This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If adapted for helicopter rotor drive
Helicopter engines classify under other spark-ignition engines, not specifically aircraft fixed-wing.
If imported as unfinished engine core for assembly
Incomplete engines without final calibration fall under outboard motor provisions.
If marketed for experimental homebuilt aircraft kits
Engines not FAA-certified for type-certificated aircraft may classify as general linear acting engines.
