Airman 1st Class Joshua Sprinkle, 4th Aircraft Maintenance Squadron crew chief, checks the gauges on a hydraulic reservoir as part of a 9th Air Force aircraft generation exercise, Sept. 10, 2015, at Seymour Johnson Air Force Base, North Carolina. Maintenance crews met the commander’s intent for the exercise by generating a dozen TDY-ready aircraft, all of which cleared the inspection team’s assessment. (U.S. Air Force photo/Airman Shawna L.
