Last time I read about this topic, they concluded from the flapperon condition that it was a carefully controlled landing.
The article attached claims the opposite – it says that that flapperon condition shows that it broke off in-flight rather than on impact.
I didn’t mean in-flight breakup. I meant that to get flutter on any control surface, the aircraft would need to be going way above Vne. @pilot_dar knows more but probably 30-50% above.
Then it would break up upon impact with water.

If you go so fast that you get flutter, you should leave a huge floating wreckage field.
Flutter can affect only one surface. E.g. if only a flapperon was affected, it would be teared off and the aircraft would probably spiral down before other parts would be subjected to in-flight breakup.
I still don’t get it. If you go so fast that you get flutter, you should leave a huge floating wreckage field.

I don’t get what that analysis tells us.
The mechanism of ripping off flapperon in-flight (as consequence of flutter) is different than the one caused by impact.
I don’t get what that analysis tells us.
I would expect a deployed flap to be ripped off on a water landing, and if someone was trying to disappear without leaving debris they would do a water landing with flaps, because with zero flaps the approach speed is much higher.

Thanks. According to this, there’s no way controlled flight was conducted until impacting the water as it was suggested previously in this thread.

The recovered flaperon shows damage caused by in-flight separation which is consistent with fuel exhaustion.
Wasn’t it post-crash separation when hitting water surface?

Guilty as charged – although not the Costa and not a Brit anymore :)
