AC145-1 Revision 8, Aircraft Maintenance Organisations [PDF 692 KB]

This AC has been revised, following a request for CAA to clarify the necessary requirements for training of staff to certify components for release to service. Every Part 145-Certificated organisation will have established authorisation procedures, including the assessment of staff prior to the issuance of an authorisation. In the case of organisations maintaining components, authorisation procedures will identify the relevant component technical training course which must be undertaken prior to an authorisation being issued.

AC145-1 provides guidance to organisations who choose to establish an internal training function to address this requirement. In Section 6, Training and assessment (E1 rating or internal training) this AC identifies ATA Specification 104, Guidelines for Aircraft Maintenance Training, as guidance material for organisations choosing to conduct internal training. ATA Specification 104 expands on the guidance in this AC and provides a framework for organisations conducting technical training. Therefore, it is strongly suggested that ATA Specification 104 and AC145-1 are read in combination when establishing the relevant training.
