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 initially reported that while he was taking off, the tail dropped and hit the ground. After a postaccident review of a security video that captured the accident, the pilot along with his flight instructor concluded that he input excessive left anti-torque pedal as he increased collective. A National Transportation Safety Board review of the same security video showed the helicopter as it rotated counterclockwise about its vertical axis. The fuselage pivoted about the right skid and the helicopter exceeded its critical roll angle, which resulted in dynamic rollover. The helicopter sustained substantial damage to the fuselage and tailboom. The pilot reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operations.
NTSB Probable Cause
The pilot’s improper anti-torque pedal inputs during takeoff, which resulted in a loss of helicopter control during takeoff and subsequent dynamic rollover.
