## Discrepancy

DURING CRUISE, F/A REPORTED A LOUD VIBRATION NOISE BETWEEN ROWS 1 AND 4.  NOISE COULD NOT BE HEARD IN COCKPIT.  CAPTAIN MADE DECISION TO DIVERT AND DECLARED AN EMERGENCY.  LANDED WITHOUT INCIDENT. MX FOUND THE RT AIR DUCT B WAS DELAMINATED AND THE RAM AIR DUCT C HAD A BROKEN FLANGE. MX REPLACED THE NACA BOOT AND DUCT IAW AMM AND OPS CHECKED GOOD.
