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 reported that while in cruise flight the engine RPM of the helicopter suddenly increased to the point where the rev limiter activated. At this point the helicopter was about 700 ft above ground level and the pilot performed an autorotation to a baseball field. During the forced landing, the helicopter sustained substantial damage to its fuselage. Subsequent examination of the helicopter revealed that the main drive belt that transmitted engine power to the rotor system had failed.

NTSB Probable Cause

The failure of the helicopter's main drive belt resulting in the pilot performing a forced landing, during which the helicopter's fuselage was substantially damage.
