Description
The MS21915-5-4 is a genuine Textron Aviation bushing that protects and locates a shaft, pin, cable, or cord where it passes through structure. It carries an export classification of ECCN EAR99.
Bearings and bushings are specified for their load, fit, and motion, so the correct part preserves smooth, reliable operation and expected wear life. Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections.
Cross-check the part number against your maintenance and parts documentation to confirm fit and current effectivity for your airframe. 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Because a single part number can be superseded or vary by effectivity, confirm applicability against your aircraft's Illustrated Parts Catalog (IPC) and serial-number effectivity before ordering. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front.
Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide.
Textron Aviation traces its roots to Cessna, founded in Wichita, Kansas in 1927, and Beechcraft, founded there in 1932 — two of general aviation's most storied names, united under one company since 2014.
