List of EASA Supplemental Type Certificates
The Agency applies its best efforts to ensure completeness of this list. The list is updated on a weekly basis.
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.
- What are grandfathered approvals?
- How do I know whether an FAA / TCCA STC has been validated by EASA?
- Am I eligible to apply for an STC?
