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.

WPR09CA289

The commercial pilot was practicing touch-and-go landings in the tail wheel equipped airplane. He reported that the wind direction changed to a quartering tailwind after the airplane touched down. The pilot stated that he then lost directional control of the airplane and did not believe he had sufficient engine power to recover. During the accident sequence the left main landing gear failed and the airplane ground looped, resulting in substantial damage to the left wing and horizontal stabilizer. The pilot stated that the airplane and engine had no mechanical failures or malfunctions prior to the accident.

NTSB Probable Cause

The pilot's inadequate compensation for the wind conditions and failure to maintain directional control during the landing roll.
