AIR VALVE

The AV4080-1 is a genuine Textron Aviation air valve that controls the flow of fluid or air within an aircraft system. It fits the Skyhawk. It carries an export classification of ECCN EAR99. As an original-equipment (OEM) part supplied directly by Textron Aviation, the AV4080-1 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. Across the Cessna Skyhawk fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. Parts in a fluid or pneumatic system must match the specified ratings and connections to function reliably under pressure. Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger. 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 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.
