## Discrepancy

(CAN) AFTER TAKE-OFF, THE AIRCRAFT DISPLAYED A IAS DISAGREE CAUTION LIGHT AS THE CAPTAIN`S ASI DID NOT MATCH THE CO-PILOT OR STANDBY. MAINTENANCE CARRIED OUT TROUBLESHOOTING AND FOUND A PARTIALLY BLOCKED PITOT TUBE TO BE THE CAUSE. THE PITOT TUBE WAS REPLACED AND THE AIRCRAFT RELEASED BACK INTO SERVICE.
