Description
The 0543001-0 is a genuine Textron Aviation ferrule axle bolt — a fastening or retaining hardware item used in the airframe. It is applicable to the Skyhawk. It carries an export classification of ECCN 9A991.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the 0543001-0 is built to the aircraft maker's specification and cross-references the type design as documented in the maintenance data. Choosing the genuine part over an unapproved substitute preserves configuration control and simplifies inspection sign-offs.
Parts like this are shared across the Cessna Skyhawk aircraft, reflecting how much structure and hardware these models have in common.
Because gear components see repeated high stress, their material and condition are tightly specified — the right part matters for safety. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger.
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.
