Other Aircraft Parts and Auxiliary Equipment Manufacturing
NAICS 336413 · United States · 2022 edition
This U.S. industry comprises establishments primarily engaged in (1) manufacturing aircraft parts or auxiliary equipment (except engines and aircraft fluid power subassemblies) and/or (2) developing and making prototypes of aircraft parts and auxiliary equipment. Auxiliary equipment includes such items as crop dusting apparatus, armament racks, inflight refueling equipment, and external fuel tanks.
Start the review with aviation products liability.
For Other Aircraft Parts and Auxiliary Equipment Manufacturing, the saved research highlights aviation products liability, workers' compensation, commercial property. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- What specific types of parts or components are manufactured, and for what aircraft categories — commercial air transport, general aviation, military, or rotorcraft?
- Does the operation hold FAA PMA, TSOA, or other quality certifications, and is it operating under AS9100 or a comparable quality management system?
- What is the split between prototype/R&D work and established production runs?
- Who are the primary customers — OEMs, defense prime contractors, MRO providers, or distributors — and what contractual insurance requirements apply?
- What is the prior aviation products liability claims history, including any incidents under investigation?
- For Other Aircraft Parts and Auxiliary Equipment Manufacturing, what should the underwriter know about prior aviation products liability claims, even if resolved?
- For Other Aircraft Parts and Auxiliary Equipment Manufacturing, what should the underwriter know about prototype or r&d-only operations without established production quality systems or certifications such as as9100?
- For Other Aircraft Parts and Auxiliary Equipment Manufacturing, what should the underwriter know about parts supplied for commercial air transport (part 25 aircraft) versus general aviation?

Establishments in this class manufacture components and auxiliary equipment for aircraft — examples include structural parts, fairings, fuel system components, armament racks, crop dusting apparatus, inflight refueling equipment, and external fuel tanks. Operations typically involve precision machining, composite fabrication, or assembly under strict quality management systems, often supplying OEMs, defense contractors, or MRO providers. Prototype development may occur alongside production.
