## Discrepancy

DISCOVERED HEAVY STAIN AT FLANGE END OF INDUCTION TUBE DURING ROUTINE OIL CHANGE.  REMOVED FLANGE RETAINER AND FOUND PIPE CRACKED APPROXIMATELY ONE-HALF DIAMETER.  CONTINENTAL HAS RECENTLY ISSUED SB 98-8 WHICH RECOMMENDED REPLACEMENT OF ONE-PIECE PIPES FOR CYLINDERS NR 1 AND NR 3.  THIS PIPE WAS FOR CYLINDER NR 4.  SUBMITTER RECOMMENDED REPLACEMENT OF CYLINDERS NR 2 AND NR 4 PIPES WITH 2-PIECE STYLE AS WELL.  LENGTH OF PIPE IS TOO MUCH FOR FLANGE STRENGTH.
