On July 10, 2006, approximately 1045 mountain daylight time, a Cessna Citation 560, N50CV, encountered rough/soft terrain after it overran the end of the runway while landing at Ravalli County Airport, Hamilton, Montana. The airline transport pilot and his passenger were not injured, but the aircraft, which is owned and operated by River City Flying Service, sustained substantial damage. The 14 CFR Part 91 executive/corporate flight, which departed Visalia, California, at 0815 Pacific daylight time, was being operated in visual meteorological conditions on an instrument flight rules (IFR) flight plan.

According to witnesses, after the landing flare, the aircraft remained airborne and floated to a point about 1,500 feet down the 4,200 foot runway before touching down. Soon after touching down, the aircraft began to slow, but it did not stop until after it had departed the end of the runway, crossing over a grassy area and a ditch, and then entering a swamp.
