Only a Part-147 organisation has the privilege (if approved by its competent authority) to provide aircraft type training courses. This comprises both the theoretical and practical element of the aircraft type training, including the related examinations and assessments. This means that the practical element of the aircraft type training shall be completed in a Part-147 organisation.
However, the aircraft type training may be conducted physically in a Part-145 organisation under the control (and as a part of the approval) of a Part-147 organisation issuing the Certificate of Recognition. It is not the privilege of the Part-145 organisation to conduct aircraft type training courses on its own.
In addition, the theoretical and practical element of the aircraft type training can be conducted by two different approved Part-147 organisations. The competent authority endorsing the type rating on the license should be convinced that the interfaces have been correctly addressed before proceeding thereof (66.B.115(b) refers).
In the special case where the aircraft type course is directly approved by the competent authority in accordance with the procedure 66.B.130 (i.e. only on a case by case basis – special authorization not granted for long term periods), the training can be conducted outside the scope of a Part-147 organisation. As a consequence, the certificate issued is not mutually recognized between Member States, which means it can only be used for aircraft type endorsement by the licensing authority who issued that direct approval.
