Description
The MS21240-06C012 is a genuine Textron Aviation bushing that protects and locates a shaft, pin, cable, or cord where it passes through structure. It fits the Beechjet 400/400A.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21240-06C012 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.
Across the Beechcraft fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
A bearing or bushing sets how a shaft or pivot moves and wears; the right part keeps that motion as designed. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide.
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. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front.
Built by Beechcraft — the Wichita, Kansas manufacturer founded in 1932 and part of Textron Aviation since 2014 — this part carries a name long associated with rugged, capable aircraft. The Beechjet 400, which began life as the Mitsubishi Diamond and later became the Hawker 400, is a light business jet supported today through Textron Aviation.
