• Pre-requisites

    • Organisations should have their principal place of business in the UK
      Organisations with their principal place of business outside the UK, including those based in the Channel Islands, should apply directly to EASA.
    • Regulation (EU)1321/2014 details the rules for the continuing airworthiness and maintenance of aircraft subject to European regulation (EASA aircraft).
    • Part-145 of this Regulation concerns the maintenance of EASA aircraft and components used for commercial air transport purposes as well as those defined by this regulation as ‘Large 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.

    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 supply an exposition amendment directly to your surveyor. No fee or application form is required.

  • You can complete the remove ratings and facilities form  provided that these are the only changes you are making to the approval. There is no charge for this service but you will need to provide a copy of your amended exposition

    To add or remove temporary or permanent Line Stations (Line Maintenance Facilities) to/from an existing approval, please use CAA Form SRG 1761.

    SRG 1761 is not required for Occasional Line Maintenance (less than ten consecutive days).                     

    For further information, please refer to:

    This sets out how Part-145 organisations may establish temporary line stations in accordance with approved procedures. This will enable the CAA to plan its oversight accordingly.

    The Information Notice also includes information to clarify:

    • the difference between occasional line maintenance and a temporary line station
    • how organisations may establish a temporary line station without requiring a CAA Surveyor to audit the location prior to maintenance commencing

    In cases where an organisation holds more than one approval and requires to make an application for a change of address which will affect each approval held, you can complete the change of address form which will cater for both BCAR and EASA approvals. (You will need to provide a copy of your amended expositions).

    Changes to the key personnel in an organisation must be notified to CAA. You can add or remove/change the details of one or several people, including identifying their role(s) and the types of approval(s) they have responsibility for, by completing the  Change of Accountable Manager or Nominated Postholder form. This form caters for both EASA approvals as well as BCAR (national) approvals. There is no charge for changes of personnel. 

    Please note that for changes of Nominated Postholders, a  Form 4 (SRG1705) will need to be completed and attached to the application.

    To help us progress your application please send a copy of your draft exposition to apply@caa.co.uk or advise if you have already supplied the information to your surveyor.
