Opinion 06/2013

Critical maintenance tasks

Opinion of the European Aviation Safety Agency for a Regulation amending Commission Regulation (EC) No 2042/2003, on the continuing airworthiness of aircraft and aeronautical products, parts and appliances, and on the approval of organisations and personnel involved in these tasks.

This Opinion addresses a safety issue related to the risk of errors made during the performance of critical maintenance tasks and the need for maintenance organisations to implement methods to capture those errors before the certificate of release to service is issued.

The safety recommendations linked to this Opinion were debated by the working group during the development of this proposal and were listed in the NPA 04-2012.

The specific objective of this proposal is to mitigate the risks linked to the performance of maintenance, by clarifying the requirements for the identification of critical maintenance tasks and the need to implement measures necessary to detect errors made in the performance of those tasks.

This Opinion proposes amending the requirements for performance of maintenance in Part-M namely point M.A.402, and the introduction of specific requirements for the performance of maintenance by Part-145 organisations, namely point 145.A.48

The proposed changes are expected to increase safety and improve compliance.
