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 the pilot, about 150 ft above ground level, the airplane encountered an unexpected windshear which resulted in a “significant sink rate” and loss of about 10 knots of airspeed. The pilot attempted to arrest the descent by adding engine power but was unsuccessful. The airplane landed hard, bounced, and then settled on the runway. Postaccident examination of the airplane revealed substantial damage to the firewall. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot’s failure to maintain airplane control during final approach after encountering an unexpected windshear.
