Most probably, the accident involving S-2UT Sintal RARA-0660G single-built aircraft was caused by PIC's erroneous actions during turn maneuver that resulted in speed loss, aircraft high angles of attack and stalling mode followed by aircraft ground impact.

Probable factors contributing to the emergency situation in the air are:

- non-compliance with limitations specified by FOM of S-2UT Sintal single-built aircraft on maximum take-off weight, speed, altitude and rolling during crop-dusting operations;

- non-compliance with "Provisions on features of duty and rest-time of CA aircraft crew members of the Russian Federation", Ministry of Transport of the Russian Federation order from November 21, 2005 № 139 in part of allowed flight time during crop-dusting operation with high-toxic and toxic substances;

- stall warning system at the aircraft was inoperative from the time of its installation on aircraft board due to its incorrect assembly and couldn't give information on aircraft stalling angles approach.

The appropriate safety recommendations based on the investigation results were developed.
