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
GAA19CA313
The flight instructor in the tailwheel-equipped airplane reported that, after landing, the airplane veered left. In an attempt to correct back to centerline, the pilot receiving instruction applied full right rudder. The instructor immediately applied full left rudder and brake to prevent a ground-loop, but the airplane ground looped to the right, the left main landing gear collapsed, and the left wing impacted the ground. The airplane sustained substantial damage to the left wing. The instructor reported that a Federal Aviation Administration inspector examined the airplane's systems and found no anomalies. The airport's automated weather observation station reported that, about the time of the accident, the wind was variable at 3 knots. The pilot landed the airplane on runway 34.
NTSB Probable Cause
The pilot receiving instruction's failure to maintain directional control and his overapplication of right rudder and the flight instructor's delayed remedial action during the landing, which resulted in a ground-loop.
