TEE

The MS21909D6 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 fitted to the Citation III, VI or VII and Citation V, Ultra, Encore or Encore+. It carries an export classification of ECCN 9A991. Supplied directly by Textron Aviation as an original-equipment (OEM) part, the MS21909D6 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records. Because the Cessna Citation 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. 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. 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. Cessna's Citation line, launched with the Model 500 in the early 1970s, grew into the best-selling business-jet family in the world, spanning today from the light M2 to the super-midsize Longitude.
