WASHER

The S1438-17 is a genuine Textron Aviation washer 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, Skylane, and Stationair. It carries an export classification of ECCN 9A991. Supplied directly by Textron Aviation as an original-equipment (OEM) part, the S1438-17 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records. Across the Cessna Caravan, Citation, Skyhawk, Skylane, and Stationair fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger. Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated. The Cessna name is among the most recognized in aviation — founded in Wichita, Kansas in 1927 and part of Textron since 1992, today a cornerstone of Textron Aviation. Cessna's single-engine Caravan turboprop, in production since 1984, is one of the most widely used utility aircraft in the world.
