Description
The CM3558-6-16B is a genuine Textron Aviation screw — a fastening or retaining hardware item used in the airframe. It is fitted to the Citation CJ3, CJ3+, CJ3+ Gen 2, CJ3 Gen 3, Citation M2, M2 Gen 2, M2 Gen 3, Skyhawk, and Skylane. It carries an export classification of ECCN EAR99.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the CM3558-6-16B 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, Skyhawk, and Skylane aircraft, reflecting how much structure and hardware these models have in common.
Aircraft hardware is called out to a specific specification for each location; an off-the-shelf equivalent is rarely acceptable. 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.
Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance.
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.
