On July 24, 2004, at approximately 1630 mountain daylight time, a Cessna 182N, N92824, was substantially damaged when it landed long, overran the runway, and impacted trees. The private pilot was not injured. The pilot/owner was operating the airplane under Title 14 CFR Part 91. Visual meteorological conditions prevailed for the cross-country personal flight that originated from Saco, Montana, approximately one hour before the accident. The pilot had not filed a flight plan. The pilot said he over-flew the private field twice to check its condition. He flew a traffic pattern, and on final realized that he was "high." He slipped the airplane to lose altitude, and put down 40 degrees of flaps. He said the airplane floated, and subsequently landed long. He "went off [the] end of the runway, bounced across uneven ground, and hit trees w/right wing." He said the right wing and fuselage were bent, and the engine's fire wall was wrinkled.
