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 CFI AND DUAL STUDENT WERE ON INITIAL TAKEOFF AFTER THE STUDENT HAD SUCCESSFULLY HANDLED A SIMULATED RIGHT ENGINE FAILURE ON TAKEOFF ROLL. SHORTLY AFTER TAKEOFF, THE LEFT ENGINE QUIT. THE CFI TOOK CONTROL, BUT WAS UNABLE TO CLEAR TREES OFF THE END OF THE RUNWAY. THE AIRPLANE COLLIDED WITH THE TREES BEFORE IMPACTING THE GROUND. AN INSPECTION OF THE AIRCRAFT FUEL SYSTEM REVEALED PRESENCE OF SOME SILICONE-TYPE MATERIAL IN THE LEFT FUEL TANK. THIS MATERIAL STOPPED UP A HAND PUMP USED TO EMPTY THE FUEL TANK AT THE ACCIDENT SITE. AFTER THE ACCIDENT, THE LEFT ENGINE WAS SUCCESSFULLY RUN WITH AN ALTERNATE FUEL SYSTEM, AND NO ABNORMALITIES WERE FOUND.
NTSB Probable Cause
THE INTERRUPTION OF FUEL TO THE LEFT ENGINE DUE TO CONTAMINATION OF THE LEFT FUEL TANK, RESULTING IN ENGINE STOPPAGE.
