Description
The 3940458-4 is a genuine Textron Aviation bracket — a support fitting that secures or positions a component in the airframe. It fits the Skyhawk. It carries an export classification of ECCN 9A991.
Because the 3940458-4 is an original-equipment (OEM) part sourced directly from Textron Aviation, it matches the exact specification and placement called out in the aircraft's type design and maintenance data — assurance a generic substitute cannot offer.
Because the Cessna Skyhawk aircraft share extensive structure and hardware, a single part like this is often common across several variants.
A support or bracket component holds a system or structure in its correct place, so the right part preserves alignment and clearance. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk.
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.
