This Advisory Circular (AC) describes an acceptable means of compliance with the general maintenance rules set out in Part 43 General Maintenance Rules in respect to acceptable techniques, methods, and practices in relation to piston engine and propeller inspection and testing, and with the operator maintenance requirements in Part 91 General Operating and Flight Rules.
This AC relates specifically to Civil Aviation Rule Part 43 and Rule 91.603(e) and (f).
Revision 2 adds a paragraph to the Introduction that where reference is made to technical data, it means the current issue or revision of that data.
This AC remains current until a Part 91 AC is published that provides methods acceptable to the Director for the escalation beyond the manufacturer’s TBO for non hire or reward aircraft – refer Rule 91.603(e).
A new AC will be developed to cover the calendar inspection of propellers – refer Rule 91.603(f).
