NAICS 336413
Overview
The North American Industry Classification System (NAICS) is the framework U.S. federal statistical agencies use to categorize business establishments for collecting, analyzing, and publishing economic data. Developed under the Office of Management and Budget with partners in Canada and Mexico, NAICS replaced SIC in 1997 and is updated periodically, with the current vintage being 2022. 1
NAICS 336413 covers establishments primarily engaged in manufacturing aircraft parts or auxiliary equipment (excluding engines and aircraft fluid power subassemblies) and/or in developing and making prototypes of such parts and equipment. “Auxiliary equipment” includes crop-dusting apparatus, armament racks, inflight refueling equipment, and external fuel tanks; aircraft power transmission equipment for aviation is also included per NAICS cross-references. 2
What this NAICS covers
- Manufacturing aircraft parts and assemblies other than complete airframes or engines. 2
- Production of auxiliary aircraft equipment such as armament racks, inflight refueling systems, crop-dusting apparatus, and external fuel tanks. 2
- Aircraft power transmission equipment for aviation applications (e.g., gearboxes designed for aircraft). 2
- Development and prototype fabrication of aircraft parts and auxiliary equipment. 2
- Manufacture of aircraft propellers and helicopter rotors. 2
- Fabrication of external aircraft structural accessories and racks not elsewhere classified. 2
