## Analysis

THE AIRCRAFT WAS ON APPROACH FOR LANDING AT HAMILTON, NEW YORK WHEN THE CROSS POWER LEVERS WERE PULLED BACK TO FLIGHT IDLE. THE LEFT PROP WENT INTO BETA MODE STALLING THE LEFT WING AT ABOUT 8 FEET ABOVE THE RUNWAY. THE AIRCRAFT ROLLED ABOUT 20 DEGREES TO THE LEFT, THEN FELL TO THE RUNWAY. AN INSPECTION VERIFIED THE POSIBILITY OF THE LEVER GOING BEYOND THE STOP. THE POWER LEVER INCORPORATES A SPRING LOADED GUARD WHICH ENGAGES A GATE ON THE QUARDRANT AT THE FLIGHT IDLE POSITION TO PREVENT MOVEMENT OF THE LEVER INTO GROUND OPERATING RANGE WHILE IN FLIGHT.
