## Discrepancy

CRACKS FOUND IN BOTH NUMBER ONE AND TWO LEFT AND RIGHT SIDE MAIN ENTRY DOOR (MED) HANDLE BOXES.  THE CRACKS EMANATE FROM THE 0.322 INCH DIAMETER HOLES NEAR THE CENTER OF THE HANDLE BOX ASSEMBLIES COMMON TO THE BASKET CAM ASSEMBLIES.  *S/D*  CRACKS CAUSED BY STRESS CORROSION OF THE MAGNESIUM HANDLE BOX MATERIAL AT INSERT LOCATIONS.  REPLACED WITH HANDLE BOX OF IMPROVED ALLOY PER IPC.
