EU air safety regulator doubts reliability of new computers in Boeing 737 MAX

The European Aviation Safety Agency (EASA) informed its U.S. colleagues and The Boeing Company that it did not consider the tests carried out on a number of computer systems that equipped the Boeing 737 MAX aircraft to be sufficient ones, Trend reported with reference to TASS, according to the Wall Street Journal’s report on Tuesday.

According to these sources, we are talking about two computers that are part of the airliner control system. Boeing believes that if one of them fails, the second one can fulfill its functions. This principle of operation was proposed by the company as one of the measures to improve the reliability of aircraft after suspension of their operation.

Experts from the European air safety regulator believe that tests conducted by Boeing and employees of the U.S. Federal Aviation Administration (FAA) do not prove that computers will work properly in case of emergency. According to sources, this means that the return of the Boeing 737 MAX to operation may be delayed. The publication notes that representatives of the European air safety regulator did not provide an exhaustive list of recommendations on how to test these computer systems.

The operation of the Boeing 737 MAX aircraft was suspended after two accidents. On March 10, Ethiopian Airlines’ Boeing 737 MAX 8 crashed in Ethiopia, killing 157 people. On October 29, 2018, 189 people became victims of the crash of an aircraft of a similar model of Lion Air in Indonesia.

Boeing management acknowledged that in both cases on board the aircraft there was a malfunction in the system to improve maneuverability before they crashed. After that, many countries, including Russia, the United States and the European Union, for safety reasons, suspended the operation of aircraft of this series.
