Engineering & Certification Services

Good ideas are the impetus of innovation, especially in aviation. However, if they’re not properly evaluated, developed, planned, integrated, tested, and certified by subject-matter experts, they may remain just good ideas. As the saying goes, time has a way of killing deals and ideas.

Duncan Aviation can help make your idea a reality. Our Engineering & Certification Services Team includes aircraft systems, interiors, and structures engineers and for the past 30 years, we’ve provided design data and all of the supporting documentation required to certify many types of alterations.

Through close collaboration with Duncan Aviation’s ODA (Organization Designation Authorization), the Engineering & Certification Services team provides guidance and documentation for all manner of aircraft modifications including interior alterations, avionics installations and upgrades, and government and special missions projects by producing hundreds of Supplemental Type Certificates (STCs), MRAs (Major Repairs, Major Alterations and Airworthiness), and PMAs (Parts Manufacturer Approvals). See our STC Library for information about some of our types of projects.

We have provided engineering, certification, and consulting services to aviation OEMs (Original Equipment Manufacturers), major vendors and service providers, private aircraft owners and operators, and commercial aerospace companies. Some clients have used our services from the inception of an idea through the certification process while others have sought our services for narrower portions of their projects.

Working with the FAA and civil aviation authorities worldwide, we secure approval or validation for the designs developed by our Duncan Aviation team. Additionally, Duncan Aviation holds an ODA (Organization Designation Authorization) from the FAA for STCs, MRAs, and PMAs.

Our team of ODA engineering, flight-test, and inspection unit members are qualified under the ODA to perform the functions necessary to support timely approval of data for the design changes the engineering team develops. Under the ODA, Duncan Aviation performs these functions on behalf of the FAA, which saves our customers a great deal of time.

If you need assistance in getting your idea off the ground, give us a call. Let’s explore what we can do together.
