation while proposing a simple final evaluation process.
