Winnerhofer, it appears that you are the one allocating blame.
My rough translation identifies the following significant aspects (as DW):-
“Inappropriate response of the crew”,
“Lack of structured failure analysis",
“Not understanding the situation"
“The division of labor in the cockpit."
“Inadequate pilot training in the application of the procedure unreliable IAS."
Modern views of human behavior do not allocate blame; instead they look for underlying contributions such as an inappropriate response which often results from a failure to understand the situation (awareness and training) and selection or application of procedures (training and reliance on humans to manage complex situations).
The report also considers the underlying technical failure and infers (my view) that the operational / regulatory approvals to continue based on refresher training also contributed.
