The Structure Behind Modern Certification
AvioDesign provides the framework that keeps certification programs moving in a changing FAA landscape.
Through DERLink™ and EPEC™, we connect organizations to the right technical expertise, maintain regulatory alignment, and deliver fully client-owned, approval-ready documentation.
As FAA Order 8100.15C drives more structured oversight within ODAs, AvioDesign serves as the independent backbone that helps DERs, ODAs, engineering firms, and STC holders operate efficiently within a unified and auditable support structure.
DERLink™ – FAA-Aligned Approval Network
The technical engine behind certification success.
DERLink connects each project with vetted FAA Designated Engineering Representatives and supporting engineers across all major disciplines. This is how AvioDesign delivers consistent, approval-ready substantiation for modifications, system integrations, and design changes.
DERLink support includes:
• Multi-discipline DER access (avionics, structures, EWIS, flammability, software, etc)
• Organized documentation and complete traceability for FAA or ODA acceptance
• A unified compliance approach across disciplines
• Cross-discipline collaboration for efficient project completion
DERLink keeps technical approvals structured, coordinated, and ready for audit.
EPEC™ – Extended Program for Engineering Compliance
The post-certification framework that protects your STC.
EPEC manages the continued airworthiness and lifecycle of each STC or modification program by keeping documentation organized, installations supported, and approvals sustainable over time. Offered under AvioDesign or client branding, EPEC provides a scalable way to maintain control of certification long after approval.
EPEC support is tailored to each organization’s needs and can include the following services:
• Licensing and installation support for STCs
• Field and operator support under AvioDesign or client branding
• Documentation and applicability updates
• Activity and field intelligence reporting
• Data continuity management for long-term traceability
• Warranty alignment with component manufacturers
When revisions or amendments are required, EPEC compiles and prepares the necessary data and coordinates completion through AvioDesign or DERLink for review and pricing options.
EPEC programs scale with your organization whether supporting a single modification or managing an entire portfolio.
Project Integration Support
AvioDesign supports certification programs for MROs, operators, engineering firms, and STC holders by integrating DERLink and EPEC into a unified, approval-ready structure. We ensure that engineering data, discipline involvement, and required substantiation flow smoothly into the FAA or ODA acceptance path.
Integration support includes:
Aligning DERLink discipline coverage with project requirements
Organizing substantiation and compliance data into a unified format
Preparing approval-ready documentation for FAA or ODA review
Supporting partner firms who manage primary project coordination
AvioDesign serves as the structured backbone that enables partner coordinators, engineering teams, and DERs to operate efficiently throughout the certification cycle.
