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 HELICOPTER WAS FLOWN TO THE SITE OF AN AUTO ACCIDENT TO TRANSPORT AN INJURED PERSON. AFTER LANDING, THE PATIENT WAS LOADED WITHOUT SHUTTING DOWN THE ENG. DUE TO THE POSITION OF POWER LINES, THE AIRCREW HAD TO DEPART IN THE OPPOSITE DIRECTION. WHILE PREPARING TO DEPART, THE PLT BROUGHT THE HELICOPTER TO A HOVER & BEGAN A PEDAL TURN. AS THE ACFT WAS TURNING, AN AMBULANCE DRIVER BEGAN BACKING HIS VEHICLE TOWARD THE HELICOPTER. THE PLT INSTINCTIVELY PULLED AFT ON THE CYCLIC. THIS RESULTED IN THE TAIL ROTOR CONTACTING A LOW ROAD BARRIER POST. THERE WAS A LOSS OF TAIL ROTOR EFFECTIVENESS, SO THE PLT RETARDED THE THROTTLE TO THE OFF POSITION & MADE A HOVER AUTOROTATION.
