NUT

The S1477-8B is a genuine Textron Aviation nut used to fasten, secure, or retain components during assembly of the airframe. It fits the Caravan or Grand Caravan EX, Citation CJ1 or CJ1+, Citation CJ2 or CJ2+, Citation CJ3, CJ3+, CJ3+ Gen 2, CJ3 Gen 3, Citation M2, M2 Gen 2, M2 Gen 3, Skyhawk, and Stationair. It carries an export classification of ECCN EAR99. As an original-equipment (OEM) part supplied directly by Textron Aviation, the S1477-8B is built to the aircraft maker's specification and cross-references the type design as documented in the maintenance data. Choosing the genuine part over an unapproved substitute preserves configuration control and simplifies inspection sign-offs. Because the Cessna Caravan, Citation, Skyhawk, and Stationair aircraft share extensive structure and hardware, a single part like this is often common across several variants. Strength grade and finish define aircraft hardware, so matching the specified part keeps the joint as designed. Because aircraft parts are governed by strict airworthiness and traceability rules, fitting the OEM part rather than an unapproved equivalent keeps the installation eligible and the aircraft's records clean. 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 single-engine Caravan turboprop, in production since 1984, is one of the most widely used utility aircraft in the world.
