RESISTOR DIMMING ASSEMBLY

The S2091-9 is a genuine Textron Aviation resistor dimming assembly of a type used within the aircraft's avionics or electrical circuits. It fits the Skyhawk and Skylane. It carries an export classification of ECCN EAR99, weighs 0.07 lbs, and measures 1.9 (L) x 1.1 (W) x 1.2 (H) in. Because the S2091-9 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 and Skylane fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. In an aircraft's electrical system, using the correct component preserves the circuit's designed behavior, reliability, and safety. For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for. Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections. 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. Request a quote for S2091-9 or browse more Cessna Skyhawk and Skylane parts on Flying411.
