TURNBUCKLE

The MS21251B2S 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 applicable to the 1900 Airliner, 1900C Airliner, 1900D Airliner, Baron Series B55, E55, 58 or G58, Bonanza 36, Bonanza F33, G33, F33A or F33C, Citation CJ2 or CJ2+, Citation Excel, XLS, XLS+, XLS Gen 2, Citation Sovereign or Sovereign+, and Citation X, among other compatible variants. It carries an export classification of ECCN EAR99. As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21251B2S 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. Across the Beechcraft 1900, Beechcraft Baron, Beechcraft Bonanza, Cessna Citation, and Beechcraft King Air fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. As a factory-supplied item for a type-certificated aircraft, this part is defined by the manufacturer's specification and applicability data. Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance. These aircraft are built by Textron Aviation, which unites Cessna (founded 1927) and Beechcraft (founded 1932) under one Wichita, Kansas company since 2014. Derived from the King Air, the 19-passenger Beechcraft 1900 airliner (built 1982–2002) remains in service with regional and cargo operators.
