Balance in the force
Staff Sgt. David Crouse, a jet engine mechanic in the F117 shop of Bldg. 3001, sets up a balance machine to test a low pressure turbine. The machine tests various sections of the engine, including the low pressure compressor. Sgt. Crouse is the first military mechanic here certified to balance the low pressure compressor and is working toward getting his certification on the other engine sections. The F117 powers the C-17 aircraft and is maintained at Tinker by members of the 545th Propulsion Maintenance Squadron. (Air Force photo by Margo Wright)
