Circumstances:
During the takeoff roll on runway 09 at Sofia-Vrazhdebna Airport, the three engine aircraft was unable to rotate and failed to become airborne. It overran and crashed in a ditch, bursting into flames. Eight occupants were seriously injured while 29 others were killed. The aircraft was destroyed by impact forces and a post crash fire.
Probable cause:
It was determined that the Sofia Airport should be momentarily closed to traffic because the Presidential Tupolev TU-154 of the Republic of Bulgaria was scheduled to takeoff with the Bulgarian President Todor Zhivkov on board. Large delays were expected so ATC cleared the crew to take off but asked him to expedite takeoff. In a certain confusion and in the rush, the crew failed to follow the pre-takeoff checklist and forgot to set the trim correctly. As the stabilizer was incorrectly set in the down position, the aircraft was unable to rotate and overran the runway before crashing.

Circumstances:
Following a wrong approach configuration, the four engine airplane landed too far down on runway 25 and was unable to stop within the remaining distance. It overran and came to rest. While all nine occupants escaped uninjured, the aircraft was damaged beyond repair.
Probable cause:
It was determined that the crew completed a wrong approach configuration, making a steep turn too late on final. The following contributing factors were reported:
- The aircraft' speed at touchdown was excessive,
- As the aircraft was too high on approach, it landed too far down the runway, approximately a third past the runway threshold,
- The crew failed to initiate a go-around maneuver,
- Poor crew coordination.

Probable cause:
The decision of the crew to continue the approach below the glide without any visual contact with the runway until impact with obstacles.

Circumstances:
While parked on apron at Sofia-Vrazhdebna Airport, the airplane was deiced and the snow was removed before the crew was cleared to taxi to runway 10 for takeoff. However, the runway was closed for snow removal. When this was done, the crew was cleared for takeoff and just after liftoff from runway 10, the airplane encountered difficulties to gain height, stalled and crashed on a bank of the Iskar River located by the airport. The copilot was killed and two passengers drowned. All other occupants were rescued, some of them were injured.
Probable cause:
The hold over time (HOT) between the deicing time and the takeoff time was too long and a significant amount of snow accumulated on the fuselage, wings and all critical surfaces. In such conditions, the aircraft was unable to take off. The crew failed to request a second deicing.
