Accident Summary:

THE CREW OF UH-1H, SN 66-16266, WERE ON A TRAINING MISSION THE DAY OF 4 FEBRUARY 1970. THE AIRCRAFT HAD RECEIVED A THOROUGH PREFLIGHT THAT MORNING AND DEPARTED PHUOC VINH AT APPROXIMATELY 0830 HOURS FOR TRAINING AT PLANTATION AIRFIELD IN LONG BINH, RVN. ONE COMPLETE TRAINING RIDE HAD BEEN GIVEN WITH THE AIRCRAFT PRIOR TO THE ACCIDENT INVOLVING CW2 WESTERLUND AND WO1 NELSON, DURING WHICH TIME THE UH-1H FLEW SMOOTHLY WITH NO UNUSUAL VIBRATIONS OR SOUNDS THAT WOULD AROUSE SUSPICION THAT THERE WAS SOME DEFECT WITH THE AIRCRAFT. DURING THE SECOND TRAINING FLIGHT, THE AIRCRAFT HAD LIFTED OFF PLANTATION AND WAS IN CLOSED RIGHT TRAFFIC WITH THE ACTIVE RUNWAY BEING 05. PRIOR TO TURNING RIGHT BASE 05, CONSIDERABLE RIGHT PEDAL HAD BEEN APPLIED TO THE AIRCRAFT TO SIMULATE A RIGHT TAIL ROTOR FAILURE. THE AIRCRAFT WAS APPROXIMATELY 300 FEET AGL WHEN A RIGHT BASE TURN WAS INITIATED. UPON ENTRY INTO THE TURN, A THUMP IN THE REAR OF THE AIRCRAFT WAS FELT BY BOTH PILOTS. DURING THIS TIME THE AIRCRAFT YAWED SLIGHTLY BUT RETURNED TO THE ORIGINAL FLIGHT POSITION OF A RIGHT CRAB. BOTH CW2 WESTERLUND AND WO1 NELSON LOOKED TO THE REAR OF THE AIRCRAFT UPON HEARING THE THUMP AND OBSERVED DEBRIS FALLING BEHIND THEIR FLIGHT PATH. CW2 WESTERLUND STATED THAT AT FIRST SEEING THE DEBRIS HE THOUGHT IT WAS A LARGE BIRD BUT LATER STATED THAT IT PROBABLY WAS THE TAIL ROTOR BLADE WHICH HAD SEPARATED FROM THE HUB. UPON TURNING BASE TO FINAL 05, CW2 WESTERLUND DECIDED TO ABORT THE SIMULATED RIGHT TAIL ROTOR FAILURE MANEUVER AND LAND TO INSPECT THE AIRCRAFT FOR DAMAGE. AFTER APPLYING LEFT PEDAL TO TAKE THE AIRCRAFT OUT OF A RIGHT CRAB, WITH NEGATIVE EFFECT ON THE FLIGHT ATTITUDE OF THE AIRCRAFT, CW2 WESTERLUND REALIZED THAT HE HAD LOST PEDAL CONTROL OF THE AIRCRAFT, AND ELECTED TO DO A GO-AROUND. UPON INITIATING THE GO-AROUND THE AIRCRAFT BEGAN TO SHUTTER AND LOSE AIRSPEED. CW2 WESTERLUND THEN TRIED TO REGAIN HIS AIRSPEED BY TRYING TO DIVE TO THE RIGHT. AT THIS POINT HIS ALTITUDE WAS APPROXIMATELY 150 FEET AGL. THIS RESULTED IN THE LOSS OF MORE AIRSPEED AND THE AIRCRAFT STARTED A SPIN TO THE RIGHT. AT APPROXIMATELY 25 FEET AGL CW2 WESTERLUND DECIDED TO CUT HIS THROTTLE RESULTING IN THE AIRCRAFT SPINNING 360 DEGREES TO THE RIGHT BEFORE LANDING HARD ON THE GROUND AT THE APPROACH END OF THE 05 ACTIVE, YT 060111. THERE WAS NEGATIVE MOVEMENT OF THE AIRCRAFT AFTER INITIAL IMPACT WITH THE GROUND, AND UPON INSPECTION OF THE AIRCRAFT IT WAS FOUND THAT THE AIRCRAFT IT WAS FOUND THAT THE SKID'S WERE SPREAD AND THAT THE 90 DEGREE GEAR BOX WITH THE TAIL ROTOR ASSEMBLY HAD COMPLETELY SEPARATED FROM THE AIRCRAFT. UPON SEARCH OF THE AREA, THE 90 DEGREE GEAR BOX AND TAIL ROTOR COMPONENT'S WERE FOUND APPROXIMATELY 500 METERS FROM THE POINT OF IMPACT OF THE AIRCRAFT.\\
