## Discrepancy

DURING TAXI, THE CREW NOTED A LEFT AIRCONDITIONING PACK OVERHEAT, AND LAV SMOKE WARNING MESSAGE.  AFTER RETURNING TO THE GATE, PIT MAINTENANCE INSPECTED AND REPLACED THE LEFT GROUND COOLING FAN IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 21-51-23.  THE LAV SMOKE SYSTEM WAS FUNCTION CHECKED IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 26-15-00.  ALL OPERATION CHECKS WERE SATISFACTORY AND THE AIRCRAFT WAS RETURNED TO SERVICE.
