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 a cross-country flight over mountainous terrain, he had a tailwind and allowed the airplane to get too close to terrain. He initiated a right turn to avoid rising terrain, but the terrain was "getting close very quickly." The pilot increased the bank angle, and the nose dropped. The pilot then applied forward pressure on the yoke, and full throttle had already been applied. The airplane stalled and then impacted terrain. Both wings and the fuselage sustained substantial damage. In the recommendation section of the National Transportation Safety Board Pilot Aviation Accident Report, the pilot reported that his decision to delay the turn away from rising terrain was impulsive and the main reason for this accident. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.

NTSB Probable Cause

The pilot’s exceedance of the airplane’s critical angle of attack during a turn away from terrain, which resulted in an accelerated stall. Contributing to the accident was the pilot’s decision to delay the turn to avoid terrain.

Full Narrative

The pilot reported that during a cross-country flight over mountainous terrain, he had a tailwind and allowed the airplane to get too close to the terrain. He initiated a right turn to avoid the rising terrain, but the terrain was "getting close very quickly." The pilot increased bank angle and the nose dropped. The pilot then applied forward pressure on the yoke, and full throttle had already been applied. The airplane descended and impacted terrain. Both wings and the fuselage sustained substantial damage. Per the National Transportation Safety Board Pilot Aviation Accident Report, the pilot reported in the Recommendation section that his decision to delay the turn away from rising terrain was impulsive and the main culprit for this accident. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
