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 of the experimental, amateur-built airplane was departing from a turf runway. He reported that as he passed his normal rotation point on the runway, he rotated the airplane without verifying his airspeed, which resulted in the airplane becoming airborne prematurely. The airplane rotated, rolled to the left, impacted a light pole, and came to rest inverted. Substantial damage was sustained to both wings and the fuselage. The pilot reported that there were no mechanical failures or malfunctions of the airplane prior to the accident.
