Senior Airman Lucas Derflinger, non-destructive inspection journeyman, 108th Wing, performs a process control using a ketos ring and a central bar conductor on the magnetic particle inspection unit prior to inspecting aircraft parts at Joint Base McGuire-Dix-Lakehurst, N.J., March 7, 2015. The process control involves magnetizing the part, which is then bathed in a suspended particle bath. The bath seeps into the defects and when it is exposed to ultraviolet light – black light, causes the defects to become florescent and visible. The New Jersey Air National Guard NDI Airmen provide support to the structural maintenance program, which ensures that the KC-135R Stratotankers are mission-ready.
