## Discrepancy

TUNGSTEN BLOCK (BALLAST WEIGHT) AT OUTBOARD END OF LT AILERON FOUND SEPARATED FROM MAIN COUNTER WEIGHT.  BLOCK SLID FORWARD AGAINST WING REAR BEAM AND WAS RESTRICTING AILERON DOWNWARD MOVEMENT.  PROBABLE CAUSE:  LOOSE AND MISSING HARDWARE.  ONE SCREW AND TWO NUTS FOUND RESTING ON LOWER REAR WING BEAM.
