STUD

The MS21325-5 is a genuine Textron Aviation stud used to fasten, secure, or retain components during assembly of the airframe. It is fitted to the Citation III, VI or VII, Citation Latitude, and Citation Sovereign or Sovereign+. It carries an export classification of ECCN EAR99. Because the MS21325-5 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. Strength grade and finish define aircraft hardware, so matching the specified part keeps the joint as designed. Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections. Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated. Because aircraft parts are governed by strict airworthiness and traceability rules, fitting the OEM part rather than an unapproved equivalent keeps the installation eligible and the aircraft's records clean. 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.
