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 he was practicing hover flight in a helicopter over soft grass at a height of 5 to 7 feet above the ground with a student pilot on his second training flight. The flight instructor further reported that he was controlling the collective and anti-torque pedals, and the student pilot was controlling the cyclic control. During the hover, the flight instructor reported that he became fixated on the manifold pressure gauge and did not notice that the helicopter was moving forward and descending. Subsequently, the helicopter's right skid impacted the ground and rolled over. The main rotor drive shaft and tailboom were substantially damaged. The flight instructor did not report any mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
NTSB Probable Cause
The flight instructor's failure to monitor outside the helicopter during hover flight, which resulted in a collision with terrain and rollover.
