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 aircraft collided with the runway and drug the right wing tip during a landing attempt. The aircraft then ground looped to the right off the runway. The pilot stated that the airplane had insufficient power to compensate for an increased sink rate on short final. A witness on the ground saw the wings rocking from side to side when the aircraft was at an altitude of approximately 40 feet, followed by a sudden veer to the left and an increase in sink rate prior to impact with the ground. The passenger, who was not a pilot, reported that 'we were crabbing and I thought he [the pilot] was pulling out' just prior to the ground collision.

NTSB Probable Cause

The pilot's failure to maintain an adequate airspeed while attempting a right slip, which resulted in an inadvertent stall.
