UK Civil Aviation Regulations

These are published by the CAA on our UK Regulations pages. EU Regulations and EASA Access Guides published by EASA no longer apply in the UK. Our website and publications are being reviewed to update all references. Any references to EU law and EASA Access guides should be disregarded and where applicable the equivalent UK versions referred to instead.

This page provides guidance to organisations wishing to apply for a UK Part-CAMO approval as part of an application for an Air Operators Certificate (AOC).

UK Regulation (EU) No 1321/2014, Annex Vc (Part-CAMO) concerns the continuing airworthiness management for organisations relating to all Part 21 aircraft but is a mandatory requirement for the management of Complex Motor-Powered Aircraft (CMPA), and/or aircraft used by a licensed air carrier.

Organisations approved to Part-CAMO can additionally be approved to make recommendations to the Civil Aviation Authority (CAA) for the issue of Airworthiness Review Certificates (CAA Form 15a) or in certain cases issue and extend Airworthiness Review Certificates (CAA Form 15b or CAA Form 15c, as applicable) under the terms of their approval.

Part-CAMO organisations holding the Airworthiness Review privilege may also be approved to issue Permits to Fly in accordance with (UK) Part 21 Subpart P when the aircraft is in conformity with the approved Flight Conditions. This privilege does not allow the Part-CAMO organisation to approve the Flight Conditions.

How do I apply?

Applications for a Part-CAMO approval required as part of an Air Operators Certificate should be submitted to CAA Flight Operations in the first instance. Refer to guidance on AOC applications.

What happens next?

The guidance below advises on what to expect once you have applied:

A Technical Support Officer will make an initial assessment of your application and associated documents and will contact you with any queries.

The Resource Scheduling Team will contact you to arrange for an Airworthiness Surveyor to carry out an on-site audit. Any questions regarding the scheduling of your on-site visit can be directed to the Resource Scheduling Team email ResourceScheduling@caa.co.uk.

An Airworthiness Surveyor will conduct an audit(s) against the requirements and raise an audit report detailing any findings.

The Airworthiness Surveyor will review the nominated personnel. Interviews for key personnel may be carried out.

The Airworthiness Surveyor will assess the supporting documentation; Technical Logs, Maintenance Contracts (as applicable) and Maintenance Programmes. When able to, the Airworthiness Surveyor will approve the supporting documentation.

If findings have been raised the organisation should address the findings and notify the Airworthiness Surveyor of the actions taken.

Once any audit findings relating to the application have been closed the Airworthiness Surveyor will submit a recommendation to the Shared Services Approval team for the issue of the approval.

If you have been approved to Issue or Extend Airworthiness Review Certificates (ARC) under your Part-CAMO approval, at this stage we will send you an e-mail containing your ARC Online logon information.

How long is it valid for?

The organisation’s certificate shall remain valid subject to compliance with all of the following conditions:

  • The organisation remaining in compliance with UK Regulation (EU) 2018/1139 and its delegated and implementing acts, considering the provisions related to the handling of findings as specified under point CAMO.B.350.
  • The Civil Aviation Authority (CAA) being granted access to the organisation as specified in point CAMO.A.140.
  • The certificate not being surrendered or revoked.

For air carriers licensed in accordance with UK Regulation (EC) No 1008/2008, termination, suspension or revocation of the air operator certificate automatically invalidates the organisation certificate in relation to the aircraft registrations specified in the air operator certificate, unless otherwise explicitly stated by the CAA.

Once granted, an approval requires a recommendation for continuation every 24 months (unless otherwise agreed) from the date of issue. This is raised by the CAA Surveyor following a satisfactory audit programme.
