The NTSB's narrative final · quoted from the NTSB record
THE ACFT WAS EN ROUTE AT 31,000 FT, WHEN THE LOW PRESSURE FUEL FILTER WARNING LIGHT ILLUMINATED. THE PLT DIVERTED TOWARD COLUMBIA, MO, BUT BEFORE REACHING COLUMBIA, BOTH ENGINES LOST POWER. SUBSEQUENTLY, THE ACFT CRASHED ABOUT 2 MI EAST OF THE ARPT. AN INVESTIGATION REVEALED THE FUEL WAS CONTAMINATED WITH WATER. THE FUEL FILTER DEICING SYSTEM WAS OPERATIONAL, BUT A POST-ACDNT EXAM REVEALED THE DEICING TANK WAS EMPTY. THIS WAS THE 2ND FLT SINCE THE DEICE TANK HAD BEEN SERVICED. THE MANUFACTURER'S INFO INDICATED THE SUPPLY TANK SHOULD HAVE PROVIDED ABOUT 3 TO 4 HRS OF FILTER DEICING OPERATION.
