Parts in parts out
Senior Airman John Aubuchon, 20th Aircraft Maintenance Unit communication navigation journeyman, inspects a part needed for a red-ball maintenance action at Barksdale Air Force Base, La., July 18. Red-ball maintenance is when an aircraft has aircrew on-board and the plane is waiting for a problem to be fixed so it can take off on its mission. (U.S. Air Force photo/Staff Sgt.
