Description
The AV4081-2 is a genuine Textron Aviation air valve — a flow-control element for a fluid or pneumatic system. It is fitted to the Skyhawk and Skylane. It carries an export classification of ECCN EAR99.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the AV4081-2 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Because the Cessna Skyhawk and Skylane aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Parts in a fluid or pneumatic system must match the specified ratings and connections to function reliably under pressure. 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.
Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value. Using the factory part number preserves configuration control, so the airframe stays consistent with its approved type design and the work is straightforward to sign off at inspection.
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.
