ADAPTER

The MS21900J8 is a genuine Textron Aviation adapter supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It fits the Citation Excel, XLS, XLS+, XLS Gen 2 and SkyCourier. It carries an export classification of ECCN 9A991. As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21900J8 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 SkyCourier fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. As a factory-supplied item for a type-certificated aircraft, this part is defined by the manufacturer's specification and applicability data. The factory part is built to the manufacturer's material and dimensional specification, so it installs as designed without the surprises a generic equivalent can bring. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger. 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. 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.
