oldoberon, could not have put it better myself
This debris might be from MH370 then again, it might not
This statement by itself is true. However one must look at it in a broader context. If it is NOT MH370 then it MUST be a scrapped piece, because we KNOW that no operational T7 is missing one. As unserviceable and irreparable aircraft components must be physically destroyed to prevent re-use (with associated documentation), unless there is evidence that a T7 flaperon withdrawn from service (or rejected at manufacturer) could have been dumped in the Indian Ocean in a location that would facilitate it ending up at Reunion, the most plausible explanation remains that it is from MH370, the host of the only set of flaperons known to be missing. As flaperons are not exactly consumables, I'm sure it will not be all that difficult to account for those which are not attached to an operating airframe.
