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 airplane experienced a loss of engine power and nosed over in a field during the forced landing. The pilot reported that after flying for about 40 minutes he noticed the oil temperature gauge begin to rise. He had started looking for a suitable place to land when the oil temperature and engine temperature gauges both went beyond the red line. At 2,500 feet the engine made loud metallic clanking noises and began to shake violently. He shut the engine down and proceeded to make an emergency landing in a plowed field. The airplane nosed over during the ground roll. Examination of the antique Ford Model B engine revealed that the connecting rod for the number 2 piston failed. The time since last overhaul on the engine was 6 hours.
