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 of the float-equipped airplane reported that while accelerating on the water for takeoff, he impacted a green channel buoy and nosed over, which resulted in substantial damage to the left wing, left lift strut and fuselage. The pilot reported that there were no preaccident mechanical malfunctions or anomalies with the airplane that would have precluded normal operation, and that the accident may have been prevented if he had taxied clear of the obstructions before initiating his takeoff.
