On July 2, 1998, at 1930 mountain daylight time, a Cessna 182N, N92519, registered to and operated by Interstate Aviation as a 14 CFR Part 91 personal flight, ran off the side of the airstrip at Big Creek, Idaho, and collided with a fence. Visual meteorological conditions prevailed at the time and no flight plan was filed. The airplane was substantially damaged and the private pilot and one passenger were not injured. The other two passengers received minor injuries. The flight had originated from Lewiston, Idaho, about one hour prior to the accident. In a written statement, the pilot reported that he over flew the runway twice before setting up an approach to runway 19. The pilot stated that he was high on the final approach and slipped the airplane to descend. The airplane landed within the first 1/3 of the length of the runway in a full stall on the main landing gear. The pilot stated that the touch down was on the left side of centerline due to cones that were placed on the airstrip. The pilot reported that from the point of touchdown to impact with the fence, the airplane was gradually sliding to the left. The pilot tried to correct with right rudder control and braking action, however, the airplane continued to the left and collided with a fence. The pilot stated that the airstrip surface (grass) was wet and rougher than what he remembered from previous flights into this airstrip. The pilot reported that there were no mechanical failures or malfunctions with the airplane at the time of the accident. The Big Creek Airstrip is 3,550 feet in length with a turf surface. Landing is recommended to the south.
