Narrative:
Citation N50CV approached Ravalli County Airport following a 90-minute flight from Visalia (VIS).
The pilot reported that while he was executing a VFR extended straight-in approach to a full-stop landing, he encountered 10 knot wind fluctuations. He therefore decided to increase his approach speed by 10 knots. In addition to the increased airspeed, the pilot flew a flatter than normal approach descent angle. Due to the increased airspeed and the flatter approach, the airplane floated longer than normal after the initiation of the landing flare. Instead of executing a go-around after it became obvious that the airplane would not settle to the runway near the normal touchdown point, the pilot elected to continue the landing sequence. Once the airplane touched down, the pilot was unable to get it stopped in the remaining runway, and it departed the end of the runway and experienced a nose gear collapse after encountering rough/uneven, swampy terrain. The expected landing distance for the airplane was calculated based upon the Vref plus ten airspeed of 108 knots, a landing gross weight of 11,000 pounds, and the reported ambient weather conditions. According to those extrapolated calculations, the landing distance would have been expected to be about 3,100 feet. This distance does not include the use of thrust reversers.
Runway 34 is an asphalt runway, 4200 ft long.

Probable Cause:

PROBABLE CAUSE: "The pilot's failure to attain the proper touchdown point and to execute a go-around, which lead to an overrun of the runway surface. Contributing to the accident was his failure to maintain the correct landing approach speed (Vref), his failure to maintain the correct glide path, and the swampy and rough/uneven terrain the airplane encountered after departing the end of the runway."
