NTSB narrative
THE PILOT WAS CONDUCTING A SLING LOAD OPERATION WITH A 50 FT CABLE ATTACHED. AFTER THE LAST SLING LOAD WAS MOVED TO A NEW DRILLING SITE, THE PILOT ELECTED TO LEAVE THE CABLE ATTACHED SINCE THERE WAS NO SUITABLE LANDING AREA NEARBY. HE STATED THAT THE CABLE WAS TRAILING NICELY AS HE DESCENDED DOWN A 1500 FT BLUFF ABOVE THE MAIN CAMP. HOWEVER, AS HE REDUCED THE RATE OF DESCENT AND FORWARD VELOCITY, AND APPLIED POWER, THE CABLE BECAME ENGAGED IN THE TAIL ROTOR. SUBSEQUENTLY, THE PILOT LOST EFFECTIVE CONTROL OF THE HELICOPTER AND CRASHED ON A ROCKY BEACH. THE TAIL ROTOR AND TAIL ROTOR GEAR BOX WERE FOUND ABOUT 100 FT FROM THE HELICOPTER.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1982-07-21.
