CLAMP

The MS21920-35 is a genuine Textron Aviation clamp used to fasten, secure, or retain components during assembly of the airframe. It fits the Citation CJ2 or CJ2+, Citation CJ3, CJ3+, CJ3+ Gen 2, CJ3 Gen 3, and Citation Excel, XLS, XLS+, XLS Gen 2. It carries an export classification of ECCN 9A991, weighs 0.12 pounds, and measures 4.55 (L) x 4.3 (W) x 0.65 (H) Inches. Because the MS21920-35 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. Aircraft hardware is called out to a specific specification for each location; an off-the-shelf equivalent is rarely acceptable. Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front. 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.
