## Discrepancy

AFTER LANDING FROM A ROUTINE COMPANY FLIGHT, THE MAINTENANCE ENGINEER NOTED MORE THAN NORMAL OIL ON THE LT REAR COWLING.  UPON FURTHER INVESTIGATION, A 3 INCH CRACK WAS DETECTED ON THE CRANKCASE HALF STARTING FROM THE ENGINE DRIVEN FUEL PUMP BOSS TO THE CRANKCASE THRU BOLT.  THE ENGINE IS BEING REMOVED AND SENT TO AUTHORIZED REPAIR SHOP FOR REPAIR.
