## Discrepancy

AIRCRAFT WAS GROUNDED: WHILE TROUBLE SHOOTING A FAULT MESSAGE FOR THE EMERGENCY LIGHTING SYSTEM MAINTENANCE REPLACED THE AFT LEFT SLIDE AND NOTED IT WAS BAD FROM STOCK AS IT FAILED THE EMERGENCY LIGHTING TEST. THE BAD FROM STOCK SLIDE WAS REPLACED AND ROUTED TO BE SENT OUT FOR REPAIR. A SERVICEABLE SLIDE WAS INSTALLED AT THE AFT LEFT POSITION. PER JOB CARD 26L00025010 AND A SATISFACTORY OPERATIONAL CHECK OF THE EMERGENCY LIGHTING SYSTEM WAS ACCOMPLISHED.
