On July 2, 2000, about 1230 Alaska daylight time, a float equipped Cessna 182 airplane, N9013G, sustained substantial damage during takeoff from a remote river site, about 1 mile south of New Stuyahok, Alaska, at latitude 59 degrees, 26 minutes north, and longitude 157 degrees, 19 minutes west. The airplane was being operated as a visual flight rules (VFR) personal flight under Title 14, CFR Part 91, when the accident occurred. The certificated private pilot was not injured. Visual meteorological conditions prevailed, and no flight plan was filed. During a telephone conversation with the National Transportation Safety Board investigator-in-charge on July 11, the pilot reported that as he started the northeasterly, down river takeoff run, the winds increased to 15 or 20 knots out of the southeast, and the airplane veered to the left. He said that as he applied right rudder to correct the veer, the right wing lifted, and both floats struck the left-hand side of the riverbank. The airplane nosed over, and sustained substantial damage to the wings and vertical stabilizer. The pilot said that there were no preaccident mechanical anomalies with the airplane.
