Airman 1st Class Tage Sickler 92nd Maintenance Squadron hydraulics systems apprentice, prepares to attach the ruddervators to the refueling boom Dec. 16, 2016, at Fairchild Air Force Base, Wash. There are two slots on either side of the torque tube where bolts can go through, keeping the ruddervator from rotating within the bell crank, allowing the ruddervator to be controlled.
