CD 1611MS - Transfer of certain recurring maintenance requirements from ADs to the Part 42 MOS
Part 39 of the Civil Aviation Safety Regulations 1998 (CASR) provides that an AD can be issued to rectify an unsafe condition in a particular aircraft type or in specific equipment arising out of a design deficiency, or a production and manufacturing fault. During a review of Australian unique airworthiness directives (ADs), CASA identified a number of recurring maintenance-related ADs that did not fully satisfy the criteria for the issue of an AD under Part 39 of CASR.
These ADs, listed in Appendix A, relate to aircraft systems and equipment that are generally common to all aircraft types and are essential for safe operation of an aircraft. The recurring maintenance requirements contained in these ADs ensure continuing serviceability of these systems and equipment. A number of these ADs were prematurely cancelled with the intent that the requirements of the cancelled ADs would be included in Civil Aviation Order 100.5 or the Part 42 Manual of Standards in due course. The Appendix identifies both the current and cancelled ADs.
