Mas info mas objetiva sobre la cause del accidente.
On Dec 1st 2015 Indonesia's NTSC released their final report concluding the causes of the crash were:
Contributing factors
The cracking of a solder joint of both channel A and B resulted in loss of electrical continuity and led to RTLU (rudder travel limiter unit) failure. The existing maintenance data analysis led to unresolved repetitive faults occurring with shorter intervals. The same fault occurred 4 times during the flight.
The flight crew action to the first 3 faults in accordance with the ECAM messages. Following the fourth fault, the FDR recorded different signatures that were similar to the FAC CB‟s being reset resulting in electrical interruption to the FAC‟s.
The electrical interruption to the FAC caused the autopilot to disengage and the flight control logic to change from Normal Law to Alternate Law, the rudder deflecting 2° to the left resulting the aircraft rolling up to 54° angle of bank.
Subsequent flight crew action leading to inability to control the aircraft in the Alternate Law resulted in the aircraft departing from the normal flight envelope and entering prolonged stall condition that was beyond the capability of the flight crew to recover.

La falla principal entiendo se da por un problema de mantenimiento, humano para variar, y se habla de la no habilidad para controlar el avion o volarlo por parte de los pilotos.
De forma personal, creo que sigue siendo el problema que ha existido siempre entre el piloto y la automatizacion........ Como parte de la causa del accidente.
