Accident Summary:
THE AIRCRAFT AND CREW ARE CONDUCTING A COMBAT ASSAULT MISSION WITH 8 OTHER
AIRCRAFT. PRIOR TO THE ACCIDENT THEY HAD FLOWN 4 SORTIES. THERE HAD BEEN NO
INDICATION OF ANY MECHANICAL PROBLEMS DURING THIS TIME. AFTER COMPLETION OF THE
FOURTH LIFT, THE ENTIRE FLIGHT RETURNED TO THE PZ AT COORDINATES YT 598 208 TO
PICK UP A SECOND LIFT OF TROOPS. CW WIDMER WAS FLYING THE AIRCRAFT. HIS AIRCRAFT
WAS CHALK 2 IN A FLIGHT OF FOUR. THE ORIGINAL FLIGHT OF 9 AIRCRAFT HAD BEEN
BROKEN DOWN INTO 2 ELEMENTS ALPHA AND BRAVO WITH A TWO MINUTE SEPARATION. CW
WIDMER WAS IN THE BRAVO ELEMENT. BRAVO LEAD WAS TOLD TO MAKE A 360 DEGREE TURN
TO ALLOW FOR ADDITIONAL TIME NEEDED TO LOAD THE TROOPS ON THE ALPHA ELEMENT.
AFTER THIS 360 DEGREE TURN, BRAVO LEAD STARTED A FAST, STEEP DESCENDING RIGHT
TURN TO GET INTO THE PZ. ON SHORT FINAL, CW WIDMER WAS ABOUT ONE ROTOR DIAMETER
BEHIND LEAD IN A TRAIL FORMATION. LEAD CAME IN HIGH AND FAST. CW WIDMER ALLOWED
HIS AIRCRAFT TO BECOME LOWER THAN LEAD. AS A RESULT, WHEN LEAD FLARED
EXCESSIVELY TO PREVENT HIS RUNNING INTO THE TREE LINE AT HIS FRONT, CW WIDMER
WAS FORCED TO ALSO PUT IN A EXCESSIVE FLARE. HIS CLOSENESS TO THE GROUND ALLOWED
HIS TAIL ROTOR TO COME IN CONTACT WITH THE WATER IN THE PZ BELOW HIM. THE TAIL
ROTOR BLADES AND 90 DEGREE GEAR TORE OFF IMMEDIATELY IN ONE PIECE. CW WIDMER
REALIZED IMMEDIATELY WHAT HAD HAPPENED AND CHOPPED THE THROTTLE AND CORRECTED
WITH CYCLIC TO LEVEL THE AIRCRAFT. THE PILOT PERFORMED A HOVERING AUTOROTATION,
LANDING QUITE HARD BUT WITH VERY LITTLE TURN TO EITHER LEFT OR RIGHT. THE
AIRCRAFT LANDED FIRST ON THE RIGHT SKID AND THEN THE LEFT, CAUSING STRUCTURAL
DAMAGE TO THE RIGHT LONGERON.\\

Accident Summary:
ON 25 JANUARY 1972, AT APPROXIMATELY 1630 AIRCRAFT ^64-13546^, AND THREE
OTHER UH-1H HELICOPTERS DEPARTED FOB 11 PAD TO EXTRACT A 52 MAN TEAM FROM A PZ
SOUTHEAST OF KONTUM. EACH AIRCRAFT WAS TO FLY TWO SORTIES. THEY WERE DIVIDED UP
INTO TWO FLIGHTS OF TWO EACH. THE PZ WAS LARGE ENOUGH TO ACCOMMODATE THREE OR
FOUR SHIPS IF THE NEED AROSE. THE TREES SURROUNDING THE PZ WERE FROM 25 TO 30
FEET TALL, WITH THE LONG AXIS RUNNING FROM NORTH TO SOUTH. ALL APPROACHES AND
DEPARTURES WERE MADE NORTH TO SOUTH WHILE SURFACE WINDS WERE LIGHT AND VISIBLE
AT FIVE KNOTS FROM THE EAST. TERRAIN AT THE CRASH SITE WAS LOW GRASS WITH A FEW
DEAD TREES LAYING ON THE NORTHERN EDGE, PERMITTING THE AIRCRAFT TO LAND WHILE
LOADING TROOPS ABOARD. ON THE FIRST EXTRACTION THE PILOT HAD BEEPED THE ENGINE
RPM FROM 6,600 TO 6,400 DURING THE DESCENT TO PRECLUDE ANY ROTOR OVER SPEED. SIX
(6) PAX WERE LOADED AND THE AIRCRAFT WAS BROUGHT TO A HOVER STABILIZED AT 6,400
RPM. THE PILOT THEN DEPARTED THE PZ ENROUTE TO THE FOB PAD FOR PASSENGER DROP
OFF. ON THE SECOND SORTIE THE SAME PROCEDURE WAS FOLLOWED FOR ENTERING THE PZ.
THIS TIME EIGHT (8) PAX WERE LOADED ABOARD. THE AIRCRAFT HAD LANDED ABOUT 25
METERS SHORT OF THE TREES ON THE DEPARTURE END. THE PILOT THEN BEEPED THE ENGINE
RPM BACK OP TO 6,600 RPM AND THE AIRCRAFT WAS BROUGHT TO ABOUT A FOUR FOOT HOVER
WHERE THE RPM STABILIZED AT BETWEEN 6,450 RPM AND 6,500 RPM WITH 40 LBS. OF
TORQUE. FUEL ON BOARD AT THE TIME WAS ABOUT 650 LBS. THE PILOT THEN PULLED IN 45
LBS OF TORQUE AND STARTED HIS ASCENT. THE ENGINE RPM HAD THEN STABILIZED AT
6,400 RPM. AT APPROXIMATELY 20 TO 25 FEET WITH APPROXIMATELY 5 TO 10 KNOTS OF
FORWARD AIRSPEED, THE ENGINE SUDDENLY BEGAN TO BLEED OFF AND THE PILOT ATTEMPTED
TO BACK THE AIRCRAFT BACK INTO THE PZ. ENGINE RPM HAD DROPPED TO APPROXIMATELY
5900 RPM AND A DECREASE IN COLLECTIVE PITCH DID NOT BRING THE RPM BACK TO
OPERATING LIMITS. THE AIRCRAFT STARTED TO SPIN TO THE RIGHT AS FULL LEFT PEDAL
WAS APPLIED. THE PILOT NOR COPILOT DIDN'T NOTICE ANY CHANGE IN ENGINE SOUND
DURING THIS EMERGENCY. THE PILOT NOTICED A STUMP THAT WOULD HAVE GONE THROUGH
THE CHIN BUBBLE AND AFT CYCLE WAS APPLIED TO AVOID IT. WITH THE AIRCRAF TSTILL
IN THE RIGHT HAND SPIN THE TAIL ROTOR STRUCK THE TREES AT THE EDGE OF THE PZ
WHICH CAUSED THE HELICOPTER TO SWING 180 DEGREES TO THE RIGHT VERY RAPIDLY AND
THEN THE ROTOR BLADES AND FUSELAGE IMPACTED THE GROUND ON THE RIGHT SIDE IN A
NOSE LOW ATTITUDE WHERE IT CAME TO REST. THE PILOT AND CO-PILOT EXITED THROUGH
THE FORWARD WINDSHIELD THAT HAD BEEN BROKEN OUT BY THE TEAM LEADER FOR THEIR
EXIT. THEY THEN HELPED THE REMAINING TWO CREW MEMBERS AND PASSENGERS TO EXIT THE
AIRCRAFT. HOURS AFTER THE ACCIDENT DUE TO A GROUND FIRE WHICH WAS STARTED BY
SMOKE GRENADES USED DURING THE TROOP EXTRACTION. AN ATTEMPT TO EXTINGUISH THE
FIRE WAS TRIED BY THE ARVN FORCE IN IN THE PZ, BUT THE FIRE WAS NOT PUT
COMPLETELY UNDER CONTROL. THE AIRCRAFT WAS TOTALLY BURNED EXCEPT FOR THE LAST
THREE-FOURTHS OF THE TAIL BOOM.
