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 in the helicopter reported that the student pilot was practicing autorotations from a hover while pointing the helicopter into the wind over tall grass from about 1 ft above the ground. He added that the student "rolled off the throttle, the helicopter descended to the ground, appeared to bounce, moved slightly to the right and began a quick roll to the right." Subsequently, the helicopter pivoted on its right skid, the main rotor impacted terrain, and the helicopter rolled over to the right. The main rotor and windscreen sustained substantial damage. The flight instructor reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
NTSB Probable Cause
The student pilot's loss of lateral control while practicing autorotations from a hover and the flight instructor's delayed remedial action, which resulted in a bounced landing and dynamic roll-over.
