Approaching Yuzhno Sakhalinsk in instrument weather conditions, the crew requested a direct approach without completing the standard approach pattern. A premature descent was initiated and the Ilyushin impacted the wooded side of Mount Ufa (793 metres) at an elevation of 550 metres.
Flight SU721 was a scheduled service from Moscow-Sheremetyevo to Yuzhno-Sakhalinsk via Krasnoyarsk and Khabarovsk.

PROBABLE CAUSE: 1) Lack of radar availability at Yuzhno-Sakhalinsk; 2) premature descent; 3) insufficient knowledge of the approach conditions; and 4) poor in-flight planning.
