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.



We are committed to making informed and careful decisions about the people and organisations we regulate. However, if you have a concern that we have not followed the correct process in coming to a regulatory decision that has affected you, you may ask us to undertake a review.

You can ask us to carry out an internal review of our decision. This will be handled by someone independent of the original decision.

Not all decisions can be reviewed.

If, having followed the internal stage of the review process, you are not satisfied, you can request a referral to the Independent Review Panel (IRP) who are independent of the Civil Aviation Authority (CAA).

Decisions that are in scope for an internal review which has been explained previously, may also be reviewed by the IRP following the outcome of the internal review, if they meet certain eligibility criteria.

The IRP may choose not to consider your case based on the information you provided.

Eligible decisions must be those previously mentioned and be taken after the 2 May 2022.

Regulation 6

There is another option available if you are dissatisfied with a decision we have reached but do not want to pursue it through the Independent Review Panel.

The Regulation 6 process may be more appropriate for your circumstances.

Overview of Regulations 6



The Regulation 6 review process is established by Regulation 6 of the Civil Aviation Authority Regulations 1991. When a review is requested, a review panel is established to hear that matter comprising of CAA Non-Executive Board Members who are appointed by the Secretary of State and have had no previous involvement in the case.

The Regulation 6 review panel makes the regulatory decision on behalf of the CAA. This means it can review both the processes which were followed, as well as any substantial judgments made in a case.

Decisions in scope for review

The functions (both in UK as well as retained EU law) which are currently eligible for review are:

  • Registration of aircraft.
  • Certification of operators of aircraft.
Certification of airworthiness of aircraft.
  • Noise certification.
  • Certification of compliance with the requirements for the emission by aircraft engines of unburned hydrocarbons.
  • Personnel licensing.
  • Licensing of aerodromes.
Validation of any certificate or licence.
  • Approval of equipment and approval or authorisation of persons.
  • Approval of schemes for the regulation of the flight times of aircraft crew.
  • Receiving reports of reportable occurrences.
  • Making air traffic directions.
  • Making airspace policy directions.

Provisional suspension cases are not permitted to be reviewed through the Regulation 6 process.

Eligibility

On request (within 14 days of proposed decision), depending on whether it is a function which is listed in Regulation 6 of the Civil Aviation Authority Regulations 1991 as being able to utilise the Regulation 6 process (as listed on this page). There is no cost to the applicant in seeking a Regulation 6 review.

Estimated time of review

Variable depending on the availability of the parties, including those who constitute the review panel.

Further options

If a person is unsatisfied with the outcome of the Regulation 6 process, they are not permitted to request the case be considered by the IRP. Instead, they can appeal to the County Court in cases where fitness of character is an issue.

For all other cases, they can apply for a Judicial Review of the matter through the Administrative Court.
