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 was departing from a gravel bar when the accident occurred. He stated that prior to the takeoff he examined the gravel bar for the firmest ground for the takeoff roll. After the tail came up during the takeoff roll, the pilot realized that he was not aligned along his intended takeoff path. The pilot was not able to abort the takeoff roll and rolled from the gravel bar to the water. The airplane came to rest in the water inverted, resulting in substantial damage to both wings and the empennage. The pilot verified that there were no mechanical anomalies with the airplane prior to the accident.
NTSB Probable Cause
The pilot's selection of unsuitable terrain for takeoff and inability to abort the takeoff, resulting in an overrun into the water.
Full Narrative

After the tail came up, during the takeoff roll, the pilot realized that he was not aligned along his intended takeoff path. The pilot was not able to abort the takeoff roll and rolled from the gravel bar to the water. The airplane came to rest in the water inverted resulting in substantial damage to both wings and the empennage. The pilot verified that there were no mechanical anomalies with the airplane prior to the accident.
