393d AMU
U.S. Air Force Tech Sgt. Aaron Bradley, a 393d Aircraft Maintenance Unit specialist section chief, uses a socket wrench to adjust the front landing gear of a B-2 Spirit at Whiteman Air Force Base, Mo., Feb. 18, 2016. When needed, Bradley wears a headset to communicate with a second member in the cockpit—who applies hydraulic pressure. This method allows the crew to adjust the steering of the front landing gear without actually turning the wheel, which prevents wear on the tires. (U.S. Air Force photo by Tech. Sgt.
