On January 6, 2010, at 0635 central standard time, a Beech C-99, N206AV, was substantially damaged during a hard landing at Kearney Municipal Airport (EAR), Kearney, Nebraska. The commercial pilot was not injured. The non-scheduled cargo flight, operated by Ameriflight, LLC., was conducted under the provisions of 14 Code of Federal Regulations Part 135 with an Instrument Flight Rules (IFR) flight plan. The cross-country flight originated at Eppley Airfield (OMA), Omaha, Nebraska, and was en route to EAR. According to the pilot, the airplane picked up light to moderate icing during the approach and he cycled the deicing boots once prior to the final approach fix. The pilot reported that he was established on the instrument landing system (ILS) approach to runway 36 at 120 knots indicated airspeed, configured with landing gear down, and 30 percent flaps, when he broke out of the weather about 250 feet above ground level. The pilot estimated that the approach brought the airplane 60 feet right of the runway centerline so he made a correction to align the airplane with the runway. The pilot continued that when the airplane was wings level and about 25 feet above the runway the left wing stalled and the airplane landed hard on the left main landing gear, bending the rear spar of the left wing. During the postflight inspection of the airplane there was 3/8 to 1/2 inch of ice observed on portions of the airplane’s wings, including the leading edge surfaces of the deicing boots. The pilot further reported that he did not recall the stall warning horn activating during the approach. Weather at EAR at 0635 was reported as 21 degrees Fahrenheit (F), dew point 19 degrees F, visibility ½ mile with freezing fog, ceiling 200 feet overcast, and winds from 130 degrees at 4 knots. The STALL WARN POWER circuit breaker was found popped during the postaccident inspection. The cause of the popped circuit breaker could not be determined. An examination of the remaining systems revealed no anomalies.
