The U.S. Air Force investigation into an October 2025 crash of a Block-1 OA-1K “Skyraider II” concludes that pilot error led to the aircraft losing usable fuel supply. According to reporting from Military Times and Air Force Times, a student pilot reached for the wrong fuel control inside the aircraft. That action shuts off the fuel supply, resulting in the student pilot being forced to crash-land the Skyraider II. Both outlets describe the event as a mishandling of fuel controls during the flight, rather than a mechanical failure. The investigation findings, as summarized in both sources, attribute the cause to incorrect selection or operation of the fuel control by the student pilot. The incident involved a crash-landing rather than a normal landing, consistent with the reported loss of fuel supply after the control was inadvertently shut off.
