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.

NTSB Number
GAA19CA163
The pilot of the tailwheel-equipped airplane reported that, during the landing roll, the tail "lifted back up" due to a "wind gust" and that the airplane then veered left, spun, exited the runway, and the right wing impacted muddy terrain. The airplane sustained substantial damage to the right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot reported the wind was light and variable at 5 knots. An automated weather observation station located about 15 nautical miles from the accident site reported that, about 30 minutes before the accident, the wind was from 150° at 4 knots and that, about 30 minutes after the accident, the wind was from 120° at 5 knots. The pilot landed the airplane on runway 30.
NTSB Probable Cause
The pilot's failure to maintain directional control during landing in variable wind conditions, which resulted in the right wing impacting muddy terrain.
