Event Location
Probable Cause
The pilot's failure to maintain directional control during a landing rollout with a crosswind.
Full Narrative
According to the pilot of the tailwheel-equipped airplane, he landed on runway 28. During the rollout, the airplane became "erratic for no apparent reason," veered off the left side of the runway, encountered standing water in the grass and nosed over, damaging the vertical stabilizer. Runway 28 was 4,501-feet-long and 100-feet-wide. Winds, recorded at the airport 17 minutes after the accident, were from 360 degrees true at 12 knots. A postflight examination of the airplane revealed no preexisiting mechanical anomalies.
