## Discrepancy

CREW FOUND LT ENGINE OIL LEAK ON PORT FLIGHT INSPECTION.  MECHANIC FOUND INTAKE BALANCE TUBE FLEX HOSE DATA TAG CHAFING ON OIL PAN.  MECHANIC REMOVED AND REPLACED OIL PAN AND FLEX HOSE AND RETURNED AIRCRAFT TO SERVICE.  FLEX LINE LENGTH WAS SHORTENED BY MANUFACTURER, CAUSING INADEQUATE CLEARANCE WHEN ROUTING HOSE.  SUGGEST RETURNING TO ORIGINAL LENGTH HOSE FOR PROPER CLEARANCE.
