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.

According to the pilot of the amateur built Fred S1 airplane, during takeoff roll and just as the main wheels left the runway, the airplane turned sharply right. He applied full left "stick" and got the wings level, but by then he was at a right angle to the runway with a good stretch of grass ahead, so he landed. The pilot stated that unfortunately the grass was swampy and the airplane nosed over onto it's back. The pilot exited from the open cockpit with no problem. The pilot further stated that there were no mechanical malfunctions noted with the airplane prior to the accident. Examination of the airplane by an Federal Aviation Administration (FAA) inspector found the vertical stabilizer crushed and partially separated from the airframe.
