## Discrepancy

NR 3 EMERGENCY LIGHT INOP IN SUPERNUMERARY COMPARTMENT CEILING AND BOTH SPARE EMERGENCY LIGHTING BATTERY POWER SUPPLIES ARE INOP. WHILE THE AIRPLANE WAS GROUNDED, THE EMERGENCY LIGHTING BATTERY POWER SUPPLIES AT POSITIONS M734, M736, AND M737 WERE REPLACED. THE CAUSE OF THE INOPERATIVE EMERGENCY LIGHTS WERE FAULTY BATTERIES.
