The Tupolev Tu-154B entered a steep spiral dive while en route to Khabarovsk and impacted Mount Bo-Jaus, Russia, killing all 98 on board.
The aircraft operated on Khabarovsk United Air flight 3949. It took off from Yuzhno-Sakhalinsk Airport at 02:43 hours local time and climbed to the cruising altitude of 10600 meters. Shortly after 03:00 hours the aircraft suddenly banked right and entered a steep spiral dive. The flight crew was not able to regain control and the aircraft impacted terrain.
The wreckage was found 11 days later.
Probable Cause:
PROBABLE CAUSE: Fuel-feed selected from wing tanks on the left side only. This was done to counteract the tendency to fly left-wing low. The fuel imbalance caused the aircraft to bank to the right during the flight. The autopilot was able to counteract this bank until 35 minutes after take-off.
