NTSB Narrative Summary Released at Completion of Accident

A CFI AND COMMERCIAL RATED PILOT WERE PRACTICING SIMULATED EMERGENCY LANDINGS WITH POWER RECOVERIES. THE STUDENT SET UP AN APPROACH TO A CULTIVATED FIELD AND WHEN POWER WAS ADDED, THE ENGINE ADVANCED TO 1300 RPM, THEN RETURNED TO IDLE. FURTHER ATTEMPTS TO INCREASE RPM WERE FUTILE. THE CFI TOOK THE CONTROLS, CLOSED THE THROTTLE AND PREPARED FOR THE LANDING. AT TOUCHDOWN THE NOSE WHEEL DUG INTO THE SOFT TERRAIN AND THE AIRPLANE NOSED OVER. A POST-ACCIDENT INSPECTION AND ENGINE RUN BY AN A&P MECHANIC WITH INSPECTION AUTHORIZATION FAILED TO REVEAL ANY EVIDENCE TO EXPLAIN THE REPORTED MALFUNCTION. THE AIRCRAFT WAS OPERATING IN THE CARBURETOR ICING PROBABILITY REGION.
