Moscow-Sheremetyevo, RussiaTakeoff (climb)

On March 9, 2000, a Yakovlev Yak-40 (registration RA-88170) operated by Vologda Air Enterprise - Vologodskoe Aviapredpriatie was involved in an aviation accident near Moscow-Sheremetyevo, Russia during takeoff. 9 people were killed. Investigators recorded the probable cause as: The aircraft stalled during takeoff due to aerodynamic contamination from frost and improper flap configuration following an expedited departure. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A).

A flight departing from Moscow Airport crashed shortly after takeoff, resulting in the deaths of all nine people on board.

What happened

Following a delay caused by late passengers, the crew attempted to expedite the departure from Moscow Airport to maintain their scheduled slot. During the takeoff roll, the landing gear was retracted immediately after leaving the ground. While climbing at a speed of 230 km/h and an altitude of approximately 15 metres, the aircraft type experienced a severe left roll of 65 degrees. The impact occurred roughly 1,200 metres from the runway departure point. The force of the crash resulted in the total destruction of the aircraft, though no post-crash fire was reported. There were nine fatalities among the occupants.

Findings

Investigations into the accident identified several critical factors that led to an aerodynamic stall. Although the crew had manually cleared snow from the airframe, the aircraft had not undergone a formal deicing process, leaving frost on the wings and other vital surfaces. This contamination, combined with improper configuration of the flight controls—specifically flaps set at 11° instead of the required 20° and incorrect elevator positioning—prevented sufficient lift. The accident was further compounded by inadequate flight preparation and the decision to initiate rotation at an insufficient airspeed.

Probable cause

The aircraft stalled during takeoff due to aerodynamic contamination from frost and improper flap configuration following an expedited departure.
