On May 23, 2004, at 1040 Pacific daylight time, a Smith RV-8, N767GS, collided with an object during the landing roll at Boulder City Municipal Airport, Boulder City, Nevada. The pilot/owner was operating the airplane under the provisions of 14 CFR Part 91. The airline transport pilot and single passenger were not injured, and the airplane was substantially damaged. Visual meteorological conditions prevailed, and no flight plan had been filed. The local flight originated at Boulder City at 1010. The pilot stated in the Pilot/Operator Accident Report (NTSB Form 6120.1/2) that he was returning to the airport after a quick maintenance flight. The Boulder City UNICOM airport advisory reported winds as 120 degrees, variable 10 to 15 knots with gusts, and landing on runway 9R. The pilot visually checked the windsock and noted it indicating southeasterly. He made an uneventful tail wheel landing on runway 9R. As the airplane's speed reached 45 knots during the landing roll, a strong gust of wind pushed the airplane to the right. Despite left rudder, left brake, and left aileron inputs, the airplane continued to veer to the right. The airplane veered off the right side of the runway and struck a runway distance remaining sign.
