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 student pilot stated they had been practicing hovering for about 30 minutes, and were about two feet above the ground. He recalled that he was "controlling the cyclic and maybe the collective, but not the pedals." The flight instructor thought they were three to five feet above the ground. The helicopter experienced a pendular motion and began traveling backwards and to the right. The right skid made contact with the ground, which resulted in the tail impacting the ground and the helicopter rolling onto its side. The helicopter sustained substantial damage to the tail rotor.
