Accident Summary:

. THE AIRCRAFT COMMANDER AND THE PILOT WERE FLYING A SERVICE MISSION IN CHAU DUC PROVINCE, REPUBLIC OF VIETNAM. AFTER FLYING NEARLY FIVE HOURS, THE CREW PICKED UP SIX PASSENGERS, FOUR AMERICANS AND TWO ARVN. THE ROUTE OF FLIGHT WAS TO BE FROM CHI LANG TO SADEC TO DROP OFF THE PASSENGERS, AND THEN TO VINH LONG FOR TERMINATION OF THE MISSION. THE TAKE OFF WAS ACCOMPLISHED WITH APPROXIMATELY 800-900 LBS. OF FUEL. THE TAKEOFF WAS UNEVENTFUL, AND THE AIRCRAFT PROCEEDED TO CLIMB OUT FROM CHI LANG ON A NORTHEASTERLY COURSE. AT APPROXIMATELY 1200 FEET THE CREW HEARD A SINGLE EXPLOSION, DESCRIBED AS A LOUD POP FROM THE TRANSMISSION OR THE ENGINE AREA. THE AIRCRAFT THEN SHUDDERED AND DROPPED SLIGHTLY. THE AIRCRAFT COMMANDER INITIATED AN IMMEDIATE POWER-ON DESCENT, AND TRANSMITTED A MAYDAY ON GUARD. THE AIRCRAFT COMMANDER CALLED THAT THEY WERE TWO MILES EAST OF CHI LANG, NEXT TO A MAJOR CANAL. THE CALL WAS REPEATED ONCE AND SEVERAL AIRCRAFT RESPONDED. AFTER INITIATING THE DESCENT THE AIRCRAFT COMMANDER NOTICED A LOUD SCREAMING NOISE FROM THE TRANSMISSION AREA THAT WAS INCREASING RAPIDLY IN INTENSITY. THE AIRCRAFT COMMANDER DID NOT GET SPECIFIC READINGS FROM THE INSTRUMENTS, BUT WAS CERTAIN THAT THE ENGINE RPM WAS NORMAL. AT 500-700 FEET, THE SCREAMING NOISE REACHED SUCH AN INTENSITY THAT THE AIRCRAFT COMMANDER DECIDED TO SHUT THE ENGINE DOWN AND ENTER AUTOROTATION. AT THIS TIME THE AIRCRAFT WAS APPROXIMATELY OVER A MAJOR CANAL, AND THE AIRCRAFT COMMANDER CHOSE AS HIS TOUCHDOWN POINT AN OPEN AREA DIRECTLY IN FRONT OF HIM. THE AIRCRAFT WAS HEADING GENERALLY EAST. THE AIRCRAFT COMMANDER ROLLED THE THROTTLE TO THE CLOSED POSITION AND SHUT OFF THE FUEL. THE AUTOROTATION WAS INITIATED, AND PROCEEDED NORMALLY. THE AIRCRAFT COMMANDER NOTICED BEFORE HE INITIATED HIS DECELARATION THAT THE TOUCHDOWN AREA WAS A ROUGH, HARD, PLOWED FIELD. IT WAS AT THIS TIME THAT HE DECIDED TO ATTEMPT A ZERO GROUND RUN TYPE AUTOROTATION. THE AIRCRAFT COMMANDER INITIATED AN ABRUPT DECELERATION, AND ATTEMPTED TO SLOW THE AIRCRAFT. AT APPROXIMATELY 8-10 FEET HE RAN OUT OF PITCH AND THE AIRCRAFT CONTACTED THE GROUND WITH LITTLE FORWARD VELOCITY AND A HIGH RATE OF DESCENT. THE AIRCRAFT IMPACTED HARD AND IN AN APPROXIMATELY LEVEL ATTITUDE. THE RIGHT SKID COLLAPSED AND THE AIRCRAFT ROLLED OVER ON ITS RIGHT SIDE. THE MAIN ROTOR BLADE STRUCK THE GROUND 2-4 TIMES, AND REMAINED RELATIVELY INTACT DUE TO EXTREMELY LOW ROTOR RPM. THERE WAS NO FIRE DUE TO THE FACT THAT THE FUEL TANKS WERE NOT RUPTURED AND THE ENGINE WAS SHUT DOWN. ALL CREWMEMBERS AND PASSENGERS EXITED THE AIRCRAFT WITHOUT DIFFICULTY, THOUGH THREE PERSONS SUFFERED MINOR INJURIES. AN AIRCRAFT ARRIVED WITHIN FIVE MINUTES, AND THE CREW AND AIRCRAFT WERE SECURED WITHOUT INCIDENT.\\
