An expert on a news story said that the found piece did not have leading edge damage indicating it did not suffer a head on collision. Watch the wing in this video from an out of gas plane trying to land on the water. It was ripped off by centripetal force when the other wing hit the water. |

So the flaperon survived the wing break up, surely there must be clues in there. As has been shown with other accidents, you really have to have a lot of luck and skill to ditch successfully, more often that not its going to end with a break up of the aircraft. Its going to be smashes to tiny bits if it hits the water with terminal velocity. At least something has been found! The rest must be out there, luckily we have the Aussies with deep pockets and lots of toys on the case. --- End quote --- I think that unless the apu was running (not sure if that has it's own tank or not) that the autopilot would not be able to move any of the control surfaces. Even if it did have fuel it may not have been powered up (a pilots duty). In that case the plane could glide but outside forces could cause it to dive, spin or stall. |

As regards flight recorder data lifetime, if it is a recent enough model to use solid-state storage, it ought to be possible to recover data from the flash chips for decades - seawater might corrode away the pins of the chips but it still ought to be possible to access the dice. Tape may be less robust and more dependent on how well sealed it is against water getting to it. |

One of the last pings was interrupted and they figure that was when the fuel was actually running out and the turbine was deployed. |
