NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

Weather information obtained by the pilot prior to departure indicated low ceilings and visibility with mountain obscurement due to clouds, precipitation and fog. Occasional moderate turbulence with moderate rime or mixed icing was also forecast. Another pilot flying in the area at the time of the accident reported observing 'very black clouds' that had a 'roll to them and moving fast.' That pilot also reported that the clouds looked 'very violent,' and stated that before he turned around to find another route, he was experiencing light to moderate turbulence, but was not picking up any ice below the cloud base. Radar data indicates that after departure the flight headed in a westerly direction. The radar indicates that the airplane made a left turn approximately 180 degrees and was experiencing rapid increasing and decreasing altitude changes before the airplane descended rapidly and dropped from radar coverage. The wreckage was located in mountainous terrain. Evidence indicates that the airplane collided with the terrain in a steep nose down attitude.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

the pilot's failure to maintain control of the aircraft. Flight into adverse weather and turbulence were factors.
