What happened
The pilot attempted to operate an aircraft without proper authorization. Shortly after initiating the takeoff phase, the engine ceased functioning. Due to this mechanical failure, the pilot was compelled to execute an emergency landing in a soft field adjacent to the departure area.
The investigation
Post-accident examination of the aircraft revealed critical fuel system discrepancies. Three of the four fuel tanks were discovered to be either completely empty or containing only amounts below the unusable fuel threshold. Additionally, the fuel selector valve was found positioned in the 'off' setting, preventing any potential fuel flow to the engine.
Findings
The primary factors contributing to this incident included the operation of the aircraft by an individual lacking the necessary authorization. The mechanical failure was directly linked to fuel exhaustion caused by the empty tanks and the mispositioned selector valve.
