Description
The MS21915-6-5 is a genuine Textron Aviation bushing carbon steel — a sleeve providing a bearing or protective surface at a pass-through or pivot. It is fitted to the Citation III, VI or VII. It carries an export classification of ECCN 9A991.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21915-6-5 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.
Parts like this are shared across the Cessna Citation aircraft, reflecting how much structure and hardware these models have in common.
Fit and load rating define a bearing's job, so matching the specified part protects both function and service life. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk.
Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application.
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.
