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.

UK regulations aligned British Civil Airworthiness Requirements (BCAR) Section A with European regulations in August 2012. The changes apply to aircraft excluded from Regulation (EU) 2018/1139 as retained (and amended in UK domestic law) under the European Union (Withdrawal) Act 2018 (the UK Basic Regulation), including those aircraft listed in Annex I, commonly referred to non-Part 21 aircraft.

Mandatory Requirements for Airworthiness (CAP 747) contains the list of non-Part 21 aircraft types. It also provides a statement of the general categories of aircraft that are excluded from the UK Basic Regulation and so remain subject to rules under The Air Navigation Order. These changes apply to non-Part 21 aircraft that operate on a Certificate of Airworthiness (C of A).

The Civil Aviation Authority (CAA) has determined that some aircraft types are required to meet Additional Requirements for Importation (ARIs) prior to the issue of a Certificate of Airworthiness (C of A).

The CAA issue a non-expiring C of A, National Airworthiness Review Certificate (National ARC) and noise certificate (if required) for each aircraft. After receipt of your non-expiring C of A and initial National ARC, the National ARC can be extended for two years, after which time a full airworthiness review will be required prior to a new National ARC being issued.

For a used non-Part 21 craft being imported into the UK a check flight is required to support the airworthiness review.


The recommendation for the initial issue of a National ARC may only be made by a BCAR A8-25 (CAMO) or an A8-15 (M3) organisation that holds appropriate approval for this purpose.

Non-military State aircraft, those used for commercial air transport, or public transport are to be managed by an A8-25 (CAMO) and maintained by an A8-23 (M1) organisation.

Remaining C of A aircraft may have their continuing airworthiness managed by an A8-25 (CAMO) or they can have an annual review performed by an A8-25 (CAMO). For those aircraft below 2730kg MTOW the annual review can also be carried out by an appropriately licensed engineer.

For aircraft below 2730kg MTOW, maintenance may be performed by an A8-23 (M1), A8-24 (M2) approved organisation or independent certifying staff.

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 prior to the issue of any Airworthiness Certificate.

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 owners / 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 BCAR Section A (A8-25 para 10 or A8-15 para 3) must be completed and a National ARC Issue Recommendation made for all aircraft imported from outside the UK prior to the issue of the Certificate of Airworthiness. This should be provided to the Civil Aviation Authority (CAA) prior to any survey.
