## Discrepancy

DURING A 100-HOUR INSPECTION, NOTED FUEL WAS LEAKING FROM PUMP DRAIN TUBE.  OPERATION OF THE PUMP RESULTED IN A STEADY FLOW OF FUEL FROM THE DRAIN.  A CHECK OF SISTER PLAN N93AF, 17280073, PRODUCED SIMILAR DEFECT.  PUMPS ON BOTH PLANES HAVE BEEN REPLACED WITH NO FURTHER LEAKS.  A THIRD 172R WAS MENTIONED IN AN FBO AS TO HAVING THE SAME PROBLEM.
