Probable cause

The pilot's failure to maintain directional control during the landing rollout and the resulting ground loop. A contributing factor was the excessive tail wheel steering (rudder) input by the pilot.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

The airplane was substantially damaged when the pilot lost directional control during the landing rollout. The airplane subsequently ground looped causing the left wing to contact the ground and the left main landing gear to collapse. The pilot reported that he flew a "normal downwind to final" with a "very good touchdown followed by the start of a smooth rollout." He stated that the tail wheel began to "wobble (chatter)" and the airplane drifted to the left side of the runway. He added engine power as the airplane reached the edge of the runway and applied rudder correction to return to the runway centerline. The pilot stated, "Too much right rudder started the ground loop which finished with the airplane having turned 180 [degrees]." When the airplane came to rest, the "left wing was down in the dirt with the left main folded under the airplane," according to the pilot. He noted no malfunctions with the airplane. He also commented that more patience with the tail wheel "chatter" may have prevented the over controlling which led to the ground loop.
