Description
The MS21915J5-4 is a genuine Textron Aviation bushing that protects and locates a shaft, pin, cable, or cord where it passes through structure. It is applicable to the Citation III, VI or VII and Citation X. It carries an export classification of ECCN EAR99.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the MS21915J5-4 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Across the Cessna Citation fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
Bearings and bushings are specified for their load, fit, and motion, so the correct part preserves smooth, reliable operation and expected wear life. For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for.
Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide.
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 Citation family is the best-selling line of business jets ever built, and more than 7,500 have been delivered worldwide.
