Description
The 3940453-4 is a genuine Textron Aviation cable assembly of a type used to carry current or signals through the aircraft. It is applicable to the Skyhawk. It carries an export classification of ECCN 9A991, weighs 0.02 pounds, and measures 0.5 (L) x 5.95 (W) x 0.35 (H) Inches.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the 3940453-4 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.
Ratings, tolerances, and interfaces are what define an electrical part; matching the specified item keeps the system working as certified. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide.
The factory part is built to the manufacturer's material and dimensional specification, so it installs as designed without the surprises a generic equivalent can bring. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
Cessna traces to the company Clyde Cessna founded in Wichita, Kansas in 1927; Textron Inc. acquired it in 1992, and since 2014 it has anchored Textron Aviation alongside Beechcraft and Hawker. With over 44,000 built, the Cessna Skyhawk is the best-selling aircraft ever made and is still produced today.
