As noted in the
NAS Daily, a document deluge was given out. From Simon's avherald amendment
http://avherald.com/h?article=4c497c3c/0000&opt=0, I found this interesting and sad:
On Dec 19th 2019 the NTSB opened their public docket, no preliminary report was released so far.
Editorial notes: Information is spread over a flurry of different group reports and data files. It is thus very difficult to work out what might have contributed to the crash. There is one shout in the CVR transcript, that stands out and does not fit the scenario the aircraft performance study paints. The FO exclaims: "12:38:45.9 CAM-2 (where's) my speed my speed [Spoken in elevated voice.]" What does this mean? Did he lose the speed indication? Did his speed indication go outside the flight envelope prompting the following "stall" calls? Did the first officer refer to his feel rather than the instruments when he called the stall? And why would the captain also provide nose down inputs if his instruments were good just with the first officer shouting, or were the fligt controls still connected with the first officer pushing both yokes forward? But then, why would the captain still provide nose down inputs on the left hand elevator, though to a less extent than the first officer, after the elevators split? How did the Go Around Mode activate? What role played the apparent ADI/HSI failure and the EFIS Switch mentioned by the First Officer, was the switch indeed moved and the indications returned to normal, or was the switch not moved and the first officer saw erroneous data on his ADI/HSI? In summary, the docket does not yet provide any clear indication of all the facts leading to the crash.
In the operational factors/human performance report the chairman reports the captain (60, ATPL, 11,172 hours total, 1,252 hours on type) was pilot mpnitoring, the first officer (44, ATPL, 5,073 hours total, 520 hours on type) was pilot flying.
In the ACARS report no messages indicating system failures were contained. The report closes with a message of dispatch to the crew asking "PLS COFIRM STATUS....R U OK".
The flight data recorder group presented the table of raw flight data, however, did not provide any interpretation or graphical representation of the data.
The cockpit voice recorder group provided a transcipt, the last decisive minute reads (-1 captain, -2 first officer, -3 observer, HOT flight crew audio panel voice or sound source, CAM Cockpit Area Microphone voice or sound source, RDO Radio transmission from the aircraft, APR transmission from Houston Approach):
