TEE

The MS21905J4 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 III, VI or VII, Citation X, Citation X+, and Premier Model 390. It carries an export classification of ECCN 9A991. Because the MS21905J4 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. Structural parts like this carry and transfer loads through the airframe, so exact form and fit are essential to preserving the design's strength and fatigue life. The factory part is built to the manufacturer's material and dimensional specification, so it installs as designed without the surprises a generic equivalent can bring. Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated. Both the Cessna and Beechcraft lines are supported today by Textron Aviation, formed in 2014 to unite the two historic Wichita manufacturers with 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.
