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 had just begun crop dusting when a gust of wind forced him into the ground from a height of approximately one hundred and fifty feet. The airplane struck the ground in a left-wing-low and nose-down attitude. The left side of the aircraft impacted a tree, resulting in substantial damage. The pilot said that he was aware of a nearby thunderstorm but did not believe it would affect his flight. Upon exiting the aircraft the pilot estimated the wind to be approximately thirty miles per hour. It began to rain twenty minutes after the accident. No preflight briefing was received. The pilot reported no mechanical anomalies prior to the accident.
NTSB Probable Cause
The pilot's failure to maintain aircraft control in flight. Contributing to the accident was his decision to fly with known hazardous weather conditions in the vicinity.
