DOUBLER

The 0522639-7 is a genuine Textron Aviation doubler used to reinforce and locally strengthen a skin or structural member. It is fitted to the Skyhawk. It carries an export classification of ECCN 9A991. Because the 0522639-7 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. Structural parts like this carry and transfer loads through the airframe, so exact form and fit are essential to preserving the design's strength and fatigue life. 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. For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation. Built by Textron Aviation, whose Cessna line was founded in Wichita, Kansas in 1927 and joined Textron in 1992, this part carries one of general aviation's most storied names. 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.
