B-2 Bombers are flying again after their “safety pause” (let’s not call it a grounding).

Also, according to Aviation Week, while grounded, orders went out for an undisclosed component to be inspected, which is believed to be a part of the flight control system.

It could be an air data sensor, or an actuator, or something in the stabilization augmentation system, or pretty much any sensor or actuator in the flight controls, but my guess (and my record on this sucks just as badly as everything else) is something in the fuel system associated with center of gravity management.
