Description
The OHCW4SM6DS15BN is a genuine Textron Aviation screw assembly — a fastening or retaining hardware item used in the airframe. It is fitted to the Skyhawk. It carries an export classification of ECCN 9A991.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the OHCW4SM6DS15BN meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Because the Cessna Skyhawk 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.
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. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
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.
