Read the full 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.
