[Global Times-Global Network Reporter Guo Yuandan and Zhao Juejuan] According to CCTV reports, after the accident of China Eastern Airlines, China Eastern Airlines has now controlled all the company's 737-800 flights on the ground, and will no longer perform flights after the airborne flights have landed. .
Relevant experts told the "Global Times" reporter that China Eastern's move is a routine action to prevent risks.
Why were all 737-800 flights grounded after the crash?
Does this mean the 737-800 is a potential risk?
In this regard, Li Xiaoguang, chief professor of Qingdao University and dean of the Institute of Intelligent Unmanned Systems, told the Global Times that it is a routine action to prevent risks until the cause of the accident is known.
"After years of operation and use, there should be no problem with the aircraft itself. The possible causes of the accident include whether the maintenance and repair meet the airworthiness requirements, whether the pilots have operational errors, other human or special events, etc." Li Xiaoguang suggested that Boeing as the aircraft Manufacturers will participate in accident investigations after obtaining permission from relevant Chinese government departments.
In the process of judging the specific cause of the accident, the black box is especially important.
After the air crash on the 21st, the relevant person in charge of Boeing China said that Boeing has seen relevant reports and is collecting more information.
Public information shows that the Boeing 737-800 that crashed this time belongs to the 737NG series passenger aircraft, which is not the same series as the previously grounded 737 MAX 8.
The 737NG series passenger aircraft includes 737-600/700/800/900 and other models, and is currently one of the most widely used narrow-body passenger aircraft in the world.
Statistics show that civil aviation companies in mainland China operate nearly 1,400 737NG series passenger aircraft, accounting for 37% of China's total civil aviation fleet.
