Accident process
Flight MU5823 takes off from Shanghai Pudong Airport at 7: 50 am and is scheduled to arrive at new york Kennedy Airport at 3: 30 pm. However, on the way, the crew found that a hydraulic system of the plane failed, which caused the left wing of the plane not to be fully deployed. The crew tried to balance the plane by adjusting the center of gravity, but failed.
Finally, the crew decided to make an emergency landing at Halifax airport in Canada. During the forced landing, the plane lost control and hit some obstacles beside the airport runway, causing the plane to catch fire. Fortunately, all the passengers and crew managed to escape, but 43 people were injured, two of them seriously.
accident cause
The accident investigation Committee finally determined the cause of the accident. They found that the failure of the aircraft hydraulic system was caused by the loosening of the connecting nut of a hydraulic oil pipe. After the nut is loosened, the hydraulic oil leaks during the flight, which leads to the failure of the hydraulic system.
In addition, the investigation Committee also found that the crew had some mistakes in handling the fault. They tried to balance the plane by adjusting the center of gravity, but they didn't consider that the speed and altitude of the plane would affect this process. In the end, this mistake led to the loss of control and collision of the plane.
The impact of the accident
After the accident, China Eastern Airlines took a series of measures to improve flight safety. They strengthened the training and supervision of pilots, improved the maintenance and inspection procedures of aircraft, and updated the technical equipment of aircraft.
In addition, the accident has also prompted the global aviation industry to conduct stricter review and supervision on the safety of aircraft hydraulic systems. Many airlines have taken similar measures to improve flight safety.
