Aircraft involved
Probable cause & findings
The pilot's improper landing flare, which resulted in a bounced landing and his subsequent failure to maintain directional control in a gusting, left quartering headwind.
Factual narrative
The pilot of the tailwheel equipped airplane reported that, during a left wing low (sideslip) landing and prior to touchdown, he leveled the wings, and the airplane bounced. He then increased the throttle slightly, adjusted the pitch to cushion the subsequent bounce but the airplane veered right, exited the runway to the right, and ground looped. The airplane sustained substantial damage to the left wing. 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 station located on the airport reported that 5 minutes after the accident, the wind was from 310° at 6 knots, gusting 12 knots. The airplane landed on runway 34.
