## Analysis

PLT STATED THAT ON LANDING ROLL AT APPROXIMATELY 30 TO 35 KNOTS THE NOSE LANDING GEAR BEGAN TO SHIMMY AND TURN TO THE LEFT. FULL RIGHT BRAKE AND RUDDER COULD NOT CORRECT THE LEFT TURNING TENDENCY OF THE AIRCRAFT. THE AIRCRAFT RAN OFF THE LEFT SIDE OF THE RUNWAY INTO SAND AND THE NOSE LANDING GEAR SEPARATED AND THE MAIN LANDING GEARS COLLAPSED. POST ACCIDENT INSPECTION OF THE NOSE LANDING GEAR REVEALED NO EVIDENCE TO INDICATE THE CAUSE OF THE SHIMMY AND LEFT TURNING TENDENCY.
