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 the purpose of the flight was to drop off crew members and pick up secured bundles of trash from a remote landing zone. He had landed at this landing zone several times throughout the day. After an uneventful landing, the helicopter started to shake abruptly. The pilot maintained control of the helicopter until the shaking stopped and he could shut down the engine. A witness reported that a tarp from a nearby trash bundle had flown up into the main rotor blades; subsequently, one of the main rotor blades departed the helicopter and sustained substantial damage. There were no mechanical failures or malfunctions with the airframe or engine that would have precluded normal operations.
