ELBOW

The MS21908J4 is a genuine Textron Aviation elbow supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It is applicable to the Citation III, VI or VII, Citation Latitude, Citation Sovereign or Sovereign+, Citation X, and Premier Model 390. It carries an export classification of ECCN 9A991. As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21908J4 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 Citation and Beechcraft Premier fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. This is a cataloged factory part whose form, fit, and function are established by the manufacturer's approved data. For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide. These aircraft are built by Textron Aviation, which unites Cessna (founded 1927) and Beechcraft (founded 1932) under one Wichita, Kansas company since 2014. The Citation family is the best-selling line of business jets ever built, and more than 7,500 have been delivered worldwide.
