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 PLT STATED THAT WHILE PREPARATING FOR FLT, HE WAS STARTING THE ENG BY HAND PROPPING. THE ENG FLOODED, SO HE OPENED THE THROTTLE, TURNED THE FUEL VALVES & MAGNETOS 'OFF' & PROPPED THE ENG 10 TIMES TO PUMP FUEL FROM THE CYLINDERS. HE THEN RETURNED TO THE COCKPIT, TURNED ON THE MAGNETOS & VERIFIED THE FUEL VALVES WERE OFF, BUT FORGOT TO CLOSE THE THROTTLE BEFORE RESUMING THE PROCEDURE. ALSO, HE DID NOT TIE-DOWN THE ACFT OR CHOCK ITS WHEELS. WHEN HE COMMENCED HAND PROPPING, THE ENG STARTED & WENT TO A HIGH POWER SETTING. SUBSEQUENTLY, THE ACFT HIT SVRL OBJECTS (INCLUDING A UTILITY POLE) & WENT INTO ABOUT 3 FT OF WATER IN A LAKE, BEFORE THE ENG STOPPED.
NTSB Probable Cause
FAILURE OF THE PILOT TO PROPERLY TIE DOWN AND CHOCK THE AIRCRAFT AND/OR OBTAIN PROPER ASSISTANCE, AND HIS FAILURE TO PROPERLY SET THE THROTTLE, WHILE HAND PROPPING TO START THE ENGINE.
