## Analysis

AFTER LANDING IN A PRACTICE AREA THE INSTRUCTOR TOLD THE STUDENT TO PICK THE HELICOPTER UP TO A HOVER. THE AIRCRAFT LIFTED OFF THE GROUND TO APPROXIMATELY 5 FEET AND YAWED TO THE RIGHT 45 DEGREES. AS THE INSTRUCTOR APPLIED LEFT PEDAL AND LOWERED COLLECTIVE THE STUDENT APPLIED LEFT CYCLIC. BEFORE THE INSTRUCTOR COULD APPLY CORRECTIVE ACTION THE HELICOPTER'S LEFT SKID STRUCK THE GROUND AND THE AIRCRAFT ROLLED OVER.
