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.

GAA18CA192
The flight instructor reported that, during a training flight, upon landing, the tailwheel-equipped airplane bounced slightly. Subsequently, when the airplane touched back down, it veered to the left. He added that the student did not react immediately, so he added power and right rudder to correct. The airplane exited the left side of the runway, the instructor added full right brake to avoid a visual approach slope indicator (VASI) light, and the airplane ground looped to the right. The flight instructor added that the student had apparently touched down after the first bounce with the left brake engaged. The airplane sustained substantial damage to the left wing and aileron. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
NTSB Probable Cause
The student pilot’s failure to maintain directional control during landing after touching down with the left brake engaged. Contributing to the accident was the flight instructor’s delayed remedial action.
