Analysis

The pilot attempted a crosswind landing at the end of a pleasure cross country flight. A loss of directional control occurred on short final and the aircraft drifted right of the runway. A go-around was attempted without success and the aircraft rolled off the right side of the runway where it contacted a ditch and nosed over.
