GROMMET

The MS21266-7N is a genuine Textron Aviation grommet used to keep a joint or pass-through tight. It fits the Citation V, Ultra, Encore or Encore+ and Premier Model 390. It carries an export classification of ECCN 9A991 and measures 12 (L) x 1 (W) x 1 (H) Inches. Supplied directly by Textron Aviation as an original-equipment (OEM) part, the MS21266-7N meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records. Parts like this are shared across the Cessna Citation and Beechcraft Premier aircraft, reflecting how much structure and hardware these models have in common. Sealing components are sized and compounded for the fluids, temperatures, and pressures they contain, so the exact specified part maintains a tight joint. 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. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value. 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.
