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, after takeoff for the aerial application flight, he made a standard turn to line up with the field to be sprayed and began to descend to fly under two sets of powerlines. He then observed a telephone pole to the right and thought he had plenty of clearance to avoid it. He then heard and felt the impact of a main rotor blade strike the pole. The helicopter yawed to the right before it impacted the ground, rolled forward, and came to rest on its left side. The helicopter was destroyed. The pilot reported no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
