Description
The 0511039-6 is a genuine Textron Aviation right-hand root rib — an internal structural member that helps define the airframe's shape and carry its loads. It fits the Skyhawk. It carries an export classification of ECCN 9A991, weighs 0.99 pounds, and measures 35.25 (L) x 10.2 (W) x 0.85 (H) Inches.
As an original-equipment (OEM) structural part supplied directly by Textron Aviation, the 0511039-6 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 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.
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.
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.
