The airplane was substantially damaged after impacting a ditch and nosing over during landing. The pilot reported landing with extra airspeed to compensate for variable wind conditions. He reported that the winds at a nearby airport were from 310-330 degrees, at 10 knots gusting to 15 knots. He reported landing on runway 06 (2400 feet by 100 feet), which is oriented downhill, and upon landing he retracted the flaps and actuated the brakes by pulling the lever, but the airplane did not slow down enough to stop. He stated that when he realized he was not slow enough, it was too late to apply power for a go-around, so he "rode it out." The airplane crossed the road off the departure end of the runway, struck a ditch, and nosed over in a farm field. The pilot was not injured. The airplane damage included the propeller, engine, engine mount, cowling, two wing struts, windshield, rudder, one elevator, wing ribs and fabric. The pilot did not report any mechanical malfunctions or failures with the airplane.
