DURING FACTORY FLT TRAINING, PRIOR TO DELIVERY OF THE NEW HELICOPTER TO THE OWNER, THE CFI SAID HE ASKED THE STUDENT TO PERFORM A SERIES OF EMERGENCY PROCEDURES WHICH INCLUDED QUICK STOPS FROM AN INITIAL TAKEOFF FOLLOWED BY HOVERING AUTOROTATIONS. THE CFI SAID THE STUDENT SUCCESSFULLY COMPLETED ONE SERIES OF MANEUVERS AND HE ASKED HIM TO DO ONE MORE. THE CFI SAID THAT DURING THE DECELERATION PHASE OF THE QUICK STOP, THE STUDENT MISTAKENLY 'ROLLED THE THROTTLE TO THE IDLE POSITION' AT ABOUT 25 FT AGL.
