Analysis

The pilot was practicing takeoffs and landings in his homebuilt aircraft. Directional control of the aircraft was lost after it touched down during a landing. Subsequently, it swerved off the side of the runway, went in an area of tall grass & hit a ditch, which sheared off the landing gear.
