Automatic acceptance of changes and repairs is possible if they are in compliance with the EASA Executive Director Decisions in force with the respective country.
If approval of a change or repair is required, please refer to the “Distribution of Tasks”, in order to address the application to the correct institution.
These notes are intended to provide guidance to anyone considering applying for an Austrian Certificate of Airworthiness for an aircraft imported from outside the European Union (EU) that incorporates modifications or repairs not previously approved by EASA.
Background to Changes
Annex to Regulation (EC) No 1702/2003 (Part 21) specifies the requirements for approving modifications ("changes"). Any modification approved by any of the EU member states before 28th September 2003 is deemed approved by EASA, and will not need to be technically investigated again, if it is not restricted to a certain serial number range, where the applicable product would not be affected. Please note, however, that responsibility rests with the applicant to demonstrate the approval status when applying for a Certificate of Airworthiness.
Under EASA, aircraft owners can still apply for the issue of a Certificate of Airworthiness, but can no longer apply for approval of major modifications (this includes modifications where design approval is via FAA Forms 337 and 8110-3)).
Modifications embodied on an aircraft registered in an EU member state must be approved in accordance with EU Regulation (EC) No 1702/2003. This also applies to aircraft joining the register of an EU member state from outside the EU after this date.
EASA approval can be achieved via the following routes:
Application for EASA approval should be made to EASA (and anyone from within the EU can apply) - https://www.easa.europa.eu/easa-and-you/general-aviation/documents-guidance-and-examples.
Alternatively, a Design Organisation appropriately approved in accordance with Annex to Regulation (EC) No 1702/2003, Part 21 Subpart J can approve it directly.
The recognition of changes/repairs approved by the FAA, TCCA or ENAC Brazil is detailed in the application bilateral agreement.
