## Discrepancy

(CAN) PROPELLER RECEIVED FOR CORROSION INSPECTION. THE HUB BLADE SOCKET WAS FOUND CRACKED IN THE THREADS IN TWO LOCATIONS. THE CRACKS WERE DETECTED BY EDDY CURRENT NDT. THIS METHOD IS NOT A REQUIRED PROCESS FOR CORROSION INSPECTION. THE NDT INSPECTION IS PERFORMED AS A COMPANY POLICY.
