## Discrepancy

ON INITIAL CLIMB MIS-COMPARE CAS MESSAGE ILLUMINATED. SIC INSTRUMENTS WERE INCORRECT WHEN COMPARED TO STANDBY SYSTEM. AN EMERGENCY WAS DECLARED AND AIRCRAFT RETURN TO DEPARTURE AIRPORT. MAINTENANCE REPLACED THE PITOT/STATIC SYSTEM ISOLATION VALVE. A SUCCESSFUL OPERATIONAL CHECK FLIGHT WAS PERFORMED WITH NO DEFECTS NOTED. AIRCRAFT WAS RETURNED TO SERVICE.
