Unless I’m missing something, they found the issue and that it was a “single point of failure” ages ago (single point as in - when something fails on planes as they often do, there is one or more than one failsafe workaround whereas in that instance there was not before it was identified and fixed)
They’ll have undergone a lot of scrutiny and testing by now to get it to the point it is allowed in the air so I would be as comfortable flying this one l, that has been tested to death, as I would be it’s predecessors by now.
