Description
The MS21288-09 is a genuine Textron Aviation bolt — a fastening or retaining hardware item used in the airframe. It is fitted to the Citation Mustang. It carries an export classification of ECCN EAR99.
Because the MS21288-09 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.
Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front.
The Cessna name is among the most recognized in aviation — founded in Wichita, Kansas in 1927 and part of Textron since 1992, today a cornerstone of Textron Aviation. 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.
