Description
The MS21905-4T is a genuine Textron Aviation tee supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It fits the Citation Longitude and Citation Sovereign or Sovereign+. It carries an export classification of ECCN 9A991, weighs 0.05 pounds, and measures 1.75 (L) x 1.1 (W) x 0.5 (H) Inches.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21905-4T 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.
Parts like this are shared across the Cessna Citation aircraft, reflecting how much structure and hardware these models have in common.
Airframe structure of this kind is engineered to specific load paths; the correct part is what keeps those paths — and the aircraft's certified strength — unchanged. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide.
Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger.
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.
