What happened
The flight crew passed over Kunming Airport and proceeded southeast along their intended route. Approximately ten minutes later, the aircraft experienced a complete loss of fuel. The captain instructed the remaining crew members to abandon the airframe. All four individuals on board ejected from the plane successfully. Following their departure, the unmanned aircraft descended and impacted the ground in a grassy area.
Findings
Investigations indicated that the decision to eject was necessitated by the depletion of fuel reserves. The official report confirmed that the crew's action to leave the aircraft was taken specifically because they had run out of fuel. All four occupants were reported as uninjured following the crash.
