Description
The 0553031-3 is a genuine Textron Aviation firewall assembly lower supplied as a built-up assembly of several components in a single installable unit. It fits the Skyhawk. It carries an export classification of ECCN 9A991.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the 0553031-3 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
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.
Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections. 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.
An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk.
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.
