FAQ n.21901

Why can't I find an STC on the EASA STC List?


The Agency applies its best efforts to ensure completeness of this list.

The EASA STC list compiles Supplemental Type Certificates issued by EASA since 03/06/2004. 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
  • Recently issued STCs may not yet appear on the list

Should you discover missing data or for any other question, we kindly request you to contact the following mailbox STC [at] easa.europa.eu

Please also refer to our FAQ on “Who do I contact to request a copy of a grandfathered STC?””
