## Discrepancy

DURING DESCENT THE RADAR SCREEN FLARED BRIGHTLY, THE RADAR TCAS DISPLAY WENT OUT.  SHORTLY AFTERWARD A STRONG ELECTRICAL SMELL WAS NOTICED.  THE RADAR AND TCAS WERE TURNED OFF AND ASSOCIATED CIRCUIT BREAKERS WERE PULLED.  THE SMELL DISSIPATED WITHIN A FEW MINUTES.  THE AC MADE AN UNEVENTFUL LANDING.  REMOVED AND REPLACED RADAR INDICATOR.  INSPECTED ASSOCIATED WIRING AND RESET CIRCUIT BREAKERS.  OPS CHECK GOOD.  AC WAS RETURNED TO SERVICE. (K)
