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 while conducting agricultural spraying operations he first circled the field to be sprayed and noted a windmill at the south end of the field. He started to spray the field and when conducting a spray pass lined up with the windmill, he pulled up to clear the windmill, but encountered a “pocket of dead air” which resulted in the airplane hitting the windmill. The pilot returned to the airport and upon landing the airplane’s left main landing gear collapsed and the airplane went off the side of the runway. The airplane sustained substantial damage to its fuselage. The pilot reported that there were no mechanical malfunctions or failures of the airplane before the accident.
