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.

AC92-4, Revision 0, Dangerous Goods Manuals [PDF 566 KB]
The initial draft of this AC has been completed and is ready for consultation.
This AC describes an acceptable means of compliance with requirements to have a Dangerous Goods (DG) manual in an operator’s exposition, particularly for smaller operators. It also provides operators who are not certificated with a sample DG manual.
As part of this AC, we have drafted sample manuals for “will carry” and “will-not-carry” operators. While operators still have to work through their own circumstances in drafting their manuals, we hope that these will prompt operators to create robust and detailed manuals that will help them manage DG safely in their day-to-day operations. Ideally this AC would be read in conjunction with other ACs in the 92 series.
In the current draft we have included the manuals in the AC itself – we would welcome feedback from participants as to whether this format is useful, if published as a Word document, or whether it would be easier for them to be published as separate documents.
