NUT

The MS21245-L10 is a genuine Textron Aviation nut used to fasten, secure, or retain components during assembly of the airframe. It fits the Caravan or Grand Caravan EX and Citation CJ4, CJ4 Gen 2, CJ4 Gen 3. It carries an export classification of ECCN 9A991, weighs 0.04 pounds, and measures 1 (L) x 0.9 (W) x 0.4 (H) Inches. Because the MS21245-L10 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 Cessna Caravan and Citation fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. Aircraft hardware is called out to a specific specification for each location; an off-the-shelf equivalent is rarely acceptable. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger. Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide. Built by Textron Aviation, whose Cessna line was founded in Wichita, Kansas in 1927 and joined Textron in 1992, this part carries one of general aviation's most storied names. Cessna's single-engine Caravan turboprop, in production since 1984, is one of the most widely used utility aircraft in the world.
