CASR Part 42 – Continuing airworthiness

Proposed CASR Part 42 is equivalent to the EASA Part M and provides the overall policy directions for the whole of the maintenance suite of regulations including individuals and approved maintenance organisations. It is written in an outcome-based style and provides direction on the requirements for maintenance based on both the size of aircraft and sector of the aviation industry.

In an Australian context, Part 42 is equivalent in the previous NPRM0407MS to a combination of the individual Subparts M (airworthiness and maintenance control) and Part 43 (maintainer’s responsibilities), and:

  • Establishes responsibilities of individuals or organisations and the measures to be taken to ensure that continuing airworthiness (CAW) is maintained;
  • Specifies the conditions to be met by persons or organisations involved in such CAW management;
  • Establishes that the registered operator is responsible for CAW of an aircraft;
  • Establishes that maintenance of large aircraft, including those for Public Air Transport, must be carried out by a Part 145 approved maintenance organisation (AMO);
  • Provides the requirements for a Subpart F – Maintenance Organisation which is not a Part 145 maintenance organisation. A Subpart F organisation is a smaller maintenance organisation which can maintain small aircraft. The Subpart also provides the authority to issue an organisational approval for such an organisation;
  • Provides the concept overview and requirements for a Subpart G – Continuing Airworthiness Management Organisation (CAMO) and the authority to issue an organisational approval for such an organisation;
  • Allows the registered operator to contract the tasks for CAW to a Continuing Airworthiness Management Organisation (CAMO);
  • Provides overview of the airworthiness review process which is undertaken annually for most aircraft and the Airworthiness Review Certificate; and
  • Provides detail on the requirements for the Certificate of Release to Service (CRS) after maintenance undertaken under Part 42 and therefore covers the privileges of CRS and the differing restrictions:
    • within a Subpart F organisation;
    • for the Part 66 LAME not working in an organisation; and
    • for the owner/pilot of a privately-operated aircraft.
