## Discrepancy

(CAN) PROPELLER RECEIVED FOR CORROSION INSPECTION. THE FOLLOWING PARTS WERE FOUND CORRODED: 2 BEARING SETS; 2 ACTUATING PINS; 2 PISTON PINS; 1 CYLINDER; 80 BALL BEARINGS AND ALL PROPELLER INTERNAL PARTS. THE SUBMITTER SUGGESTS THIS CORROSION WOULD HAVE CAUSED A FAILURE IN A VERY SHORT TIME.
