At Sofia Airport all civil traffic had been halted because of the departure of the Bulgarian "Air Force One" Tupolev 154, carrying Bulgarian leader Todor Zhivkov. Because of a delay of this flight, the air traffic controller cleared The Hemus Air Yak-40 for takeoff, asking the crew to expedite their departure. Trying to leave in a hurry, the crew forgot to set the trim correctly. Consequently, the aircraft failed to become airborne. It overran runway 09 into a ravine of the Iskar River and burst in flames.
It appeared that the stabilizer was set in the full "Down" position, instead it was supposed to be set between 2.5-3 degrees in "the Up" position.
