Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

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.
NTSB 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.
