Senior Airman Samuel Carr, 28th Maintenance Squadron repair and reclamation technician, removes a flap slat torque tube limiter during an isochronal inspection at Ellsworth Air Force Base, S.D., April 10, 2012. This system monitors the amount of torque in the flat slat, and the inspection ensures that flaps don’t lock up during flight. (U.S. Air Force photo by Airman 1st Class Alystria Maurer/Released)
