Analysis
NAICS 336413 is the 2022 national industry for other aircraft parts and auxiliary equipment manufacturing, part of 33641 (Aerospace Product and Parts Manufacturing). Census lists 13 example activities under it in the official index.
County Business Patterns counts 966 US establishments in this code in 2023, employing 104,573 people at an average annual payroll of $85,665 per employee (74th percentile of national industries). 21% of the establishments have fewer than five employees, which points to larger operations.
By establishments it ranks 1st of the 6 codes at this level within Aerospace Product and Parts Manufacturing, with 50.7% of them.
Census lists 7 related activities that belong elsewhere, most often in 336412, 334511, 336320 and 336419. Businesses that do several things are classified by their primary activity, the one that generates the most value, so check those boundaries before settling on this code.
Its index entries, the activities Census uses to assign businesses to this code, include aircraft assemblies, subassemblies, and parts (except…, aircraft auxiliary parts (e.g., crop dusting, external fuel…, aircraft brakes manufacturing and aircraft control surface assemblies manufacturing, among 13 in all.
Between 2018 and 2023 the number of establishments grew 8% and employment rose 2%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
Official definition
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.
