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, during his second flight, following the installation of a new autopilot, he noticed on short final that the mixture was set too lean. He added that, "with a gloved hand," he pushed the mixture in to a richer setting and accidently turned on the autopilot, which was located directly above the mixture control. The autopilot was set to navigation mode, heading mode, and altitude mode from a previous flight. The pilot reported that he was "fighting the auto pilot" and that the airplane aerodynamically stalled, which resulted in a hard landing. The airplane sustained substantial damage to the firewall. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
NTSB Probable Cause
The pilot’s inadvertent application of the autopilot during short final, which resulted in an aerodynamic stall and hard landing.
