SCREW

The MS21318-13 is a genuine Textron Aviation screw used to fasten, secure, or retain components during assembly of the airframe. It fits the Citation Longitude, King Air B200, B200T, B200C or B200CT, King Air B200GT, King Air B200GT Fusion or B200CGT Fusion, King Air C90, C90A, C90GT or E90, King Air C90GTi, and King Air C90GTx. It carries an export classification of ECCN EAR99. Because the MS21318-13 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 Cessna Citation and Beechcraft King Air aircraft share extensive structure and hardware, a single part like this is often common across several variants. Strength grade and finish define aircraft hardware, so matching the specified part keeps the joint as designed. For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide. These aircraft are built by Textron Aviation, which unites Cessna (founded 1927) and Beechcraft (founded 1932) under one Wichita, Kansas company since 2014. The Citation family is the best-selling line of business jets ever built, and more than 7,500 have been delivered worldwide.
