A preliminary report on the Ethiopian Airlines crash will likely be released this week, the country’s transport ministry said on Tuesday as Boeing prepares to brief more airlines on software and training updates on the 737 MAX. The aviation industry and grieving families of victims of the March 10 crash anxiously await details from the Ethiopia-led investigation. Boeing has come under intense scrutiny since the crash, the second in five months involving its new 737 MAX 8 model. The MAX software is the focus of investigations into the two crashes in Ethiopia this month and in Indonesia last year in which 346 lives were lost. This week, Boeing is briefing airlines on software and training updates for the MAX with more than 200 global airline pilots, technical experts and regulators due in Renton, Washington, where the plane is built. Any fixes to the MAX software must still get approval from governments around the world. The 737 MAX is Boeing’s best-selling plane.
