Based on the EASA Part-21G DOA approval, SA has developed more than 400 STC’s (Supplemental Type Certificates), which enables us to install a wide variety of systems in a wide range of aircraft types instantly.

In addition to general avionics systems upgrades, SA is approved for certifying interior modifications performed by our selected partners.

We are constantly developing additional certification packages and should be pleased to support any aircraft avionics or interior upgrade you may require. SA provides STC’s as part of a complete turnkey aircraft modification or parts of it as required by the specific program.

We also offer documentation & STC’s separately for installation by another qualified organization with relevant capability and approval.
