Hawker Beechcraft C99, Kearney, Neb., Jan. 6, 2010–The turboprop twin, operating under Part 135, was substantially damaged during a hard landing in IMC at Kearney Municipal Airport. The pilot reported that he cycled the de-icing boots before the final approach fix after noting light to moderate icing. When the aircraft was about 25 feet above the runway, “the left wing stopped flying” and the C99 landed hard on its left main landing gear, damaging the number-one propeller and the left wing rear spar. Post-flight inspection revealed between three-eighths and half an inch of ice on the wings.
