And now USA will be grounding them too ! I'm glad it's come to this and now Boeing will have no choice but to fix whatever it is before they are allowed to fly those planes again.
Whatever may be the real intention of China to start grounding those planes, I'm glad they did it. Boeing wouldn't have looked at this accident seriously enough if the groundings hadn't gotten this level of momentum

FAA's Twitter post:
Not 'abundance of caution' etc - instead, "based on new evidence from the site" and "satellite data". Now this is getting pretty serious for Boeing, I'd say?

The MCAS issue actually relates to the aerodynamic lift generated by the bigger and relocated engine cowlings, and the need to compensate for that at high Angle of Attack.
You can see I have been reading PPRuNe intensively!

Oh, BTW, the Channel Islands authorities have banned the MAX from CI airspace [up to FL120, IIRC] ... not that the MAX could use any of our airports anyway!

And does anyone know if the 777x has the same issue? It has bigger engines and wings. I can’t find any information linking 777x and MCAS.

pprune was quite fun to read, I learned a bunch (loved physics in school) and got even more alarmed at how pilots were debating each other on the best way to handle MCAS issues, something that was supposed to have been settled after Lion Air!

Highly unlikely! Proportionally the 777x engines are not that much bigger and not being relocated further forward from the wing either. Non issue.

Wouldn't be surprised to see Ryanair negotiating lower prices with Boeing, bit of a one way bet. O'Leary is a great contrarian. But OT here I guess.
Waiting to see see what happens with my one MAX sector on AA, but as it's in August I suspect I amount be able to do a creative 9 sector rerouting.
Ergonomically MCAS seems to be a nightmare. It actually ratchets up the stress levels at a time of crisis. I wouldn't dare say this on pprune, but I strongly suspect disorientation and panic was a factor, and/or the jackscrew broke at the end. That seems to be the best 'found on the site' reason for changing tack.

Starting to look like some seeious systematic issues at Boeing. Their last two new aircraft types have both had a worldwide grounding order issued, first the 787 but thankfully no crashes and then the 737Max after 300+ deaths. Quite shocking really!
