Information for Maintenance Organisations and CAMOs

Information for Maintenance and Continuing Airworthiness Management Organisations

In accordance with Regulation (EC) 2042/2003, all EASA aircraft types that qualify for an EASA Certificate of Airworthiness (CofA) are issued with a non-expiring CofA, validated annually with an Airworthiness Review Certificate (ARC).

To find out how the implementation of Part M will affects your organisation, please see below.

Please Note:

Aircraft not used for Commercial Air Transport may not have their ARCs extended, even if they have remained under the management of a unique CAMO for the past year. This is currently only available to Commercial Air Transport aircraft as, for them, Part M has been applicable since September 2007.

An aircraft must have remained in a Controlled Environment under Part M for 12 months before an ARC may be extended. Since Part M became applicable to Non-Commercial Air Transport from 28 September 2008, only ARCs issued after that date may be extended on expiry (Provided that the aircraft has remained under the management of a unique CAMO and has been maintained by a suitably approved maintenance organisation for 12 months preceding ARC expiry).


Latest News:

In September 2008 the CAA issued exemption E2610 that permitted organisations not approved under EASA regulations to continue to issue a Certificate of Release to Service (CRS) under their national CAA approval until 5 January 2009.

From the 6 January 2009, organisations who have not yet been approved under Part M Subpart F or Part 145 are no longer be able to use the privileges of their national approval to release to service aircraft subject to EASA regulation.

For those organisations who are still finalising their new approvals, the CAA would like to clarify that many aircraft maintenance tasks may still be released to service under the privileges granted to Part 66 licensed personnel.

Part M Subpart G Organisations (without ARC privileges)

Organisations approved in accordance with EASA Part M Subpart G are able to do the following;

  • Manage the continued airworthiness of aircraft that fall within their scope of approval.
  • Extend the validity of ARCs (15a and 15b) for all aircraft types within their scope of approval provided that the aircraft has remained in a Controlled Environment for 12 months prior to the extension of the ARC validity and you have been approved to do so. Further information in available in CAA guidance document 'Extension of the CAA Issued ARC - Form 15a'

Please note the following changes to the Airworthiness Review Certificate Extension Process in the latest amendment to Part M (ED Decision No 2008/013/R of 12/12/2008), effective from 19th December 2008.

  • The anticipation period for extending an Airworthiness Review Certificate (ARC) is now increased to a maximum of thirty (30) days from the expiry date (previously this was 14 days).
  • It is now acceptable to extend the ARC after the expiry date provided the aircraft could not fly since the expiry date of the last ARC. The new expiry date, after the extension, remains one year after the expiry date of the last ARC


Part M Subpart G Organisation with ARC Privileges

Organisations approved in accordance with EASA Part M Subpart G that hold the ARC privileges required for ARC Issue will be able to do the following;

  • Issue an ARC for all aircraft types within their scope of approval that are used for Commercial Air Transport and have remained in a Controlled Environment for 12 months preceding ARC expiry.
  • Issue an ARC for all aircraft types within their scope of approval that are below 2730 kgs MTOM and not used for Commercial Air Transport.
  • Extend the validity of ARCs for all aircraft types within their scope of approval provided that the aircraft has remained in a Controlled Environment for 12 months prior to Extension of ARC validity.
  • Recommend the Issue of an ARC for aircraft types within their scope of approval if the aircraft has not remained in a Controlled Environment.

Please note the following changes to the Airworthiness Review Certificate Extension Process in the latest amendment to Part M (ED Decision No 2008/013/R of 12/12/2008), effective from 19th December 2008.

  • The anticipation period for extending an Airworthiness Review Certificate (ARC) is now increased to a maximum of thirty (30) days from the expiry date (previously this was 14 days).

Maintenance Organisations with Other National Approvals

For those organisations who are still finalising their new approvals, the CAA would like to clarify that many aircraft maintenance tasks may still be released to service under the privileges granted to Part 66 licensed personnel.


Certificates of Release to Service

Independent Certifying Staff and Organisations Holding National Maintenance Approval Under BCAR A8-15

All aircraft Certificates of Release to Service must be issued by appropriately rated Part 66 licensed personnel in accordance with Part M. Where there is a need to accomplish a 'complex task' (defined in Part M Appendix VII) an organisation holding the appropriate EASA approval should be contracted.

For aircraft with a MTOM below 1000 kg, classified as an ELA1 aircraft, which are not used in commercial air transport:

Maintenance, including complex tasks, may be performed and certificates of release to Service issued by an appropriately rated Part 66 licensed engineer.

In both cases the release to service statement shall be made in accordance with Part M, M.A.801(b) 2.

Note: An ELA 1 aircraft is defined as:

  • A non complex aircraft with a Maximum Take Off Mass (MTOM) of less than 1000 kg;
  • Hot air balloons of not more than 3400 m³;
  • Gas balloons of not more than 1050 m³;
  • Tethered gas balloons of not more than 300 m³;
  • Hot-air airships designed for not more than 2 occupants and of not more than 2500 m³;
  • Gas airships designed for not more than 2 occupants and of not more than 1000 m³

Organisations Holding Subpart F or Part 145 Approval

For Organisations Holding Subpart F or Part 145 Approval, the Certificates of Release to Service shall be issued in accordance with M.A.801 (a) or M.A.801 (b) 1.


Applying for ARC privileges

ARC privilege approval may be granted to approved Part M Subpart G organisations that meet the requirements set out in Subpart I of Regulation (EC) 2042/2003.

To apply for approval, EASA Form 2, together with the appropriate fee, should be sent to the Applications and Approvals Department. Details of costs can be found in the CAA Scheme of Charges - Airworthiness, Noise Certification and Aircraft and Aircraft Engine Emissions.

Changes to the Scheme of Charges - Airworthiness, Noise Certification and Aircraft and Aircraft Engine Emissions are also in progress to replace the multiple approval fees, which would be levied in April 2009 by a reduced combined fee for smaller organisations. These changes are undergoing consultation at this time.
