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 flight made a forced landing following a loss of engine power. The pilot stated that about 7 minutes after takeoff while in cruise flight at 1,000 feet above ground level, the engine sputtered. He stated that he began a turn to return to the airport and as he turned about 90 degrees, the engine lost power completely. He said that he elected to land in a farm field and during the landing he struck trees at the approach end of the field. The pilot stated that he believed the engine failure was due to a blocked fuel vent on the main tank of the airplane. Subsequent examination of the airplane revealed no anomalies with regard to the airplane or its engine. The main fuel tank was found to be nearly full of fuel. The auxiliary fuel tank contained a small amount of fuel.

NTSB Probable Cause

The fuel starvation for an undetermined reason, and the unsuitable terrain encountered during the forced landing. The trees were a factor.
