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.

During an instructional flight in crosswind conditions, the pilot receiving instruction initiated the takeoff roll and once the airplane became airborne, the nose immediately rotated into the wind. The flight instructor took the flight controls and attempted to maintain directional control with right rudder, but the airplane touched down on the runway and ground looped. During the ground loop the right wing impacted the runway causing substantial damage to the wing. The flight instructor reported no mechanical malfunctions or failures with the airplane that would have precluded normal operation. The reported winds about the time of the accident were from 110 degrees true at 12 knots, and the runway heading was 180 degrees magnetic.
