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, while on the downwind leg, "the tower told us that there was a crosswind." During the landing roll, the airplane veered left and exited the runway, and the right wing struck the ground. When the airplane came to rest, the pilot exited the airplane and determined that there was no wind. The airplane sustained substantial damage to the right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

Factual narrative

The pilot in the tailwheel-equipped airplane reported that, on the downwind for runway 25R, "the tower told us that there was a crosswind." During the landing roll, the airplane veered to the left and exited the left side of the runway, and the right wing collided with the ground. When the airplane came to rest, the pilot exited the airplane and determined that there was "no wind." The METAR at the accident site reported that, about the time of the accident, the wind was from 25° at 08kts. The airplane sustained substantial damage to the right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
