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 skid-equipped helicopter reported that the purpose of the flight was to conduct an aircraft transition flight. The pilot under instruction performed a touchdown autorotation on the asphalt runway. The helicopter touched down in a level attitude just right of the centerline and then slid on its skids off the right side of the runway into grass. The helicopter spun right and rolled onto its left side. The helicopter sustained substantial damage to the main and tail rotor drive systems. Both pilots reported that there were no mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
NTSB Probable Cause
The pilot under instruction's failure to maintain directional control and the flight instructor's delayed remedial action.
