NTSB narrative
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.
Probable cause
INADEQUATE PREFLIGHT BY THE PILOT(S), WATER CONTAMINATION OF THE FUEL, LOW LEVEL OF DEICE FLUID (METHANOL) IN THE DEICE TANK, AND SUBSEQUENT ICE BLOCKAGE OF THE FUEL FILTERS. DARKNESS WAS A RELATED FACTOR.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1990-01-31.
