The spoilers are part of the upper wing surface. The recovered Spoiler shows evidence of collapse in a deployed position.
Why would the Port Outer Spoiler (the recovered one) have been deployed?
My understanding is that the outer spoilers can only be deployed following both MLG on the deck when landing or in a RTO above 72KT. Both outer spoilers are not used for speed brake or roll.
The Speed Brake section in
A340 - A330 Control: Flight Laws gives a fairly concise description.
