bonajet,
nothing was wrong with the flight controls in that incident. the a/c came back to FRA with one ELAC inop (according to MEL you can conduct a flight with this handicap...). At FRA a troubleshooting was conducted and in the process they found one pin on the sidestick connector bend. therefore the connector was replaced, rewiring a new connector according to the respective (in this case 'wrong') wiring list.
The controls were then checked inside the cockpit with the ECAM indications and found okay. nobody had reason to believe that actually there was a problem with the ailerons. No work was performed there.
does this clarify it a bit?
