## Discrepancy

EMERGENCY FLOOR LIGHTING UNDER SEAT NUMBER 3 IS INOPERATIVE!  ADDITIONALLY THE LIGHT ABOVE SEAT 3 IS INOPERATIVE AS WELL. BOTH LIGHTS ARE TO BE ON DURING EMER LIGHT CHECK . CORRECTIVE ACTION; REPLACED THE #2 EMERGENCY BATTERY PACK REFERENCING TEXTRON MODEL 680A MAINTENANCE MANUAL (REV 21) CH 33-50.06. FOUND THAT THE G SWITCH HAD BEEN TRJPPED. RESET THE G SWITCH AND OPS CHECK GOOD.
