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.

According to several witnesses, the airplane departed the runway, and at approximately 50 feet, appeared to hang in the air. The airplane "fell" out of the sky, impacting the tarmac, adjacent to the departure runway. According to the pilot, he was planning on a soft field takeoff procedure and had selected full flaps. The pilot did not recall anything unusual during the departure roll and did not report any mechanical anomalies. The right wing was bent up at midspan and crumpled. The fuselage, and firewall was wrinkled, the engine was crushed aft and the propeller was broken.
NTSB Probable Cause
the pilot's failure to maintain aircraft control during the departure, resulting in an inadvertent stall.
Full Narrative
