Airman 1st Class Cody Knott and Senior Airman Paul Goodrow, both Det. 303, 442nd Aircraft Maintenance Squadron structural maintenance apprentices, replace an A-10 Thunderbolt II’s door hinge at Whiteman Air Force Base, Mo., July 1, 2013. The old hinge is removed from the door and is used as a template to align the holes in the new hinge. If the hinge is old and worn out, the A-10’s door will not open.
