Circumstances:
On final approach to Izhevsk Airport, the aircraft became unstable and the captain decided to make a go-around. Few minutes later, on a second attempt to land, the aircraft rolled left and right than banked right, causing the right wing to struck the ground. At a speed of 180 km/h, the aircraft cartwheeled and crashed in a field near the runway threshold. The copilot and three passengers were killed while all 49 other occupants were injured, some of them seriously.
Probable cause:
It was determined that the loss of control on final approach was the consequence of the failure of the elevator control system following a complete disconnection of the control wiring. This was the result of improper installation and negligences during the last maintenance overhaul conducted at factory #403 at Izhevsk.
