JAKARTA, Indonesia — The fatal crash of Lion Air Flight 610 last year was caused by systemic design flaws in the Boeing 737 Max that were compounded by flight crew lapses, Indonesian investigators told the relatives of victims on Wednesday. Two years after the plane operated by Indonesia's Lion Air plunged into the Java Sea, killing all 189 on board, the tragedy is still raw. The popular 737 Max has been grounded since March as aviation regulators investigate the Lion Air disaster and a similar crash of a 737 Max operated by Ethiopian Airlines. But the airline's maintenance crews and pilots couldn't identify the problem because one of the aircraft's safety features — the AOA Disagree alert — was not "correctly enabled during Boeing 737-8 (Max) development," they said. Kevin McAllister, third from right, was ousted this week as head of Boeing’s commercial airplanes division. “With the blindfolds that the pilots had on because Boeing didn’t include MCAS in pilot manuals, along with the flood of alerts, conflicting distractions in the cockpit and the now-understood relentless power of the old MCAS, even the most experienced and highly trained pilot would be challenged to recover the aircraft in the seconds required,” said Dennis Tajer, a spokesman for the union that represents American Airlines pilots. A synopsis of the report, presented in slide-show format to victims’ relatives, put the bulk of the blame on Boeing for introducing an automated system in the Max without adequately briefing airlines and their crews about its existence or instructing them how to override the software should it malfunction. As such, the last flight crew was not fully aware of the earlier problems.

"The U.S. authorities shouldn't have lifted the grounding order this quickly," said Aris Sugiono, who lost his sister and brother-in-law in the crash.
