STIFFENER

The 0513503-2 is a genuine Textron Aviation stiffener — a formed reinforcing member that adds rigidity and helps distribute structural loads. It is applicable to the Skyhawk. It carries an export classification of ECCN 9A991. As an original-equipment (OEM) structural part supplied directly by Textron Aviation, the 0513503-2 is manufactured to the aircraft maker's specification for material, dimensions, and finish, and cross-references the type design exactly as documented in the maintenance data. For a structural member, the genuine correctly identified part preserves the engineered load paths and keeps the airframe configuration-correct. 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. Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance. 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. With over 44,000 built, the Cessna Skyhawk is the best-selling aircraft ever made and is still produced today. Request a quote for 0513503-2 or browse more Cessna Skyhawk parts on Flying411.
