Accident Summary:
CWO JONES FLYING AIRCRAFT 67-15764 FLEW THREE HOURS AND 15 MINUTES OF AN ESCORT MISSION ON THE MORNING OF 27 MARCH 1970. THE LAST THIRTY MINUTES OF THE FLIGHT WAS MARKED BY A COMBINATION 1:1 LATERAL AND 2:1 VERTICAL VIBRATIONS WHICH CWO JONES REPORTED TO THE UNIT MAINTENANCE OFFICER. CWO JONES DETERMINED THAT THE VIBRATION WAS NOT EXCESSIVE ENOUGH TO CHANGE AIRCRAFT. HE TOOK OFF FROM HUE/PHU BAI AIRFIELD APPROXIMATELY 1450 HOURS AND EXPERIENCED THE SAME LOW FREQUENCY VIBRATION FOR APPROXIMATELY THE FIRST TWENTY MINUTES OF THE FLIGHT. DURING THIS TIME CWO JONES WAS FLYING AT 600 FEET AND 110 KNOTS. AFTER THE FIRST TWENTY MINUTES, THE VIBRATION BECAME WORSE. HIS INITIAL REACTION WAS TO REDUCE AIRSPEED FROM 110 KNOTS TO 90 KNOTS AND NEXT TO DISENGAGE THE STABILITY AND CONTROL AUGMENTATION SYSTEM (SCAS) IN AN EFFORT TO DAMPEN THE VIBRATIONS. THESE ACTIONS HAD NO EFFECT ON THE VIBRATIONS AND HE RE-ENGAGED THE SCAS SYSTEM. ALMOST IMMEDIATELY AFTER ENGAGING THE SCAS SYSTEM, CWO JONES AND WO KEEDY HEARD A LOUD BANG. THE AIRCRAFT YAWED VIGOROUSLY TO THE RIGHT AND THE NOSE LOWERED. CWO JONES REDUCED COLLECTIVE PTICH THINKING HE HAD ENGINE FAILURE. HE IMMEDIATELY RE-EVALUATED THE EMERGENCY AND DETERMINED HE HAD POWER FROM HIS ENGINE BUT NO TAILROTOR CONTROL. HE THEN ADJUSTED THE COLLECTIVE PITCH TO CONTROL HIS RATE OF DESCENT. AT THIS TIME THE AIRCRAFT WAS IN A NOSE LOW, DECENDING RIGHT TURN. CWO JONES ATTEMPTED TO LEVEL THE AIRCRAFT WITH THE CYCLIC CONTROL BUT THIS HAD A NEGLIGIBLE EFFECT. HE COULD NOT STOP THE AIRCRAFT FROM TURNING RIGHT IN A NOSE LOW ALTITUDE, BUT HE FOUND THAT SLIGHT AFT AND LEFT CYCLIC ALLOWED HIM SOME MEASURE OF CONTROL DURING THE DECENDING TURN. ALTHOUGH THE NOSE OF THE AIRCRAFT NEVER CAME LEVEL, THE AIRSPEED AND GROUND SPEED DID SLOW. THE INITIAL FLIGHT PATH OF THIS AIRCRAFT WAS A LARGE CIRCULAR PATTERN; BUT AS THE AIRSPEED WAS REDUCED, THE CIRCULAR FLIGHT PATH BECAME INCREASINGLY SMALLER. AT 100 FEET AGL AND 20 KNOTS THE AIRCRAFT WAS IN A TIGHT, NOSE LOW RIGHT TURN HEADING FOR A ROW OF BAMBOO TREES. CWO JONES AVOIDED THE TREES BUT HIS AIRSPEED AHD DECELERATED TO ZERO AND HIS ALTITUDE WAS THIRTY FEET AGL. AT THIS TIME THE AIRCRAFT WAS ALMOST VERTICAL TO THE GROUND AND SPINNING AROUND ITS NOSE. THE AIRCRAFT MADE THREE REVOLUTIONS BEFORE CWO JONES ROLLED OFF THE THROTTLE. THIS STOPPED THE AIRCRAFT FROM SPINNING AND HE AUTOROTATED THE REMAINING THIRTY FEET INTO A CLEAR FLAT AREA. ALL REMAINING COLLECTIVE PITCH WAS APPLIED IN AN ATTEMPT TO CUSHION THE LANDING, HOWEVER, DUE TO A HIGH SINK RATE THE AIRCRAFT LANDED HARD IN A SLIGHT NOSE LOW ALTITUDE. AFTER THE INITIAL IMPACT THERE WAS NO FURTHER MOVEMENT AND THE AIRCRAFT REMAINED IN AN UPRIGHT POSITION. CWO JONES SHUT THE AIRCRAFT DOWN AND BOTH CREW MEMBERS DEPARTED THE AIRCRAFT UNDER THEIR OWN POWER. NO POSTCRASH FIRE OCCURED.\\
