Airworthiness Directives; Bombardier Model BD-100-1A10 Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model BD-100-1A10 airplanes. This AD requires an inspection for signs of arcing or heat damage of the electrical connections of the terminal blocks, ground studs, and the end of the wires and surrounding insulation for the windshield and side window anti-ice systems; and repairing any arced or damaged electrical connection. This AD also requires re-torquing electrical connections of the terminal blocks and ground studs for the windshield and side window anti-ice systems. 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.
