The NTSB's narrative final · quoted from the NTSB record
THE FLIGHT INSTRUCTOR WAS GIVING INSTRUCTION TO THE PRIVATE PILOT IN TAKEOFF AND LANDINGS. SHORTLY AFTER THE FOURTH TAKEOFF, AT AN ESTIMATED ALTITUDE OF 800' AGL, THE ENGINE BACKFIRED AND LOST POWER. CARBURETOR HEAT WAS APPLIED AFTER THE POWER LOSS. A FORCED LANDING WAS MADE TO A ROUGH FIELD, AND THE AIRPLANE NOSED OVER DURING THE GROUND ROLL. AN INSPECTION AND RUN-UP OF THE ENGINE FAILED TO DISCLOSE ANY MECHANICAL ANOMALIES. PREVAILING METEOROLOGICAL CONDITIONS WERE CONDUCIVE TO THE FORMATION OF SERIOUS CARBURETOR ICING.
