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 landed and taxied toward his hangar during night, visual meteorological conditions. As the pilot entered a general aviation parking ramp, the right main landing gear struck a parked helicopter dolly. The right gear collapsed, the right wing forward and aft spars were damaged, and a fuel leak resulted. The Federal Aviation Administration inspector and the airport authority reported that the parked dolly was clearly marked. The pilot reported that he did not see the dolly prior to the collision.
NTSB Probable Cause
The pilot's failure to see and avoid the marked helicopter dolly. Contributing to the accident were the dark night conditions.
