On Friday afternoon, September 3, 1993, at 1349 mountain daylight time, a Cessna C-182L, N42708, registered to the pilot, swerved off the runway and impacted terrain while landing at Idaho Falls, Idaho. A VFR flight plan was filed for the personal flight, operated under 14 CFR 91 in visual meteorological conditions, that departed Salt Lake City, Utah, at 1220, September 3, 1993. The private certificated pilot and the three passengers aboard were not injured. The aircraft was substantially damaged. There was no fire. The pilot reported the aircraft veered sharply off the right side of runway 20 during landing roll, impacted a ditch, and nosed over. The airport tower controller on duty at the time of the accident stated in the initial notification telephone call that dust devils were moving across the airport when the accident occurred. The pilot wrote in the Pilot/Operator Report that an observer in the FAA Flight Service Station told him that dust from the plane swirled up in a circular motion after the impact and that a pilot who landed just before the accident had observed a dust devil near the runway. The surface aviation weather observation, taken at the airport at the time of the accident, was recorded as clear skies, visibility 50 miles, temperature 78 degrees F., dew point 37 degrees F., wind 250 degrees at seven knots and altimeter 30.28 inches Hg.
