Whilst the preliminary report has not yet been released Aviation Herald reports the following:
On Dec 21st 2013 Mozambique's Civil Aviation Authority reported in a press conference that the cockpit voice recorder and flight data recorder revealed that the captain was alone on the flight deck at the time of the acident. Banging on the flight deck door could be heard on the cockpit voice recorder. The autoflight systems (autothrottle and autopilot) were engaged. There were sounds and clicks consistent with a person knowledgeable of the aircraft systems commanding the engines to idle thrust and selecting the autoflight systems into a descent at 6000 feet per minute. Numerous warnings and alerts were not responded to.
