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 amphibious airplane was performing numerous touch-and-go water landings to a lake. During the last landing, to the south, the airplane touched down with the nose a "little bit" to the right, the left sponson then hit the water, and the airplane water looped. Several minutes later, the airplane sank to the bottom of the lake. The airplane incurred substantial damage to both wings and the fuselage. The pilot reported that there were no mechanical malfunctions or failures of the airplane prior to the accident. A weather observation taken about the time of the accident, and approximately 25 miles north of the accident site, included winds from 180 degrees true at 8 knots.
