Pax on board:
On the leg from Karaganda to Rostov-on-Don of a flight from Almaty to Simferopol when probably the autopilot system failed while the aircraft was flying at a height of 7,800 metres by night. The aircraft banked to the left, entered a dive and was recovered by the crew at a height of some 5,000 metres. The crew managed to land safely at Rostov-on-Don, but the aircraft suffered structural damage during the dive with up to 3.5 g forces, and was damaged beyond repair. There were no casualties. SOC 29sep71 as worn out.
Loss of control in flight caused by a probable failure of the autopilot system.
