Move quickly by aircraft, airport, operator, and time with indexes built for research, not wandering.
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.
Yuba City, CA
The pilot in the helicopter reported that, during cruise flight at dusk with night vision goggles on, he encountered a flock of birds at 1,500 ft above ground level. As the pilot initiated a climbing left turn to avoid the birds, he heard a loud bang accompanied by a pain in his left leg. The helicopter then began to vibrate, and the pilot initiated a precautionary landing in a nearby field without further incident. Bird remains were located throughout the pilot side of the cockpit. The helicopter sustained substantial damage to the windshield. The pilot reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
