NUT

The MS21340-24 is a genuine Textron Aviation nut — a fastening or retaining hardware item used in the airframe. It is applicable to the Citation Excel, XLS, XLS+, XLS Gen 2, Citation III, VI or VII, Citation Latitude, Citation Longitude, Citation Sovereign or Sovereign+, Citation X, and Citation X+. It carries an export classification of ECCN EAR99. Because the MS21340-24 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. Across the Cessna Citation fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. Aircraft hardware is called out to a specific specification for each location; an off-the-shelf equivalent is rarely acceptable. Using the factory part number preserves configuration control, so the airframe stays consistent with its approved type design and the work is straightforward to sign off at inspection. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value. 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. 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.
