Airmen conduct preventative MXS on C-130J fleet
U.S. Air Force Airman 1st Class James Schwein, 19th Maintenance Squadron nondestructive inspections journeyman, uses a black light to inspect an aircraft tow fitting arm for cracks Jan. 19, 2017, at Little Rock Air Force Base, Ark. Liquid penetrant fills in small cracks causing them to become fluorescent under black lighting, making it easier to detect cracks and corrosion.
