Description
The MS21919WDG45 is a genuine Textron Aviation clamp used to fasten, secure, or retain components during assembly of the airframe. It is fitted to the Citation V, Ultra, Encore or Encore+. It carries an export classification of ECCN EAR99.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21919WDG45 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.
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. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide.
Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
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.
