Supplemental Type Certificates

List of EASA Supplemental Type Certificates

The list of EASA Supplemental Type Certificates is available in the download section below. The list is updated on a weekly basis. The Agency applies its best efforts to ensure completeness of this list.

All EASA STCs are published except: 
- 'Grandfathered' STCs issued by the EU Member States prior to 29/09/2003.
- STCs issued by Switzerland (FOCA) prior to 2007

Currently, no central repository of grandfathered approvals is established.
To receive a copy of a grandfathered STC, please contact either the STC holder directly or review the websites of our member states’ national aviation authorities. A list of NAAs has been compiled in our FAQs.

The preferred way to receive your STC application is via the EASA Portal:

If you are not an EASA Portal user yet, please register by sending an email to portal [at]

Alternatively, the application form FO.CERT.00033 can be downloaded from our website.

For more detailed information, please consult our dedicated FAQs on STCs.
