CLIP NUT

The S4213-16 is a genuine Textron Aviation clip nut — a fastening or retaining hardware item used in the airframe. It fits the Skyhawk and Skylane. It carries an export classification of ECCN EAR99, weighs 0.01 pounds, and measures 0.6 (L) x 0.45 (W) x 0.15 (H) Inches. Supplied directly by Textron Aviation as an original-equipment (OEM) part, the S4213-16 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records. Because the Cessna Skyhawk and Skylane aircraft share extensive structure and hardware, a single part like this is often common across several variants. Aircraft hardware is called out to a specific specification for each location; an off-the-shelf equivalent is rarely acceptable. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk. For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for. 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. 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.
