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.



In accordance with Regulation (EU) No 748/2012, as retained (and amended in UK domestic law) under the European Union (Withdrawal) Act 2018, all UK Part 21 aircraft types that qualify for a Part 21 Certificate of Airworthiness (C of A) are issued with a non-expiring C of A, validated annually with an Airworthiness Review Certificate (ARC). This annual validation will be either the issue of a new ARC or an Extension of the validity of the current ARC.

The Civil Aviation Authority (CAA) has determined that some aircraft types are required to meet Additional Requirements for Importation (ARI) before a Certificate of Airworthiness can be issued.

If a concession is required, please advise the Shared Service Centre when you apply.

There are currently two methods by which a Part 21 Certificate of Airworthiness and ARC can be issued.

  • Surveyor Involvement (details provided below under 'What to Expect').
  • Direct / Indirect Issue (details provided below under 'What to Expect').

For used aircraft being imported into the UK, a check flight is required to support the airworthiness review.

Please note: The term Certificate of Airworthiness in the context of this information include aircraft that qualify for a ‘Restricted Certificate of Airworthiness’ (R C of A).

Prerequisites

In order to successfully make an application you must provide:

  • details of the aircraft
  • approved organisation details
  • location of the aircraft for survey (if required)

Please note: The aircraft must be registered in the UK before any Airworthiness Certificate can be issued.

As required by UK Reg (EU) No 1079/2012 (the UK Voice Channel Spacing Regulation), all new aircraft issued with an individual Certificate of Airworthiness after 17 November 2013, which have VHF radios fitted, are required to have a radio with an 8.33KHz channel spacing. It is the owner's/operator's responsibility to ensure that the aircraft is appropriately equipped with such a radio.

What else do I need to know?

A Satisfactory Airworthiness Review in accordance with (UK) Part M (M.A.710) must be completed and a Recommendation for an ARC issue made for all used aircraft before the Certificate of Airworthiness can be issued. This should be provided to the Civil Aviation Authority (CAA) before any survey.

Any new aircraft which has been imported into the UK with a Part 21 Form 52 or Export Certificate of Airworthiness which has not had the UK Certificate of Airworthiness issued within 60 days of import will require a Satisfactory Airworthiness Review in accordance with (UK) Part M (M.A.710) and a Recommendation for an ARC issue made. This should be provided to the CAA before any survey.

What happens next?

C of A Issue/Subsequent Issue - Surveyor Involvement

  • Complete the C of A Online Form and pay the applicable fee online.
  • The application will be passed to the Technical Section for review.
  • Further information to substantiate the application may be required - the Maintenance Organisation or CAMO will usually be the contact for this information.
  • Upon successful review of the application, it will be determined if Surveyor Involvement is required (advice will be given if the application is to be processed as a Direct/Indirect Issue).
  • The Resource Scheduling team will arrange for the Regional Office Surveyor to survey the aircraft.
  • A Certificate of Airworthiness, Airworthiness Review Certificate and Noise Certificate (if applicable) will be issued once the Regional Office Surveyor is satisfied that all necessary paperwork is in order and that the aircraft is airworthy.

C of A Issue - Direct/Indirect Issue

A Direct Issue can only be considered for a new aircraft that has not yet moved from the manufacturer. An indirect issue can only be considered for newly manufactured non-complex aircraft types excluding multi-engine helicopters.

A lead time of at least four weeks' notice is required. Direct/Indirect Issue is carried out at the discretion of the Civil Aviation Authority (CAA). If you believe a Direct/Indirect Issue may be possible, please contact the Shared Service Centre to discuss this in further detail. The CAA reserves the right to revert any application to 'Surveyor Involvement' at their discretion.

To apply for the issue of a Part 21 Certificate of Airworthiness using the Direct/Indirect Issue process:

  • Complete the C of A Online Form and pay the applicable fee online and acceptable transfer documentation/confirm the acceptable transfer documentation that will be available.
  • The application will be passed to a Technical Standards Surveyor in the Technical Section for review.
  • Further information may be required to substantiate the application, the Maintenance Organisation or CAMO will usually be the contact for this information.

At this stage it may be identified that the application may be considered for a Direct Issue.

  • If a Direct Issue is agreed, the technical section will liaise with the manufacturer and applicant to organise the delivery of certificates and other relevant paperwork to the manufacturer.
  • At the time of delivery, the manufacturer issues the relevant certificates and forwards all required paperwork to the technical section.
  • If an indirect issue is agreed, the technical section will liaise with the maintenance organisation or CAMO to organise receipt of all relevant, required paperwork.
  • At the time of registration and receipt of the above, the C of A, ARC and noise certificate (if required) will be forwarded to the registered owner.

We cannot accept an aircraft for Direct/Indirect Issue if any of the following are applicable:

  • the aircraft is designated as a "first of type"
  • the aircraft moves for finishing - i.e., away from the manufacturer's factory facility
  • there are derogations/exceptions to the aircraft UK Part 21 Type Certificate Data Sheet (TCDS) or unapproved modifications or Supplemental Type Certificates (STCs)
