When nearing its destination after a flight of about three hours, the helicopter struck a set of power lines, eight metres above ground level, spanning a ridge line. Witnesses described flight path as "quite low and fast" compared to other helicopters they had observed approaching the Airport. Examination of the wreckage revealed wire strike damage to the upper surface of one blade, suggesting that the helicopter was in powered forward flight when it contacted the wires. A test run of the engine found it to be capable of normal operation.
