NTSB Narrative Summary Released at Completion of Accident

WITNESSES LOCATED 1/4 MI NORTH OF THE ACCIDENT SITE, OBSERVED THE GYROCOPTER DEPARTING THE DAVENPORT, IA AIRPORT AND TURNING TO THE SOUTHWEST. WHILE IN CRUISE FLIGHT THE WITNESSES OBSERVED THE AIRCRAFT MOVING IN AN UP AND DOWN MOTION PRIOR TO WHAT APPEARED TO BE PARTS OF THE GYROCOPTER FLYING OFF. THE GYROCOPTER THEN FELL VERTICALLY INTO A CORNFIELD. ON SCENE INVESTIGATION REVEALED THAT THE RUDDER WAS STRUCK BY THE MAIN ROTOR BLADE WHICH SEPARATED FROM ITS MOUNTING. A NEARBY WEATHER REPORTING STATION REPORTED A WIND CHANGE OF NEARLY 80 DEGREES AND WIND GUSTS TO 26 KNOTS DURING THE FLIGHT. LOCAL OPERATORS OF THE SAME TYPE OF GYROCOPTER INDICATED THE 'FLIGHT CONTROLS WERE EXTREMELY SENSITIVE INFLIGHT AND OVERCONTROL IS POSSIBLE WHEN IN TURBULENT WIND CONDITIONS.' NO PREIMPACT MECHANICAL MALFUNCTIONS/FAILURES WERE FOUND.
