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 helicopter sustained substantial damage during a dynamic roll over on takeoff. The pilot made a precautionary landing, in a cornfield, in response to a warning light.

The left skid had sunk into the ground further than it appeared." The pilot reported no mechanical malfunctions with the helicopter. The pilot's safety recommendation stated, "I could have made a ... more [thorough] check of ground conditions before attempting a takeoff."
NTSB Probable Cause
The pilot's improper use of the rotorcraft flight controls resulting in a dynamic rollover during takeoff. A factor was the soft ground that the left skid encountered.
