On September 30, 2005, about 2115 Alaska daylight time, a wheel-equipped Cessna 182 airplane, N3569Y, sustained substantial damage when it overran the end of the runway and nosed over at a remote airstrip about 60 miles east-southeast of Bethel, Alaska. The airline transport certificated pilot and the sole passenger were not injured. The 14 CFR Part 91 personal flight departed Bethel about 2030, and the destination was the accident airstrip. No flight plan was filed, and the pilot reported visual meteorological conditions prevailed. During a telephone conversation with the NTSB investigator-in-charge on October 3, the pilot related that he and his son, the passenger, were en route to the remote airstrip for a camping/hunting trip. He said he left Bethel too late, and by the time he arrived at the airstrip, it was getting dark. He stated that because of the dark sky, he misjudged his landing, and landed too far down the airstrip. He was unable to stop the airplane, and it went off the end of the runway and nosed over. The pilot said that there were no preaccident mechanical problems with the airplane.
