Hobart Bay, Alaska 99850
Sunday, February 23, 1992 15:30 AST
NTSB Narrative Summary Released at Completion of Accident
THE PILOT IN COMMAND HAD A MECHANIC ATTACH A 30 FOOT CHOKER CABLE TO THE EXTERNAL CARGO HOOK SO THAT WHEN HE CAME TO A HOVER TO PICK UP PASSENGERS, THE CABLE WOULD TOUCH THE GROUND AND DISSIPATE THE STATIC ELECTRICITY. AFTER PICKING UP THE LAST TIMBER CUTTERS, EN ROUTE TO BASE CAMP, THE HELICOPTER FLEW THROUGH TURBULENCE AND A PASSENGER IN THE CABIN YELLED. THE PILOT TURNED TO LOOK AT THE PASSENGER, LOOKED FORWARD, HEARD A BANG AND EXPERIENCED A YAW. THE TAIL ROTOR AND 90 DEGREE GEARBOX SEPARATED FROM THE HELICOPTER AND HE AUTOROTATED INTO TALL TREES. SUBSEQUENT EXAMINATION SHOWED THE MARKS IN THE TAILROTOR BLADE MATCHED THE SOCKET SHAPE AT THE END OF THE CABLE.
NTSB Probable Cause Narrative
SEPARATION OF THE TAIL ROTOR AND 90 DEGREE GEARBOX DUE TO THE PILOT'S FAILURE TO FOLLOW PROCEDURES/DIRECTIVES WHICH RESULTED IN THE EXTERNAL LOAD CABLE BECOMING ENTANGLED IN THE TAIL ROTOR. FACTORS WERE THE TURBULENT WEATHER AND THE LACK OF SUITABLE TERRAIN FOR A FORCED LANDING.
