Rear Spar Forward Doubler

The 0523042-1 is a genuine Textron Aviation rear spar forward doubler that forms part of the wing's primary load-carrying structure. It is applicable to the Skyhawk. It carries an export classification of ECCN 9A991. Because the 0523042-1 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. Across the Cessna Skyhawk fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. As a load-bearing element, a part in this role must match the original material and dimensions precisely to keep the airframe's engineered strength intact. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation. 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. 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 Cessna name is among the most recognized in aviation — founded in Wichita, Kansas in 1927 and part of Textron since 1992, today a cornerstone of Textron Aviation. 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.
