According to the aircraft occupants, the aircraft owner, who holds a commercial pilot and cfi certificates, was occupying the right front seat. A friend of the pilot, a 246 hour private pilot with no experience in high performance turbine powered aircraft, was in the left seat and flying the aircraft under the direction of the owner. While on a straight in approach to the airport, the flight was advised three times by the atct of a variable right cross wind from 200 to 220° at speeds from 8 to 14 knots, with higher gust components. The tower also advised the flight of reports of light to moderate turbulence all the way to the ground. Both pilots reported that the aircraft had just touched down on runway 18 when a sudden cross wind gust lifted the right wing. The private pilot did not correct the situation and the aircraft owner could not overpower the other pilots control inputs in time to correct for the wind gust. The left wing tip drug the ground and the aircraft cartwheeled off the left side of the runway and into an airport fence.

The pilot reported that immediately after takeoff, he had a collision with a flight of birds. He stated that the right engine immediately had a partial loss of power. He stated that he did not attempt to raise the landing gear nor the flaps following the loss of engine power, and the aircraft would not maintain altitude. Examination of the aircraft engines revealed that there was rotational scratching of the turbine housings on the right engine, and no rotational scratching on the turbine housing of the left engine.

The airplane was cruising at 16,500 feet at night when radar and radio contact were lost. The pilot made no distress radio calls. Recorded radar data showed the airplane in a left descending turn. Other airplanes were deviating around weather in the area. Ground witnesses heard the airplane prior to impact and reported rain. The pilot started flying lessons in march and received his multi-engine rating in june. He had a total of 142 hours flight time, with 25 hours in this make and model airplane and 9 hours total night time. The pilot was not instrument rated.

Pilot was on final approach when he stated he got a fuel crossfeed 'warning' light. He then proceeded to try to troubleshoot the fuel system by cycling the right boost pump switch, and 'reset and arm' the auto crossfeed. He stated the crossfeed light came on again followed by the right fuel pressure light, and he experienced a power loss on the right side. When he feathered the right engine, the left engine also experienced a loss of power. The pilot cleaned up the airplane and ditched in the lake short of the airport. The investigation revealed the left wing fuel tanks were empty, and the left nacelle tank was collapsed. The right wing fuel tanks were empty, and the right nacelle tank contained 19 gallons of fuel. The fuel supply, transfer, and crossfeed systems were functionally checked, and were operable. All cockpit fuel system lights indicated normal system operation.

During the takeoff roll on runway 03, the crew decided to abandon the takeoff maneuver and initiated an emergency braking procedure. Unable to stop within the remaining distance, the aircraft overran and came to rest in the Bay of Biloxi. There were no casualties while the aircraft was damaged beyond repair. The exact date of the mishap remains unknown, somewhere in July 1992.

Immediately after liftoff the stick shaker activated, and the first officer, who was making the takeoff, said 'you got it.' The captain took control, closed the thrust levers, and landed. He applied full reverse thrust and maximum braking, and turned the airplane off the runway to avoid a barrier at the end. A system design deficiency permitted a malfunctioning aoa sensor to cause a false stall warning. The sensor had experienced 9 previous malfunctions, and was inspected and returned to service without a determination on the reason for the intermittent malfunction. The first officer had incorrectly perceived that the airplane was stalling and gave control to the captain without proper coordination of the transfer of control. All 292 occupants were rescued, among them 10 were injured, one seriously.

The destination camp is located about 50 miles southwest of the departure lodge, and is separated by mountains with some peaks over 4,000 feet asl. The general area weather included low ceilings. The operator stated that shortly before the accident he observed the youth creek weather 'better than 400 feet...', and told the pilot that it appeared good enough to make the flight. The pilot stated that as he flew up youth creek he could see that the pass was closed by low clouds and attempted to reverse direction. The pilot stated he 'made a hard steep turn, and the airplane stalled...' the pilot said the weather was about 800 feet ceiling and visibility of 1 mile. When the pilot was admitted into the hospital immediately following the accident, he was diagnosed as having an insulin dependent diabetic condition. His medical records contain no evidence of, and the pilot denied any knowledge of, any pre-accident diabetic condition. Five passengers were killed while the pilot and a passenger were seriously injured. A day later, the survivor passenger died from his injuries.

The crash occurred at the 1,100 foot level of a mountainside while the airplane was flying a course roughly parallel to the mountain range. Marginal weather conditions were reported for the area. The pilot's 22-year-old son stated that in those type weather conditions his father would routinely climb up into the soup. Set a loran course for home, and sit back and relax. When close to home he would descend to vfr conditions over the flat coastal area and land. The pilot, sole on board, was killed.

During a cross country business flight, which was filed and flown under instrument flight rules, the pilot and controller had numerous communications regarding routing and weather, and the aircraft was circumnavigating weather areas. The pilot reported entering what his stormscope showed as a 'clear' area after encountering rain and moderate turbulence at temperatures conducive to structural icing. The controller noted a 1,000 foot loss of altitude from the assigned cruise altitude of 17,000 feet, followed by a loss of altitude readout. Shortly thereafter the aircraft disappeared from the controller's radar scope. The wreckage was found near the last radar fix. The airplane impacted in a near vertical descent. All four occupants were killed.

The airplane was in cruise flight when the pilot noticed a slight fire smell. The engine began to lose power slowly and would not respond to engine control inputs. The pilot landed on a gravel bar and had to extinguish the fire in the engine accessory case with the fire extinguisher and dirt. The airplane has not been recovered and the engine has not been examined.
