TEE

The MS24389-4 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 1900 Airliner and 1900C Airliner. Because the MS24389-4 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 Beechcraft 1900 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 this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk. The value of an OEM part is as much in its paperwork and pedigree as its metal — both of which an aircraft's records require. Built by Beechcraft — the Wichita, Kansas manufacturer founded in 1932 and part of Textron Aviation since 2014 — this part carries a name long associated with rugged, capable aircraft. Derived from the King Air, the 19-passenger Beechcraft 1900 airliner (built 1982–2002) remains in service with regional and cargo operators.
