Accident Summary:

ON 25 JUNE 1969, WO1 COOPER TOOK OFF ON A MISSION TO SUPPORT THE 4TH INF DIV. AT APPROXIMATELY 0915 HOURS, WHILE INROUTE TO THE FIRST PZ, THE FLIGHT WAS CROSSING RUGGED MOUNTAINOUS TERRAIN WHICH MR. COOPER WAS UNFAMILIAR WITH SINCE HIS UNIT SELDOM HAD MISSIONS IN THIS AREA. MR. STEWART WAS AT THE CONTROLS WHILE FLYING IN FORMATION AT AN INDICATED ALTITUDE OF 3,000' OR AT ABOUT 1600' AGL. THE FLIGHT WAS HEADED APPROXIMATELY NORTH WHEN THE CREW, WITH THE EXCEPTION OF MR. COOPER, HEARD 3 THUMPS, AND SIMULTANOUSLY THE MASTER CAUTION AND CHIP DETECTOR LIGHTS CAME ON. AT THIS POINT MR. COOPER TOOK THE CONTROLS, BEGAN A DESENDING LEFT TURN TOWARD A MORE SUITABLE AREA AND RADIOED A MAY DAY CALL. THE PILOT, MR. STEWART, SCANNED THE INSTRUMENTS AND FOUND THEM ALL IN THE GREEN WITH THE EXCEPTION OF THE CHIP DETECTOR AND MASTER CAUTION LIGHTS. COOPER HAD DESCENDED SOME 800' IN 30 SECONDS BEFORE HE FELT THE ENGINE LOOSING POWER AND VERIFIED THIS BY AN AUDIBLE DECREASE IN THE ENGINE NOISE LEVEL, AS WELL AS A DECREASING GAS PRODUCER READING. IT WAS AT THIS POINT THAT MR. COOPER DECIDED TO ENTER AUTOROTATION AND HE ROLLED OFF THE THROTTLE, BOTTOMED COLLECTIVE, AND BEGAN A DESCENT TOWARDS WHAT HE BELIEVED TO BE AN OPEN AREA. IT WAS AT ABOUT 200' AGL THAT MR. COOPER REALIZED THAT THE AREA HE WAS SHOOTING FOR WAS UNSUITABLE IN THAT IT WAS COVERED WITH STUMPS AND HAD A HIGH DEGREE OF SLOPE TO IT. SPOTTING ANOTHER AREA SOME 50 TO 75 METERS BEYOND AND TO THE RIGHT (NORTH) OF THE ORIGINAL AREA, MR. COOPER CHANGED HIS INTENTIONS AND DECIDED TO TRY FOR THE MORE SUITABLE AREA. AT THIS TIME HE PULLED IN SOME PITCH TO EXTEND HIS GLIDE HOPING TO MAKE THE ALTERNATE AREA. IT WAS THEN THAT THE PILOT, MR. STEWART, NOTICED THAT THE ENGINE OIL PRESSURE LIGHT CAME ON AND THE GAUGE READ 30 POUNDS. THIS WAS AT APPROXIMATELY 100 AGL. SHORTLY AFTER THE TRANSMISSION OIL PRESSURE LIGHT CAME ON THE GAS PRODUCER HAD DECREASED TO A READING OF SOME 30%. AT ABOUT 20' AGL, MR. STEWART READ THE ROTOR TACH AT 230, WELL OUT OF THE GREEN. MR. COOPER, MEANWHILE CONTINUED HIS DESCENT FOR THE AREA, LEAVING SOME PITCH IN THE BLADES KNOWING THE ROTOR WAS FAR FROM OPTIMUM RPM. FEELING THAT A DECELERATION FLARE WOULD CAUSE HIM TO FALL SHORT OF HIS INTENDED LANDING POINT, HE WENT IN THE LAST 75' IN A SOMEWHAT LEVEL ATTITUDE. AS THE SHIP STARTED CRASHING INTO A BAMBOO THICKET, MR. COOPER PULLED HIS REMAINING PITCH (10-12 AGL) TO CUSHION ON. THE AIRCRAFT IMPACTED SOME 10 FEET FROM THE INTENDED OPEN AREA AND AFTER HITTING THE GROUND THERE WAS NO FURTHER MOVEMENT OF THE AIRCRAFT.\\
