## Discrepancy

BEFORE PUSH BACK, CAPTAIN REPORTED THAT AFT STAIR LIGHT TURNED ON.  MAINTENANCE PERSONNEL DETECTED SWITCH S1-277 DAMAGED, SO IT WAS REPLACED IAW MM 52-70-10, TESTED CORRECT.  AFTER THAT, MAINTENANCE PERSONNEL DETECTED A FUEL LEAK IN BOTH WINGS, SO AIRCRAFT WAS SENT TO THE HANGAR AND THE FUEL TANKS WERE OPENED, DETECTING DAMAGED SEAL IN THE LT WING FUEL TANK AND A NUT MISSING IN THE RIGHT WING FUEL TANK, SO SEAL WAS REPLACED AND NUT INSTALLED IAW MM 57-30-03 AND SRM 51-30-0, TESTED CORRECT.
