Narrative:
At crew change first officer (first officer) did walk around and found the inboard flaps on both sides to be down approximately 5-10 degrees. Outboard flaps were stowed. When we checked the gauges in the cockpit; they indicated flaps 'up'; everything normal. We didn't fly the aircraft in; so I don't know what caused the damage. But if the first officer didn't catch it on the walk around the outcome would have been very different. System malfunction; flight controls; flaps.
