What happened
During an approach to Izhevsk Airport, the flight crew encountered instability with the aircraft, prompting the captain to initiate a go-around procedure. During a subsequent attempt to land a few minutes later, the aircraft experienced significant lateral oscillations, rolling left and right before developing a steep right bank. This maneuver caused the right wing to make contact with the ground.
Traveling at approximately 180 km/h, the aircraft type underwent a cartwheel motion and crashed in an open field located near the runway threshold. The accident resulted in 4 fatalities, including the copilot and three passengers, while the remaining 49 occupants sustained injuries, with several individuals suffering serious harm.
Findings
Investigations into the accident revealed that the loss of control during the final approach was triggered by a failure within the elevator control system. This failure occurred because the control wiring had become completely disconnected. The root cause was identified as improper installation and negligence during a recent maintenance overhaul performed at factory #403 in Izhevsk.
