Engineering & Certification Services

Duncan Aviation’s engineering team includes aircraft systems and structures engineers, as well as flight analysts, who have more than 30 years of experience providing approved design changes for interiors and airframe modifications, avionics system installations and system upgrades. These design changes are installed on aircraft that are registered and operated globally.

Every day the engineering team works with the Federal Aviation Administration (FAA) and civil aviation authorities in countries around the world to get validation or approval for the designs developed by the Duncan Aviation team. Many of our designs are developed under our agreements with and with the support of numerous Original Equipment Manufacturers (OEMs).

Additionally, Duncan Aviation holds an Organization Designation Authorization (ODA) from the FAA for Supplemental Type Certificates (STC), Major Repairs and Alterations (MRA) and Parts Manufacturer Approval (PMA). Our team of on-staff and consultant ODA engineers, flight-test and inspection unit members are qualified under the ODA to perform the functions necessary to support timely certifications for the design changes developed by the Duncan Aviation engineering team.

This designation authorizes Duncan Aviation to accomplish these functions on behalf of the FAA. This means the Duncan Aviation ODA may approve major repairs and alterations and issue STCs and PMAs, which potentially saves our customers a great deal of time.
