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
CEN20CA308
The pilot reported that he conducted a visual approach to land at a grass airstrip with tall crops adjacent to the runway. As he was landing a deer jumped out of the crops onto the runway. The pilot pulled the nose up to avoid hitting the deer and the airplane stalled. The airplane hit the ground and "flipped" two times, substantially damaging the tail, wings, and fuselage. The pilot reported no mechanical anomalies with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot's exceedance of the airplane's critical angle of attack while attempting to avoid a deer during landing, resulting in an aerodynamic stall.
