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 reported that he began a right orbit off the shore of an island about 20 ft above the water. During the maneuver, the helicopter drifted and struck a tree leaning over the water. The helicopter subsequently lost altitude, impacted the water, and came to rest on its right side. The helicopter sustained substantial damage to the main rotor blades and fuselage. The pilot reported that there were no preaccident malfunctions or failures with the helicopter that would have precluded normal operation.
