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 PILOT REPORTED THAT HE PREFLIGHTED THE FLOAT PLANE, PUMPED THE FLOATS, AND CHECKED FOR WATER. AFTER THE ENGINE START, TAXI, AND PRETAKEOFF CHECKS, HE SET THE FLAPS AT THE FIRST NOTCH. HE ABORTED HIS FIRST TAKEOFF RUN AND TAXIED BACK FOR A LONGER RUN. THE PILOT STATED THAT THE ENGINE WAS PRODUCING NORMAL POWER, BUT THE AIRCRAFT STILL TOOK LONGER THAN NORMAL TO REACH FLYING SPEED. AT 55 MPH, THE PILOT SET A SECOND NOTCH OF FLAPS AND THE AIRCRAFT LIFTED OUT OF THE WATER. HOWEVER, THE PILOT REPORTED THE AIRSPEED WAS DECREASING, SO HE LOWERED THE NOSE SLIGHTLY, BUT THE SPEED CONTINUED TO DECREASE. SUBSEQUENTLY, THE PLANE SETTLED INTO TREES NEAR THE END OF THE LAKE. THE AIRCRAFT WAS ESTIMATED TO BE 21 LBS OVER ITS MAXIMUM GROSS WEIGHT LIMIT. THE ELEVATION OF THE LAKE WAS ABOUT 300 FT, BUT THE DENSITY ALTITUDE WAS ABOUT 688 FT. THE WATER ON THE LAKE WAS REPORTED TO BE CALM.
