Description
The MS21251B8L is a genuine Textron Aviation turnbuckle supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It is fitted to the Beechjet 400/400A. It carries an export classification of ECCN EAR99.
Because the MS21251B8L 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.
This is a cataloged factory part whose form, fit, and function are established by the manufacturer's approved data. Using the factory part number preserves configuration control, so the airframe stays consistent with its approved type design and the work is straightforward to sign off at inspection.
Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated. Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application.
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.
