Just to clarify the AI position: Airbus changed the method of dealing with a locked out reverser last year but gave no reason for the change. Perhaps it was linked to the previous incidents?

I believe it is related to the Irkutsk S7 accident where most probably fingertrouble led to increasing thrust on one engine when reverse was being deselected on the other.
