• Pre-Requisites

    Organisations should have their principal place of business in the UK.  

    Organisations with their principal place of business located outside the UK, including those based in the Channel Islands, should apply directly to EASA.

    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.

    If adding an aircraft which falls within a generic aircraft group that you already hold on your approval certificate (e.g. Piston engine aeroplanes – metal structure not exceeding 5700 kg) then you should email an exposition amendment to apply@caa.co.uk or attach/upload the draft exposition to the online application form (where applicable). Please do not send to your surveyor directly as it will delay your application processing.

  • How much does it cost?

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

    If you apply for an initial approval with multiple ratings under the same approval type, you must include a payment relating to the charge for the highest rating applied for e.g. a Part 145 application for ratings A2, A3 and B1 would attract a single charge for the highest rating, being the B1, as per the 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.

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

    • When the Organisation Approvals team receive the recommendation the approval certificates will be raised and sent to your organisation within 20 working days

    How long is it valid for?

    • Once granted a Part 145 approval requires a recommendation for continuation every 24 months from date of initial issue. This is raised by the CAA Surveyor following a satisfactory audit programme.
    • A completed application form submitted by an Authorised Representative of the Company e.g. the proposed Accountable Manager.

       (Aircraft ratings should be listed as per  EASA Part-66 Appendix 1 listing. At this time the Part 66 listing does not include Sailplanes, Powered Sailplanes or Balloons.  In this case use the aircraft type designation specified on the Type Certificate Data Sheet.) 
       
    • A minimum of one  EASA Form 4 for key personnel i.e. Quality Manager. Additional Form 4's may be requested by your allocated CAA surveyor. Please ensure that the CAA policy on fitness of character is fully understood before submission of an application. Additional Form 4's may be requested by your allocated CAA surveyor.
