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 attempting to land on an unlighted, gravel runway, at dusk, when he inadvertently touched down in a grass-covered drainage ditch, which was right of the gravel runway. During the landing roll, the airplane collided with a drainage culvert, sustaining substantial damage to the right wing and fuselage. The pilot noted in his written statement to the NTSB that he was unable to discern the difference between the gravel runway and grass-covered terrain due to the low-light conditions, and he mistakenly selected the grass-covered ditch. The pilot indicated that there were no mechanical anomalies with the airplane.
