Boeing discovers a new bug in the software in the 737 Max

Boeing, plunged into the worst crisis in its history, has once again detected a new fault in the software on their model 737 Max aircraft, that "they must solve before they fly again". Researchers from the Ethiopian accident, which killed 157 passengers and the crew, have discovered that the aircraft was carrying an excessive speed and that it was pushed down by an automation system that shot incorrectly.

The newspaper "Washington Post" reports that in one of the reviews, the Seattle company, found that behind the disaster in Ethiopia and last year in Indonesia there could be an additional software problem in the stop prevention system. The Federal Aviation Administration of the United States (FAA) has ordered that it be resolved before these planes receive the authorization to fly again. For its part, Boeing wanted to clarify that It deals with a minor problem and is not related to the anti-blocking system.

The company's chief executive, Dennis Muilenburg, said that the publication of the preliminary report of the Ethiopian accident revealed that both the accident in Ethiopia and Indonesia, activated the system of increase of maneuver characteristics, known as MCAS, in response to the wrong detection of an angle during the maneuver. "As the pilots have explained, the erroneous activation of the MCAS function can put pressure on what is already a high workload environment. It is our responsibility to eliminate this risk. We have it and we know how to do it, "he said.

Asked about the report of a new software problem, Boeing clarified that: "We are making progress in updating the software that will prevent future accidents." Boeing has worked diligently, advancing and testing the software, in close collaboration with global regulators and customers, as well as with an independent review board.As part of this process, we have identified an aspect of the software, not related to MCAS, that will also be addressed as part of this software update.We are taking steps to address this relatively minor problem and we already have the solution".

In a statement, the FAA told "The Independent" that: "the FAA expects to receive the final package of Boeing improvements in the coming weeks." Boeing needs more time to perform new work on the flight control system of the 737 MAX and Check that Boeing has properly identified and addressed all problems. " "Once received, the FAA will submit it to a rigorous safety review. The FAA will not approve the software for the installation until it is satisfied with the package of additional measures introduced, "the US aviation added.

The pilot of the plane crash in Ethiopia, Yared Getachew, shouted "stop" three times before the plane crashed six minutes after taking off from Addis Ababa on March 10. "The crew performed all the procedures provided repeatedly by the manufacturer, but could not control the aircraft," Transport Minister Dagmawit Moges said at a press conference.

The preliminary report on the fall of the Lion Air 737 MAX in Indonesia suggested that the pilots also lost control after dealing with the MCAS software. A total of 189 passengers and crew lost their lives in that accident last October.
