CLAMP

The MS21920-37 is a genuine Textron Aviation clamp used to fasten, secure, or retain components during assembly of the airframe. It is fitted to the Citation Excel, XLS, XLS+, XLS Gen 2, Citation V, Ultra, Encore or Encore+, and SkyCourier. It carries an export classification of ECCN EAR99. As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21920-37 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. Because the Cessna Citation and SkyCourier aircraft share extensive structure and hardware, a single part like this is often common across several variants. Aircraft hardware is called out to a specific specification for each location; an off-the-shelf equivalent is rarely acceptable. 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. Built by Textron Aviation, whose Cessna line was founded in Wichita, Kansas in 1927 and joined Textron in 1992, this part carries one of general aviation's most storied names. The Citation family is the best-selling line of business jets ever built, and more than 7,500 have been delivered worldwide.
