The pilot's description of the incident, as quoted by Oleksiy Sokolov on 'Mentour Pilot':
The second engine exploded and cut electric wires, so we lost all the electricity. And we returned to the aerodrome of departure on an airplane having a total electric failure. We lost all the communication, both intra-cockpit and with the ATC. We just gained 300m altitude at that point. We were a crew of 6, and other technical crew of 8, they were in the rear cabin. We took a decision to return to the aerodrome of departure, visually, we tried to establish visual communication but that didn’t work. We took a decision to land on RWY25, since it was a critical situation and we took a decision to land as soon as possible. Since we didn’t have a lot of altitude and excess of thrust too. There was a complete electric failure, brakes didn’t work, reverse didn’t work either since the wires were cut. The landing was soft, there was no damage during the touchdown, all the damage was due to the runway excursion. The gauges in the cockpit didn’t work, from the angle of attack we figured out the speed was about 280, it was a calculated airspeed. We haven’t even raised the flaps at that time, just raised the gears and we heard a bang. We still had control, but the electrical system failed completely.
