The airplane ground looped during the landing roll. After practicing touch-and-go's at another airport, the pilot returned for landing. The touchdown was normal except for a "slight bounce." During the roll out, the left wing lifted and the airplane turned slightly to the left. The pilot applied "rudder correction with [the] stick full back." The airplane continued to turn left and he attempted differential braking; however, the airplane continued to turn left. The airplane came to rest facing about 90 degrees left of the runway heading. The right wing sustained a broken spar and broken ribs, and the right landing gear was bent during the turn. In a post accident examination, all flight controls functioned properly and no preimpact anomalies were found. The winds reported at 0953 were 240 degree at 6 knots. The winds reported at 1053 were 230 degrees at 7 knots.
Probable Cause: The pilot's inadequate compensation for crosswind conditions, which resulted in a loss of directional control and a ground loop.
