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 stated that he was flying the weight-shift control aircraft over a river while the passenger took photos. As he slowed and descended the aircraft near a bird's nest in order for the passenger to capture a photo, the aircraft entered an aerodynamic stall. The pilot applied full engine power to recover, but the aircraft continued to sink before impacting the river, resulting in substantial damage. The pilot and passenger subsequently egressed and swam to the shore. The pilot stated that there were no mechanical malfunctions or anomalies of the aircraft or engine that would have precluded normal operation of the airplane.
NTSB Probable Cause
The pilot's failure to maintain airspeed while maneuvering at low altitude, which resulted in an aerodynamic stall and impact with water.
