Quote:
The next phase of the investigation will further interrogate the aircraft's primary flight control computer and two secondary computers. The ATSB had identified problems with the secondary computers' ability to action commands sent from the primary. The investigation will examine the computers' software development cycle, such as design, hazard analysis, testing and certification.
The US manufacturer of the ADIRU units, not disclosed in the report, is also conducting a theoretical analysis of the device's software and hardware to identify possible fault origins, the ATSB said.
