Accident Summary:

 ON 1 APRIL 1969, ^WO1 GARY R. BRYDGES^, WAS THE AIRCRAFT COMMANDER OF AN AH-1G HELICOPTER, ^67-15620^. THE CO-PILOT, ^WO1 ROBERT T. PILLION^, WAS NOT QUALIFIED IN THE AH-1G HELICOPTER. DURING THE PREFLIGHT NO MECHANICAL DEFICIENCIES WERE NOTED ON THE AIRCRAFT. AT 0730, ^WO1 BRYDGES^ TOOK OFF FROM PHAN THIET ENROUTE TO PHAN RANG TO REFUEL AND THEN PROCEED TO THE AREA OF OPERATIONS. WHILE IN THE AREA OF OPERATION, ^WO1 BRYDGES^ FLEW THE HELICOPTER IN A LEFT ORBIT OF 60-80 KNOTS. AFTER APPROXIMATELY ONE HOUR THE AIRCRAFT COMMANDER BEGAN RECEIVING EXTREME FORE AND AFT FEEDBACK THROUGH THE CYCLIC CONTROL DURING LEVEL FLIGHT. THE FEEDBACK WAS INTENSE ENOUGH TO REQUIRE THE AIRCRAFT COMMANDER TO USE BOTH HANDS WHILE ATTEMPTING TO CONTROL THE CYCLIC. THE CO-PILOT WAS ORDERED TO CONTROL THE COLLECTIVE. THERE WERE NO CAUTION LIGHTS OR ABNORMAL INDICATIONS ON THE AIRCRAFT'S INSTRUMENT PANEL. THE NOSE OF THE AIRCRAFT BEGAN TO PITCH UP AND THE AIRSPEED BEGAN TO DECREASE. DESCENT WAS ESTABLISHED WITH A NORMAL APPROACH ANGLE. AS AIRSPEED DECREASED, CYCLIC FEEDBACK INCREASED. POWER WAS INCREASED TO SLOW THE DESCENT AND THE AIRCRAFT TERMINATED DESCENT AT APPROXIMATELY TEN (10) FEET OF ALTITUDE. THE GROUND CUSHION WAS LOST DUE TO CYCLIC MOVEMENT AND THE AIRCRAFT BEGAN TO SETTLE TO THE GROUND. AS THE AIRCRAFT IMPACTED, THE MAIN ROTOR BLADES FLEXED DOWN INTO THE 42 DEGREE BOX AREA WHICH CAUSED THE TAIL ROTOR DRIVE SHAFT, WHICH CONNECTS THE GEARBOXES TOGETHER AND THE 90 DEGREE GEARBOX TO SEPARATE FROM THE AIRCRAFT. THIS RESULTED IN DAMAGE TO THE SKIDS, TAIL BOOM, SINK ELEVATORS, ENGINE, TRANSMISSIONS, TAIL ROTOR DRIVE SHAFT, 42 DEGREE GEARBOX, 90 DEGREE GEARBOX, TAIL ROTOR BLADES AND MAIN ROTOR BLADES. THE HELICOPTER WAS SLUNG LOAD TO THE B TROOP MAINTENANCE AREA. INSPECTION REVEALED THAT MECHANICAL FAILURE OF THE NUT ASSEMBLY, HYDRAULIC, PART #209-076-021-3, WAS FORCED OUT OF THE BEARING HOUSING, FSN 1680-872-1144. THIS CAUSED THE CYLINDER ASSEMBLY TO MOVE UP, FORCING THE CYCLIC INTO THE AFT POSITION. THE BUSHING SET WOULD NOT SEAT ITSELF BACK INTO THE BEARING HOUSING, KEEPING THE CYLINDER ASSEMBLY FULLY EXTENDED IN THE AFT POSITION.\\
