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 flight instructor reported that, while conducting hover autorotation training from about one foot above the ground, the pilot receiving instruction quickly closed the throttle. The helicopter subsequently descended rapidly, caught the left skid on the pavement and rolled over to the left. The helicopter sustained substantial damage to the tail boom and main rotor blades. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
NTSB Probable Cause
The pilot receiving instruction’s rapid reduction in throttle during hover autorotation training which resulted in a loss of control and collision with the ground.
