A preliminary report on an Ethiopian Airlines crash will very 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.
