## Discrepancy

RETURNING TO BASE AT THE COMPLETION OF A SCENE FLIGHT, THE ECS UNIT WAS TURNED ON.  AFTER A FEW MINUTES THE MEDIC, IN THE CABIN, STATED THAT THERE WAS A FOG IN THE CABIN & A STRONG SMELL OF JET FUEL.  THE PILOT BACKED UP BY THE NURSE HOLDING THE RFM RAN THE SMOKE & FUME ELIMINATION CHECKLIST.  SINCE THE PILOT SUSPECTED THE SMOKE WAS COMING IN THROUGH THE CABIN ECS DUCTING, THE PILOT TURNED OFF THE ECS.  THE AIR IMMEDIATELY CLEARED & THE SMELL OF FUEL WENT AWAY.  AS THE SHIP WAS ONLY THEN A FEW MILES FROM THE BASE, THE CREW LANDED BACK AT BASE & NOTIFIED MX.  THE PILOT INSPECTED THE NR 1 ENG COMPARTMENT & FOUND OIL LEAKING FROM BOLTS ON THE COMPRESSOR CASE.  THE MECHANIC HAD TOPPED OFF THE OIL EARLIER IN THE DAY & NOW AFTER LESS THAN AN HOUR OF FLIGHT, THE OIL LEVEL HAD DROPPED TO ADD 2 QUARTS LINE.  MX ACTIONS ARE ONGOING.
