The photos of the fenestron assembly showed some blades missing. Presumably all of these missing blades have been located and accounted for in the wreckage.
Indeed the blade at 3 o'clock and the one above ( not sure about this one, what we see could be a stator or blade ) are missing, the rest of the ten blades are still there, those around the missing ones are severely bent, so that could be the reason why they're not there, they've broken off.
