Description
The MS21347-771 is a genuine Textron Aviation switch used to make or break an electrical circuit. It is applicable to the Citation V, Ultra, Encore or Encore+. It carries an export classification of ECCN EAR99.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the MS21347-771 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 aircraft, reflecting how much structure and hardware these models have in common.
Electrical and electronic components are defined by exact ratings and characteristics, so the specified part keeps the circuit performing as engineered. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
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. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk.
Built by Textron Aviation, whose Cessna line was founded in Wichita, Kansas in 1927 and joined Textron in 1992, this part carries one of general aviation's most storied names. 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.
