Description
The AV4080-2 is a genuine Textron Aviation air valve that controls the flow of fluid or air within an aircraft system. It is fitted to the Skyhawk. It carries an export classification of ECCN EAR99.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the AV4080-2 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.
Because the Cessna Skyhawk aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Because it handles pressurized fluid or air, a component like this is specified precisely for its service — the right part keeps the system sound. 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.
Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk.
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. With over 44,000 built, the Cessna Skyhawk is the best-selling aircraft ever made and is still produced today.
