Accident Summary:
^MR. CLINE^, THE AIRCRAFT COMMANDER, FLEW THE FIRST SORTIE INTO THE LZ. HE WAS THE NUMBER TWO MAN IN A FLIGHT OF TWO AND HAD NO DIFFICULTIES LANDING. THE FORMATION WAS ECHELON RIGHT WITH THE LEAD AIRCRAFT LANDING IN THE UPPER LEFT CORNER OF THE LZ. ^MR. CLINE^ LANDED HIS AIRCRAFT BETWEEN THE TWO BOMB CRATERS. THE LANDING ZONE WAS ADEQUATE FOR TWO AIRCRAFT, BUT THERE WERE SMALL TREES FOUR TO SIX FEET TALL THROUGHOUT THE AREA AND ALONG THE APPROACH ROUTE. AFTER UNLOADING THE TROOPS IN THE LZ, ^MR. CLINE^ THEN FLEW THE AIRCRAFT BACK TO THE PZ AT ^CAMP EVANS^. ONCE THERE HE GAVE CONTROL OF THE AIRCRAFT TO ^LT. MUELLER^ FOR THE SECOND SORTIE INTO THE SAME LZ. THE SECOND LOAD CONSISTED OF FOUR PASSENGERS FROM THE ^1-506 INFANTRY AND ONE ARVN SOLDIER^. THE FLIGHT FROM THE PZ TO THE LZ WAS UNEVENTFUL. UPON TURNING TO THE LANDING HEADING OF 290 DEG AND WITH HIS TOUCHDOWN POINT IN SIGHT, ^LT. MUELLER^ WAS CLEARED TO LAND BY BOTH THE CREWCHIEF AND GUNNER. HE WAS TOLD TO KEEP HIS TAIL HIGH ON SHORT FINAL BECAUSE OF SMALL TREES BENEATH HIM. ^LT. MUELLER^ WAS ABOUT TO HOVER FORWARD AT A HEIGHT OF TWO FEET WHEN THE TROOPS STARTED TO EXIT FROM BOTH SIDES OF THE AIRCRAFT WITHOUT A COMMAND FROM THE CREW. THE RESULT OF THIS MASS EXODUS CAUSED THE CENTER OF GRAVITY OF THE AIRCRAFT TO SHIFT REARWARD WITH THE TAIL DROPPING DOWN AND TO THE LEFT. THE TAIL ROTOR MADE CONTACT WITH ONE OF THE SMALL TREES RESULTING IN THE 90 DEG GEAR BOX BEING TORN FROM ITS MOUNT AND CAUSING A LOSS OF DIRECTIONAL CONTROL. THIS LOSS OF DIRECTIONAL CONTROL CAUSED THE AIRCRAFT TO START SPINNING TO THE RIGHT. AS THE SPIN STARTED ^LT. MUELLER^ PULLED UP ON THE COLLECTIVE PITCH LEVER CAUSING THE AIRCRAFT TO CLIMB TO A HEIGHT OF TEN FEET. ^MR. CLINE^ IMMEDIATELY TOOK OVER CONTROL OF THE AIRCRAFT, LOWERED THE COLLECTIVE AND EXECUTED A HOVERING AUTOROTATION. THE AIRCRAFT SETTLED TO THE GROUND AFTER COMPLETING ONE AND ONE HALF REVOLUTIONS. IT LANDED HARD ON THE AFT LEFT SIDE CAUSING EXTENSIVE DAMAGE TO THE SKIDS AND FUSELAGE, BUT STAYED UPRIGHT. THE TAIL BOOM HIT THE GROUND WHEN THE AIRCRAFT TOUCHED DOWN ALMOST TEARING ITSELF FROM THE AIRCRAFT. ^MR. CLINE^ AND ^LT MUELLER^ IMMEDIATELY SHUT DOWN THE AIRCRAFT. UPON EXITING THEY STRIPPED IT OF ITS RADIOS AND GUNS, THEN SECURED THE MAIN ROTOR BLADE AND WAITED TO BE EXTRACTED FROM THE AREA.\\
