Description
The MS21288-03 is a genuine Textron Aviation bolt — a fastening or retaining hardware item used in the airframe. It is applicable to the Citation III, VI or VII. It carries an export classification of ECCN EAR99, weighs 0.01 pounds, and measures 0.3 (L) x 0.3 (W) x 0.65 (H) Inches.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21288-03 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.
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. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk.
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.
