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.

The airplane ground looped during takeoff. The pilot reported that he had been doing full stop landings. On his sixth takeoff the plane veered slightly left due to P-factor. He corrected with right rudder. His rudder application had minimal effect, so he added more right rudder, which caused the plane to ground loop to the right. The ground loop substantially damaged the right wing. The pilot stated that the airplane and engine had no mechanical failures or malfunctions during the flight.
NTSB Probable Cause
The pilot's failure to maintain directional control during takeoff.
