China News Service, January 22 (China News Business Reporter Ge Cheng) According to multiple media reports, on January 21, a Sichuan Airlines flight from Changchun to Chengdu was climbing when the right engine suddenly sprayed flames. .

After circling for nearly two hours, the plane returned and landed at Changchun Longjia International Airport.

　　The reporter verified the matter with Sichuan Airlines on the 22nd. The customer service staff said that on January 21, flight 3U8424 Changchun-Chengdu Shuangliu returned due to a malfunction warning message. The aircraft landed safely at Changchun Airport at 14:33, and the passengers disembarked and went to the terminal. Rest, then change planes and continue to your destination.

　　According to the information from Air Travel Zongheng, the model of the aircraft involved is Airbus 321 (narrow-body aircraft). It took off at 12:44 on the 21st and was scheduled to arrive at 16:35 on the same day. The actual arrival time was 00:10 on the 22nd. The delay was more than 7 hours.

　　In addition, the malfunctioning aircraft circled 16 times over Changchun for nearly 2 hours.

  Aviation information shows that the flight involved circled 16 times over Changchun before landing.

　　Why did the plane hover in the air for 16 times before landing after a malfunction?

Civil aviation expert Li Hanming told reporters that when the aircraft takes off normally, there is a certain weight of aviation kerosene in the fuselage, which makes the fuselage heavier.

Therefore, the aircraft needs to consume a certain amount of aviation kerosene to "slim down" before it can land safely.

　　In addition, the methods of "downsizing" for wide-body aircraft and narrow-body aircraft are also different.

Li Hanming said that generally speaking, wide-body passenger aircraft will open the fuel release valve in a designated area in the air to release fuel; while narrow-body passenger aircraft need to hover in the air to "burn fuel" for a period of time.

　　As for the cause of the fire, Li Hanming said that the aircraft engine fire may be caused by a variety of reasons, which is currently difficult to determine.

"Most aircraft accidents can be controlled, and airlines have mature processes to deal with various emergencies." (End)
