A Bombardier CRJ-100 aircraft operated by Air Georgian, was conducting flight GGN7272 from Memphis Intl (KMEM), TN to Toronto/Lester B. Pearson Intl (CYYZ), ON.
During the descent into CYYZ, both the captain's and co-pilot's airspeed and altitude became unreliable. The flight crew followed QRH procedures, and managed to recover the co-pilot's Flight Director (FD) and Flight Mode Annunciator (FMA). A PAN PAN was declared, and the aircraft proceeded to land using the co-pilot's instruments. ARFF was standing by for the landing. After fault verification, the operator’s maintenance replaced the number 1 Air Data Computer (ADC) and purged the pitot line. The aircraft was then returned to service.
