Lion Air is probably an outlier, but then again, what if all 3 have trim management in common? Because at least Lion and FlyDubai do.
In Addition Fly Dubai and Atlas both share low visibility and approach/final, right? And somebody mentioned constant speed. It seems Atlas air was actually slowing down and FlyDubai was just slightly accelerating, both despite nose down, if FR data is to be trusted (can't post links, sorry).
Seems like some kind of a pattern, doesn't it?
Not at all. Statistics is about accepting or rejecting hypotheses that are made in advance of knowing the data. Claimed confirmation of a hypothesis that was generated after seeing the data is just cherry-picking. Given there are so many parameters to cherry-pick from, it is sure that you can find some that will all align between the incidents -- but this has no probative value as statistical inference. Indeed, each of these crashes is so different from one another in terms of the stage of flight, that I doubt any similarity will be found. And note that trim problems generally don't cause an immediate nosedive into the ground. You generally see the flight crew struggling with the imbalances for some minutes (or at least multiple seconds) before control is finally lost. That doesn't seem to be the case with the altitude profile shown here.
