The conclusions:
Russians made serious mistakes which could be of certain importance.
Polish mistakes were crushing, though, and directly contributed to 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 go-around);
