Probable cause

The pilot's improper rudder application during landing on a dirt airstrip, which resulted in a loss of directional control, runway excursion, and subsequent nose-over

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot of the tailwheel-equipped airplane reported that, while landing on a private, dirt airstrip, he lost sight of the airstrip, and the airplane veered left. Concerned the airplane would ground loop, he applied minimal right rudder. He then chose to abort the landing and applied full power. As the airplane was about to become airborne, it exited the runway to the left, and the main landing gear encountered water. The pilot reduced the engine power to idle, and the airplane nosed over. The airplane sustained substantial damage to the left wing lift strut. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
