It seems incomprehensible that American Airlines and Southwest Airlines can refuse to ground their B-737 Max 8’s while the rest of the world grounds theirs in the face of two accidents that have claimed the lives of nearly 350 people.
There would not be enough money in the world to pay the punitive damages claims that either airline would have to pay in the event one of their Max 8’s dived into the ground because the MCAS failed again.
Today Boeing announced a software fix that reduced the control authority of the MCAS so the elevators would still be able to allow the crew to pull out of a dive induced by runaway stabilizer trim and added a comparator so if either Angle of Attack sensor disagreed, the system wouldn’t work. This is a good first step but the airplane should never have been certified by the FAA without those features in place. It has a single point failure, one sensor operated the system at a time, and this emergency system alone created a worse emergency.
Do American and Southwest’s Max 8’s already have the software or some version of it that the International carriers do not have? If so the culpability of Boeing would be worse, if that’s possible, but the FAA would also have to be complicit which would explain why it rushed to defend Boeing and the decision of American and Southwest not to ground their fleets. If American and Southwest have a revised MCAS and they remain silent about it, they are morally corrupt for remaining silent.
There is no evidence that the U.S. carriers’ aircraft are any different than those sold overseas but something is driving this arrogance in the face of certain disaster.
