## Discrepancy

DURING FLIGHT BOTH CREW MEMBERS HEARD A LOUD STATIC SOUND OVER HEADSETS AND HAD SMELLED A FAINT ELECTRICAL SMELL.  THE INSTANTANEOUS VERTICAL SPEED INDICATOR (IVSI) INDICATED A LOSS OF THE TRAFFIC ALERT AND COLLISION AVOIDANCE SYSTEM.  WHEN THE TCAS CIRCUIT BREAKER WAS PULLED THE ODOR AND NOISE DISSIPATED.  MAINTENANCE ISSUED MEL 34-53-2 FOR THE TCAS SYSTEM.  ON FEBRUARY 27, 2006  THE TCAS PROCESSOR WAS REPLACED.  THE AIRCRAFT WAS RETURNED TO SERVICE AFTER SATISFACTORY OPERATIONAL CHECKS WERE PERFORMED.
