Advanced Solutions to Complex Challenges

In-house engineering, design, drafting and analysis for all aspects of aircraft modifications and upgrades fueled by the legacy of Nextant Aerospace. From the development of STCs to part certification and the integration of cutting-edge in-flight connectivity, we provide streamlined, comprehensive solutions to complex technical challenges.

Engineering & Certification


Our engineering team covers everything from major repairs to manufacturing of PMA parts. Design engineering including 3D modeling, FAA approved repairs, Supplemental Type Certificate (STC), 
DER and DAR services, Parts Manufacturing Approval (PMA) certification.

STC & PMA

Experts you can count on for Parts Manufacturer Approval and Supplemental Type Certificates. Navigating the requirements for an STC or PMA can be daunting. On site technical staff, including Designated Engineering Representatives (DER) and Designated Airworthiness Representatives (DAR) complete the design, testing, engineering, prototype and production needed – more than 28 completed to date. Whether there’s a need to quickly integrate new technologies to existing aircraft or remanufacture difficult-to-source parts, our in-house expertise is unmatched in the industry.
