Per the report, pilot conversations during the critical period right before the CBs pulls were unintelligible.
The recorder showed that the FAC 1 CB was reset 54 seconds after the activation of the 4th master caution. During this period communication between the SIC and PIC recorded on the CVR was unintelligible. Assuming that during these 54 seconds both pilots discussed the plan and consequences of resetting the FAC CB, the time available would not have been sufficient. The discussion should have included a review of the CB's allowed to be reset in flight in the TDU and OEB table. The evidence of the SIC delayed action when the autopilot disengaged indicated that the SIC did not anticipate the autopilot disengagement.
