A group of family members representing more than 50 people who died in the crash of Ethiopian Airlines Flight 302 are calling on the FAA to conduct a full regulatory review of Boeing’s 737 Max before it is allowed to fly again. The Max, which entered service in 2017, is Boeing’s most recent update to the 737, which was introduced in the 1960s. Because it was not an entirely new airplane, the FAA reviewed only the parts of the Max that differed significantly from a previous version of the 737. By certifying the plane with a so-called amended type certificate, the FAA allowed Boeing to get the Max flying years sooner than it would have had the company introduced a brand-new plane that had to be certified for the first time. But with scrutiny of the FAA mounting after the crash in Ethiopia and an earlier crash in Indonesia, the families of many victims are calling on the FAA to take an entirely new look at the Max. The plane remains grounded while Boeing works on a software update and other changes intended to make the Max safer. Michael Stumo, whose daughter, Samya, was killed in the Ethiopian crash, is leading the effort by the family members. “The FAA was lax, compliant and captured at the time of the amended type certification,” Stumo said Monday. “There needs to be a full recertification to catch anything and make sure it’s safe to fly again.” On Tuesday, the families sent a letter calling for the full recertification of the Max to Transportation Secretary Elaine Chao; the acting FAA administrator, Daniel Elwell; and the incoming administrator, Stephen Dickson. The letter also asked the FAA to require that pilots be trained on simulators before they could fly the Max. Relatives of people killed in other crashes, including the Max crash in Indonesia, also signed the letter.<br/>
