NTSB Narrative Summary Released at Completion of Accident

The certificated commercial pilot was landing on runway 24 in a tailwheel equipped airplane on a paved runway. The pilot stated that just after touchdown, a sudden wind shift caused him to lose directional control, and the airplane ground looped to the right. During the ground loop the left main landing gear collapsed, and the left wing struck the ground. The airplane came to rest off the right side of the runway, and sustained substantial damage to the left wing and fuselage. Merrill Field wind conditions at the time of the accident were reported to be from 216 degrees (magnetic) at 8 knots.

NTSB Probable Cause Narrative

The pilot's inadvertent ground loop.
