Guo Qing, an associate professor at the School of Aviation of Northwestern Polytechnical University, said in an interview with Guoshi Express on the 21st that he was very sad after hearing the news of the China Eastern Airlines plane accident.BoeingAmong the company’s aircraft, the 737-MAX has had many accidents in recent years. “Guo Qing believes that,BoeingIn the design process of the 737-MAX, the designer may have “rushed ahead” and other reasons, and directly used a larger engine to increase the capacity and load performance of this type of aircraft, which caused the center of gravity of the aircraft to move forward. A series of changes such as the increase of the landing gear, and the design defects of the flight control system and insufficient training of pilots are also the main reasons for the frequent accidents, so that my country still grounds the 737-MAX.Guo Qing said that with the relatively high accident rateBoeingCompared with the 737-MAX, the 737-800 in this accident is an old model that has been running for at least 10 years, with relatively stable performance and is more popular in the market. However, it does not rule out the possibility of problems or related defects in the aircraft of different production batches in the later stage.
