FAQ n.19368

How do I apply for an STC approval?

Answer

Application for STCs are made using the specific form available in the Application forms page.

Applications can be ot two types:

  1. An application from an EU organization for the EASA approval of a new STC. This requires theat the applicant has Design Organisation Approval (DOA) or, at least, Alternative Procedures (AP to DOA).
  2. An application from a non-EU organization for the EASA validation of a non-EU STC. The application must be made in accordance with any Working Arrangement or Bilateral agreement. In the case of STCs issued by the FAA, for example, the STC holder must make the applicaion via the FAA Aircraft Certification Office (ACO) that did the original approval.
