Which code does this activity belong in?
NAICS 336412 covers establishments manufacturing aircraft engines and engine parts, including prototype development and major overhauls of aircraft propulsion systems. The key distinction from NAICS 336411 is that this code focuses exclusively on engines and propulsion system components rather than complete aircraft assembly and modification. Establishments performing non-engine aircraft parts and auxiliary equipment manufacturing are classified in NAICS 336413, while those making propulsion units for guided missiles and space vehicles belong in NAICS 336415.
