Description
The MS21442-121 is a genuine Textron Aviation bearing that supports rotational or pivoting motion within a mechanism. It fits the Caravan or Grand Caravan EX, Citation Latitude, and Citation Sovereign or Sovereign+. It carries an export classification of ECCN EAR99, weighs 0.05 lbs, and measures 0.76 (L) x 0.76 (W) x 0.57 (H) in.
Because the MS21442-121 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.
Fit and load rating define a bearing's job, so matching the specified part protects both function and service life. Because aircraft parts are governed by strict airworthiness and traceability rules, fitting the OEM part rather than an unapproved equivalent keeps the installation eligible and the aircraft's records clean.
Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
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.
