Related information

The purpose of this consultation is to seek views on our proposals to update the UK Regulation (EU) No. 1321/2014 Continuing Airworthiness requirements for maintenance licences and training organisations.

The proposed amendments are set out in the accompanying three documents:

  • Proposed amendments to Annex III Part-66
  • Proposed amendments to Annex IV Part-147
  • Proposed amendments to Annex I Part-M, Annex II Part-145, Annex Vb Part-ML and Annex Vd Part-CAO

Regulations (also known as Implementing Rules)

Regulations contain requirements which must be complied with. The CAA’s statutory role is to consider the required content of regulations, consult on our proposed changes to the regulations, take consultation responses into account before forming a final view and then communicate that view to the Secretary of State (Department for Transport) in the form of an Opinion. Our Opinions are published. The Secretary of State makes the final decision whether to implement CAA’s proposed changes to the regulations, and the final wording of the regulations. The proposed wording of the regulations in this consultation may well change if and when the Secretary of State decides to amend the regulations.

Acceptable Means of Compliance (AMC) and Guidance Material (GM)

AMC are means by which the requirements in the Implementing Rule and the Essential Requirements of the Basic Regulation to which it relates could be met.

GM is non-binding and provides explanatory and interpretation material on how to achieve the requirements in the law and the AMC. It contains information, including examples, to assist the applicant with the interpretation of the legislative provisions.

Prior consultations

The CAA previously consulted on changes to Part-66 and Part-147 changes for E Propulsion Requirements under Rulemaking Task (RMT) 0134 in February 2024. As a result of the consultation responses, the proposed amendments for electric propulsion are now revised under this rulemaking task, RMT 0201. This rulemaking task can be found on the CAA Safety policy and legislation project tracker under Part-66 and Part-147 Regulation Rule and Associated AMC and GM Change.
