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 was substantially damaged after attempting to abort a landing following a ground loop on runway 27 (4,000 feet by 75 feet, asphalt). The pilot stated that the landing was good, but when he reached to turn off the carb heat the airplane turned to the left. He over-controlled with right rudder and attempted to abort the landing by adding power. He became airborne, stalled, and clipped a tree, causing the airplane to impact terrain.
NTSB Probable Cause
The pilot's failure to maintain directional control during the landing roll and failure to maintain sufficient airspeed during the aborted landing attempt, leading to an inadvertent stall. An additional factor was the tree.
