The Federal Aviation Administration of the United States, which investigated Boeing's 737 Max on the ground after two crashes caused by onboard systems malfunctions, has discovered another, non-related safety issue. Reuters was the first to report the news, the sources of which indicate the new security issue was discovered in simulator tests last weekand now Boeing faces increasing delays, including the possible need for hardware fixes, before the airworthiness certificate of its 737 Max can be recertified.
Another e-mail statement from the US regulator confirmed, without explaining, that "the FAA has recently found a potential risk that Boeing must mitigate." With reference to two sources who are familiar with the case, Bloomberg reports that "Data processing by an aircraft computer on the jet can cause the aircraft to dive in a way that pilots struggled to recover in simulator tests."
Boeing told from his side Bloomberg that it is consistent with the findings of the FAA and is working to resolve the newly discovered security risk, along with a more extensive redesign of software that has been in the works for eight months.
