Description
The S1166-1 is a genuine Textron Aviation seal used to keep a joint or pass-through tight. It fits the Caravan or Grand Caravan EX and Skyhawk. It carries an export classification of ECCN EAR99.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the S1166-1 is built to the aircraft maker's specification and cross-references the type design as documented in the maintenance data. Choosing the genuine part over an unapproved substitute preserves configuration control and simplifies inspection sign-offs.
Across the Cessna Caravan and Skyhawk fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
Sealing components are sized and compounded for the fluids, temperatures, and pressures they contain, so the exact specified part maintains a tight joint. 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.
For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for.
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 Caravan is a single-engine PT6-powered utility turboprop in continuous production since 1984, valued for its rugged versatility in passenger, cargo, and float operations.
