Aircraft involved
Probable cause & findings
The pilot’s failure to maintain directional control while landing in crosswind conditions.
Factual narrative
The pilot of the tailwheel-equipped airplane reported that, while landing in crosswind conditions, as the tailwheel set down the airplane veered left. Subsequently, the airplane exited the left side of the runway, struck a well head and came to rest nose down. The airplane sustained substantial damage to the fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The automated weather observation system about 7 nautical miles from the accident site reported, about the time of the accident, the wind was 280° at 11 knots. The pilot landed on runway 26.
