Case study: Boeing 737 Rudder Servo. VERY, VERY similar history to MAX/MCAS (2x crashes, plus additional inflight control incidents). 737 was never grounded for that issue. Should it have been?
I guess that’s kinda my point. The old way doesn’t work any more. If this happened 20 years ago, would the airplane have been grounded? Doubtful.
The PCU issue was arguably way more dangerous and yet it continued flying.
