General Maintenance Action
Aircraft; Procedure
SEC2 fault deferral.  This deferral must be re-evaluated. Taking off with a known flight control loss; particularly the elevator control computer; is unsafe.  I refused the aircraft.  [Maintenance] called me back to advise me that [they] didn't have an SEC and the repair was scheduled that evening in [a down line station].  I regret accepting the aircraft.  I endangered my passengers and crew by flying three legs without SEC2. I even volunteered to extend beyond my FAR117 duty limit just to get the jet to [the down line station] to let maintenance repair the SEC.
A320 Captain reported his aircraft was dispatched with SEC2 (a flight control computer) fault deferred; and expressed concern about the safety of this procedure.
