Acceptable Means of Compliance & Guidance Material to UK Regulation (EU) 1321/2014: Recognition of the EASA Form 1

For comments on the proposal that the CAA continues its existing policy to recognise certain EASA Form 1s as equivalent to CAA Form 1s in certain limited circumstances.

We also proposed AMC to give effect to the intention of working arrangements and to enable the CAA to permit the installation on UK registered aircraft of components maintained by approved organisations based in the state of signatory national aviation authorities.

We received 18 responses.

We received clear support for the CAA to take steps to make clear which components released on an EASA form 1 are acceptable to be fitted on a UK registered aircraft and when components cannot be.  You said that this clarity could best be achieved by making acceptability determined by the date of the EASA Form 1.    

We also received comments relating to the potential absence of parts in the UK that will be acceptable to be fitted on UK registered aircraft after 31 December 2022 for ELA1 aircraft. You said this was a risk due to European organisations not seeking CAA approval.

We received no comments on the wording to give effect to the intention of signed working arrangements with other national aviation authorities.

We have decided to adopt new AMC to UK (EU) Regulation 1321/2014 (the UK Continuing Airworthiness Regulation) that is simple to understand and easy to comply with that enables:

• Components released on an EASA From 1 prior to 1 January 2023 to be fitted to a UK registered aircraft
• Components released by an organisation based in a state with which the CAA has a working arrangement (which includes maintained parts) to be fitted to a UK registered aircraft; and
• Provided that the component is not available from a CAA approved organisation, a maintenance organisation in a state with which the UK has a bilateral safety agreement, or an organisation based in a state with whose NAA the CAA has a working arrangement, components of Part ML aircraft released on an EASA Form 1 by the component’s OEM to be fitted to a UK registered aircraft.

We have also decided to publish GM to UK (EU) Regulation 1321/2014 (the UK Continuing Airworthiness Regulation) to make clear that if a part released on an EASA Form 1 does not benefit from the newly adopted Part ML AMC referred to above, and so cannot be fitted to a Part ML UK registered aircraft, the relevant process that must be followed is AMC1 to Part CAO.A.070(a)(2.8) or AMC 2 to Part 145.A.50(d) paragraph (2.8) respectively.
