## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED AND THE AIRCRAFT DIVERTED TO LIT DUE TO THE FLIGHT CREW REPORTING THAT WHILE CRUISING AT FL 340 FLIGHT ATTENDANTS ADVISED THE FLIGHT DECK THAT THERE WAS A STRONG ODOR OF SMOKE THAT WAS GETTING WORSE AND THEY PERCEIVED THAT THERE WAS AN ACTIVE UNKNOWN ORIGIN FIRE. THE AREA OF CONCERN WAS AROUND THE MID LAVATORY AREA. THE AIRCRAFT LANDED SAFELY AT LIT WITHOUT FURTHER INCIDENT.   MAINTENANCE ACCOMPLISHED SMOKE/ODOR /FUME TROUBLE SHOOTING TASK CARD 26L00021001 WITH NO FINDINGS NOTED AND NO SPECIFIC PART WAS IDENTIFIED THAT WOULD HAVE CAUSED THE ODOR.
