The maintenance suite of Civil Aviation Safety Regulations (CASR) Parts 42, 66, 145 and 147 came into effect on 27 June 2011.
The regulations were amended to broaden the scope of privileges for aircraft operators and maintenance organisations and allow a Part 42 Continuing Airworthiness Management Organisation (CAMO) and a Part 145 Approved Maintenance Organisation (AMO) to provide continuing airworthiness management services and aircraft maintenance services for aircraft used in regular public transport.
The changes also introduced the EASA B1 and B2 maintenance licence system and the Part 147 aircraft maintenance training school standards.
Overview of the regulations
Part 42 sets out continuing airworthiness requirements for aircraft and aeronautical products.
Part 66 applies to individuals seeking an aircraft engineer licence or licence rating and sets out requirements for the application for, the granting of, and the appropriate use of aircraft maintenance engineer licences and ratings.
Part 145 sets out matters relating to approved maintenance organisations and maintenance personnel requiring authorisation for the performance of maintenance certifications and the issue of certificates of release to service to aircraft and aeronautical product maintenance.
Part 147 sets out matters relating to approved maintenance training organisations, training personnel requiring licences and ratings for the performance of maintenance certifications and certificates of release to service for aircraft maintenance.

Proposed regulation development
As part of the Regulatory Reform Program (RRP), the Civil Aviation Regulations 1988 (CAR) are progressively being replaced by the Civil Aviation Safety Regulations 1998 (CASR). The RRP has already transitioned most of the airworthiness regulations to CASR. However, aircraft in the private, aerial work and charter sectors are still maintained under CAR.
We are currently developing new continuing airworthiness and maintenance regulations to cover the private, aerial work and charter sectors. This will be undertaken in two streams:
- Part 43 – Maintenance of general aviation and aerial work aircraft
- Charter – continuing airworthiness regulation requirements
For the latest information on the proposed regulations subscribe to our mailing lists, consultation and rule making, maintenance regulations – change the rules and regulatory implementation.
We have a seminar program to help keep you up to date on continuing airworthiness and maintenance.
