Accordingly, the cause of the accident was determined to be during a flight at an altitude of 300m, the plane suddenly lost control (possibly the control system was broken or jammed), causing the plane to dive at a large angle, speed and tilt.

The flight crew made great efforts to bring the plane back to level flight but could not handle it (due to high speed and rapid loss of altitude), leading to the accident.
