A321 captain discovers during preflight that the aircraft had a elac 1 pitch fault and elac 2 pitch fault a day earlier and that it is the same aircraft that he experienced the same problem several weeks earlier. The maintenance sign off was ground test ok; but a detailed review of the previous flight control failures was conducted at the reporters suggestion and the pitch trim actuator was replaced.

Narrative:
During preflight fdml review; I noted that this aircraft had an elac 1 pitch fault and elac 2 pitch fault the day before. There was a maintenance sign off with a computer system/bite with no faults noted. This is the same aircraft in which I had a simultaneous F/control elac 1 pitch and F/control elac 2 pitch fault [several weeks ago] at FL350. The maintenance sign off was grn scan test of escs and bite check ok. After the problem; I was very concerned that; after the loss of primary and secondary pitch control; the link which caused these two simultaneous flight control failures was never identified. I contacted my dispatcher who placed me in contact with maintenance control. After a discussion; a detailed review of the previous flight control failures was conducted. The pitch trim actuator was replaced and all tests were completed. An uneventful flight followed. I would suggest a more comprehensive review of maintenance history anytime there is a flight control problem on any of our aircraft.
