Probable cause

Failure of the pilot to maintain directional control, which resulted in an inadvertent ground swerve and collision with tall grass beside the runway. The tall grass was a related factor.

Sequence of events

Analysis

The pilot stated that as the tailwheel settled during the landing, the aircraft began to veer to the right. A go-around was initiated and the aircraft became airborne. However, the aircraft went off the right side of the runway and contacted tall grass, which caused the spade under the left bottom wing to separate. The aircraft then rolled to the left and the left wing tip contacted the ground. The aircraft touched down and the main landing gear separated. The aircraft then rotated to the left and came to rest. A post-crash examination of the aircraft revealed no evidence to indicate a precrash failure or malfunction of the landing gear or brake systems.
