336411: Aircraft Manufacturing

What this code covers

NAICS 336411 covers building or assembling complete aircraft, manned or unmanned, building aircraft prototypes, converting aircraft through major changes to their systems, and complete overhaul and rebuilding that restores an aircraft to its original design specification. Parts and assemblies belong under 336413, and engines under 336412.

Few small shops carry this as a primary code, but plenty of work is solicited under it: modification kits, depot-level structural repair, small unmanned aircraft, tooling and ground support for a production line, and sustaining engineering. Buyers include Naval Air Systems Command, the Air Force Life Cycle Management Center, Army Contracting Command at Redstone Arsenal, Special Operations Command, the Coast Guard and, for unmanned aircraft, several civil agencies.

What federal buyers typically ask for

AS9100 is close to universal, with Nadcap accreditation for any special process you perform in house. Platforms derived from civil aircraft add FAA production and repair station rules. Configuration management, technical data rights and a government quality representative on site are normal on production contracts, and first article inspection applies to every new part number.

The DFARS specialty metals clause applies to almost every structural item because titanium, steel and nickel alloys run through the airframe. Aircraft and their major components are ITAR controlled under the aircraft category, so registration and export-controlled data handling are prerequisites. Contracts with controlled unclassified information carry CMMC. The counterfeit electronic part clause reaches any avionics or wiring you supply.

Complete aircraft and major modifications are typically unrestricted or sole source to the original manufacturer. Small business set-asides appear for small unmanned aircraft, modification kits, overhaul of light aircraft and training aircraft, and support equipment. Most small shop revenue under this code arrives as subcontracts from the airframe primes.
