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, during a hover taxi for takeoff, about 3 ft above the ground, he thought that he saw a person at the corner of his driveway. He added that he stopped and that the helicopter drifted to the left. Subsequently, the main rotor blade impacted a tree, which resulted in substantial damage to the fuselage. The pilot reported no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
