Description
The 0542118-5 is a genuine Textron Aviation piston assembly supplied as a built-up assembly of several components in a single installable unit. It is fitted to the Skyhawk. It carries an export classification of ECCN 9A991.
Because the 0542118-5 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.
Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation. Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections.
On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front.
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. 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.
