This AD results from an in-service incident involving smoke and odor in the cockpit. We are issuing this AD to prevent loose electrical connections that could arc and overheat, and cause wiring damage of the windshield and side window anti-ice systems. Such wiring damage could result in smoke and/or fire in the flight compartment.
