There is also an issue with the engine anti-ice. The LEAP engine nacelle lip uses more composite materials than the legacy nacelles and can catastrophically fail if the anti-ice is left on in dry conditions for more than five minutes! The AD warns this could result in “an un-powered off-field landing”!

Yeah…but it shouldn’t be on without visible moisture or a contaminated surface, so this damage occurs outside of proper system operation. Not a real shocker.

Yup. Nobody ever forgets to turn it off ….

Lol, exactly. Forgetting to turn off the anti-ice for 5 minutes and you get a total engine failure? That's the definition of a "real shocker."

And of course anti-ice valves never stick in the open position! 
Boeing has auto anti-ice systems that automatically turn on and off during icing conditions but to maintain the same type rating as legacy 737 aircraft, these type of systems are not installed on the Max.
The Max with the LEAP engines should have had a new type certificate but Southwest would have not have purchased the aircraft to begin with and so Boeing did a lot of pounding a square peg in a round hole to emulate handling characteristics of legacy 737.

Even the NG had a different wing and cruised faster than the 100 to 600 aircraft and it could be argued that Boeing should have changed the type certification back then.

Good.  Maybe we can actually hold  Boeing accountable for making pieces of shit both for the USAF and civilian world.  Monopolies are not good for competition and and definitely not good for making end products that are safe and effective vs. a product that constantly needs more work to function as advertised.   

Fuck Boeing.  They are not as good as they think they are.
