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 reported that, after multiple attempts to find a suitable landing site on a mountain ridgetop, the tail rotor impacted brush during landing. The helicopter pivoted, the main rotor contacted a communications tower, and the helicopter then rotated 180° and rolled onto its left side. The helicopter sustained substantial damage to the windscreen and main rotor mast. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
NTSB Probable Cause
The pilot’s selection of unsuitable terrain for landing, which resulted in impact with brush and a loss of helicopter control.
