Aircraft Equipment Problem Critical; Deviation / Discrepancy - Procedural Published Material / Policy
General Maintenance Action
Aircraft; Procedure
About 30 minutes before departure we got Brakes System 1 Fault ECAM and notified Maintenance. They deferred Brake System 1 and we blocked out 4 minutes late after having to wait for the maintenance release. After start and before taxi we got N/W STRG Fault ECAM and I contacted Maintenance Control. He had me cycle the A/Skid and N/W STRG switch which cleared the ECAM. During the short taxi to the runway; I had to hold full left rudder or about 10 degrees left with the tiller to track the taxiway centerline. The First Officer and I both agreed that this was not acceptable and we returned to the gate. Maintenance replaced the BSCU black box which cleared the Brake System 1 deferred item and completed the autoland test to return the aircraft to CIII status. Maintenance finished the repairs and after a discussion with Dispatch about fuel for the flight we were OK with the same planned fuel and called for the fuel truck while they boarded the flight. After about 40 minutes and six calls to Operations and no fueler; but were told each time that the fueler was on the way; I called Dispatch again and raised the fuel 700 LBS to generate a new fuel request and advised him of our problems getting fuel. He said that he would advise Load Planning as they had a direct line to the fuelers. After a two hour maintenance delay this additional delay was NOT acceptable. The taxi and takeoff were normal. After landing we got Brake System 1 Fault and Steering ECAMS with some erroneous steering inputs that I corrected with differential braking and we exited the runway onto taxiway. During the rollout the Tower cleared us to cross the parallel runway but without steering I stopped short of the runway and we advised Tower of our mechanical problem and would need a tug to be towed to the gate. The First Officer contacted Maintenance and they wanted us to reset several circuit breakers which I declined after having just experienced the steering failure. I did not want to risk blocking the runway as just past the hold short line is a sharp turn that I did not want to attempt with differential braking between landing aircraft if we had another failure.
A320 Captain experiences brake and steering faults prior to departure and Maintenance replaces the BSCU. After landing at destnation the same faults return and the aircraft is towed to the gate.
