Circumstances:
After takeoff from Tompo, en route to Topolinoye, the engine emitted a thick white smoke then failed. The crew elected to make an emergency landing when the left main gear collided with rocks on the bank of the Tompo River. Our of control, the aircraft cartwheeled and crashed. All five occupants were rescued, two of them were injured, including the copilot.
Probable cause:
The exact cause of the engine failure could not be determined with certainty. However, it is believed that the carburetor got frosted after the crew forgot to activate the engine anti-ice system. Analyzes of the engine showed marks on the forward part of the compressor blades, indicating splinters of ice resulting from icing conditions.
