Software Won’t Fix Boeing’s ‘Faulty’ Airframe
In essence, these critics say, Boeing’s response to the challenge posed by Airbus was bumping passenger safety to a middle seat in economy class while financial considerations were upgraded to First Class. Boeing denies this (www.eetimes.com) المزيد...

Why would they when they are already losing sales from Airbus?
And where do you base your claim? I would believe it when brand new 777s falling out of sky due to Boeing cheap out on material and installing old parts on new planes and selling those as new.
Boeing however made a mistake on thinking pilots would fall back to non-computer assisted flying, which in both crash case the crew didn’t or mistakenly thought disabling autopilot will disable auto-trim. And turns out later both 737 doesn’t have AOA indicator or instrument disagree indicator which may warned the pilots to give them situation awareness, both were options that those AIRLINES CHEAPED out on.
Boeing have faults, they tried to rush 737 into the market and in service, not because of money but because they are fighting to stay relevant to Airbus. FAA on the other had is doing the same, because Boeing jet is one of America’s biggest export, especially to countries like China they can’t sell missiles to. I am not saying that is the right thing to do, but they don’t exactly have a choice when someone else is taking away their bread and butter.
Last but not lest, in the end it was a software issue (unlike claimed by this “news article”), heck Airbus had a more prominent software error when their A320 “Landed” in the woods during an air show...
To Boeing’s defense, an aircraft’s computer system is always patched and way more complicated than your phone or your Audi Q7, when was the last time you heard Windows or your IPhone is new perfect and no longer need any updates? It will never happen until they decided no longer support your device.

MSM is blaming MCAS when in reality the question that should be asked is "Why are AOA probes failing on basically new airframes?". This and why did the pilots not pull the trim circuit breaker when the indications are awfully similar to a run away trim motor.
A faulty pitot probe was the mechanical factor in the crash of Air France flight 447. Resulting in a fleet wide replacement of the part
Interestingly enough one of the post investigation sugestions of AF447 was to add AOA indicators to the instrument panel but ultimately this was not mandated.

I agree with your opinion as it reflects what I was concluding also.
I agree as well... I think they need some hardware design changes.. 1 in particular, A guarded push off switch for starter on the Glare Shield in easy reach of both crew members!
This article have 0 common sense when talking (s**t) about 737’s engine placement. ALL aircraft pitch up when accelerating, this is due to wing aerodynamic tendency to pitch up when the wings generate lift (the airfoils commonly used on wings will generate a positive pitch moment, aka pitch up. You will need special airfoil to prevent it happening to flying wings like B-2 bomber) the tail plane is there to generate a normally negative force to balance it out, even in level flight. In addition, on aircraft with engines mounted on wing pylons, the engine will pull forward and try to rotate upward, just like if you have a pen laying on the table and push the tail perpendicularly to the pen, the pen will rotate upward...
The second effect is actually why most airplanes have their engines under and forward of the wing, because this way when the engines are running like in cruise conditions, there would be less stress and twisting in the wings, lightening wing structures.
As for 737 MAX, to make room for the larger LEAP engine, the engine mounting puts the engine higher further FORWARD makes it have LESS tendency to pitch with same thrust settings...Yes there will be some changes to the handling characteristics, but the general layout, dimensions, control characteristics are similar to NG, heck even 757 and 767 are sharing the same type rating and one of them is a wide body and the other is a narrow body... you don’t need to get a new license when you buy a new car do you? (Think type rating like this, you don’t need a new license when switching form a Civic to a Grand Cherokee, but you will need a new license to drive a Semi-truck if you never done so)
The problem why these 2 planes crashed are simple, poor machine-human integration and poor training. The former is Boeing’s fault for not indicating MCAS was activated (unlike stick shaker and stick pusher which have very physical indication when the yoke is shaking/moving). The latter is airlines’s (as well as Boeing’s) fault, pilots should actively disconnect all automated control/stability systems and revert to flying the aircraft themselves (If they done that they would disabled the auto trim, which will disables MCAS), and Boeing should have emphasized the MCAS addition to MAX when doing the “upgrade” training, especially when it is part of flight control system. (I think Boeing left out troubleshooting MCAS in flight manual because they expect the pilots will disable auto-trim when the plane’s nose started to dip unexpectedly.
