China Southern Airlines flight CZ311 departed from Shantou Airport at 8:40 am and is operating a flight from Shantou to Hong Kong. During takeoff, the aircraft deviated from the runway due to uneven thrust, Resulting in damage to the two engine blades, front landing gear, and rear skin of the left main landing gear wheel compartment of the aircraft, 85 passengers and 10 crew members on board are safe and sound. The plane has been repaired and resumed operation.
Possible reasons：The co pilot engaged the automatic throttle without confirming whether the thrust of the two engines was consistent, resulting in inconsistent thrust on both sides during takeoff and roll, ultimately deviating from the runway. The captain and observer did not play a supervisory role.
