## Discrepancy

DURING A ROUTINE OVERNIGHT SERVICE CHECK INSPECTION MILWAUKEE MAINTENANCE REPORTED THAT THE FLIGHT DECK EMERGENCY LIGHTS WOULD NOT TEST.  MILWAUKEE MAINTENANCE FURTHER REPORT THE REMOVAL AND REPLACEMENT OF THE BATTERY PACK AT EMERGENCY LIGHT POWER SUPPLY BS-23.  A SATISFACTORY OPERATIONAL CHECK WAS ACCOMPLISHED PER AMM 33-53-00.  THE AIRPLANE HAS RETURNED TO SERVICE.
