Narrative:
After dropping off passengers at a mining site, the helicopter was observed climbing in a shallow nose down attitude, heading north, when it impacted two electrical wires. The helicopter then descended and impacted on a road between vertical walls of a previously mined area, where it was consumed by a post-crash fire. Examination of the wreckage did not reveal any evidence of a pre-impact malfunction. Examination of the main rotor blades revealed several scrape marks and gouges consistent with a wire strike. Visibility reported at a nearby airport was 10 statute miles, and a witness to the accident said the wind was 'calm,' and visibility was 'good.'

Probable Cause: The pilot's inadequate visual look out which resulted in an in-flight collision with wires.
