The approach to Varna Airport was completed in poor weather conditions with a limited visibility due to heavy rain falls. The aircraft landed too far down a wet runway 27 and was unable to stop within the remaining distance. It overran, lost its nose gear and came to rest. All 134 occupants, most of them Swedish tourists, were evacuated safely, nevertheless several passengers suffered minor injuries. The aircraft was written off.

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:
The aircraft was completing a cargo flight from Warsaw to Beirut with an intermediate stop in Varna, carrying a crew of nine and a load of frozen meat. While approaching Beirut at an altitude of 2,100 feet, the four engine airplane struck power cables and crashed on rocky terraces located 8 km from runway 21 threshold. The aircraft disintegrated on impact and all nine occupants were killed. It was reported that ATC transmitted several instructions to the crew that failed to respond, maybe due to language issues.

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.
