Description
The MS21905D8 is a genuine Textron Aviation tee supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It is applicable to the Citation X, Citation X+, and Premier Model 390. It carries an export classification of ECCN 9A991.
Because the MS21905D8 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.
Because the Cessna Citation and Beechcraft Premier aircraft share extensive structure and hardware, a single part like this is often common across several variants.
As a load-bearing element, a part in this role must match the original material and dimensions precisely to keep the airframe's engineered strength intact. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide.
Using the factory part number preserves configuration control, so the airframe stays consistent with its approved type design and the work is straightforward to sign off at inspection.
These aircraft are built by Textron Aviation, which unites Cessna (founded 1927) and Beechcraft (founded 1932) under one Wichita, Kansas company since 2014. The Citation family is the best-selling line of business jets ever built, and more than 7,500 have been delivered worldwide.
