Consistent with our regulatory philosophy, CASA applies a risk based regulatory approach, with the highest safety priority given to commercial passenger transport operations.
Following the repeal of any wing bolt ADs, CASA proposes to issue a direction requiring that the instructions for continuing airworthiness be considered in the continuing airworthiness management of aircraft used in air transport operations. Under this direction the registered operator would be required to have a system in place to monitor the aircraft manufacturer’s instructions for continuing airworthiness that relate to aircraft safety, and take appropriate action as required.
CASA considers this direction emphasises an existing continuing airworthiness management responsibility of AOC holders for air transport operations
The following continuing airworthiness arrangements would be considered sufficient to meet the intent of the direction:
- compliance with the manufacturer’s maintenance schedule (i.e. maintaining the aircraft in accordance with the manufacturer’s instructions for continuing airworthiness);
- an approved system of maintenance that is being kept up to date by the operator; or
- an approved maintenance program under CASR Part 42.
