SCREW

The MS21318-15 is a genuine Textron Aviation screw — a fastening or retaining hardware item used in the airframe. It is fitted to the 1900 Airliner, 1900C Airliner, 1900D Airliner, Baron Series B55, E55, 58 or G58, Bonanza 36, King Air B200, B200T, B200C or B200CT, King Air B200GT, King Air B200GT Fusion or B200CGT Fusion, King Air C90GTi, and King Air C90GTx, among other compatible variants. It carries an export classification of ECCN EAR99. Because the MS21318-15 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, Baron, Bonanza, and King Air aircraft, reflecting how much structure and hardware these models have in common. Aircraft hardware is called out to a specific specification for each location; an off-the-shelf equivalent is rarely acceptable. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk. Built by Beechcraft — the Wichita, Kansas manufacturer founded in 1932 and part of Textron Aviation since 2014 — this part carries a name long associated with rugged, capable aircraft. 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.
