We shouldn't - of course - jump to conclusions, but that sounds a very plausible scenario for AEA's mishap. If that is the case, good for them that someone else had problems. Is it noted if the 146 had probs before or after AEA? if before, and it was reported to tower, one would like to think that subsequent crew were notified, but I know how these things are sometimes categorised as "one-off" and the communication doesn't happen, unfortunate if that turns out to be the case.
