Senior Airman Austin Jackson, a precision measurement equipment laboratory technician from the 18th Component Maintenance Squadron, inspects the water trap of a TTU-205J test set at Kadena Air Base, Japan, April 29, 2021. A visual inspection is one of the first steps of ensuring the equipment is functioning properly. The technician looks for obvious problems, like disconnected wires, as well as more subtle issues like rust and corrosion. (U.S. Air Force photo by Airman 1st Class Anna Nolte)
