General validation for EU pilots

Under ICAO rules, a pilot wishing to operate an aircraft which has a different State of Registry to the state that issued that pilot’s licence must have a validation from the relevant authorities.

This means that flight crew carrying a non-UK CAA licence, issued by an EASA Member State, who operate UK-registered aircraft must carry a ‘general validation’ with their licence. This is issued by the UK CAA. This is available here for download:

The general validations are valid for two years under UK law.


General validation for Swiss pilots

Under ICAO rules, a pilot wishing to operate an aircraft which has a different State of Registry to the state that issued that pilot’s licence must have a validation from the relevant authorities.

This means that flight crew carrying a non-UK CAA licence, issued by Switzerland, who operate UK-registered aircraft must carry a ‘general validation’ with their licence. This is issued by the UK CAA. This is available here for download: 

The general validations are valid for two years under UK law.


Validation of airworthiness certificates – all UK-registered aircraft

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. We have also communicated to all National Aviation Authorities the legal basis for this decision. The letter is available here:


General Validation for former UK Part FCL holders awaiting EASA Part FCL licences

The CAA understands that there are a number of pilots who transferred their licences to an EASA Member State before 31 December 2020, who are still waiting the issue of their EASA Flight Crew Licence. To allow these pilots to continue operating UK-registered aircraft, the CAA has issued a Validation to grant such pilots who obtain their EASA licence between 1 January 2021 and 31 March 2021.

Individuals wishing to take advantage of this validation should download the document on the link below and complete the information as to their previous UK Flight Crew Licence number.

This validation is valid until 31 December 2021.


Validity of licence and medical issued by the United Kingdom

The CAA has produced a guidance document to support UK pilots during ramp inspections. The document explains and confirms the validity of UK pilots carrying EASA format licence and medical documents, and is available here:


Recognition of Continuing Airworthiness Management Organisations

The CAA will continue to accept Continued Airworthiness Management Organisations (CAMO) with an EASA Part M Subpart G, Part-CAMO, or Part-CAO approval, which have their principal place of business located outside the UK, to manage UK registered aircraft and to issue or extend the validity of their Airworthiness Review Certificates, as if their privileges and approvals were issued by the CAA.

This letter is valid until 31 December 2022 and is available here:
