All about Boeing 737 MAX 8s

At what point are the surveys on the Boeing 737 MAX

There are doubts about the process that led to the certification in the United States of models fallen in Indonesia and Ethiopia, meanwhile almost 400 remain on the ground.

Since March 2019, nearly 400 Boeing 737 MAX airplanes have been on the ground following the serious Ethiopian Airlines flight 302 (ET302) crash, which crashed in Ethiopia shortly after take-off, killing 157 people. Most airlines and flight safety authorities have decided to suspend the use of the 737 MAXs in their different configurations, waiting to clarify the causes of the accident, which has many similarities with that of the Lion Air flight took place last October in Indonesia. There are above all doubts about the role of the Federal Aviation Administration (FAA), the government agency that deals with civil aviation in the United States, and about how it managed the approval process of the new Boeing then put on the market.

Boeing 737 MAX vs. Lion Air 610 According to statements made so far by the Ethiopian Ministry of Transport, the data recovered from the black box of the precipitated Boeing 737 MAX 8 indicate several similarities with those of the Indonesian Lion Air 610 flight, which fell IN 2018 with 189 people on board. The model of the plane was the same and it is suspected that the two accidents were caused by the malfunction of one of the automatic flight attitude control systems, which would have led the two planes to lower the nose repeatedly, compromising the climb in cruising altitude immediately after take-off.

The suspects are concentrating on the Maneuvering Characteristics Augmentation System (MCAS), a system that serves to prevent the airplane from stalling, meaning that it loses lift, the force that allows it to remain in flight. The MCAS is activated by modifying the attitude of the tail and, according to the investigations carried out so far by the Ethiopian authorities, precisely that part of the plane was configured so as to lower the nose to the airplane. Data on the rise after the take-off of the ET302 flight indicate that the airplane has continued to take and lose altitude. In ground communications, the pilot also said he had problems with flight controls.
