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
ANC12CA070
The pilot stated that during cruise flight, the engine suddenly lost all power. He attempted to restart the engine but was unable and elected to make a forced landing in a bog. During the landing, the left wing and right elevator stuck trees, sustaining substantial damage. After the forced landing, the pilot noticed that the emergency fuel shutoff lever on the right side of the center console had been moved toward the shutoff position. The passenger who was seated in the right seat of the cockpit stated that he was unaware of the fuel shutoff lever and was not briefed on specific areas to be aware of in the cockpit but that he had been adjusting himself in the seat just prior to the engine shutting down.
NTSB Probable Cause
The right seat passenger’s inadvertent contact with the emergency fuel shutoff valve, which resulted in fuel starvation and a total loss of engine power. Contributing to the accident was the pilot's failure to provide a thorough preflight briefing to the passenger seated in the cockpit.
