On March 20, 2008, about 0100 mountain daylight time, a Beech F90, N124BK, had the nose gear collapse during a landing overrun at Idaho Falls, Idaho. The pilot/owner was operating the airplane under the provisions of 14 Code of Federal Regulations (CFR) Part 91. The certificated private pilot and five passengers were not injured. The airplane sustained substantial damage to the airframe in the nose wheel well. The personal cross-country flight departed Salt Lake City, Utah, with a final destination of Idaho Falls. Visual meteorological conditions prevailed, and an instrument flight rules (IFR) flight plan had been filed. The pilot stated that he flew IFR from Salt Lake City to Idaho Falls. He cancelled IFR about 25 miles from Idaho Falls, and proceeded under visual conditions. He decided to land on runway 35. The pilot stated that he was high and fast as he crossed the numbers. At touchdown and reverse thrust, he didn't like what he was experiencing, so he added power to abort the landing. It took the engines 1 to 2 seconds to spool up, and he decided that it would be better to roll off the end of the runway than to attempt a takeoff with so little runway left. He went back into reverse thrust. He did not apply full brakes, as he was concerned that the airplane might flip over. The airplane went off the end of the runway, and slid to a stop in snow and mud. The nose gear collapsed in the process. The pilot shut the engines down, and verified that his passengers were not injured. They evacuated the airplane, and went to the hangar. The pilot stated that he had planned for the late hour arrival by resting during the day. He was alert and in good health. The runway was clear and dry, with excellent braking conditions. The airplane had come out of a phase check recently, and there were no squawks; the engines ran great.
