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.

NTSB Number
NYC06CA173
As the helicopter climbed to about 15-20 feet during a hover, the pilot felt that "something was pushing the helicopter." Shortly thereafter, the helicopter began to descend and the rotor RPM began to decrease. The pilot initiated a precautionary landing, during which the passenger inadvertently pushed on the rudder pedals. The pilot was unable to maintain directional control, and the helicopter rolled onto its side as it touched down.
NTSB Probable Cause
The passenger's inadvertent interference with the flight controls, which resulted in a loss of directional control and subsequent impact with the ground.
