The new connections between the two crashes point to a potential systemic problem with the aircraft, adding to the pressure on Boeing. The company already faces scrutiny for its role in the design and certification of the plane. The Federal Aviation Administration delegated significant responsibility and oversight to Boeing...
If MCAS is so necessary because of the engine cowling moment in certain attitudes, wouldn't it be better to have a third AOA sensor to enable voting in the system. The bigger Boeing's and AB's have more than 2. The 737 is and is going to continue to be among the most numerous planes in the sky. Why not ensure it is as safe as them. I don't accept that saving a relatively small amount of money on a smaller airplane or quoting failures in the per billion hours is really valid when the larger planes have it, obviously for a good reason. There are far more 737's flying, far more takeoffs and landings making for just as much overall risk as the 777's and 787's (assuming more AOA's were provided for greater passenger capacity).
