## Discrepancy

ALL INDICATIONS ON THE CAPTAINS SIDE RETURNED.  THE AIRCRAFT LANDED WITHOUT INCIDENT AT THE DESTINATION.  THE AIRCRAFT WAS REMOVED FROM SERVICE.  DRAINED PITOT LINE NR 1 AND CLEARED WITH NITROGEN IAW EMB-145 AMM 34-13-00.  REMOVED AND REPLACED THE NR 1 PITOT HOSE.  THE LEAKAGE CHECK WAS GOOD.  THE AIRCRAFT WAS RETURNED TO SERVICE.
