Description
The MS21086-3 is a genuine Textron Aviation nutplate supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It fits the Citation CJ4, CJ4 Gen 2, CJ4 Gen 3, Citation Longitude, Citation M2, M2 Gen 2, M2 Gen 3, Citation Sovereign or Sovereign+, Citation X+, Skyhawk, and Stationair. It carries an export classification of ECCN EAR99.
Because the MS21086-3 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.
Across the Cessna Citation, Skyhawk, and Stationair fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
Supplied as a defined part in the manufacturer's catalog, its exact role is set by the aircraft's parts and maintenance data. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk.
Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections.
Cessna traces to the company Clyde Cessna founded in Wichita, Kansas in 1927; Textron Inc. acquired it in 1992, and since 2014 it has anchored Textron Aviation alongside Beechcraft and 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.
