Certification Support Services

At AvioDesign, we coordinate services that keep certification and modification projects on track. Our experience in program support and regulatory coordination allows us to deliver practical, submission-ready results with complete client ownership.

A few of our services include:

Project Support

AvioDesign assists MROs and operators with certification projects ranging from avionics modifications to structural changes. We coordinate the right expertise to take your project from initial planning through final approval, including wiring diagrams, EWIS, structural analysis, and DER approvals. Our role is to keep everything organized, aligned with FAA expectations, and moving forward without unnecessary delays.

DER Approvals

We connect your project with FAA Designated Engineering Representatives (DERs) across all disciplines. By coordinating directly with the right DER expertise, we ensure your projects receive accurate, FAA-aligned approvals with complete documentation ready for submission or integration into your records.

Partnerships

We support engineering firms, OEMs, and ODAs that require additional DER coverage or overflow support. We act as an extension of your team, handling DER coordination and delivering a structured package for your review and use. Whether it is filling a short-term DER gap or managing larger certification efforts, our network adapts to your needs.

STC Revisions & Amendments

AvioDesign helps extend the life and value of existing STCs. Whether you need AML expansions, parts substitutions, or other amendments, we coordinate the DER approvals to keep your certification current. This includes adding or revising Flight Manual Supplements, Instructions for Continued Airworthiness, and related documentation tied to AML changes.
