## Discrepancy

DURING A MAINTENANCE VISIT, THE EMERGENCY ESCAPE PATH LIGHT AT SEATS 54H, 43C, LAV 4L1 AND LAV 2R WERE FOUND TO BE INOPERATIVE.  MAINTENANCE REPLACED THE PATH LIGHT ASSEMBLY AT THE FRONT OF LAV 4L1 AND RELAMPED BULBS AT 54H, 43C AND AT THE FRONT OF LAV 2R.  SYSTEM OPERATION WAS NORMAL AFTER THE  LIGHT ASSEMBLY AND BULBS WERE REPLACED.
