## Discrepancy

AFTER LEVELING OFF AT FL 260 & COMMENCING THE CRUISE PHASE OF FLIGHT,  PAXS REPORTED A BURNING SMELL POSSIBLY COMING FROM THE VENTS IN THE CABIN.  AT THE SAME TIME THE, RT BLEED FAIL, ANNUNCIATOR LIGHT ILLUMINATED.  AN EMER LANDING WAS DECLARED & THE ACFT RETURNED WITHOUT INCIDENT.  TROUBLE SHOT & FOUND A SEPARATED DUCT ON THE FLAPPER VLV ASSEMBLY UNDER CABIN FLOOR.  THE HEAT FROM THE SEPARATED DUCT CAUSED THE BLEED SENSE LINE TO FAIL.  SECURED THE SEPARATED DUCT & REPLACED THE BLEED AIR SENSE LINE.  SYS OPERATIONAL CHECK WAS GOOD. ACFT WAS RETURNED TO SERVICE.
