FOLLOWING ACCOMPLISHMENT OF ALL CHECKLIST PROCEDURES, THE FIRE WARNING INDICATIONS REMAINED ON. THE CAPTAIN ORDERED AN EMERGENCY EVACUATION ON THE RUNWAY AFTER THE AIRPLANE LANDED. DURING THE EVACUATION, ONE PASSENGER WAS KNOCKED OFF OF THE WING BY AN OVERZEALOUS PASSENGER AND WAS SERIOUSLY INJURED.
