UK Civil Aviation Regulations

These are published by the CAA on our UK Regulations pages. EU Regulations and EASA Access Guides published by EASA no longer apply in the UK. Our website and publications are being reviewed to update all references. Any references to EU law and EASA Access guides should be disregarded and where applicable the equivalent UK versions referred to instead.



European Union

The trade and cooperation agreement between the EU and the UK addresses aviation safety at Article AIRTRN.18.

The UK Civil Aviation Authority (CAA) and EASA have concluded negotiations on the Technical Implementation Procedures (the TIP), which was signed at a ceremony on 17 May 2021.

Approvals covering design and production of civil aeronautical products

UK-EU Airworthiness and Environment Certification: Draft Design Certification

Existing design certificates status

The UK-EU Trade and Cooperation Agreement recognises:

  • type certificates,
  • supplemental type certificates,
  • approvals for changes and repairs, and
  • technical standard order authorisations

issued by EASA or an EASA approved design organisation that were valid on 31 December 2020.

These are considered to be accepted by EASA and the Civil Aviation Authority (CAA) in accordance with ANNEX AVSAF-1 AIRWORTHINESS AND ENVIRONMENT CERTIFICATION, Article 15.

Design changes

The UK-EU Trade and Cooperation Agreement states that minor changes and minor repairs approved by CAA or a CAA approved design organisation are accepted by EASA and vice versa.

Further details can be found in ANNEX AVSAF-1 AIRWORTHINESS AND ENVIRONMENT CERTIFICATION, Article 13

EASA approved design changes

The UK-EU Trade and Cooperation Agreement states that:

  • non-significant supplemental type certificates
  • non-significant major changes
  • repairs and technical standard order authorisations

Issued by EASA or an EASA approved design organisation will be accepted by CAA. Further clarification on classification will be provided in the CAA/EASA TIP.

Further details can be found in ANNEX AVSAF-1 AIRWORTHINESS AND ENVIRONMENT CERTIFICATION, Article 13.

CAA approved design changes

The UK-EU Trade and Cooperation Agreement states that:

  • type certificates
  • supplemental type certificates
  • approvals for major changes
  • major repairs and technical standard order authorisations

Issued by CAA or by a CAA approved design organisation will not be directly accepted by EASA and will be subject to technical validation by EASA. In some cases, when agreed by CAA and EASA, a streamlined validation may be performed.

Further details can be found in ANNEX AVSAF-1 AIRWORTHINESS AND ENVIRONMENT CERTIFICATION, Article 10.

Technical validation of EASA approved design changes

The UK-EU Trade and Cooperation Agreement states that:

  • type certificates
  • significant supplemental type certificates
  • approvals for significant major changes

Will be subject to either technical validation or streamlined validation by CAA. Further clarification on classification and corresponding validation path will be provided in the CAA/EASA TIP.

Further details can be found in ANNEX AVSAF-1 AIRWORTHINESS AND ENVIRONMENT CERTIFICATION, Article 10.

UK-EU Airworthiness and Environment Certification: Production

EASA Production Organisation Approval (POA) (as Third Country Approval) for UK goods to be accepted in the EU

The UK-EU Trade and Cooperation Agreement (TCA) enables the EU to recognise the POA issued by the UK Civil Aviation Authority (CAA) for categories of products that are already approved for production on 31 December 2020.

UK POA for EU goods to be accepted in the UK

The UK-EU Trade and Cooperation Agreement enables the UK to recognise the POA issued by the European Aviation Safety Agency (EASA) CAA for categories of products that are already approved for production on 31 December 2020.

Export to the EU

The UK-EU Trade and Cooperation Agreement recognises the CAA Form-1 for the export of new parts, appliances, engines and propellers and CAA Form 52 for the export of new complete aircraft.

Therefore, there is no need for UK-based organisations to hold an EASA Third Country POA. Consequently, EASA has not issued any Third Country POA to organisations in the UK and as such, there are no EASA.UK.21G.XXXX approvals.

Export to the UK

In the UK-EU Trade and Cooperation Agreement the UK recognises the EASA Form 1 for the export of new parts, appliances, engines and propellers and EASA Form 52 for the export of new complete aircraft.

Therefore, there is no need for an EU based organisation to hold a UK POA.

Close UK-EU Airworthiness and Environment Certification: Production

Products, parts and appliances that are covered by the acceptance of the production system under the agreement between the EU and the UK

As per the Trade and Cooperation Agreement (TCA) between UK and EU, in particular Art 21 of ANNEX AVSAF-1, the production of all categories of civil aeronautical products that were produced on December 31, 2020 in the EU and the UK, respectively, are mutually accepted.

Annex AVSAF-1 further determines that these categories are to be defined in the related Technical Implementation Procedures (TIP).
