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, after about 30 minutes of flight, he advanced the throttle and the engine went to idle power then stopped. He restarted the engine and determined that it would only operate at idle power before it stopped again. He was flying over rocky terrain and determined that the best option was to ditch the airplane in a nearby river. After ditching the airplane in the river, the pilot swam to shore. The airplane sank and will not be recovered.
NTSB Probable Cause
A partial loss of engine power during cruise flight for reasons that could not be determined because the airplane was not recovered.
