Phase Maintenance
KUNSAN AIR BASE, Republic of Korea -- Staff Sgt. Daniel Shawn, Airman 1st Class Patrick Bayless and Staff Sgt. Lance Wade deployed from the 79th Expeditionary Fighter Squadron, perform phase inspection on an F-16 aircraft here March 25. Every 400 hours, an aircraft goes through Phase Inspection, which extends its life span and prevents damages from day-to-day operation. (U.S. Air Force photo/Senior Airman Giang Nguyen)
