On December 16, 2010, at 1100 Central Standard Time, a Cessna T182T, N2187H, sustained substantial damage when it nosed over during landing at the Quad Cities International Airport (MLI), Moline, Illinois. The commercial pilot and passenger received minor injuries. The 14 Code of Federal Regulations Part 91 flight departed Midway Airport (MDW) at 1000. Visual meteorological conditions prevailed at the time of the accident. An instrument flight plan was filed. The pilot reported that he attempted to land on the right side of the runway centerline since it had the least amount of snow. He reported that the airplane veered to the right during the landing roll and he was unable to prevent it from going off the runway. The airplane nosed over and came to rest inverted on the right side of the runway, resulting in substantial damage. The right seat passenger confirmed that the airplane landed on the right side of the runway and veered off the right side. He reported that the windshield was clear and that the runway was visible. Witnesses reported that the airplane was found about 75 feet from edge of the runway. They reported that there were three tracks through the snow that were about 150 feet in length that were parallel to the runway and led to the airplane. They did not observe tracks that veered off the runway and led to the airplane. The witnesses reported that about 1/8 inch of rime ice covered the airplane's windshield and leading edge of the wings. A runway friction test conducted shortly after the accident indicated that the runway conditions were normal. The inspection of the airplane's flight controls and brakes revealed no anomalies. The pilot reported that there was no mechanical malfunction or failure of the airplane. A non-DOT drug screen directed by the pilot's company indicated a positive result for amphetamines in the pilot's urine. It was not possible to determine from the toxicological test of the urine whether the pilot was impaired as a result of the medication at the time of the accident.
