The grass surface was wet and uneven. The helicopter's right skid caught in the sod during the landing ground run, and the helicopter rolled onto it's right side. Both pilot's attempted to prevent the rollover by applying full left cyclic without success. There was a left 5-knot crosswind reported by the air traffic control tower at the time.
