The pilot's failure to maintain directional control during the landing roll.

Analysis

The pilot stated '...during the rollout with the tailwheel on the ground the aircraft became uncontrollable and turned to the right.' The aircraft turned about 270 degrees before it came to a stop. The left main landing gear collapsed during the turn. The pilot landed on runway 13. The winds were reported to be out of 340 degrees at 7 to 8 knots. There was no evidence of pre-existing mechanical anomaly.
