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 stated that he was approaching a landing zone on a flat pinnacle with a tailwind. The helicopter was within 50 feet of the landing area in a slow, stable, shallow approach when it encountered an updraft. When the helicopter flew out of the updraft, it abruptly descended to the ground. The helicopter landed hard, and the impact buckled the tail boom and sheared off the left landing gear skid.
NTSB Probable Cause
The pilot's inadequate compensation for wind conditions during landing, which resulted in a hard landing.
