Analysis

The CFI reported that during the landing roll on runway 24, at fla-bob airport, Riverside, CA, the airplane began to 'drift to the right.' The CFI applied left rudder to correct the excursion but his left foot slipped off the rudder bar and became lodged against the bar and floor. The airplane continued the right turn and the left wing contacted the ground. The surface winds were from the right of the nose abt 20 deg at about 7 knots. The effective crosswind component was less than 3 knots. The CFI did not report any airplane mechanical malfunctions and/or failures.
