TEE

The MS24389D4 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 1900 Airliner, 1900C Airliner, 1900D Airliner, and Citation Excel, XLS, XLS+, XLS Gen 2. It carries an export classification of ECCN EAR99. Supplied directly by Textron Aviation as an original-equipment (OEM) part, the MS24389D4 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records. Because the Beechcraft 1900 and Cessna Citation aircraft share extensive structure and hardware, a single part like this is often common across several variants. 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. Because aircraft parts are governed by strict airworthiness and traceability rules, fitting the OEM part rather than an unapproved equivalent keeps the installation eligible and the aircraft's records clean. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value. 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. Derived from the King Air, the 19-passenger Beechcraft 1900 airliner (built 1982–2002) remains in service with regional and cargo operators.
