Description
The 3940475-2 is a genuine Textron Aviation elevator trim cable assembly of a type used to carry current or signals through the aircraft. It is fitted to the Skyhawk. It carries an export classification of ECCN 9A991.
Because the 3940475-2 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.
Because the Cessna Skyhawk aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Ratings, tolerances, and interfaces are what define an electrical part; matching the specified item keeps the system working as certified. Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application.
Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated. 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.
