The European Aviation Safety Agency last week issued a notice of proposed amendment intended to “mitigate the risks linked to a faulty assessment of the responsibilities of continuing airworthiness management organizations [Camos] and maintenance companies,” especially in relation to the coordination needed in “complex” maintenance and operational arrangements.

According to the NPA, this coordination effort addresses the following matters: the responsibilities linked to the determination of the airworthiness of the aircraft, including the procedures and documentation needed to ensure its notification to the flight crew; the responsibilities linked to the performance, coordination and release of maintenance; and the process followed for the release of maintenance.

The proposal would affect Part 145 maintenance shops based in Europe that work on commercial air transports (including charter and air-taxi aircraft). Most general aviation aircraft (except those for hire) and Part 145 companies that provide parts maintenance are not involved in such “complex” maintenance arrangements, and thus not covered by this proposal. Comments on the NPA are due by Feb. 3, 2015.
