Narrative:THE ACFT CRASHED WHILE ATTEMPTNG A TAKEOFF FROM A GRAVEL BAR. THE PLT ESTIMATED THE USEABLE AREA FOR TAKEOFF AS 400 TO 500 FT. INVESTIGATION REVEALED THAT THE DENSITY ALTITUDE WAS AT LEAST 3400 FT MSL. A TEST ENG RUN AFTER THE ACFT WAS RECOVERED, DETERMINED THAT THE CARBURETOR HEAT 'BUTTERFLY' VALVE FUNCTIONED NORMALLY IN THE 'ON' POSITION BUT WHEN PLACED IN THE 'OFF' POSITION WOULD ONLY OPEN PARTIALLY. THIS PREVENTED THE ENG FROM DELIVERYING FULL STATIC POWER DURING THE TEST.
