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
WPR14CA090
The pilot stated that he had completed four landings, and while at a fast taxi he touched both toe brakes. The airplane began a gradual turn to the right. He corrected the right turn first with left rudder control then left brake, however, neither action corrected the tightening right-hand turn. When the airplane encountered the edge of the runway, it nosed down and tilted to the left, substantially damaging the left wing. The pilot described the right brake as "dragging" throughout the accident sequence.
NTSB Probable Cause
The pilot did not maintain directional control during the landing roll out when the right brake did not release completely after he applied, then released brake pressure, which resulted in a ground loop. Contributing to the accident was the taxi speed.
