Part M And It's Subparts Explained

It used to be a lot more simple to own and operate a light aircraft, however EASA has now taken control of maintenance regulation in Europe and there are many more regulations than there used to be. We offer Part M services which take the headache away from you as regards the fulfilment of these requirements.

Silverstar Maintenance Services can provide full Part M Subparts G and I support.

Part M Subpart G

Part M is the overall reference or "master regulation" in the EASA rules under which aircraft maintenance is now managed.

Subpart G is a system also known as Continued Airworthiness Management. The role of a Continued Airworthiness Management Organisation (CAMO) is to generate maintenance schedules and work packs for an appropriate maintenance company to work from and organise the hangar visits accordingly.

The CAMO is required to be Part M approved and must organise, plan and schedule the following;

An organisation which conducts the actual maintenance does not have to be Part M approved but must take it's maintenance instructions from someone responsible for the airworthiness management of that aircraft. (Usually a Part M organisation)

Most light aircraft maintenance companies are gaining their Part M approval so that they can effectively commission themselves to work on the aircraft which they previously managed outside of this environment.

It is possible however that a separate Part M approved CAMO run by another company or individual can administrate the maintenance for an aircraft which is physically maintained by a non Part M Subpart G approved organisation.

Key Points - Part M And Continued Airworthiness Management

Once your aircraft is contracted to a Part M Subpart G approved organisation (CAMO) it is then said to be in a "controlled environment" or under "continued airworthiness management".

If any work is to be conducted on your aircraft after this point it must be commissioned by the CAMO responsible for the aircraft, not directly by the owner.

An owner must liaise with the CAMO if work is to be requested and the CAMO in turn will commission an appropriate approved maintenance organisation to do the work.

A CAMO (Part M Subpart G organisation) is like an administrator for the work required.

A maintenance organisation (Typically a Part 145 organisation) is like a garage commissioned to complete the work.

Part M Subpart I

Remembering that Part M is the overall reference or "master regulation" in the EASA rules under which aircraft maintenance is now managed and its "Subparts" enable different functions to be performed under this regulation, Subpart I is the the regulation which enables an organisation to generate its own ARC (Airworthiness Review Certificate) renewals when they fall due.

Having this ability means that the Part M organisation no longer has to involve the CAA or EASA externally in order to renew the required documentation on an annual basis and can produce a fresh ARC in house at the time of the renewal.

Key Points - ARC Renewal Under Subpart I

Your ARC (Airworthiness Review Certificate) falls due for renewal on an annual basis.

It is the responsibility of the CAMO to review the documentation, maintenance schedules, Service Bulletins and Airworthiness Directives and ensure compliance has been met with all required maintenance action thoroughly at the time of renewal.

Usually this process coincides with your annual maintenance however it does not have to do so. If it doesn't, a small inspection may be required in order to satisfy the requirements. If the aircraft has been under continued airworthiness management with our organisation anyway, this is largely a paperwork exercise.

Once all of the requirements are fulfilled, under Part M Subpart I we can then re-issue you with a new ARC valid for another 12 months.
