Approval Process

There are three ways in which equipment may be granted approval:

1. A European Technical Standard Order Authorisation (ETSOA) applied through and granted by European Aviation Safety Agency (EASA).
2. A National Aviation Authority (NAA) approval, such as the CAA UK or a JTSO (Joint Technical Standard Order).
3. Approval at the aircraft level as part of the Type Certificate or change to it (Supplemental Type Certificate, major/minor change).

Notes on the approval process:
- ETSOA or NAA equipment approval does not infer any approval to install onto an aircraft.
- JTSOs and NAA equipment approvals issued prior to 28 September 2003 are equivalent to ETSOA.
- NAA equipment approvals issued since 28 September 2003 are only valid for use on non-EASA aircraft.

Information on how to apply for a equipment approval can be found on the EASA website or by contacting the CAA as addressed below:
