NTSB Narrative Summary Released at Completion of Accident

WHILE FLYING IN CONDITIONS WHERE CARBURETOR ICING COULD BE EXPECTED AT BOTH GLIDE AND CRUISE POWER, THE PILOT FAILED TO APPLY CARBURETOR HEAT TO CHECK FOR ICE ACCUMULATION IN THE CARBURETOR THROAT. THE ENGINE EVENTUALLY LOST POWER DUE TO CARBURETOR ICING, AND THE PILOT ATTEMPTED A FORCED LANDING IN A NEARBY FIELD. DURING THE LANDING ROLL IN THE ROUGH/UNEVEN TERRAIN, THE LANDING GEAR COLLAPSED.

NTSB Probable Cause Narrative

THE PILOT DELAYED USING CARBURETOR HEAT UNTIL THE ENGINE HAD ALREADY LOST POWER DUE TO ICE FORMING IN THE CARBURETOR THROAT. FACTORS INCLUDE CARBURETOR ICING CONDITIONS, AND ROUGH/UNEVEN TERRAIN IN THE FIELD WHERE THE FORCED LANDING WAS MADE.
