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.

ERA09CA525
The certificated flight instructor and his student were on approach, in a glider. The student was attempting to make a no-airbrake landing. While on approach, the student was using a forward slip to correct the altitude. The instructor reported that his student’s aggressive control inputs made the aircraft too slow and too low to reach the airfield. The instructor took over the controls and decided to make an off-field landing. While landing, the glider’s right wing impacted tall grass. The flight instructor reported that the aircraft ground looped to the right causing substantial damage to the rudder and empennage. Neither the flight instructor nor the student reported any mechanical failures or malfunctions of the airplane.
