Circumstances:
The aircraft departed Las Vegas, NV as the 2nd of 5 aircraft on a scheduled Grand Canyon sightseeing flight. The 1st portion of the flight was over the Las Vegas strip area and Lake Mead and was uneventful. However, weather conditions precluded the pilot from continuing over the Shivwits plateau. Radio conversations between the pilot and other company aircrews indicated that the pilot of N88LV had encountered deteriorating weather conditions in the canyon and that he had decided to abort the flight and climb out. Later attempts to contact the aircraft were unsuccessful. The wreckage was found on 8/18/83 where the aircraft had collided on the west wall of a mesa inside the canyon. A helicopter pilot flying about 14 miles north of the crash site reported clouds at ground level (4,500 feet msl). The elevation of the accident site was 6,320 feet. Shortly before his last transmission, the pilot stated he was 'just short of Twin Peaks.' The pilot had transmitted his position from Peach VOR, indicating he was in the area of the crash site. Twin Peaks was northeast and had similar terrain. All 10 occupants were killed.
