GROMMET, PLASTIC, EDGING

The MS21266-8N is a genuine Textron Aviation grommet plastic edging that seals a joint or opening against air, fluid, or contamination. It fits the 1900 Airliner, 1900C Airliner, 1900D Airliner, King Air 350 Fusion, King Air 350C FM-36 & On, King Air 350C Fusion, King Air 350i, King Air 360, King Air 360C, and King Air B200, B200T, B200C or B200CT, among other compatible variants. It carries an export classification of ECCN EAR99, weighs 0.03 lbs, and measures 7.5 (L) x 0.45 (W) x 0.27 (H) in. As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21266-8N is built to the aircraft maker's specification and cross-references the type design as documented in the maintenance data. Choosing the genuine part over an unapproved substitute preserves configuration control and simplifies inspection sign-offs. Across the Beechcraft 1900, King Air, and Premier fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. Material and dimensions make a seal work; the correct factory part is what keeps the joint from leaking in service. Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance. Beechcraft, founded in Wichita, Kansas in 1932, joined Cessna and Hawker under Textron Aviation in 2014, which today supports the worldwide Beechcraft fleet with genuine factory parts. Derived from the King Air, the 19-passenger Beechcraft 1900 airliner (built 1982–2002) remains in service with regional and cargo operators.
