Senior Airman Max Bustamante, 22nd Maintenance Squadron non-destructive inspection Airman, inspects a fuel nozzle pin for damage under a blacklight, Jan. 25, 2016, at McConnell Air Force Base, Kan. Blacklights are used by NDI-Airmen to look for defects that cannot be seen in regular lighting conditions. The backlight illuminates the applied phosphorus chemical that the parts are dipped in to highlight any damage the part may have. ( Air Force photo/Airman Jenna K. Caldwell)
