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
CEN11CA609
The pilot reported that, while on a cross-country flight, the fuel in the left tank was exhausted and the engine stopped producing power. The pilot attempted to restore fuel to the engine by switching to the right tank, which contained fuel; however, realizing that he was too low to attempt an engine restart, he elected to perform a gear-up landing to a field. The airplane’s fuselage and right wing sustained substantial damage during the landing. No other preimpact anomalies with the airplane were reported.
NTSB Probable Cause
A total loss of engine power in flight due to fuel starvation as a result of the pilot’s inadequate fuel management.
