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.
Watertown, SD
Witnesses stated the airplane made a steep turn at low altitude, followed by a rapid descent and ground impact. The uncertificated pilot was seriously injured and did not recall any of the accident sequence, due to head trauma. Examination of the airframe and engine by Federal Aviation Administration personnel revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation.
