## Discrepancy

DURING A ROUTINE OVERNIGHT MAINTENANCE INSPECTION MAINTENANCE REPORTED THAT THE AISLE EMERGENCY LIGHTS AT ROWS 7 THROUGH 11 WOULD NOT TEST.  MILWAUKEE MAINTENANCE FURTHER REPORT THE REMOVAL AND REPLACEMENT OF AN EMERGENCY LIGHT POWER SUPPLY BATTERY PACK AT FUSELAGE STATION 500.  A SATISFACTORY OPERATIONAL CHECK WAS ACCOMPLISHED PER AMM 33-53-00.  THE AIRPLANE HAS RETURNED TO SERVICE.
