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 reported that he descended to make a low pass over Pettit Lake. He noted that the clear weather condition with no wind impacted his depth perception as the lake surface appeared glassy. During the low pass over the water, the pilot misjudged his altitude above the lake, and the airplanes main landing gear contacted the water. The airplane then bounced and impacted the water a second time before it came to rest and sank. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that could have precluded normal operation. The airplane was not recovered.
