UNION

The MS24392J4 is a genuine Textron Aviation union supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It is fitted to the 1900 Airliner, 1900C Airliner, 1900D Airliner, Citation III, VI or VII, King Air B200, B200T, B200C or B200CT, King Air C90GTi, and King Air C90GTx. It carries an export classification of ECCN 9A991. Because the MS24392J4 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. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation. 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.
