|The CAA will continue to accept references, including EASA form numbers, to any EU regulation which are cited on documents carried by UK-registered aircraft. This includes Certificates of Airworthiness (CofA), Airworthiness Review Certificates (ARC) and Noise Certificates. These will remain valid until they are renewed, whereby they will be replaced with CAA references and form numbers.|
To minimise the risk of disruption, we are making available a letter available to all operators confirming the validity of these documents for carriage on UK aircraft. This letter should be carried onboard the aircraft at all times. The letter is available here.
