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, 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.

Processing times for aircraft certification applications

We are seeing an increase in aircraft certification applications (Certificate of Airworthiness, Temporary Permit to Fly and Flight Conditions), due to EU exit and Covid-19 pandemic business continuity planning.

This has presented challenges with meeting the service level agreement of twenty days (five days for Temporary PtF applications) for processing each application, before it is passed on to an available airworthiness surveyor to carry out any required oversight, and the certificate can be issued to the applicant.

We have allocated additional resource to process the application backlog as quickly as possible.

As a result of this increase in overall volumes, we have recently withdrawn the same day/fast track application process for all applications other than:

  • Temporary Permit to Fly – for an AOC AOG aircraft or a State aircraft only
  • Overflight Permission – for operational aircraft only

Applications are being processed in the order that they are received and we are unable to accommodate expedite requests.

While we aim to meet or improve on our service level agreement, however this depends on applications containing all of the required information.

Incomplete applications will result in the possible rejection or the application being put ‘on hold’ due to missing data. This will result in additional time to process the application and the issuing of the required licence or approval certificate.

Is your aircraft grounded outside our working hours? UK AOC holders can call +44(0) 330 022 1500 for emergency operational advice.

Application guidance

A permit to fly may be issued to aircraft that do not meet the International Civil Aviation Organisation (ICAO) certification standards required for the issue of a Certificate of Airworthiness (C of A) subject to satisfying certain requirements.

A permit to fly will not be issued to an aircraft that is eligible for the issue of a C of A, but may be issued in the event of a C of A becoming temporarily invalid.

A National permit to fly is granted, in accordance with BCAR A3-7. Aircraft in this category are generally ex-military, amateur built, microlight, gyroplanes or without a valid Type Certificate.

CAP 733 - "Permit to Fly Aircraft" is a comprehensive source of information regarding Permits to Fly and provides guidance on the following topics:

  • Qualifying for the initial issue of a permit to fly
  • Criteria for the issue of a permit to fly
  • Modifying or repairing a permit to fly aircraft
  • Maintenance inspection and revalidation of an aircraft issued with a permit to fly
  • Operation of a permit to fly aircraft
  • A permit to fly issue refers to the validation of an aircraft's first permit to fly
  • A permit to fly renewal is applicable when the permit to fly expires

A permit to fly issue refers to the validation of an aircraft's first permit to fly.

A permit to fly renewal is applicable when the permit to fly certificate of validity expires.

Permanent permits to fly

An EASA permanent permit to fly may be issued for non-commercial flying activity on individual, non complex aircraft types for which a Certificate of Airworthiness or Restricted Certificate of Airworthiness is not appropriate.

The CAA may issue a National permit to fly in accordance with BCAR A3-7, only to aircraft that are not eligible for a National Certificate of Airworthiness.

Temporary permits to fly

An EASA temporary permit to fly is issued when an aircraft is temporarily unable to comply with the regulations set for the issue of a Certificate of Airworthiness but is still capable of safe flight under defined conditions. They may also be issued to an EASA aircraft that usually holds a EASA permanent permit to fly, but this has expired and the aircraft requires either a check flight or a positioning flight.

A temporary National permit to fly is issued to a national aircraft type to allow the aircraft to complete a check flight or positioning flight (when ‘A Conditions’ are not applicable).

The standard permit to fly issued by the CAA includes a condition prohibiting flight over the congested area of a city, town or settlement. The CAA has, after careful consideration of the levels of safety achieved for certain categories of permit aircraft, decided that this condition should be withdrawn for aeroplanes in certain categories.
