Certification Services

EASA Part 21J Design Organization

Through the EASA Part 21J approved design organization, Scandinavian Avionics Design ApS (SAD) - member of The SA Group, offers development of supplemental type certificates (STC) and minor changes to existing aircraft type certificates, covering any avionics or electrical modification of any aircraft or helicopter application.

Over the years, SAD has developed more than 700 STCs and certification packages for a wide range of avionics system modifications in a wide range of aircraft types.

SAD also provides certification packages complying with a wide range of other military and civil regulations and requirements, customized to the specific rules and regulations in any specific area.

STC Development

Supplemental Type Certificates are developed for any type of avionics system upgrade as part of a complete turn-key solution. This including parts supply, installation and training or as a single project for other qualified modification centers with relevant installation capability and approvals.

In addition to avionics systems upgrades, SAD offers certification of structural upgrades and interior modifications, performed by SA and/or selected partners.

New certification packages are being developed every month and SAD supports any type of avionics upgrade or interior modifications for any type of aircraft as specified and agreed with the customers.
