Description
The MS21153-4 is a genuine Textron Aviation rod end — a linkage member carrying motion through a control run. It fits the Beechjet 400/400A. It carries an export classification of ECCN 9A991, weighs 0.06 pounds, and measures 1.7 (L) x 0.7 (W) x 0.55 (H) Inches.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21153-4 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 Beechcraft aircraft, reflecting how much structure and hardware these models have in common.
Parts in a mechanical or control run must match the design geometry to keep rigging, travel, and feel correct. The factory part is built to the manufacturer's material and dimensional specification, so it installs as designed without the surprises a generic equivalent can bring.
OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration. 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.
