Incident at 100 NM NW WINNIPEG, MB

Summary

1996-08-02: Air Canada 191, an Airbus A320, was en route from Winnipeg to Saskatoon when the ECAM indicated an aileron servo fault message. The flight returned to Winnipeg where maintenance found that the message resulted from a disagreement between the aircraft's two ELAC (elevator-aileron computer) units. Maintenance disabled one ELAC and dispatched the aircraft to Saskatoon in accordance with the MEL. The aircraft was subsequently flown to Toronto, where maintenance found that the F/O's joystick had a "noisy" potentiometer, which led to the disagreement between the two ELAC units. The joystick was replaced. The operator is upgrading the ELAC system to be more tolerant of noisy joysticks.
