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, during the agricultural application flight into rising terrain, he saw power wires. He said he "lowered the collective…slightly nose down" to attempt to go under the wires, but the helicopter struck the wires, rolled right, and started descending. The helicopter touched down, bounced, spun right, and then rolled onto its left side. The helicopter sustained substantial damage to the tail rotor drive system. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
