FASTENER

The MS21332-4 is a genuine Textron Aviation fastener 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 MS21332-4 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. Parts like this are shared across the Cessna Citation aircraft, reflecting how much structure and hardware these models have in common. Strength grade and finish define aircraft hardware, so matching the specified part keeps the joint as designed. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide. Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections. 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. Cessna traces to the company Clyde Cessna founded in Wichita, Kansas in 1927; Textron Inc. acquired it in 1992, and since 2014 it has anchored Textron Aviation alongside Beechcraft and Hawker. The Citation family is the best-selling line of business jets ever built, and more than 7,500 have been delivered worldwide.
