Senior Airman Chris Peterson, 919th Special Operations Aircraft Maintenance Squadron crew chief, inspects connections on a new propeller mounted on a C-146A Wolfhound, as part of a special maintenance training program March 23, at Duke Field, Florida. Staff Sgt. Andrew Roberts, 919th SOAMXS engine mechanic, looks on from below as an instructor. The program is designed to create maintenance specialists to operate interchangeably in deployed locations, keeping crews smaller and saving the Air Force money and manpower.
