Description
The 3940389-2 is a genuine Textron Aviation aft fan cover that moves air for cooling or ventilation within a system or compartment. It is fitted to the Skyhawk. It carries an export classification of ECCN 9A991, weighs 0.08 pounds, and measures 4.7 (L) x 4.6 (W) x 1.9 (H) Inches.
Because the 3940389-2 is an original-equipment (OEM) part sourced directly from Textron Aviation, it matches the exact specification and placement called out in the aircraft's type design and maintenance data — assurance a generic substitute cannot offer.
Across the Cessna Skyhawk fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
A covering part like this is contoured to the structure, so the right one maintains both fit and the smooth external surface. 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.
Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
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.
