Description
The 0511039-4 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 1.16 pounds, and measures 35.35 (L) x 10.65 (W) x 0.85 (H) Inches.
As an original-equipment (OEM) structural part supplied directly by Textron Aviation, the 0511039-4 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.
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. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger.
For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for.
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.
