A captain and copilot report about their A320 being dispatched with the right wing anti-ice valve de...

Narrative:

Aircraft was dispatched from ZZZ1 in moderate icing conditions with the right wing anti-ice valve deferred. Maintenance in ZZZ deferred the valve by locking it open. Following MEL and ECAM procedures still left the aircraft with hot bleed air being sent into the right wing leading edge through the wired 'open' wing anti-ice valve. My copilot and I were not comfortable flying for an extended period of time with a known bleed air leak on the right wing. Based on our experience we decided the safest course of action was to treat this maintenance condition as a bleed air leak. After takeoff and climbout from ZZZ1; in moderate icing conditions; where we used wing anti-ice ['on' for] both bleed valves; we isolated the right wing. Number 2 bleed - off; cross bleed valve -closed; and pack 2 -off (although it would be off anyway with no bleed air on the right wing). We flew to ZZZ2 at FL310 (single pack altitude) and we added fuel in ZZZ1 to account for the lower altitude. I feel that the MEL should be readdressed to determine the danger of flying around with a manufactured bleed air leak and just allowing the bleed monitoring computer (bmcs) to monitor and detect an overheat after the damage has already been done. A bleed air leak is one of the most dangerous emergencies that can occur and could possibly lead to a wing fire. I feel that we operated the aircraft in the safest way possible with the right wing anti-ice valve wired open.

A bleed air leak is one of the most dangerous emergencies that can occur and could possibly lead to a wing fire.
