Narrative:
THE STUDENT PILOT WAS PRACTICING SIMULATED ENGINE FAILURE FORCED LANDINGS WITH HIS INSTRUCTOR. DURING ONE OF THE APPROACHES, THE STUDENT INADVERTENTLY PULLED OUT THE MIXTURE CONTROL HANDLE TOO FAR AND THE ENGINE QUIT. ATTEMPTS TO RESTART THE ENGINE BY THE INSTRUCTOR WERE UNSUCCESSFUL. THE INSTRUCTOR LANDED THE AIRCRAFT IN A MUDDY FIELD AND IT NOSED OVER. THE AIRCRAFT WAS RECOVERED AND EXAMINED. AFTER THE EXAMINATION, THE ENGINE WAS STARTED AND IT OPERATED NORMALLY. THERE WERE NO MECHANICAL PROBLEMS FOUND DURING THE EXAMINATION OR THE ENGINE RUN.

Probable Cause: The improper supervision of the student pilot by the instructor by allowing the student to inadvertently pull the mixture control handle too far out causing the engine to lose power. The wet terrain condition was a factor.
