On April 27, 2005, about 1300 mountain daylight time, a Cessna 150L, N1387Q, registered to and flown by the pilot as a 14 CFR Part 91 personal flight, collided with a taxiway sign during landing at Eureka Airport, Eureka, Montana. Visual meteorological conditions prevailed at the time, and no flight plan was filed. The aircraft was substantially damaged and the private pilot and his pilot-rated passenger were not injured. The flight originated from Eureka at 1200 as a local flight. During a telephone interview, the pilot reported that during the landing roll on runway 36, the aircraft encountered a gust of wind. The pilot was unable to maintain directional control, and the aircraft traveled to the side of the runway where the horizontal stabilizer collided with a taxiway sign. The taxiway sign was knocked over and the horizontal stabilizer sustained substantial damage. The pilot reported no mechanical failures or malfunctions with the aircraft at the time. The pilot reported the winds to be from 080 degrees at 10 knots with gusts to 15 knots.
