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    As a result of this increase in overall volumes, we have recently withdrawn the same day/fast track application process for all applications other than: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


  • Application guidance

    You can get a Certificate of Airworthiness for National (Annex II) that meet the certification standards required.

    To find out which aircraft may be eligible for a National C of A, see CAP 747. State Aircraft (e.g. police, Search and Rescue) are only eligible for a National C of A according to EC regulation 216/2008, Article 1 para 2.

    Certificate of Airworthiness (C of A) Issue refers to the validation of an aircraft’s first C of A.

    A C of A Subsequent Issue is applicable when:

    • The previous UK C of A has been revoked or surrendered
    • The aircraft held a UK C of A prior to export and has since returned to the UK Register
    • The aircraft was removed from, and has since been re-registered on, the UK Register
    • The aircraft's current Certificate of Airworthiness has expired and a non-expiring Certificate of Airworthiness has yet to be issued

    Who can apply

    • Registered Aircraft Owners
    • Aircraft Operators
    • Continuing Airworthiness Maintenance Organisations (CAMOs)
    • Maintenance Organisations

    How to apply

    Additional resources

  • Unmanned Aerial Vehicles (UAVs)

    Some will require a C of A. Applications are dealt with by contacting UAVenquiries@caa.co.uk.

    Hang gliders, foot-launched powered hang gliders, paragliders and single seat microlights.

    Although it is mandatory to comply with the Rules of the Air, hang gliders, foot launched power gliders, paragliders and registered single seat microlights (SSDRs below 300kg) are not required to hold a C of A or Permit to Fly.

    Non-EASA balloons

    Privately operated non-EASA balloons are not eligible for a C of A under ANO Article 16. Please contact apply@caa.co.uk if you require further guidance.
