Description
The MS24399-6D 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 fitted to the Citation III, VI or VII. It carries an export classification of ECCN 9A991.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the MS24399-6D meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Across the Cessna Citation fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
This is a cataloged factory part whose form, fit, and function are established by the manufacturer's approved data. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger.
For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
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. The Citation family is the best-selling line of business jets ever built, and more than 7,500 have been delivered worldwide.
