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 stated that during the landing roll the airplane began to drift to the left. The pilot applied right rudder and right aileron, and the airplane then encountered a gust of wind from the right. The left wing then struck the runway surface and the airplane departed the runway to the right, coming to rest in soft soil. The airplane sustained substantial damage to the lower wing spar during the accident sequence. The pilot reported that the airplane and engine had no mechanical failures or malfunctions prior to the accident.
