On August 21, 1994, at 0905 Pacific daylight time, a homebuilt Allen D. Potts Wag-A-Bond, N47AT, nosed over during the landing roll on an open field after the engine experienced a loss of power, five miles south of Benton City, Washington.

The pilot reported that during the descent for landing to Kennewick, Washington, the engine experienced a loss of power. The airplane was unable to make it to the airport and the pilot elected to initiate a forced landing, to the south, on a dirt road. During the approach, a strong wind from the west was present. The pilot was unable to remain aligned with the road and the airplane touched down in a plowed field next to the road. During the landing roll in soft dirt, the airplane nosed over. The pilot reported that there were no mechanical failures or malfunctions with the engine, however, during a telephone interview the pilot stated that he suspected fuel starvation that resulted in the loss of engine power.
