## Discrepancy

FLIGHT 2135, AFTER TAKEOFF A STRONG SULFUR ODOR WENT THROUGH AIRCRAFT.  AFTER ABOUT 10 MINUTES ODOR DISSIPATED.  F/A REPORTED STRONG VIBRATION UNDER ROW 2.  WHEN RECIRCULATION FAN TURNED OFF VIBRATION DID NOT GO AWAY.  MAINTENANCE ISOLATED ODOR TO NR 2 A/C PACK.  MAINTENANCE REPLACED THE RIGHT AIR CYCLE MACHINE. OPS AND LEAK CHECKED OKAY.
