What happened
Shortly after departing from Lanzhou-Zhongshan Airport, the flight encountered hazardous weather characterized by intense icing. During this period, the right engine ceased functioning, prompting the crew to feather the propeller of the affected engine. Following instructions to return to the airfield, the flight crew began a descent procedure.
During the descent, the aircraft experienced a total loss of control. The plane impacted a field situated a few kilometers from the airport approximately 30 minutes after its initial takeoff. The impact resulted in the destruction of the aircraft. The accident resulted in 6 fatalities and left 38 injuries among those on board.
Findings
Investigations determined that the primary factor leading to the engine failure was severe icing conditions affecting the right engine.
