Description
The MS21250-05026 is a genuine Textron Aviation bolt — a fastening or retaining hardware item used in the airframe. It is applicable to the Beechjet 400/400A. It carries an export classification of ECCN EAR99.
Because the MS21250-05026 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.
Across the Beechcraft fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
Aircraft hardware is called out to a specific specification for each location; an off-the-shelf equivalent is rarely acceptable. 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 substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application. 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.
Beechcraft was founded in Wichita, Kansas in 1932 by Walter and Olive Ann Beech, and has been part of Textron Aviation since 2014, uniting with Cessna and Hawker. 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.
