The Government will be publishing all UK aviation law (including retained EU law) on in due course.

Aviation Law from 1 January 2021

When the UK was a member of the European Union some aviation law was made by the European Union and had direct legal effect, as a European Regulation, in the UK.

The UK has now fully left the European Union, after the end of the UK/EU Agreement transitional period.

From 1 January 2021 the UK law that applies to such aviation rights and obligations are the retained EU Regulations, as amended by various UK Statutory Instruments (made under the European Union (Withdrawal) Act 2018).

The amendments that apply from 1 January 2021 do not fundamentally change any of those obligations or rights but deal only with the fact that the UK is no longer part of the EU legal system.

Some EU aviation law was accompanied by Acceptable Means of Compliance (AMC), Guidance Material (GM), Certification Specifications (CS) or other information published by EASA. The CAA has adopted the version of AMC, GM, CSs and other information in force on 31 December 2020, as its policy with regard to compliance with the relevant UK law from 1 January.
