FUEL SENDING UNIT

The S3331-1 is a genuine Textron Aviation fuel sending unit supplied as a built-up assembly of several components in a single installable unit. It fits the Skyhawk. It carries an export classification of ECCN EAR99. Supplied directly by Textron Aviation as an original-equipment (OEM) part, the S3331-1 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records. Because the Cessna Skyhawk aircraft share extensive structure and hardware, a single part like this is often common across several variants. This is a cataloged factory part whose form, fit, and function are established by the manufacturer's approved data. The value of an OEM part is as much in its paperwork and pedigree as its metal — both of which an aircraft's records require. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide. Using the factory part number preserves configuration control, so the airframe stays consistent with its approved type design and the work is straightforward to sign off at inspection. Built by Textron Aviation, whose Cessna line was founded in Wichita, Kansas in 1927 and joined Textron in 1992, this part carries one of general aviation's most storied names. The Cessna 172 Skyhawk is the most-produced aircraft in history, with more than 44,000 built since 1956, and remains in production under Textron Aviation.
