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.

Circumstances:
After takeoff, the pilot was cleared to proceed on an IFR flight plan. After being cleared to 15,000 ft msl, he reported having trouble maintaining his airspeed and subsequently declared an emergency. Shortly after that, radar contact was lost. The aircraft impacted at night near the top of a mountain ridge at about 4,700 ft msl. The wreckage was demolished and scattered over a large area, but there was no evidence of an inflight breakup. Some parts of the wreckage (including the right engine) were not found on the snow covered terrain. The weather forecast called for: thunderstorms in lines, mountains obscured, moderate and occasionally severe turbulence below 20,000 ft, occasional moderate icing in clouds and in precipitation from the freezing level (3,000 ft) to 20,000 ft. The aircraft was not certified for flight in known icing conditions.
Probable cause:
Occurrence #1: in flight encounter with weather
Phase of operation: climb - to cruise

Circumstances:
Approximately 1/2 mile from the airport after takeoff, the pilot noticed the left front baggage door partly open and made a left turn back toward the airstrip. After the turn, the baggage door came completely open, the left wing dropped immediately and the aircraft stalled. The pilot added full power and lowered the nose. When he raised the nose near the ground, the aircraft shuddered and crashed. Two rescue personnel, both certified pilots, arrived shortly after the accident and found the nose baggage door in the unlocked position with the bayonet pins retracted. A Piper representative stated that if the left side nose baggage door of a PA-31 opened in flight there would be the likelihood of an interruption to the smooth airflow through the prop, possibly reducing the thrust produced by the blades.
Probable cause:
Loss of control in flight while maneuvering to landing area after the pilot failed to maintain flying speed. The following findings were reported:
- Cargo door unlocked,
- Inadequate preflight preparation,
- Aircraft performances deteriorated,
- Inadvertent stall by the pilot.
