• Please visit the CAA's EU exit microsite for information and guidance relating to UK’s exit from the European Union. 

    As part of this preparation, the CAA will now accept third country applications from organisations with their principal place of business located outside the UK, (including EU countries, Channel Islands and rest of the world) for airworthiness approvals:

    • Part M Subpart F Maintenance Organisation - MO
    • Part M Subpart G Continuing Airworthiness Maintenance Organisation - САМО
    • Part 145 Maintenance Organisation Approvals - MOA
    • Part 147 Maintenance Training Organisation Approvals - MTOA


    Who should apply?

    Organisations with their principal place of business located outside the UK, (including the EU Countries, Channel Islands and rest of the world), that wish to carry out production, maintenance or manage continuing airworthiness of aircraft and/or components that are used for UK-registered aircraft.

    Organisations needing to change a Registered Company or Limited Liability Partnership (LLP) Number will require a new initial approval as it cannot be classed as a change to an existing approval. See CAP 562, Leaflet C-30 for further information.  

    How much does it cost?

    See the Official Record Series 5, CAA Scheme of Charges.

    In the event of a discrepancy between the information here and the Official Record Series 5, CAA Scheme of Charges (Airworthiness, Noise Certification and Aircraft and Aircraft Engine Emissions), the Scheme of Charges takes precedence.

    If the number of hours taken by the CAA to carry out its investigations in relation to the application exceeds the cost shown above, the applicant must pay an excess hourly charge. The CAA shall determine the excess hourly charge by taking the total number of excess hours taken by the CAA to complete the required investigations in relation to the application and multiplying that number of hours by an hourly charge. The balance for the excess hourly charge (total hourly charge less initial charge already paid) is payable by the applicant to the CAA and will be invoiced to the applicant.

    Payments can be made by credit or debit card or by bank transfer. When using bank transfer, please identify what the payment is for by including your approval reference and receiving department.

    How long will it take for my application to be processed?

    You will receive an automated email receipt for your online application. Once your application has been processed and payment taken, a surveyor will contact you to discuss the next steps and timeframes which you can expect. No approval certificate can be issued prior to the UK’s formal withdrawal from the EU on the 29th March 2019.

    How long is it valid for?

    • Approvals remain valid unless cancelled, suspended or revoked.
    • Once granted, an approval requires a recommendation for continuation every 24 months from the date of issue. This is raised by the CAA Surveyor following the completion of a satisfactory audit programme.

    What else do I need to know?

    • The application form must be submitted by an authorised representative of the company. 
    • Official Record Series 5, CAA  Scheme of Charges
