UNION

The MS21902J10 is a genuine Textron Aviation union supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It fits the Citation III, VI or VII, Citation Latitude, Citation Sovereign or Sovereign+, Citation X, and Citation X+. It carries an export classification of ECCN 9A991, weighs 0.17 pounds, and measures 1.55 (L) x 1.2 (W) x 1.1 (H) Inches. Because the MS21902J10 is an original-equipment (OEM) part sourced directly from Textron Aviation, it matches the exact specification and placement called out in the aircraft's type design and maintenance data — assurance a generic substitute cannot offer. Because the Cessna Citation aircraft share extensive structure and hardware, a single part like this is often common across several variants. Supplied as a defined part in the manufacturer's catalog, its exact role is set by the aircraft's parts and maintenance data. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front. Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance. The Cessna name is among the most recognized in aviation — founded in Wichita, Kansas in 1927 and part of Textron since 1992, today a cornerstone of Textron Aviation. The Citation family is the best-selling line of business jets ever built, and more than 7,500 have been delivered worldwide.
