FAA & EASA Engineering Certifications

As an FAA-designated Organization Designation Authorization (ODA), SNC’s subsidiary 3S Engineering and 3S Certification (3S) is your partner for the most efficient FAA certification process. With SNC and 3S, customers can accelerate time-to-market by receiving Supplemental Type Certificates (STC) for aircraft equipment installations from an ODA.

SNC and 3S provide superior services with certification schedules that lower FAA involvement in STC projects. 3S has the experts to perform and support all phases of aviation projects.

Our ODA processes ensure schedule compression, controls and efficiencies over typical FAA Aircraft Certification Office (ACO)-managed projects. As an ODA, we can issue STCs directly under the delegated authority of the FAA.

This FAA designation allows 3S to act on behalf of the FAA to approve and issue STCs covering modifications to a wide variety of fixed-wing and rotary aircraft. It is a full-service company offering tailored solutions for aircraft modification, design and FAA and European Aviation Safety Agency (EASA) certification services.
