Accident Summary:

 ON THE ^16TH OF DECEMBER 1968, 1LT PHILLIP J. AHNEMAN AND WO1 DAVID C. SWANSON^ WERE FLYING IN AIRCRAFT ^#66-16153^ OF THE ^189TH AHC^. THEY WERE FLYING A MISSION FOR THE ^5TH SPECIAL FORCES^ WORKING OUT OF ^KONTUM^. AT ABOUT ^1300 HOURS^ THEY PICKED UP SIX PASSENGERS AT ^KONTUM^ AND HEADED FOR A ^SPECIAL FORCES CAMP NORTHWEST OF DAK TO^. THEY WERE ADVISED BY THE TOWER TO LAND SHORT AND WAIT UNTIL A REFUELING POINT WAS OPEN. AFTER THE REFUELING AREA WAS CLEAR, ^1LT AHNEMAN^ PICKED THE SHIP UP TO A HOVER AND MOVED OVER ONE OF THE REFUELING PADS AND STARTED TO SIT DOWN. AT APPROXIMATELY ONE FOOT OFF THE GOUND, THE SHIP STARTED A SLOW TURN TO THE RIGHT. ^1LT AHNEMAN^ IMMEDIATELY APPLIED LEFT PEDAL TO STOP THE TURN. WITH FULL LEFT PEDAL IN THE SHIP STOPPED MOMENTARILY AND THEN STARTED SPINNING VIOLENTLY TO THE RIGHT. ^1LT AHNEMAN^ THEN REALIZED THAT HE HAD A TAIL ROTOR FAILURE OF SOME SORT AND STARTED TO ROLL THE THROTTLE OFF TO EXECUTE A HOVERING AUTOROTATION. PHOTOGRAPH #1 SHOWS THAT THE TAIL ROTOR BLADES WERE NOT DAMAGED ON IMPACT AND PROBABLY WERE NOT TURNING WHEN THE SHIP FINALLY CAME TO REST. THE THROTTLE WAS HARD TO TURN AND BEFORE ^1LT AHNEMAN^ COULD ROLL THE THROTTLE COMPLETELY OFF, THE SHIP HIT THE GROUND STILL SPINNING TO THE RIGHT. IT IS KNOWN THAT THE THROTTLE HAD BEEN WRITTEN UP ON A PREVIOUS FLIGHT FOR STICKING AND BEING HARD TO TURN. THE MAINTENANCE CREW OF THE ^604TH TRANS. DET.^ CHECKED THE THROTTLE AND SIGNED IT OFF AS BEING WITHIN LIMITS. THE 2408-13 SHOWING THIS WRITE UP COULD NOT BE FOUND EITHER AT THE ^540TH TRANS. DET^ IN ^QUI NHON^ WHERE THE AIRCRAFT WAS EVACUATED OR AT THE ^604TH TRANS DET.^ THE THROTTLE WAS CHECKED AFTER THE ACCIDENT AND FOUND TO TURN HARDER THAN NORMAL, BUT WELL WITHIN LIMITS. THE PILOT HAD STARTED TO HELP ROLL THE THROTTLE OFF, BUT BEFORE HE COULD REACH IT THE SHIP HAD HIT THE GROUND. HE THEN BRACED FOR THE CRASH. AFTER THE SHIP HAD HIT THE FIRST TIME, IT BOUNCED INTO THE AIR AGAIN STILL SPINNING, TO THE RIGHT. ^1LT AHNEMAN^ HAD HELD THE PITCH WHERE IT WAS AND AT THIS TIME DECIDED TO BOTTOM THE PITCH IN ORDER TO GET THE AIRCRAFT ON THE GROUND. THE AIRCRAFT HIT HARD JUST TO THE RIGHT OF THE REFUELING PAD. THE LEFT SKID HIT LEVEL BUT THE RIGHT SKID HIT ON SOME SAND BAGS THAT WERE COVERING A REFUELING HOSE. ON IMPACT, THE RIGHT SKID BROKE AND CAUSED THE UNDERSIDE OF THE AIRCRAFT TO COME IN CONTACT WITH THE GROUND. PHOTOGRAPH #2 SHOWS THE IMPACT OF THE SKIDS AND THE ARROW POINTS TO WHERE A PIECE OF RELIEF VALVE THAT BROKE OFF ON IMPACT WAS FOUND. WHEN THE RIGHT SKID BROKE IT CAUSED THE AIRCRAFT TO FLIP OVER AND HIT ON ITS LEFT SIDE. PHOTOGRAPH #3 SHOWS THE POINT OF IMPACT WHERE RIVETS FROM THE LEFT SIDE WERE FOUND AND THE ARROW POINTS TO A PIECE OF SAND BAG THAT WAS PICKED UP ON IMPACT. WHEN THE AIRCRAFT HIT ON ITS SIDES, THE ROTOR BLADES CAME IN CONTACT WITH THE GROUND. PHOTOGRAPH #4 SHOWS WHERE THE ROTOR BLADES CAME IN CONTACT WITH THE GROUND CAUSING THE AIRCRAFT TO BOUNCE AND HIT AGAIN. A SMALL FIRE WAS STARTED BUT WAS QUICKLY EXTINGUISHED BY THE GROUND CREW. THE PILOT WAS KNOCKED UNCONSCIOUS BY THE IMPACT AND WAS PULLED FROM THE WRECKAGE BY THE CREW CHIEF. AFTER ALL THE CREW AND PASSENGERS WERE CLEAR OF THE WRECKAGE, THE CREW CHIEF WENT BACK TO TURN ALL THE SWITCHES OFF TO KILL THE ENGINE. THE CREW SUFFERED MINOR INJURIES WHILE THE PASSENGERS WERE UNHURT. PHOTOGRAPHS 5 AND 6 SHOW THE AIRCRAFT IN ITS FINAL RESTING PLACE TAKEN FROM THE EAST AND NORTH.\\
