On October 29, 1998, at 1920 central standard time, a Cessna C-182, N2291G, operated by the Lincoln Sport Parachute Club, was substantially damaged when it nosed over during the landing roll. The commercial pilot was not injured. The pilot reported that the airplane veered off the runway after the right wheel of the airplane hit a rut in the grass airstrip. The airplane went through a corner of a bean field, but was brought back onto the crossing runway. The nose gear hit a rut and the airplane nosed over. The 14 CFR Part 91 flight had departed Browns Airport in Weeping Water, Nebraska, on a local flight. Visual meteorological conditions prevailed and no flight plan was filed. The pilot reported that he was doing a night landing to a grass airstrip that had two lights at the approach end of runway 17. There were no other lights marking runway 17. The pilot reported that directional control was maintained until the right wheel hit a rut in the runway. He reported the airplane went airborne and veered off the right side of the runway. The airplane went through a harvested bean field and nosed over when the nose gear hit a rut on the crossing runway. The pilot reported there was nothing wrong with the airplane prior to the accident.
