I always get a negative reaction for mentioning the Emergency Airworthiness Directive sent to all MAX pilots. Media accounts never mention it, either.

The Boeing Emergency Airworthiness Directive says:

"Initially, higher control forces may be needed to overcome any stabilizer nose down trim already applied. Electric stabilizer trim can be used to neutralize control column pitch forces before moving the STAB TRIM CUTOUT switches to CUTOUT. Manual stabilizer trim can be used before and after the STAB TRIM CUTOUT switches are moved to CUTOUT."

For those who are skeptical of mainstream media fake news on the topic, here's the official final report on the Lion Air crash:

2018 - 035 - PK-LQP Final Report http://knkt.dephub.go.id/knkt/ntsc_aviation/baru/2018%20-%20...

I also recommend the recent Aviation Disasters episode on it. While shallow, because it has to fit in 40 minutes, I was shocked that it was surprisingly accurate. Kudos to the Smithsonian channel. I wouldn't be surprised if AD waited until that report was released before doing the episode, so it would be using verifiable facts.

> The Boeing Emergency Airworthiness Directive...

One out of 313 active AD's [1], 12 with no effective dates that seems to signify a different class of AD's because their issue dates are all over the map. I'm okay with 313 patches that I apply and the computer executes it from then onwards. Above a certain limit of number of AD's that should be memorized by pilots at all times, instead of entered into maintenance tracking systems for example, I'd like to hear from pilots why safety-wise that doesn't trigger a type re-certification.

I know that is expensive and time-consuming, but I certainly don't expect for example, my most senior ops team members to recall off the top of their heads more than a handful of critical procedures to execute on-the-spot without referring to the runbooks. Why does it appear that AD's are expecting pilots to apply a seemingly unbounded number of these "patches" like computers without re-training?

Your link is to Airworthiness Directives. The one I linked to is an EMERGENCY Airworthiness Directive. This EMERGENCY AD was about an actual crash of the same airplane, and contained a 2 step procedure from recovering from the MCAS malfunction.

It's a whole two steps:

1. trim back to normal with the electric trim switches

2. turn off the trim system

Not only that, this is what they're supposed to know anyway. Recovering from stab trim runaway is supposed to be a memory item, meaning memorized.

If you were a MAX pilot, wouldn't you pay attention to this?

People make mistakes, especially in high pressure situations.

What are you trying to say, exactly?

Not sure what you find confusing about it.

Are you saying the pilots should have been able to handle it? Training wasn't needed? Obviously you're trying to make a point but you aren't saying it, you're just presenting supporting details. So I'm asking you to clearly state what the take away from all that is supposed to be.
