Description
The MS21240-07C028 is a genuine Textron Aviation bushing — a sleeve providing a bearing or protective surface at a pass-through or pivot. It is fitted to the Beechjet 400/400A. It carries an export classification of ECCN EAR99.
Because the MS21240-07C028 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.
Because the Beechcraft aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Bearings and bushings are specified for their load, fit, and motion, so the correct part preserves smooth, reliable operation and expected wear life. Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated.
Because aircraft parts are governed by strict airworthiness and traceability rules, fitting the OEM part rather than an unapproved equivalent keeps the installation eligible and the aircraft's records clean. The value of an OEM part is as much in its paperwork and pedigree as its metal — both of which an aircraft's records require.
Beechcraft, founded in Wichita, Kansas in 1932, joined Cessna and Hawker under Textron Aviation in 2014, which today supports the worldwide Beechcraft fleet with genuine factory parts. 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.
