The pilot departed on a local flight. He indicated that the winds were getting stronger and had shifted as he returned to the airport. He overflew the field, but the windsock still indicated that 26 was the preferred runway. He turned final at 80 knots with the landing gear and flaps down. The airplane bounced on touchdown, turned to the left side of the runway, and veered off the pavement into grass. As the airplane was slowing down through 15 knots, it encountered a drainage ditch, spun around, and ended up on its nose. The airplane sustained substantial damage to the wings, and the landing gear from one wing and the nose was sheared off. The pilot indicated that a slower approach speed might have prevented the accident. In his written report, the pilot stated that there were no mechanical malfunctions or failures.
