Design, Engineering & STC Services

Design, Engineering and Certification

The SA Group designs and develops complex structural and electrical complete turn-key avionic modifications for basically any application and is involved in complete aircraft nose to tail engineering programs. Providing all interfaces and interconnections for complete aircraft development programs, e.g.: 5-tube EFIS upgrade including engine interface for Part-25 aircraft, special mission upgrades with special designed interface concepts, camera mountings, SLAR & FLIR installations, and interface solutions,PRNAV and LPV upgrades, IFE concepts to name a few examples. 

The Design, Engineering and Certification department develops complete STC's and minor changes, which includes various essential documents for certification of avionics modifications, including, but not limited to:

  • Technical orders
  • Certification programs
  • Cockpit layouts
  • Wiring diagrams
  • Structural drawings
  • Structural strength calculations
  • Compliance records
  • Load analysis
  • Weight and balance calculations
  • Ground and flight test procedures
  • Continuous airworthiness
  • Flight manual supplements
  • EMI assessments

All the above and other relevant documentation can be performed by The SA Group to certify and complete any modification of smaller as well as larger aircrafts and helicopters. 

The SA Group has a skilled team of engineers available, spread all over The SA Group locations around the world. Our engineers have an extensive experience of up to more than 40 years within the avionics business, and The SA Group continues to train and keep the staff up to date with all current requirements and knowledge on the latest equipment, avionics and concepts within the area of avionics and airborne electronics.

Basically, The SA Group engineering team is ready to take on any challenge, within the field of avionics and aircraft electronics.

EASA Part 21J Design Organization

Through the EASA Part 21J approved design organization, Scandinavian Avionics Design, 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, The SA Group has developed more than 700 STCs and certification packages for a wide range of avionics system modifications in a wide range of aircraft types.

The SA Group 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.

The SA Group has the privilege of approving minor modifications, flight conditions and AFM Supplements in-house, and our high experience and cooperation with EASA is continually growing our capabilities and possibilities. 

STC Development

Supplemental Type Certificates are developed for any type of avionics system upgrade as part of a complete turn-key solution, 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, The SA Group offers certification of structural upgrades and interior modifications, performed by SA and/or selected partners.

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