The Interstate Aviation Committee Investigation team has completed the investigation of the accident with A-22LS (FVSP) RA-1683G aircraft owned by "Siberian aerial forest protection base", Ltd occurred in the Tyumen region on August 16, 2016.

Most probably the accident with A-22LS (FVSP) RA-1683G aircraft was caused by its stall at low altitude due to speed loss during aerial protection of forest against fire by crew.

Most probably the accident was caused by combination of the following factors:

-          PIC distraction from speed monitoring during forest fire inspection;

-          descending below specified minimum safe altitude that didn't allow PIC to recover the aircraft from stall; 

-          significant turbulence caused by strong updrafts and downdrafts above fire point.   

No artificial stall warning (annunciation or aural warning) at this aircraft. 

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