Update to CAP 747 ‘Mandatory Requirements for Airworthiness’

Issue 4 of CAP 747 ‘Mandatory Requirements for Airworthiness’ has been published to reflect the fact that the UK leaves the European Union aviation system at 23.00 on 31 December 2020 and the CAA will no longer be a member of the European Union Aviation Safety Agency (EASA).

As a result, the CAA will take on State of Design responsibilities from EASA for products where the UK is State of Design. The CAA will be responsible for fulfilling the UK’s obligations as State of Design or Manufacture as specified in Annex 8 of the ICAO Convention on International Civil Aviation.

Section 1, Part 1 of CAP 747 provides new flowcharts to assist in identifying the applicable mandatory requirements for airworthiness relating to your product. The revision history in CAP 747 provides more details.

CAP 747 is available to download from the CAA website.
