What is DERLink?

DERLink is the FAA-aligned approval network that powers AvioDesign.
It connects vetted DERs, engineers, and specialists across all certification disciplines to ensure your project has the right expertise at the right time.

Through DERLink we:

  • Match projects with vetted DERs and engineers.

  • Confirm availability, labor rates, and turnaround times before work begins.

  • Coordinate communication and technical deliverables behind the scenes.

  • Keep your certification package fully staffed, supported, and moving forward.

AvioDesign manages your project and delivers the FAA-ready package. DERLink ensures the technical depth and approvals are always in place.
