## Discrepancy

DURING THE PREFLIGHT CHECK, THE CREW NOTICED THE MIDDLE SECTION FLOOR LEVEL EMERGENCY LIGHTS TO BE INOPERATIVE.  MAINTENANCE INSPECTED AND REPLACED THE BATTERY PACK IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 33-50-00.  OPERATION CHECKS WERE GOOD AND THE AIRCRAFT WAS RETURNED TO SERVICE.
