Description
The S2554-4 is a genuine Textron Aviation hose of a type generally used to route fluid, air, or wiring through the airframe. It is fitted to the Caravan or Grand Caravan EX, Citation CJ4, CJ4 Gen 2, CJ4 Gen 3, Skyhawk, Skylane, and Stationair. It carries an export classification of ECCN EAR99.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the S2554-4 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, Citation, Skyhawk, Skylane, and Stationair fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
Because it handles pressurized fluid or air, a component like this is specified precisely for its service — the right part keeps the system sound. Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance.
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. Cessna's single-engine Caravan turboprop, in production since 1984, is one of the most widely used utility aircraft in the world.
