GROMMET

The MS21266-2T is a genuine Textron Aviation grommet that seals a joint or opening against air, fluid, or contamination. It is applicable to the Baron Series B55, E55, 58 or G58, Beechjet 400/400A, Citation Excel, XLS, XLS+, XLS Gen 2, Citation Latitude, Citation Sovereign or Sovereign+, Citation V, Ultra, Encore or Encore+, Citation X, Citation X+, and Premier Model 390. It carries an export classification of ECCN 9A991, weighs 0.02 pounds, and measures 9.15 (L) x 3.8 (W) x 0.2 (H) Inches. As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21266-2T 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. Parts like this are shared across the Beechcraft Baron, Beechcraft, Cessna Citation, and Beechcraft Premier aircraft, reflecting how much structure and hardware these models have in common. 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. These aircraft are built by Textron Aviation, which unites Cessna (founded 1927) and Beechcraft (founded 1932) under one Wichita, Kansas company since 2014. The Baron — a twin-engine member of Beechcraft's piston line introduced in 1961 — shares much of its structure and hardware with the Bonanza.
