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 pilot stated that before lifting off from the refueling pad, he maneuvered the helicopter where the skids were still on the ground, but lightly touching and not supporting its entire weight. The helicopter made a slight yaw to the left which accelerated into a rapid spin to the left that he could not correct with right pedal input. In an attempt to arrest the spin, the pilot closed the throttle, lowered the collective, and closed the mixture control. On the fourth rotation, the tailboom struck a pole-mounted fire extinguisher, and the helicopter came to rest upright. The pilot reported that there were no mechanical deficiencies with the helicopter. He further stated that his heavy coat and boots worn to combat the unseasonably cold weather may have interfered with the flight controls.

Full Narrative
The pilot stated that he completed the before takeoff checks and got the helicopter "light on the skids" before lifting off from the refueling pad. A slight yaw to the left became a rapid spin to the left that could not be corrected with right-pedal input. The pilot closed the throttle, lowered collective, and closed the mixture control to arrest the spin. On the fourth rotation, the tail struck a pole-mounted fire extinguisher, and the helicopter came to rest upright. The pilot reported that there were no mechanical deficiencies with the helicopter, and stated that his heavy coat and boots worn to combat the unseasonably cold weather may have interfered with the flight controls.
