NTSB narrative
PRIOR TO DEPARTURE FROM AN UNIMPROVED HELICOPTER LANDING PAD THE PILOT FAILED TO ASSURE REQUIRED CLEARANCE FROM OBSTACLES POSITIONED ALONG HIS ROUTE OF DEPARTURE. THE HELICOPTER STRUCK A SINGLE ELECTRICAL POWER LINE RESULTING IN LOSS OF CONTROL DUE TO THE CONTROL RODS BEING SEVERED. A FORCED LANDING WAS PERFORMED BY REDUCING THE ENGINE POWER, HOWEVER, CONTROLLABILITY WITH COLLECTIVE OR CYCLIC WAS NOT AVAILABLE. THE HELICOPTER IMPACTED THE GROUND SLIDING RIGHT AND TURNING LEFT RESULTING IN IT ROLLING ON ITS RIGHT SIDE.
Probable cause
FAILURE OF THE PILOT TO MAINTAIN PROPER VISUAL LOOKOUT PRIOR TO AND DURING DEPARTURE.

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: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
