Description
The 0511040-1 is a genuine Textron Aviation left-hand stiffener that reinforces a skin or spar and helps carry loads through the airframe. It is fitted to the Skyhawk. It carries an export classification of ECCN 9A991.
Because the 0511040-1 is an original-equipment (OEM) structural component from Textron Aviation, it is built to the airframe manufacturer's specification and matches the type design as documented. Fitting the genuine part preserves the wing or airframe's engineered strength and keeps installation and inspection records clean.
Because the Cessna Skyhawk aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Airframe structure of this kind is engineered to specific load paths; the correct part is what keeps those paths — and the aircraft's certified strength — unchanged. 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.
Because aircraft parts are governed by strict airworthiness and traceability rules, fitting the OEM part rather than an unapproved equivalent keeps the installation eligible and the aircraft's records clean.
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.
