Accident Summary:
UH-1H AIRCRAFT NUMBER 66-16112 WAS ASSIGNED AS LEAD AIRCRAFT OF 8 TROOP CARRYING AIRCRAFT ON COMBAT ASSAULT MISSIONS ON 23 JANUARY 1970. AFTER COMPLETING THE LIFTS, THE FIRST THREE AIRCRAFT WERE ASSIGNED MEDICAL EVACUATION MISSIONS UNDER THE CONTROL OF THE COMMAND AND CONTROL AIRCRAFT WITH AIRCRAFT 112 AS LEAD AIRCRAFT. DURING THE ENTIRE MORNING THE AIRCRAFT HAD GIVEN NO INDICATIONS OF MECHANICAL DEFICIENCIES, WAS PERFORMING ROUTINELY, AND HAD HAD NO RECENT MAINTENANCE ON ANY CRITICAL COMPONENT(S). THE AIRCRAFT ARRIVED AT THE MEDEVAC SITE AT APPROXIMATELY 1010 HOURS WITH 1000 LBS OF FUEL, ONLY THE CREW AND THEIR COMBAT GEAR ON BAORD, AND CARGO DOORS SECURED IN THE OPEN POSITION. THE SELECTED AREA WAS AN OPEN FIELD APPROXIMATELY 100' X 50' (ESTIMATED) WITH PORTIONS DEVOTED TO SUGAR CANE CROPS, BORDERED BY TREES AND TREELIKE VEGETATION ON ALL SIDES. THE LONG AXIS RAN GENERALLY NORTHEAST TO SOUTHWEST WITH A COCONUT GROVE TO THE NORTH WEST AS THE HIGHEST AND MOST PROMINENT OBSTRUCTION (REFERENCE DIAGRAM). THE GROUND ADVISOR, CONSIDERING WIND, AREA CONFINEMENT AND ENEMY SITUATION RECOMMENDED AN APPROACH FROM THE SOUTHEAST TO THE NORTHWEST. THIS WOULD HAVE PROVIDED FOR A NORMAL APPROACH AND MINIMUM TIME IN LANDING ZONE AS IT WAS IN LINE FOR THE WOUNDED PICK-UP ELIMINATING TURNS AND UNNECESSARY HOVERING. THE AIRCRAFT COMMANDER MADE HIS APPROACH FROM THE NORTHWEST TO THE SOUTHEAST. IT WAS NORMAL TO STEEP IN ORDER TO CLEAR THE HIGH COCONUT TREES, ESTIMATING A CROSS WIND FROM THE LEFT OF ABOUT 5 KNOTS AND ALL INSTRUMENTS WERE IN THE GREEN. IN ORDER TO STAY CLEAR OF THE OTHER SURROUNDING VEGETATION, THE APPROACH TERMINATED AT A 10-15 FOOT HOVER AND A LEFT PEDAL TURN WAS IMMEDIATELY INITIATED. AT THIS POINT A LOSS OF POWER WAS FELT AND THE ENGINE RPM DECLINED RAPIDLY TO AN ESTIMATED 6000-RPM. IN AN ATTEMPT TO REGAIN THE LOST RPM THE COLLECTIVE WAS LOWERED BUT WITH NO RESULTS. AT APPROXIMATELY 5 OR 6 FEET ABOVE THE GROUND, COLLECTIVE WAS PULLED IN TO CUSHION THE LANDING. THE AIR CRAFT COMMANDER WHO WAS AT THE CONTROLS REPORTED THAT THIS MANEUVER SEEMED TO HAVE NO EFFECT AND THAT THE AIRCRAFT TOUCHED DOWN LEVEL WITH NO FORWARD OR LATERAL MOTION INTO AN EXTREMELY SOFT MARSHY, MUDDY AREA. THE AIRCRAFT THEN ROCKED FORWARD AND WHEN FULL AFT CYCLIC HAD NEGATIVE RESULTS, RIGHT CYCLIC WAS APPLIED. THE MAIN ROTOR STRUCK THE GROUND TO THE RIGHT FRONT, CAUSING THE THE RANSMISSION TO RIP LOOSE AND COME TO REST TO THE RIGHT SIDE OF THE AIRCRAFT. THE RESULTING FORCE WHICH PULLED THE TRANSMISSION OUT ASSISTED WHATEVER LIFT REMAINED IN THE ROTOR PRIOR TO STRIKING THE GROUND TO ROLL THE AIRCRAFT ONTO ITS RIGHT SIDE. ON THE INITIAL IMPACT THE GUNNER STARTED TO UNFASTEN HIS SEAT BELT AND APPEARED SUCCESSFUL AS WHEN THE AIRCRAFT LURCHED FORWARD HE WAS THROWN FORWARD LANDING FACE DOWN IN THE MUD. THE AIRCRAFT CAME TO REST ATOP 3/4 OF HIS BODY,FROM THE SHOULDERS DOWN, HIS HELMET STILL ON. ALL OTHER CREW MEMBERS RECEIVED NO INJURIES AS A RESULT OF BEING STRAPPED IN SECURELY AND THEIR HELMETS BEING SECURELY FASTENED. OBSERVERS OUTSIDE THE AIRCRAFT STATED THE AIRCRAFT SEEMED TO FALL TO THE GROUND IMPACTING SLIGHTLY TAIL LOW, AND THAT IT APPEARED TO COME UP AGAING PRIOR TO THE MAIN ROTOR STRIKING THE GROUND. THE AIRCRAFT COMMANDER AND PILOT SWITCHED THE MAIN FUEL AND BATTERY TO OFF, BUT COULD NOT ROLL OFF THE THROTTLE PAST THE FLIGHT IDLE DETENT, EVEN PRIOR TO TURNING THE BATTERY OFF. THE ENGINE CONTINUED TO RUN UNTIL FUEL REMAINING IN THE ENGINE WAS FINALLY EXHAUSTED. THE CREWCHIEF EXITED THROUGH THE LEFT CARGO DOOR OPENING WHILE THE OTHERS CAME OUT THROUGH THE GREEN HOUSE. THEY AND SEVERAL OTHERS ON THE GROUND OIFTED THE AIRCRAFT ENOUGH TO EXTRICATE SPECIALIST KENNON, THE GUNNER. NO FIRE OR FURTHER INJURIES RESULTED. THE SECOND AIRCRAFT OF THE THREE ASSIGNED TO THE MISSION LANDED TO TAKE THE INJURED GUNNER TO BINH THUY.\\
