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.

CHI08CA203
The pilot stated that the helicopter had undergone an annual inspection at the helicopter manufacturer, and he was returning when he felt a "sudden" yaw to the left during cruise flight about 32 miles from the destination airport. The pilot then performed an "immediate" descent to a clearing, and about 60 feet above ground level and 30 miles per hour, the engine lost power. The helicopter landed on its skids and spun 180 degrees, impacting a tree with its tail rotor. The tail boom separated from the fuselage and a fire ensued consuming about 10 acres of land. The pilot exited the helicopter through the "partially jammed" passenger door because the pilot door was "jammed." The pilot received minor injuries. Examination of the engine revealed a cylinder head that was separated from its barrel.
NTSB Probable Cause
The unsuitable terrain encountered by the pilot during a forced landing following a loss of engine power due to a cylinder head separation. Contributing to the accident was the tree.
