Description
The MS21151-7 is a genuine Textron Aviation bearing ball rod end — 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 EAR99.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the MS21151-7 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Because the Beechcraft aircraft share extensive structure and hardware, a single part like this is often common across several variants.
A bearing or bushing sets how a shaft or pivot moves and wears; the right part keeps that motion 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.
Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front.
Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections.
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.
