## Discrepancy

AIRCRAFT WAS PULLED INTO HANGAR FOR MAINTENANCE.  TECHNICIAN NOTICED OIL RUNNING OUT OF LT ENGINE COWLING.  AFTER REMOVING COWLING, FOUND LINE FROM UNFEATHERING PUMP TO NTS/BETA SWITCH CRACKED ALL THE WAY AROUND AT THE FERREL FOR THE 'B' NUT AT THE MANIFOLD.  (THIS IS A CESSNA SUPPLIED LINE).  INSTALLED NEW LINE, GROUND RAN, LEAK CHECKED OK.  SUBMITTER SUGGESTS MANDITORY REPLACMENT AT ENGINE OVERHAUL.  LINE IS MADE OF STAINLESS STEEL TUBING.
