What was found

DURING NDT INSPECTION IT WAS NOTED THAT THE BLOCKING AND RELIEF VALVE HOUSING IS CRACKED. THE HSG IS BLUE AND HAS THE PN 3321777-1 ON IT. THAT MEANS THAT IT IS IN COMPLIANCE WITH THE AD BUT IT STILL CRACKED. THIS IS THE EXACT SAME FAILURE MODE OF THE SAME COMPONENT THAT WAS REPLACED IAW AD.
