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 helicopter pilot stated that he was performing a landing to a field by his workshop and was fast during the final approach. He landed hard to avoid overshooting his landing and hitting nearby power lines. The left skid dug in and the helicopter rolled over. Examination of the helicopter revealed that all three main blades were damaged, the tail rotor blades were damaged, and the tail boom was bent.
NTSB Probable Cause
The pilot's failure to maintain proper airspeed and descent rate during approach, which resulted in a hard landing. Contributing to the accident were the nearby power lines.
