What reportedly happened: The pilot said the landing was normal, but during the rollout the wind shifted and gusted up to 17 knots.
As he turned the airplane off the runway, he did not increase engine power or use the brakes to maintain control, and the airplane ground looped.
Probable cause: The pilot’s inadequate compensation for the wind conditions and loss of directional control while taxiing off the runway.
