UNION

The MS21902J8 is a genuine Textron Aviation union supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It is applicable to the Citation Excel, XLS, XLS+, XLS Gen 2, Citation III, VI or VII, Citation Latitude, Citation Longitude, Citation Sovereign or Sovereign+, Citation X, Citation X+, Premier Model 390, and SkyCourier. It carries an export classification of ECCN 9A991. Because the MS21902J8 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, Beechcraft Premier, and Cessna SkyCourier 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. Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated. Both the Cessna and Beechcraft lines are supported today by Textron Aviation, formed in 2014 to unite the two historic Wichita manufacturers with Hawker. Cessna's Citation line, launched with the Model 500 in the early 1970s, grew into the best-selling business-jet family in the world, spanning today from the light M2 to the super-midsize Longitude.
