THE INSTRUCTOR PILOT SIMULATED AN ENGINE OUT EMERGENCY APPROACH. THE INSTRUCTOR AND STUDENT REALIZED THAT THEY WERE NOT GOING TO REACH THE RUNWAY DURING THE GLIDE. THE STUDENT APPLIED POWER AND THE ENGINE DID NOT RESPOND. THE INSTRUCTOR TOOK CONTROL AND COMPLETED A FORCED LANDING IN WHICH THE NOSE GEAR SHEARED OFF ON TOUCHDOWN AND THE AIRPLANE NOSED OVER. SUBSEQUENT ENGINE TESTS SHOWED NO MECHANICAL OR NON-MECHANICAL REASON FOR THE LOSS OF POWER.
