## Discrepancy

WHILE MOVING AIRCRAFT A CLICKING SOUND WAS HEARD.  AFTER LOOKING IN THE GAS CAP, A LARGE PART WAS FOUND SLIDING AROUND IN FUEL TANK.  AFTER A CLOSER LOOK, FOUND BROKEN WELDS ON INTERNAL RIB OR BAFFLE.  CAUSE WAS FUEL MOVEMENT IN TANK, AND RIB WAS ONLY WELDED ON ONE SIDE OF RIB.  IF WELDED ON BOTH SIDES, IT MAY HAVE NOT BROKEN LOOSE.  IF THE RIB WOULD STICK UNDER FUEL GAUGE, FLOAT COULD INDICATE MORE FUEL THAN WAS IN TANK.
