The pilot stated that he made a normal takeoff, climbed above the trees, and began an approach to landing for the turf runway. The pilot made a "normal landing, and in an instant, the nose started down." The airplane's propeller struck the ground, and the airplane nosed over, coming to rest inverted. Postaccident inspection by a Federal Aviation Administration inspector revealed that the airplane exhibited no mechanical malfunctions or anomalies. The nearest weather reporting station, located approximately 9 nautical miles south of the accident site, reported winds from 060 degrees at 5 knots around the time of the accident. Several attempts were made to obtain the NTSB Pilot/Operator Report from the pilot and operator; however, neither submitted the form. ## Factual narrative The pilot of the tailwheel airplane departed an asphalt runway with the intention of moving the airplane to an adjacent turf runway at the same airport.
