The way I see it it is to approve or disapprove whatever Boeing and FAA has cooked up this time.
After all it was China EASA and Canada that grounded the Max and not the FAA.
Having the FAA in the group invalidates anything the Group finds.
The Question with a big Q is can we trust FAA?
Answer is: Not for now.
So as Canada put it bluntly: Whatever FAA certify , we will also have to certify independently!
No more trusting the FAA, for now.
I would also add that there is such a practical pressure. ( What if it is permanently grounded?)
And economical/political pressure . ( Boeing existence, ultimately!)
That leads me to think this so-called group is rather a joke.
