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.

WPR12CA162
The pilot stated that, while he was landing downwind, the helicopter began to yaw to the right. The pilot applied left pedal and forward cyclic inputs in an attempt to correct the yaw; however, the helicopter continued to rotate and descend. Shortly thereafter, the helicopter touched down on both skids and rolled onto its right side, which resulted in substantial damage to the airframe and rotor blades. The pilot reported no mechanical anomalies that would have precluded normal operation.
NTSB Probable Cause
The pilot did not maintain directional and yaw control of the helicopter during approach and landing, which resulted in a dynamic rollover.
