Description
The MS21240-06C022 is a genuine Textron Aviation bearing — a low-friction pivot or rotational support in an assembly. It is fitted to the Beechjet 400/400A. It carries an export classification of ECCN 9A991.
Because the MS21240-06C022 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 Beechcraft 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. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation.
For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk.
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.
