REDUCER

The MS24397D2 is a genuine Textron Aviation reducer supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It is applicable to the Citation CJ1 or CJ1+, Citation CJ2 or CJ2+, Citation Excel, XLS, XLS+, XLS Gen 2, Citation III, VI or VII, and Citation V, Ultra, Encore or Encore+. It carries an export classification of ECCN 9A991. As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS24397D2 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 Citation fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. As a factory-supplied item for a type-certificated aircraft, this part is defined by the manufacturer's specification and applicability data. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front. 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. The Citation family is the best-selling line of business jets ever built, and more than 7,500 have been delivered worldwide.
