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 tailwheel-equipped biplane reported that she extended the downwind leg due to other aircraft in the traffic pattern and that, while on the extended final, she put the biplane in a "slip." During the slip, the windsock was out of view. She further reported that, during the landing flare, she noticed that the "ground-speed" was higher than normal and that "about 800 ft" after touchdown, the biplane "violently swerved to the right." She attempted to recover with rudder inputs; however, the biplane veered off the runway and came to rest inverted. The biplane sustained substantial damage to the empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
NTSB Probable Cause
The pilot’s failure to maintain directional control during the landing roll. Contributing to the accident was the pilot’s unstabilized approach.
