What happened
While cruising at 31,000 feet, the pilot of the aircraft observed the illumination of the low pressure fuel filter warning light. In response to the warning, the pilot initiated a diversion toward Columbia, Missouri. However, before the aircraft could reach the airport, both engines lost power. The aircraft subsequently crashed approximately 2 miles east of the airport.
The investigation
An investigation into the accident revealed that the fuel used in the engines was contaminated with water. While the fuel filter deicing system was found to be operational, a post-accident examination determined that the deicing tank was empty. This flight was only the second operation conducted since the deice tank had been serviced. According to manufacturer information, the supply tank should have provided approximately 3 to 4 hours of fuel filter deicing operation.
