The objective of this Notice of Proposed Amendment (NPA) is to mitigate the risks linked to a faulty assessment of the responsibilities of CAMOs and maintenance organisations, especially in relation to the coordination needed in complex maintenance and operational arrangements. This includes the following aspects:
(a) 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;
(b) the responsibilities linked to the performance, coordination and release of maintenance;
(c) the process followed for the release of maintenance.
This NPA mostly affects Part-145 organisations involved in aircraft maintenance (A-rated organisations). Generally, Part-145 organisations involved in component maintenance (B/C/D-rated), Subpart-F maintenance organisations, and independent certifying staff are not involved in such complex maintenance arrangements.
