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 in the experimental amateur-built airplane, he was conducting a flight test. During the takeoff roll, he applied "too much aft stick," and the airplane entered an unintentional steep climb at a low airspeed. The airplane rolled left about 30°, he corrected to the right, and the airplane's nose dropped. The pilot further reported that he may have reduced the throttle and overcorrected to the right. The airplane stalled and impacted the ground. The airplane sustained substantial damage to the right wing. The pilot reported that this was his second flight in the accident airplane. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot’s excessive application of aft stick during takeoff, which resulted in an aerodynamic stall. Contributing to this accident was the pilot’s inexperience in the airplane.
