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.

NYC06CA125
The flight instructor was demonstrating air-taxi maneuvers to the student pilot in a Robinson R-22 helicopter. The instructor slowed the helicopter to about 10 knots ground speed in a descending turn, and oriented the helicopter such that it experienced a tailwind. As the helicopter "settled", the pilot attempted to arrest the descent, but could not, and leveled the helicopter prior to a hard landing. The landing gear subsequently collapsed, the helicopter rolled over, and the main rotor blades contacted the ground. The instructor reported that there were no deficiencies with the performance or handling characteristics of the helicopter.
NTSB Probable Cause
The flight instructor's inadvertent encounter with settling-with-power, which resulted in a hard landing, and subsequent roll-over. A factor in the accident was the tailwind.
