Description
The S2389-2 is a genuine Textron Aviation washer — a fastening or retaining hardware item used in the airframe. It is applicable to the Skyhawk. It carries an export classification of ECCN 9A991, weighs 0.01 pounds, and measures 0.9 (L) x 0.9 (W) x 0.05 (H) Inches.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the S2389-2 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 Skyhawk aircraft, reflecting how much structure and hardware these models have in common.
Strength grade and finish define aircraft hardware, so matching the specified part keeps the joint as designed. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk.
Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front.
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. The Cessna 172 Skyhawk is the most-produced aircraft in history, with more than 44,000 built since 1956, and remains in production under Textron Aviation.
