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 British Civil Airworthiness Requirements (BCAR), Section A3-7 (CAP 553). Aircraft in this category are generally ex-military, amateur built, microlight, gyroplanes or without a valid Type Certificate.

"Permit to Fly Aircraft" (CAP 733) 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 first issue of an aircraft's permit to fly.

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

Make an application

The below information offers advice on how to make an application:

Permanent permits to fly

A permanent permit to fly may be issued in accordance with Subpart P of UK Regulation (EU) No. 748/2012 for non-commercial flying activity on individual, non-complex Part 21 aircraft types for which a Certificate of Airworthiness or Restricted Certificate of Airworthiness is not appropriate.

The Civil Aviation Authority (CAA) may issue a National permit to fly for non-Part 21 aircraft types in accordance with BCAR A3-7, only to aircraft that are not eligible for a National Certificate of Airworthiness.

Close Permanent permits to fly

Temporary permits to fly

A temporary permit to fly is issued in accordance with Subpart P of UK Regulation (EU) No. 748/2012 when a Part-21 aircraft is temporarily unable to comply with the regulations set for the issue of a Certificate of Airworthiness or Restricted Certificate of Airworthiness but is still capable of safe flight under defined conditions. They may also be issued to a Part-21 aircraft that usually holds a 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 in accordance with BCAR to a non-Part 21 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 to fly aircraft, decided that this condition should be withdrawn for aeroplanes in certain categories.
