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 stated that he was taking off from an off-airport site on a mountain ridge when an updraft lifted the right wing. The airplane entered an aerodynamic stall that the pilot was unable to recover from before the airplane impacted terrain. The airplane sustained substantial damage to the right wing and fuselage. The pilot reported that there were no preaccident mechanical anomalies with the airplane.

NTSB Probable Cause

The pilot's failure to maintain sufficient airspeed during the initial climb after takeoff, which resulted in an aerodynamic stall.
