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 pilot reported that, following a “smooth” landing, he reduced power, but the throttle control broke and the engine advanced to full power. The pilot immediately placed the mixture control in the lean position, but the airplane overran the runway onto a road. The left wing of the airplane subsequently contacted a fence, the airplane rotated left 180° and impacted a fencepost before it came to rest. The right main landing gear collapsed, and the airplane sustained substantial damage to the wings.
NTSB Probable Cause
A failure of the throttle control during a landing roll, which resulted in a loss of control and collision with a fence.
