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 GROUND LOADER HAD FUELED THE AIRPLANE FROM THE AIRPORT FUEL TRUCK. HE STATED THAT THE FLIGHT CREW DID NOT SUMP THE FUEL TANKS AFTER THEY WERE FUELED. IMMEDIATELY AFTER TAKEOFF THE RIGHT ENGINE LOST POWER, THE RIGHT WING LOWERED TO ABOUT 90 DEG, AND THE AIRPLANE IMPACTED THE GROUND ADJACENT TO THE RUNWAY. THEN FORWARD FUEL TANK, WHICH PROVIDES FUEL TO THE RIGHT ENGINE, WAS FOUND TO CONTAIN ABOUT 8 GALS OF A HEAVILY CONTAMINATED MIXTURE COMPOSED OF WATER, AN EMULSIFYING AGENT, AND BACTERIAL GROWTH. THE FUEL FROM THE AIRPORT FUEL TRUCK AND MAIN UNDERGROUND TANK CONTAINED THE SAME MIXTURE. FUEL HAD BEEN TRANSFERED FROM THE UNDERGROUND TANK TO THE TRUCK ON THE EVENING PRECEDING THE ACCIDENT. THE LEFT PROPELLER CONTROL WAS FOUND SEIZED IN THE FEATHER POSITION; LEFT PROPELLER BLADES IN THE NEAR-FEATHER POSITION.
NTSB Probable Cause
THE PILOT-IN-COMMAND'S INADVERTENT FEATHERING OF THE WRONG PROPELLER FOLLOWING AN ENGINE POWER LOSS, AND THE FAILURE OF THE OPERATOR TO ASSURE THAT THE PILOT WAS PROVIDED WITH ADEQUATE TRAINING IN THE AIRPLANE. FACTORS RELATED TO THE ACCIDENT WERE: WATER CONTAMINATION OF FUEL IN THE AIRPORT STORAGE TANKS, THE OPERATOR'S LACK OF FUEL QUALITY CONTROL PROCEDURES, IMPROPER FUEL SERVICING, IMPROPER PREFLIGHT BY THE PILOT(S), AND EXCEEDING THE GROSS WEIGHT/FORWARD CG LIMITS OF THE AIRPLANE.
