'What the Truth Is': FAA Safety Engineer Slams Oversight of Boeing's 737 MAX

The Seattle Times reports:Haunted by the two deadly crashes of Boeing 737 MAX jets and his agency's role in approving the plane, veteran Federal Aviation Administration (FAA) safety engineer Joe Jacobsen is stepping forward publicly to give the victims' families "a firsthand account of what the truth is." In a detailed letter sent last month to a family that lost their daughter in the second MAX crash in Ethiopia two years ago this week, and in interviews with The Seattle Times, Jacobsen gave the first personal account by an insider of the federal safety agency's response to the MAX crashes... He believes additional system upgrades are needed beyond Boeing's fix for the MAX that was blessed by the FAA and other regulators. And Jacobsen argues that the plane would be safer if Boeing simply removed altogether the new software — the Maneuvering Characteristics Augmentation System (MCAS) — that went wrong in the two crashes that killed 346 people. Jacobsen also calls for the replacement of some of the people at "the highest levels of FAA management," whom he blames for creating a culture too concerned with fulfilling the demands of industry. In his letter and interview, Jacobsen also described in more depth than previously reported how an autothrottle system issue may have contributed to the crash in Ethiopia in March 2019. Boeing and the FAA said in separate statements they believe the MAX is fixed and safe, and that regulators worldwide have validated this conclusion... A week after the Lion Air crash on Oct. 29, 2018, Jacobsen received an email from a colleague asking if there was an issue paper on MCAS. "This was the first day that I heard about MCAS," he wrote. "We had no issue papers, and if we had, I would have been the engineer responsible for providing technical content and comment on such an issue paper." When he did get a look at the system, Jacobsen said he was "shocked to discover that the airplane was purposely designed and certified to use just one AOA (Angle of Attack) input for a flight critical function." If given the chance during the original certification, he's certain that he and "6 to 8 of our most experienced engineers in the Seattle office" would have identified that as a serious design flaw because there's "a long history of AOA sensor failures." Instead, Boeing minimized MCAS and kept the details of its assessment to itself... The article also argues that Boeing itself didn't grasp the danger of its system. "Michael Teal, 737 MAX chief engineer, testified to Congress that he first learned only after the Lion Air crash that MCAS relied on a single sensor.
