Description
The 0552170-3 is a genuine Textron Aviation stiffener — a formed reinforcing member that adds rigidity and helps distribute structural loads. It fits the Skyhawk. It carries an export classification of ECCN 9A991, weighs 0.17 pounds, and measures 32.75 (L) x 1.35 (W) x 0.5 (H) Inches.
As an original-equipment (OEM) structural part supplied directly by Textron Aviation, the 0552170-3 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.
Across the Cessna Skyhawk fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
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.
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.
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. With over 44,000 built, the Cessna Skyhawk is the best-selling aircraft ever made and is still produced today.
