The helicopter pilot's failure to maintain adequate clearance during power line construction work, which resulted in the helicopter's main rotor striking and becoming entangled with a wire and a subsequent dynamic rollover and collision with terrain. Contributing to the accident was the pilot's and linemen's decision to continue work without a secondary safety device installed, which was contrary to standard operating procedures.
