Description
The CM3558-4-8B is a genuine Textron Aviation screw — a fastening or retaining hardware item used in the airframe. It fits the Citation CJ3, CJ3+, CJ3+ Gen 2, CJ3 Gen 3, Citation M2, M2 Gen 2, M2 Gen 3, Skyhawk, Skylane, and Stationair. It carries an export classification of ECCN EAR99.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the CM3558-4-8B meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Across the Cessna Citation, Skyhawk, Skylane, and Stationair fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
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.
Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger.
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.
