That sums it up nicely, everything else is noise and chaff.
Final Report Committee
3.2. Cause and Circumstances of the Accident
3.2.1. Cause of Accident
The immediate cause of the accident was the descent below the minimum descent altitude at an excessive rate of descent in weather conditions which prevented visual contact with the ground, as well as a delayed execution of the go-around procedure. Those circumstances led to an impact on a terrain obstacle resulting in separation of a part of the left wing with aileron and consequently to the loss of aircraft control and eventual ground impact.
3.2.2. Circumstances Contributing to the Accident
1) Failure to monitor altitude by means of a pressure altimeter during a non-precision approach;
2) failure by the crew to respond to the PULL UP warning generated by the TAWS;
3) attempt to execute the go-around maneuver under the control of ABSU (automatic goaround);
4) Approach Control confirming to the crew the correct position of the airplane in relation to the RWY threshold, glide slope, and course which might have affirmed the crew's belief that the approach was proceeding correctly although the airplane was actually outside the permissible deviation margin;
5) failure by LZC to inform the crew about descending below the glide slope and delayed issuance of the level-out command;
6) incorrect training of the Tu-154M flight crews in the 36 Regiment.
