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 flight instructor reported that, during an instructional flight with the student pilot at the flight controls, just prior to touchdown, the airplane started drifting left of center. The instructor told his student to go around, but the airplane had already reached the edge of the runway. When the instructor took control, the airplane had already exited the runway and came to rest on the adjacent dirt terrain, which resulted in substantial damage to the left wing. The flight instructor reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause
The student pilot’s failure to maintain directional control, and the flight instructor’s delayed remedial action.
