The Tupolev was on a night-time approach to Irkutsk in instrument conditions when the crew were told that they were flying to the left of the extended runway centerline. An excessive turn then placed the aircraft to the right of the extended centerline. The approach was being flown at a speed some 15-20 mph below the normal approach speed with a high rate of descent. The plane was in a slight left bank when it touched down hard some 500 feet short of the runway. The left wing broke off, causing the plane to roll to the left, bursting into flames.
