## Discrepancy

SHORTLY AFTER TAKEOFF OF A CREW TRAINING FLIGHT, THE CREW REPORTED SMOKE IN CABIN.  DIVERTED BACK TO DEPARTURE AIRPORT, LANDING SAFELY BUT DID NOT DECLARE EMER.  THIS IS THE SECOND TIME THIS ACFT REPORTED SMOKE IN CABIN IN RECENT FLIGHTS.  MX WAS DISPATCHED TO ACFT & COMMENCED TO TROUBLESHOOT.  TROUBLESHOOTING REVEALED THAT THE NR 2 ENG IS LOSING OIL INTO THE BLEED AIR SYS.  THIS REQUIRES THE ENG TO BE REMOVED & SENT IN FOR REPAIR.  TO DATE THE ENG IS BEING REMOVED SO NO FURTHER UPDATES AVAILABLE.
