Boeing tied to 346 MAX crash deaths

A Boeing story that looked partly settled has opened back up. New U.S. investigative material on the March 2022 crash of China Eastern Flight MU5735 shows both engines on the 737-800 were shut off before the jet slammed into a mountainside, killing all 132 people aboard. That does not make MU5735 a 737 MAX story. But it has put Boeing back in the center of a much bigger argument about how much trust regulators, airlines, and passengers should place in the company after years of safety failures. ### Why is the China crash back in the news? Because the NTSB released flight-data material in response to a public-records request, and the data added a grim new layer: both engine fuel cutoff switches were moved before impact, and there are signs of a struggle in the cockpit. That points investigators toward deliberate action inside the flight deck, not a design flaw in the aircraft itself. China still has not published a final public report on the crash more than four years later, which is part of why this U.S. release landed so hard.

Ethiopian Airlines Flight 302 crashed in March 2019. Together they killed 346 people, and both crashes were tied to MCAS — the flight-control system that could force the nose down based on faulty sensor input. Those crashes became the defining case against Boeing’s engineering culture, internal disclosures, and regulator relationships. (apnews.com) ### What was the actual MAX failure? Basically, Boeing added MCAS to make the 737 MAX handle more like earlier 737s after larger engines changed the plane’s aerodynamics. The catch is that early MCAS relied on a single angle-of-attack sensor and could repeatedly push the nose down if that sensor fed bad data. Pilots in the Lion Air and Ethiopian crashes were overwhelmed by alerts and control forces that escalated fast. That is why the MAX grounding became global and why the company’s credibility broke so badly. (justice.gov) ### Didn’t the Alaska door-plug blowout change the story? Yes — because it widened the problem from design to manufacturing. On January 5, 2024, an Alaska Airlines 737 MAX 9 lost a mid-exit door plug shortly after takeoff from Portland. No one died, but the NTSB later said the probable cause was Boeing’s failure to provide adequate training, guidance, and oversight to ensure workers followed removal and reinstallation procedures. Investigators found the bolts meant to secure the plug were missing, and they also faulted the FAA for ineffective oversight of known recordkeeping issues. (justice.gov) ### Why do missing bolts matter so much? Because they turn “isolated mistake” into “system problem.” A modern jet is supposed to have layers of checks — paperwork, signoffs, inspections, and traceability. If critical hardware can leave the factory missing and nobody catches it, the issue is not one worker having a bad day. It means the production system itself is failing at basic control. That is why the Alaska incident hit Boeing so differently from a normal in-service malfunction. (ntsb.gov) ### Has the government actually eased up? Not really. The FAA capped 737 MAX production at 38 a month after the Alaska blowout, then later allowed Boeing to raise output to 42 a month in October 2025 — but only after extended scrutiny and continued oversight. Meanwhile, the Justice Department moved in 2025 toward a non-prosecution deal tied to the MAX crashes, with more than $1.1 billion in penalties, compensation, and compliance spending. Families of crash victims blasted that as too lenient. (ntsb.gov) ### What is the real issue now? Trust. The China Eastern revelations are not evidence that Boeing caused that crash. But they arrived in a world where Boeing is still trying to climb out of the shadow of 346 MAX deaths, a door plug that blew off in flight, and repeated questions about whether its factory controls are finally fixed. When new aviation records surface, Boeing is no longer judged incident by incident. It is judged as a system. (cnbc.com)
