ON 24 FEB 70, WO1 HOELSY AND WO1 WAUGH WERE FLYING A UH-1H AIRCRAFT SN 68-15378 IN SUPPORT OF THE SENIOR ADVISOR TO THE 44TH SPECIAL TACTICAL ZONE. THEY DROPPED THE SENIOR ADVISOR OFF AT CHI LANG AND WERE INSTRUCTED TO RETURN TO CAO LAHN TO PICK UP SEVERAL PASSENGERS AND THEN RETURN TO CHI LANG. WO1 HOELSY THEN FLEW THE AIRCRAFT TO TAN TIC TO REFUEL, TOOK OFF AND FLEW TO THE PSP PAD AT CAO LAHN AND PICKED THEIR PASSENGERS. AS SOON AS ALL PASENGERS WERE ABOARD, THE AIRCRAFT DEPARTED FOR CHI LANG. THE FLIGHT TO CHI LANG WAS UNEVENTFUL EXCEPT FOR SOME TURBULENCE DUE TO THE CLOUDS. AT 1415 HOURS, JUST NORTHEAST OF CHI LANG, THE CREW EXPERIENCED A SHUDDER WHICH WAS NOT READILY DISTINGUISHED AS AYAW. AT FIRST IT SEEMED LIKE THE NORMAL TURBULENCE THEY HAD BEEN EXPERIENCING. AS THE MASTER CAUTION LIGHT ILLUMINATED AND THE N-1, ENGINE TACHOMETER AND TORQUE METER BEGAN TO DECREASE, IT BECAME QUITE EVIDENT THAT THEY HAD AN ENGINE FAILURE. IT MIGHT BE NOTED HERE THAT THERE WAS A SLIGHT DELAY IN DIAGNOSING THE MALFUNCTION FOR SEVERAL REASONS. FIRST, THE RPM WARNING CURCUIT BREAKER HAD BEEN PULLED. ALSO, THERE WASN'T A YAW TO THE LEFT WHICH IS A GOOD INDICATION OF AN ENGINE FAILURE. WO1 HOELSY THEN ENTERED AUTOROTATION AT THE SAME TIME TELLING HIS CO-PILOT THAT THEY HAD AN ENGINE FAILURE AND INSTRUCTING HIM TO MAKE THE RADIO CALLS. WO1 WAUGH TUNED HIS UHF TRANSMITTER TO THE GUARD POSITION AND GAVE A MAYDAY CALL. HE DID REACH ANOTHER AIRCRAFT, 114TH AVN CO, IN THE AREA AND GAVE A POSITION REPORT. AT ABOUT 400 FEET, WO1 WAUGH CHECKED THE ROTOR RPM AND NOTICED THAT IT WAS BELOW THE GREEN, ABOUT 290. HE TOLD WO1 HOESLY ABOUT IT AND HOSELY WENT FROM HIS ESTABLISHED 70 KT ATTITUDE TO ABOUT A 90 KT ATTITUDE. AT ABOUT 150 FEET, WO1 HOESLY BEGAN A DECELERATION IN AN ATTEMPT TO REGAIN HIS RPM. HE DID GET BACK INTO THE LOW GREEN. AT ABOUT 15 FEET INITIAL PITCH WAS APPLIED. WO1 HOESLY REPORTED THAT ALTHOUGH PITCH WAS APPLIED IT DIDN'T SEEM TO DO ANY GOOD BECAUSE HE FELL THROUGH FROM ABOUT 10 FEET. WO1 HOSELY LATER STATED THAT HE MAY HAVE NOT HAD HIS PITCH COMPLETELY BOTTOMED. THE AIRCRAFT BOUNCED ONCE, SKIDDED ABOUT 4 FEET AND CAME TO REST. WHEN THE CREW AND PASSENGERS EXITED, IT WAS NOTICED THAT THE TAIL BOOM HAD BEEN CHOPPED OFF. THE 114TH AVN CO AIRCRAFT PICKED UP THE CREW AND PASSENGERS IN TWO TRIPS AND BROUGHT THEM TO CHI LANG. THERE WERE NO INJURIES.\\
