Senior Airman William Wright, Tech. Sgt. Steven Lew, Tech. Sgt. Jeff Burgess, Master Sgt. James Johnson and Senior Airman Daniel Phillis, aerospace propulsion technicians with the 910th Aircraft Maintenance Squadron here, work to remove and clean guide cones from a C-130H Hercules aircraft engine mounting point, March 7, 2018. The team removed the engine from the aircraft during an isochronal inspection in order to swap it with a different engine. Maintainers clean the guide cones and ports when they swap engines to prepare them for inspection and ensure they’re in good repair. The guide cones help ensure proper alignment when mounting the engine to the aircraft. (U.S. Air Force photo/Eric M. White)
