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 wanted to take some photographs of a building on his farm. It was a "hot (85 to 88 degrees) humid day." He made one pass to the north before turning around to the south. On the second pass at reduced power, the airplane began to settle towards the ground from about 200 feet. He added power but the airplane's wheels contacted wheat on rising terrain. From 95 KIAS (knots indicated airspeed), the "drag was instant." Despite full power and full back elevator, the airplane struck the top of an incline, the nose gear collapsed, and the airplane nosed over.
