The American company Boeing found flaws in the 737 Max aircraft software that were previously unknown. This may lead to the fact that flights of these airliners, stopped almost a year ago, will resume very soon.
According to Reuters and France Press, citing the press service of the company, shortcomings were discovered during a technical audit. It turned out that the system does not work correctly on the aircraft, which checks the operability of some units before the flight.
Reuters notes that the incident will further delay the return of the liner to the sky – the company, however, deny it. Boeing says they are already working to resolve this error and hope that a solution will be found in the very near future.
This is not the first defect identified on the Boeing 737 Max in recent years. Earlier in January, it became known that Boeing and the US Federal Aviation Administration (FAA) found wiring problems in the aircraft.
We are talking about two bundles of wires that are so close to each other that in flight, because of this, a short circuit can occur, which in turn can lead to the crash of the airliner.
All these shortcomings were discovered during inspections of the aircraft, which took place after the suspension of its flights, the cause of which were two plane crashes at once, which happened with a difference of several months.
The first of them occurred in October 2018 in Indonesia, killing 189 people. The second – in March 2019 in Ethiopia, then 157 people were killed. During the investigation, it turned out that the reason was new software, which pilots were not trained to work with.
This is a system that corrects the position of the aircraft. In the event that it seems to him that he is losing speed, she automatically lowers the nose of the plane so that he again picks it up. However, the pilots did not know anything about the new feature.
As a result, due to a sensor failure, the system in both cases began to lower the nose of the aircraft in a situation where this was not required, and the pilots did not know how to deal with this and how to turn off the system.
At congressional hearings on these incidents, it turned out that the FAA had predicted the likelihood of another 15 liner crashes after the first crash for the same reasons, but did not suspend their flights in the hope that Boeing would quickly solve the problem.
Initially, Boeing stated that flights would resume by the 2019 Klintse, but later it turned out that this forecast was too optimistic. The liner still has not received permission to resume flights – and airlines expect that it will return to the sky no earlier than June.
