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 reported that during the landing roll, a right quartering tailwind pushed the tail to the left, the airplane exited the dirt strip to the right, where the lower right wing of the bi-plane struck an embankment. The airplane collided with a ditch and nosed over, sustaining substantial damage to both the upper and lower left wings. The pilot reported no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
