The pilot of the accident airplane made a straight-in approach to the 1,000 feet long airstrip. The pilot said he thought his ground speed felt a little fast, and that he thought he might have landed with a tailwind. He said the airplane touched down about halfway down the runway. He said when the main wheels touched he applied the brakes, the wheels locked-up, and the airplane nosed over. The airplane came to rest upside down near the center of the airstrip. A postaccident inspection by the pilot's mechanic disclosed no anomalies with the brakes.
