Apply for or vary a Certificate of Approval (CAR 30)

There are two regulations for maintenance organisations:

  • Part 145 of Civil Aviation Safety Regulations (CASR) approved maintenance organisations (AMO)
  • Regulation 30 of the Civil Aviation Regulations (CAR) Certificates of approval (COA).

The approval you need depends on the type of flying operations carried out with the aircraft. Also, the type of components you wish to maintain.

A COA will allow you to maintain registered aircraft and components not used for scheduled air transport operations.

For certain other types of operations, you must become a Part 145 AMO. These include:

  • scheduled air transport operations
  • when registered operators elect Part 42 applies to the aircraft for:
    • non-scheduled air transport, medical transport, or aerial application operations
    • large aircraft not authorised to operate under an Air Operator’s Certificate

We give further guidance on how to apply to be a Part 145 Approved Maintenance Organisation.

Replacing CAR 30 with Part 145 for maintenance approvals

Part 145 of CASR will replace Regulation 30 of CAR as part of the regulation reform project. After the transition period, Part 145 CASR will be the only type of approval you need to be a maintenance organisation.

We recommend new entrants become a Part 145 Approved maintenance organisation (AMO).

If you are thinking of varying or applying for a Certificate of Approval (COA), you should consider becoming a Part 145 AMO instead. This is the preferred approach as it will reduce your future transitional burden moving to the Civil Aviation Safety Regulations 1998.
