The maintenance suite of regulations does not apply to all sectors of aviation operations.
- Part 42 (covering continuing airworthiness requirements) and Part 145 (covering approved maintenance organisations) apply to only the regular public transport sector.
- Part 66 covers maintenance personnel licensing.
- The current maintenance regulations covering other sectors of operations, such as charter, general aviation and aerial work, will be revised at a later date.
Regular Public Transport (RPT) Aircraft Operators - Part 42
As a Registered Operator (RO) of aircraft operating under a RPT AOC, you must hold a Continuing Airworthiness Management Organisation (CAMO) approval.
As a CAMO managing the airworthiness of aircraft operated in RPT, you need to employ the maintenance services of a Part 145 approved maintenance organisation for the aircraft and its related aeronautical products.
Maintenance Organisations - Part 145
If you provide maintenance services for aircraft or aeronautical products operated in RPT, you need to hold a Part 145 AMO approval.
You will need to provide those maintenance services within the scope of the AMO's approval, working to the maintenance performance rules of CASR Part 42 and in accordance with the instructions for continuing airworthiness provided by the CAMO for the aircraft.
Additionally design data approved under Part 21 for modifications and repairs will be used by Part 145 AMOs performing maintenance to standards and performance rules of Part 42.
Maintenance Engineers - Part 66
As a Licensed Aircraft Maintenance Engineer (LAME), you will have been issued a Part 66 licence equivalent in scope to your previous AME licence but in the A1, B1, B2 and C category format.
You can use this licence in a Part 145 Approved Maintenance Organisation (AMO) or in a CAR 30 AMO.
The CAR 31 to Part 66 transitional regulation ceased on 26th June 2015. If you want to apply for an initial Part 66 licence or additional category/type rating, you will need to go through a CASA 147 Maintenance Training Organisation (MTO).
As of the 26th June 2015, you can continue to use AME basic examinations and SOE, to apply for a Part 66 licence for small aircraft maintenance, or remove exclusions from a type rating/category on your Part 66 licence.
Maintenance Training Organisations - Part 147
If you provide aircraft maintenance training leading to a Part 66 licence category or aircraft type rating outcomes, you will need to work in a Part 147 MTO or have a Part 147 MTO approval.
An MTO will be expected to establish appropriate relationships with maintenance organisations to access aircraft and aeronautical products for on-aircraft practical training if required.
