DOUBLER ASSY

The S1443-1 is a genuine Textron Aviation doubler assembly used to reinforce and locally strengthen a skin or structural member. It is applicable to the Skyhawk. It carries an export classification of ECCN 9A991, weighs 0.06 pounds, and measures 5.95 (L) x 5.5 (W) x 0.15 (H) Inches. Because the S1443-1 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. Parts like this are shared across the Cessna Skyhawk aircraft, reflecting how much structure and hardware these models have in common. 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. Using the factory part number preserves configuration control, so the airframe stays consistent with its approved type design and the work is straightforward to sign off at inspection. The value of an OEM part is as much in its paperwork and pedigree as its metal — both of which an aircraft's records require. 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.
