TURNBUCKLE

The MS21254-3LS 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, Citation III, VI or VII, Citation V, Ultra, Encore or Encore+, King Air 100, King Air 350 Fusion, King Air 350C FM-36 & On, King Air 350C Fusion, and King Air 350i, among other compatible variants. It carries an export classification of ECCN EAR99. Because the MS21254-3LS 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. Parts like this are shared across the Beechcraft 1900, Cessna Citation, and Beechcraft King Air aircraft, reflecting how much structure and hardware these models have in common. 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.
