THE CFI PLANNED TO DEMONSTRATE TO HIS STUDENT HOW TO EXECUTE AN EMERGENCY LANDING. THE CFI CLOSED THE THROTTLE AND DESCENDED TO LESS THAN 50 FEET ABOVE GROUND LEVEL BEFORE HE ATTEMPTED TO ADD ENGINE POWER IN TERMINATION OF THE DEMONSTRATION. AS THE ENGINE POWER WAS BEING RESTORED, THE AIRPLANE DESCENDED A FEW FEET, CONTACTED THE GROUND AND NOSED OVER. GUSTY SURFACE WINDS EXISTED. THE CFI REPORTED THAT HE HAD NOT MAINTAINED A 'SUFFICIENT BUFFER ZONE OF SAFETY' DURING DEMONSTRATION.
Probable Cause: THE CFI'S FAILURE TO INITIATE THE GO-AROUND MANEUVER IN A TIMELY MANNER, AND HIS FAILURE TO TERMINATE THE SIMULATED EMERGENCY MANEUVER AT A PROPER ALTITUDE. A CONTRIBUTING FACTOR WAS THE GUSTY SURFACE WIND.
