Prop shop keeps engines cranking

YOUNGSTOWN AIR RESERVE STATION, Ohio -- Tech. Sgt. Steve Lew, an aerospace propulsion craftsman with the 910th Maintenance Squadron here, rebuilds a C-130H Hercules aircraft engine turbine, July 6, 2017. Due to the extreme heat made by the turbine, components eventually wear down and are replaced when found during periodic inspections. (U.S. Air Force Photo/Senior Airman Jeffrey Grossi)
