## Analysis

THE PILOT STATED THAT AS HE WAS RETURNING TO THE AIRPORT, THE ENGINE SPUTTERED ONCE AND THE RPM DROPPED VERY LOW. HE APPLIED CARB HEAT, BUT THERE WAS NO CHANGE, SO HE MADE AN EMERGENCY LANDING IN A CORN FIELD WHERE THE AIRCRAFT NOSED OVER. DURING AN OPERATIONAL CHECK AFTER THE ACCIDENT, NO MECHANICAL PROBLEMS WERE FOUND.
