## Discrepancy

DURING LINE CHECK, MAINTENANCE FOUND THAT THE EMERGENCY PATHWAY LIGHTING IN ROWS 18-21 OF THE CABIN WERE INOPERATIVE.  FURTHER INSPECTION REVEALED THAT THE WIRE HARNESS UNDER SEAT ROW 20 AND 21 WAS SMASHED AND CAUSING A SHORT.  THE WIRING WAS REPLACED, AS WAS THE FUSE, AND THE SYSTEM FUNCTIONAL CHECK WAS GOOD.
