Description
The MS21919WDF45 is a genuine Textron Aviation clamp — a fastening or retaining hardware item used in the airframe. It is fitted to the Citation Sovereign or Sovereign+. It carries an export classification of ECCN EAR99, weighs 0.07 pounds, and measures 5.2 (L) x 4.15 (W) x 0.75 (H) Inches.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21919WDF45 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 fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
The value of an OEM part is as much in its paperwork and pedigree as its metal — both of which an aircraft's records require.
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. 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.
