In-flight loss of control resulting in aircraft hull loss (CCCP-70908)

What happened

During the flight, the aircraft experienced a sudden loss of control. This instability led to an uncontrolled descent, ultimately causing the plane to impact a field. While the crash resulted in no fatalities, the impact caused extensive damage to the airframe, rendering the aircraft a total loss.

Findings

Investigations into the accident determined that the primary reason for the loss of control was a mechanical failure. Specifically, the investigation identified the failure of a slat control cable as the critical factor that prevented the crew from maintaining stable flight.
