STIFFENER-LH

The 0512028-5 is a genuine Textron Aviation left-hand 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. As an original-equipment (OEM) structural part supplied directly by Textron Aviation, the 0512028-5 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. Parts like this are shared across the Cessna Skyhawk aircraft, reflecting how much structure and hardware these models have in common. 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. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk. 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. 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. With over 44,000 built, the Cessna Skyhawk is the best-selling aircraft ever made and is still produced today. Request a quote for 0512028-5, or browse more Cessna Skyhawk parts on Flying411.
