Description
The MS21902W16 is a genuine Textron Aviation union supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It is applicable to the Citation Longitude. It carries an export classification of ECCN 9A991.
Because the MS21902W16 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.
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.
On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front. Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application.
Cessna traces to the company Clyde Cessna founded in Wichita, Kansas in 1927; Textron Inc. acquired it in 1992, and since 2014 it has anchored Textron Aviation alongside Beechcraft and Hawker. The Citation family is the best-selling line of business jets ever built, and more than 7,500 have been delivered worldwide.
