Man on the Stand

Tech. Sgt. Ronnie Graham, 403rd Maintenance Squadron jet engine craftsman, removes the panel from a WC-130J engine in preparation for a “man on the stand” check May 1, 2015. Mechanics have to check for bleed air leaks while the engine is running to locate the oil leak. (U.S. Air Force photo/Maj. Marnee A.C. Losurdo)
