(a)Where the type training has not been conducted by a Part-147 organisation, there should be supporting documents confirming to the competent authority that: The type training has been approved by the competent authority in accordance with 66.B.130, the applicant has completed the elements of the approved type training; and the trainee has been successfully examined/assessed.

(b)Aircraft type training may be subdivided in airframe and/or powerplant and/or avionics/electrical systems type training courses.

1.Airframe type training course means a type training course including all relevant aircraft structure and electrical and mechanical systems excluding the powerplant.

2.Powerplant type training course means a type training course on the bare engine, including the build-up to a quick engine change unit.

3.The interface of the engine/airframe systems should be addressed by either airframe or powerplant type training course. In some cases, such as for general aviation, it may be more appropriate to cover the interface during the airframe course due to the large variety of aircraft that can have the same engine type installed.

4.Avionics/electrical systems type training course means type training on avionics and electrical systems covered by but not necessarily limited to ATA Chapters 22, 23, 24, 25, 27, 31, 33, 34, 42, 44, 45, 46, 73 and 77 or equivalent.

(c)For the acceptance of the OJT tasks and programme, the licensing competent authority should develop procedures compliant with Section 6 of Appendix III to Part-66. In the case where the licensing competent authority is different from the competent authority of the maintenance organisation which provides the OJT, the licensing authority may take into consideration the fact that the maintenance organisation may already have the OJT programme accepted by their own competent authority (directly approved or through Chapter 3.20 of the MOE, as described in AMC1 145.A.70(a)).
