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.

AFTER ABOUT 1 HOUR AND THIRTY MINUTES OF FLIGHT, A TOTAL LOSS OF POWER OCCURRED IN THE LEFT ENGINE. WHILE THE PILOT WAS DIAGNOSING THE PROBLEM, THE RIGHT ENGINE LOST POWER. THE PILOT DID NOT SWITCH THE FUEL TANK SELECTORS TO THE OUTBOARD TANKS, AND EXECUTED AN EMERGENCY LANDING ON THE DESERT TERRAIN. DURING THE LANDING ROLL, THE AIRPLANE COLLIDED WITH A FENCE AND NOSED OVER. AN EXAMINATION DISCLOSED THAT THE OUTBOARD FUEL TANKS CONTAINED FUEL; THE INBOARD FUEL TANKS WERE EMPTY.
NTSB Probable Cause
FUEL STARVATION DUE TO THE IMPROPER FUEL MANAGEMENT (POSITIONING OF THE FUEL SELECTOR) BY THE PILOT, AND HIS IMPROPER EMERGENCY PROCEDURES. THE PILOT'S LACK OF EXPERIENCE IN THIS MAKE AND MODEL OF AIRCRAFT WAS A RELATED FACTOR.
