The US authorized the damaged Boeing despite their failures

Engineers from Boeing and the Federal Aviation Administration (FAA) approved an automated 737 Max software program without fully understanding its operation, despite a previous warning from a test pilot that the results could be “catastrophic.”

A devastating report released Wednesday by the Congressional House Transportation Committee reveals “a horrible culmination of errors” by the executives of the aeronautical company and the FAA in the process of approving the flight program. After an 18-month investigation into the two crashed flights involving 737 Max – the Lion Air in October 2018 and the Ethiopian Airlines in March 2019, in which a total of 346 people died – serious negligence has been revealed in the design and the official control mechanisms of the US Administration.

On both flights, the automated software known as MCAS (Maneuvering Characteristics Augmentation System) performed a false reading and determined the descent of the nose of the aircraft without the pilots being able to rectify and regain control of the aircraft. This key safety system, designed to counteract the Max’s tendency to roll up its front end and triggered by a false reading from a single sensor, was the cause of the crashes, which were only less than five months apart. .

According to the findings, the aircraft fell victim to flawed technical assumptions by Boeing engineers, a lack of transparency by its executives, and grossly insufficient oversight by the FAA. The report clearly indicates which company and the agency’s certification process oversight unit may have detected the flaws in the Max’s flight control system during the design stage.

Federal irresponsibility

It also denounces the enormous responsibility of the federal administration, whose policy of lax supervision with certain large firms, allowed Boeing to continue the flights of the 737 Max. Even months after the model’s first crash in Indonesia, a February 2019 check – finally handed over to Congress in May – “found no breach” of federal safety regulations. A month later, a second Max crashed in Ethiopia.

Congress exposes innumerable loopholes in oversight by Boeing, which it attributes a “disturbing pattern” of technical miscalculations and “troubling misjudgments.” According to the investigation, he missed multiple opportunities where he may have corrected the design and development of the Max.

The report also criticizes that it withheld crucial information from the FAA, its customers and the 737 Max pilots, including the existence of the new MCAS flight program. Its sole objective was to reduce costs and accelerate the model’s time to market.

The 737 Max is the best-selling aircraft in the history of aeronautics, a model that has generated billions of profits. According to estimates prior to the accidents, a 737 took off in the world every five seconds and about 1,250 Max were each in flight at the same time.

Boeing expects the 737 Max, which have been stranded on the ground since March 2019, to be able to fly again later this year or early 2021 once the fatal errors detected have been corrected.
