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 of the experimental helicopter reported that, he had performed maintenance on the tail rotor assembly. While checking the blade tracking and balance in a hover, a pitch change link retention bolt lost torque and separated from the tail rotor slide assembly, which resulted in the loss of control and subsequent rollover. The helicopter sustained substantial damage to the fuselage, tailboom, and main rotor system. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter and that he failed to ensure the maintenance was performed correctly.
NTSB Probable Cause
The pilot’s improper maintenance on the tail rotor assembly, which resulted in the loss of control and roll over.
