UK – EU Transition, and UK Civil Aviation Regulations

To access current UK civil aviation regulations, including AMC and GM, CAA regulatory documents, please use this link to UK Regulation. Please note, if you use information and guidance under the Headings below, the references to EU regulations or EU websites in our guidance will not be an accurate information or description of your obligations under UK law. These pages are undergoing reviews and updates.


  • Organisations should have their principal place of business in the UK
  • Organisations with their principal place of business located outside the UK should apply for a UK Third Country Approval.

Organisations needing to change a Registered Company or Limited Liability Partnership (LLP) Number will require a new initial approval as it cannot be classed as a change to an existing approval.

See CAP 562, Leaflet C-30 for further information.

How much does it cost?

See the Official Record Series 5, CAA Scheme of Charges.

If you apply for an initial approval with multiple ratings under the same approval type, you must include a payment relating to the charge for the highest rating applied for e.g. a Part 147 application for ratings T1, T2 and C would attract a single charge for the highest rating, being the T1, as per the Scheme of Charges.

In the event of a discrepancy between the information here and the Official Record Series 5, CAA Scheme of Charges (Airworthiness, Noise Certification and Aircraft and Aircraft Engine Emissions), the Scheme of Charges takes precedence.

How long will it take for my application to be processed?

  • When the Organisation Approvals team receive the recommendation from Airworthiness confirming the organisation has achieved the required standard, the approval certificates will be raised and sent to your organisation within 20 working days.

How long is it valid for?

  • Once granted a Part 147 approval requires a recommendation for continuation every 24 months from date of initial issue. This is raised by the CAA Surveyor following a satisfactory audit programme.

What else do I need to know?

  • Continuing Airworthiness Regulation (EU) No 1321/2014 as retained (and amended in UK domestic law) under the European Union (Withdrawal) Act 2018
  • CAP 562 - Leaflet C-30 - 'CAA Approvals - Non-Transferability'
  • CAP 1528 - Guidance for Part 147 Instructors
  • CAP 1529 - Aircraft maintenance type practical training within a UK Part 147 Organisation
  • UK regulations
  • Guidance for Part 147 holders
