## Discrepancy

(CAN) SHORTLY AFTER TAKEOFF, THE CREW OBSERVED A SMOKE INDICATION AND DECIDED TO RETURN TO THE AIRPORT.  NO EMERGENCY WAS DECLARED AND THE ACFT LANDED WITHOUT FURTHER INCIDENT.   AN INSPECTION REVEALED THAT AN OIL LEAK IN THE ENGINE COMPRESSOR HAD MIGRATED TO THE AIR CONDITIONING PACK WHICH EVENTUALLY SET OFF THE SMOKE INDICATION.
