The UK’s exit from the EU and EASA has changed engineering licensing requirements, particularly in relation to what licences are needed to certify a UK registered aircraft from the 1 January 2023.

Maintenance organisations and aircraft engineers are reminded that:

  • For a maintenance organisation based in the UK, certifying a UK registered aircraft, an EASA Part 66 licence is no longer acceptable.
  • For a maintenance organisation based in the UK, certifying a UK registered aircraft, an EASA Part 66 licence is no longer acceptable as the basis of a UK Part 145 maintenance organisation authorisation issued under UK.145.35 (b).
  • Organisations may continue to use EASA Part 66 staff within the EU if the supporting Part 145 qualifies them as per Appendix IV - to 145.A.30(j)(2)).

All Licensed Aircraft Engineers (Part 66) will be required to hold a CAA issued Part 66 Licence to continue to certify in the UK and maintain UK registered aircraft from 1 January 2023.

The applications window to transfer from EU to UK Part 66 closed on 31 December 2022.

Gaining a UK licence from 01 January 2023

If you previously held a UK issued Part 66 Licence, which was subsequently transferred to an EU member state prior to the UK EU Exit date, you can apply to reactivate your UK Part 66 licence.

All other applicants will need to follow the normal route to apply for a UK Part 66 aircraft maintenance licence.

Acceptance of EASA Part 147 Certificates of Recognition

The UK is unable to accept any EASA Part 147 Certificate of Recognition dated after 31st December 2022.

The end of the Withdrawal Agreement on this date, removed the legal basis for these certificates in the UK, therefore the CAA has no legal power to accept any certificated dated after this date.

Basic module and basic course certificates will continue to be accepted up to 10 years after their issue date, when issued before 31st December 2022.

Type rating certificates will continue to be accepted up to 3 years after their issue date, when issued before 31st December 2022.

Any certificate dated after 31st December 2022, must have been issued by a UK Part 147 Maintenance Training Organisation which can be found located internationally.

Air-Tech Bildung GmbH

The approval of the maintenance training organisation Air-Tech Bildung GmbH with the approval number DE.147.0014 was revoked by the German Federal Aviation Authority. Following the decision by the German Federal Aviation Authority to consider all certificates issued by Air-Tech Bildung in the years 2023 and 2024 as invalid. 

The UK CAA has no method of validating any certificates issued by Air-Tech Bildung therefore, the CAA is not able to accept these certificates in support of a licence application regardless of the date of issue.
