On October 14, 2004, about 1330 Pacific daylight time, a Cessna 182RG, N6071C, ran off the end of the runway during the landing roll at the Placerville Airport, Placerville, California. The pilot/owner was operating the airplane under the provisions of 14 CFR Part 91. The private pilot and one passenger sustained minor injuries; the airplane sustained substantial damage. The personal cross-country flight originated from the Van Nuys Airport, Van Nuys, California about 1130 with a planned destination of Placerville. Visual meteorological conditions prevailed, and a flight plan had not been filed. In a written statement, the pilot reported that while entering the vicinity of the airport, he noted several aircraft were in the pattern. The pilot continued onto final approach, and as the airplane passed over the runway threshold, it floated. Upon touch down, the airplane had traveled most of the length of the runway and the pilot applied brakes. While applying a substantial amount of brake pressure, the airplane skidded to the end of the runway and into soft dirt. The airplane continued on the dirt and went over an embankment, coming to rest inverted. During a telephone conversation with a Safety Board investigator, the pilot reported no pre-impact mechanical malfunctions or failures with the airplane. During the accident the airplane incurred damage to the wings, fuselage, propeller, and engine.
