Authorized and Trusted to Provide a Full Range of STC Services

If you need equipment installed on an aircraft that requires a Supplemental Type Certificate (STC), then an Organization Designation Authorization (ODA) program can save you time and expedite your product to market. As a Federal Aviation Administration (FAA) designated ODA, 3S Engineering and 3S Certification is your partner to ensure the most efficient and quickest path to FAA certification.

  • FAA Designated ODA
  • Provider of 14 CFR Part 23, 25, 27 & 29 STCs
We recognize that the aviation environment has reached a level of complexity where we can’t achieve further safety improvements by following a purely rule-based approach. Michael Huerta, Federal Aviation Administrator

3S Provides the Fastest Path to Certification

The FAA has changed its focus from direct approval of data to an oversight role of delegated organizations, thus creating the need to delegate additional authority to those delegated organizations that are committed to quality and demonstrate compliance. 3S is one of the FAA’s preferred ODAs.

With our experience and resources, 3S offers a “turnkey” solution that ensures the fastest path to completion and certification. This means less aircraft down-time and your project speed to market will be improved by at least six to 10 months.
