Description
The 0511785-1 is a genuine Textron Aviation aileron control chain sprocket supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It is applicable to the Skyhawk. It carries an export classification of ECCN 9A991.
Because the 0511785-1 is an original-equipment (OEM) part sourced directly from Textron Aviation, it matches the exact specification and placement called out in the aircraft's type design and maintenance data — assurance a generic substitute cannot offer.
Because the Cessna Skyhawk aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Supplied as a defined part in the manufacturer's catalog, its exact role is set by the aircraft's parts and maintenance data. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
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 value of an OEM part is as much in its paperwork and pedigree as its metal — both of which an aircraft's records require.
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. The Cessna 172 Skyhawk is the most-produced aircraft in history, with more than 44,000 built since 1956, and remains in production under Textron Aviation.
