BARREL

The MS21251B3S is a genuine Textron Aviation barrel supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It fits the 1900 Airliner, 1900C Airliner, 1900D Airliner, Baron Series B55, E55, 58 or G58, Beechjet 400/400A, Bonanza 36, Bonanza F33, G33, F33A or F33C, Citation CJ2 or CJ2+, Citation CJ4, CJ4 Gen 2, CJ4 Gen 3, and Citation Sovereign or Sovereign+, among other compatible variants. It carries an export classification of ECCN EAR99. Because the MS21251B3S 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 1900, Beechcraft Baron, Beechcraft, Beechcraft Bonanza, Cessna Citation, Beechcraft King Air, and Beechcraft Premier aircraft share extensive structure and hardware, a single part like this is often common across several variants. Supplied as a defined part in the manufacturer's catalog, its exact role is set by the aircraft's parts and maintenance data. Both the Cessna and Beechcraft lines are supported today by Textron Aviation, formed in 2014 to unite the two historic Wichita manufacturers with Hawker. The Beechcraft 1900, a 19-passenger regional airliner derived from the King Air, was produced from 1982 to 2002 and still serves commuter and cargo operators worldwide.
