## Discrepancy

MAJOR OIL LEAK. DISCOVERED BY NURSE STOWING EQUIPMENT IN REAR COMPARTMENT. HE ADVISED ME OF OIL ALL OVER THE SIDE OF AIRCRAFT. I SHUT DOWN THE AIRCRAFT AND EXITED TO INSPECT.  REMOVED AND RE-INSTALLED OIL VENT LINE FROM TANK, GROUND RUN, LEAK CHECK WAS GOOD, REINSTALLED MAIN ROTOR BLADES, RII CHECKLIST AND OPERATIONAL CHECK FLIGHT COMPLETED.
