CLAMP

The MS21920-30 is a genuine Textron Aviation clamp — a fastening or retaining hardware item used in the airframe. It is fitted to the Citation Excel, XLS, XLS+, XLS Gen 2, 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 0.11 lbs, and measures 4 (L) x 3.55 (W) x 0.75 (H) in. Supplied directly by Textron Aviation as an original-equipment (OEM) part, the MS21920-30 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records. Parts like this are shared across the Cessna Citation aircraft, reflecting how much structure and hardware these models have in common. Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. 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. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk. 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.
