DER Authorization


FAA DESIGNATED ENGINEERING REPRESENTATIVE (DER)

Authority to certify structural modifications and alterations to aircraft

Michael J. Pagnotta has been an FAA Structures DER (Part 23, 25, and 27) since 1996. New, modified, or repaired aircraft must comply with the applicable Federal Aviation Regulations (FARs). Compliance can be approved by a DER without direct FAA interaction. The DER serves as the “eyes and ears” of the FAA and approves the new, modified, or repaired aircraft or rotorcraft based on the findings of compliance.

DER SERVICES PERFORMED:

•  Structural analysis of aircraft and rotorcraft in accordance with the applicable FAR
• Finding compliance with the FAR for new, modified, or repaired aircraft or rotorcraft
• Test witnessing and approval in support of compliance finding
• Issue of 8110-3 forms approving the new, modified, or repaired aircraft or rotorcraft
