Description
The AV4033-1 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 and Skylane. It carries an export classification of ECCN EAR99.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the AV4033-1 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Across the Cessna Skyhawk and Skylane 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 substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application.
Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance. 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.
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. With over 44,000 built, the Cessna Skyhawk is the best-selling aircraft ever made and is still produced today.
