Accident Summary:
ON 1L APRIL 1969 ^CWO NESBITT, CHARLES H.,^ AN INSTRUCTOR PILOT FOR THE ^57TH
AVIATION COMPANY (AML),^ WAS GIVING ^WO
MAXWELL, MAURICE D,^ HIS AIRCRAFT
COMMANDER CHECKRIDE IN A UH-1H, SER NO 66-16534. ^CWO NESBITT AND WO
MAXWELL^
PERFORMED THE PREFLIGHT INSPECTION ON THE AIRCRAFT. THIS NECESSITATED LEAVING
THE OTHER CARGO DOOR OPEN ALSO. AFTER CRANKING THE PILOTS PERFORMED FIVE
HOVERING AUTOROTIONS AND THEN ENTERED TRAFFIC AT KONTUM ARMY AIRFIELD TO
PRACTIVE STRAIGHT-IN AUTOROTATIONS. ^CWO NESBITT^ DEMONSTRATED TWO AUTOROTATIONS
AND THEN INSTRUCTED ^WO
MAXWELL^ TO PERFORM THE NEXT AUTOROTATION. ^WO
MAXWELL^
ENTERED AUTOROTATION OVER THE THRESHOLD O FRUNWAY 09. APPROXIMATELY TEN SECONDS
AFTER ENTERING AUTOROTATION A FIELD JACKET BLEW OUT OF THE CE COMPARTMENT AND
BECAME ENTANGLED IN THE TAIL ROTOR. THE FIELD JACKET CAUSED THE TAIL ROTOR
BLADES TO SEPARATE FROM THE 90 DEGREE GEARBOX TO SEPARATE FROM THE TAIL BOOM.
UPON DETERMINING THAT THERE WAS A TAIL ROTOR FAILURE ^CWO NESBITT^ TOOK CONTROL
OF THE AIRCRAFT AND CONTINUED THE AUTOROTATION. AT APPROXIMATELY 100 FEET AGL
^CWO NESBITT^ INITIATED A SLIGHT DECELERATION TO DETERMINE THE ACTION OF THE
AIRCRAFT. THE DECELERATION CAUSED THE NOSE OF THE AIRCRAFT TO TURN FARTHER TO
THE RIGHT THAN THE TEN DEGREES RIGHT OF CENTER ATTITUDE WHICH THE AIRCRAFT HAD
TAKEN UPON LOSS OF THE TAIL ROTORS AND GEARBOX. WHEN HE DETERMINED THAT IT WOULD
BE IMPOSSIBLE TO DISSIPATE AIRSPEED WITH A CYCLIC FLARE AND STILL MAINTAIN
DIRECTIONAL CONTROL OF THE AIRCRAFT, ^CWO NESBITT^ INITIATED A CYCLIC TURN TO
THE RIGHT IN ORDER TO LOOSE AIRSPEED AND REMAIN WITHIN THE CG LIMITS IMPOSED
UPON HIM BY THE LOSS OF THE 90 DEGREE GEARBOX AND TAIL ROTORS. WHILE EXECUTING
THE TURN ^CWO NESBITT^ CONTROLLED THE RATE OF TURN AND DESCENT WITH THE
COLLECTICOLLECTIVE. ^CWO NESBITT^ CONTINUED THE TURN TO A HEADING OF
APPROXIMATELY 270 DEGREES. THIS PLACED THE AIRCRAFT APPROXIMATELY 75 TO 100 FEET
SOUTH OF THE RUNWAY, 10 TO 15 FEET AGL AND 180 DEGREES FROM HIS HEADING UPON
ENTRY INTO THE AUTOROTATION. AT THIS TIME ^CWO NESBITT^ ASSUMED A LANDING
ATTITUDE AND APPLIED COLLECTIVE PITCH TO COMPLETE THE AUTOROTATION. THE
APPLICATION OF AFT CYCLIC AND COLLECTIVE PITCH CAUSED THE AIRCRAFT TO TURN 90
DEGEES TO THE RIGHT BEFORE MAKING GROUND CONTACT. THE AIRCRAFT MADE GROUND
CONTACT HEADING APPROXIMATELY 360 DEGREES. THE LEFT REAR SKID MADE GROUND
CONTACT FIRST. THE LEFT SKID FOLDED UNDER DUE TO EXCESSIVE SIDE LOADING UPON
GROUND CONTACT. THE RIGHT SKID WAS BENT OUT TO THE RIGHT UPON GROUND CONTACT.
THE AIRCRAFT DID NOT BOUNCE UPON MAKING GROUND CONTACT. ^CWO NESBITT^ INSTRUCTED
^WO
MAXWELL^ TO DEPART THE AIRCRAFT WHILE HE WAS SHUTTING THE AIRCRAFT DOWN. THE
SITUATION WHICH CAUSED THIS ACCIDENT WAS CREATED BY AN IMPROPER PREFLIGHT BY THE
PILOTS. AN UNSECURED FIELD JACKET IN THE CE COMPARTMENT WAS OVERLOOKED DURING
THE PREFLIGHT. THE FIELD JACKET BLEW OUT OF THE AIRCRAFT AND BECAME ENTANGLED IN
THE TAIL ROTOR CAUSING THE 90 DEGREE GEARBOX AND THE TAIL ROTOR BLADES TO
SEPARATE FROM THE AIRCRAFT. THE TAIL BOOM SUSTAINED STRESS CRACKS DUE TO THE
SUDDEN STOPPAGE OF THE TAIL ROTOR. BOTH SKIDS, BOTH CROSSTUBES AND THE CROSSTUBE
HARD POINTS WERE DAMAGED DUE TO EXCESS SIDE LOADING ON THE SKIDS UPON GROUND
CONTACT.
