Description
The MS21245-L7 is a genuine Textron Aviation nut used to fasten, secure, or retain components during assembly of the airframe. It is fitted to the Caravan or Grand Caravan EX. It carries an export classification of ECCN EAR99, weighs 0.02 pounds, and measures 0.65 (L) x 0.65 (W) x 0.3 (H) Inches.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21245-L7 is built to the aircraft maker's specification and cross-references the type design as documented in the maintenance data. Choosing the genuine part over an unapproved substitute preserves configuration control and simplifies inspection sign-offs.
Across the Cessna Caravan fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide.
Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections. 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 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.
