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
WPR14CA006
The pilot reported that while in cruise flight, about 500 feet above ground level (agl), the cyclic control seemed to require a higher than normal input. He changed speed, however, that seemed to make it worse. The pilot was over a field and entered a 180 degree autorotation to lose altitude. At the completion of the autorotation, forward velocity had dissipated and the lateral movement to the left increased even with full right cyclic input. The helicopter collided with trees that bordered the field and subsequently rolled over onto its left side after touchdown. The fuselage and tailboom were substantially damaged.
NTSB Probable Cause
A flight control malfunction during cruise flight for reasons that could not be determined. No follow-up examination was conducted due to a lapse in agency funding and subsequent government shutdown.
