REDUCER

The MS21916V10-6P is a genuine Textron Aviation reducer supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It fits the Citation III, VI or VII and Citation Sovereign or Sovereign+. It carries an export classification of ECCN EAR99. Because the MS21916V10-6P 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. Parts like this are shared across the Cessna Citation aircraft, reflecting how much structure and hardware these models have in common. As a factory-supplied item for a type-certificated aircraft, this part is defined by the manufacturer's specification and applicability data. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value. Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated. 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 Citation line, launched with the Model 500 in the early 1970s, grew into the best-selling business-jet family in the world, spanning today from the light M2 to the super-midsize Longitude.
