TURNBUCKLE

The MS21251-2S 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 fitted to the King Air 100, King Air B200, B200T, B200C or B200CT, King Air C90, C90A, C90GT or E90, King Air C90GTi, and King Air C90GTx. It carries an export classification of ECCN EAR99. Because the MS21251-2S 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. Across the 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. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation. Beechcraft was founded in Wichita, Kansas in 1932 by Walter and Olive Ann Beech, and has been part of Textron Aviation since 2014, uniting with Cessna and Hawker. The King Air first flew in 1964 and became the best-selling business turboprop in history — still built today as the King Air 260 and 360.
