Last updated: August 2026 dataReplacement and overhaul parts for spark-ignition piston and rotary engines used in aircraft—including cylinders, crankshafts, magnetos, carburetors, and fuel-injection components not captured by more specific headings—are classified here. Airworthiness traceability is a defining commercial requirement: parts must typically carry FAA-PMA (Parts Manufacturer Approval) or equivalent bilateral-agreement certification to be legally installed on certificated aircraft, which distinguishes this trade from general automotive engine parts. Importers and MRO operators should maintain complete traceability documentation from the foreign manufacturer through to the US port of entry.

FAA-PMA parts are manufactured under an FAA-issued Parts Manufacturer Approval and are legally installable on certificated aircraft. Surplus, used, or non-PMA parts may clear CBP under the same tariff classification but cannot be legally installed on US-certificated aircraft without additional FAA authorization. Importers should ensure that airworthiness documentation accompanies the shipment and is retained for maintenance records.
If a magneto or carburetor is identifiable by design and specification as suitable for use solely or principally in aircraft spark-ignition engines, it should be classified as an aircraft engine part under this heading rather than as a general ignition or fuel-system component. The principal-use determination relies on the part's technical specifications, OEM part number, and any airworthiness approval documentation.
