DRIP DRIP DRIP: Boeing test pilots didn’t know how strong the 737 MAX’s anti-stall system was or that it depended on only one sensor, The Wall Street Journal has reported. Also in the spotlight: who Boeing told and when about an issue with the MAX’s angle-of-attack disagree alert. The FAA was told after last year’s Lion Air crash, but Boeing had been aware of the issue for months. And the FAA had been “set to issue a world-wide special safety information bulletin” about the problem, the Journal reports, but then “the Ethiopian crash intervened and the planes were grounded.”
