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

While performing a series of touch-and-go landings, the pilot inadvertently allowed the tail wheel-equipped airplane to touch down with one wing lower than the other. Almost immediately after the airplane touched the surface, it suddenly veered toward the edge of the runway. The pilot added power in an attempt to execute a go-around, but before he could get the airplane airborne, it departed the runway surface and impacted the adjacent terrain.

Factual narrative

While performing a series of touch-and-go landings, the pilot inadvertently allowed the tail wheel-equipped airplane to touch down with one wing lower than the other. Almost immediately after the airplane touched the surface, it suddenly veered toward the edge of the runway. The pilot therefore added power in an attempt to execute a go-around, but before he could get the airplane airborne, it departed the runway and impacted the adjacent terrain.
