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 tailwheel landing gear-equipped airplane, he took off from grassy, wet, down sloping terrain. He recalled that he walked the area of intended takeoff and found no obstacles that would prevented a safe takeoff. However, he reported that during the takeoff roll, he kept the airplane tailwheel off of the ground, while rolling down slope, and the airplane main landing gear wheels rolled over a patch of mud creating a pivot point, and the airplane nosed over. The airplane sustained substantial damage to the vertical stabilizer, rudder, and wing struts. The pilot reported that there were not any mechanical malfunctions or anomalies with any portion of the airplane, prior to the takeoff roll that would have precluded normal flight operations.

NTSB Probable Cause

The pilot's selection of an unsuitable takeoff area resulting in an airplane nose over during the takeoff roll.
