Perform a procedure is one thing.
Now how does a crew discover that the trim is misbehaving, requiring this specific procedure ? How long has a crew before things get out of hands ? Is the 737 MAX certifiable in this respect ? To date Boeing doesn't seem to have come up with a satisfying answer.
In the eye of the EASA, at least.
