KT-76C TRANSPONDER

The S3100-173 is a genuine Textron Aviation kt 76c transponder supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It is applicable to the Skyhawk and Skylane. It carries an export classification of ECCN 7A994. As an original-equipment (OEM) part supplied directly by Textron Aviation, the S3100-173 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. Because the Cessna Skyhawk and Skylane aircraft share extensive structure and hardware, a single part like this is often common across several variants. Supplied as a defined part in the manufacturer's catalog, its exact role is set by the aircraft's parts and maintenance data. 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. 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.
