Description
The S3431-3A is a genuine Textron Aviation nutplate supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It is fitted to the Skyhawk and Skylane. It carries an export classification of ECCN EAR99, weighs 0.03 pounds, and measures 0.9 (L) x 0.45 (W) x 0.15 (H) Inches.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the S3431-3A 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.
Parts like this are shared across the Cessna Skyhawk and Skylane aircraft, reflecting how much structure and hardware these models have in common.
This is a cataloged factory part whose form, fit, and function are established by the manufacturer's approved data. 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.
Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide.
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.
