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
WPR23LA074
The pilot reported that, during the takeoff, the fuel tank selector was mistakenly set to the auxiliary tank. Five minutes later the auxiliary tank ran out of gas, which resulted in a total loss of engine power. The pilot switched to the main tank; however, there was insufficient altitude available for a recovery. The airplane struck terrain about 100 ft short of the runway, which substantially damaged the left and right wings. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot’s fuel mismanagement which resulted in fuel starvation and a total loss of engine power.
