GM1 147.A.145(d) Privileges of the maintenance training organisation

1. […] 3. The reason for allowing the subcontracting of training modules 1 to 6 and 8 to 10 only is that, most of the related subjects can generally also be taught by training organisations not specialised in aircraft maintenance and the practical training element, as specified in point 147.A.200, does not apply to them. On the contrary, the other training modules 7 and 11 to 17 are specific to aircraft maintenance and include the practical training element as specified in point 147.A.200. The intent of the ‘limited subcontracting’ option as specified in point 147.A.145 is to grant Part-147 approvals only to those organisations having themselves at least the capacity to teach on aircraft-maintenance-specific matters.
