Circumstances:
The four engine airplane departed Vigo Airport, Spain, at 2330LT on the evening of October 3. Following an uneventful flight, the crew initiated the descent to Lviv-Danylo Halytsky Airport when he encountered marginal weather conditions with limited visibility due to fog. On final approach to runway 31, the crew failed to realize his altitude was too low when the airplane struck the ground and crashed in bushes located about 1,500 meters short of runway threshold. Five crew members were killed while three others were injured. At the time of the accident, the horizontal visibility was about 800 meters in fog with a vertical visibility of 200 feet.

Circumstances:
The aircraft departed Moscow-Domodedovo at 1838LT on a cargo flight to Baku with an intermediate stop in Lviv, carrying five crew members and a load of various goods for a total weight of 400 kilos, among them metallic hoses. Nine minutes after takeoff, while climbing to a height of about 3,600 meters, the crew noticed discrepancies in the fuel system which resulted in a slight reduction of the fuel pressure in the fuel supply line connected to the left engine. The left part of the aircraft was visually inspected and as nothing abnormal was noted, the crew decided to continue the flight. 18 minutes later, while approaching the altitude of 7,200 meters, the crew noticed an important increase in the fuel consumption while the fuel supply system pressure dropped. An analysis of the system made it possible to detect a leak and as the crew was attempting to shut down the left engine, a fire started in the bottom of the left engine nacelle. At 1914LT, the captain informed ATC about the failure of the left engine and was cleared to return to Domodedovo Airport. Less than two minutes later, the captain reported to ATC that the left engine was on fire and requested to be vectored to the nearest airport. At that time, the nearest airport was Tula-Klokovo located 140 km from his position. Few minutes later, the left engine, engulfed by flames, detached and fell away. As the captain realized it would not be possible to reach Tula Airport, he continued the descent with a rate of descent of 100 meters per second in an attempt to land in an open field. The aircraft entered clouds and at a height of 300 meters, the pilot-in-command suffered a spatial disorientation. The aircraft nosed down by an angle of 80° and crashed at a speed of 612 km/h in a wooded area located 3,5 km northeast of Sosensky. The aircraft disintegrated on impact and all five occupants were killed.
Probable cause:
The left engine caught fire and detached after a fuel line broke in flight, causing the fuel to leak in the engine nacelle and to ignite while in contact with high temperature parts. The following contributing factors were reported:
- Failure of the crew to identify the fuel leak in time,
- Failure of the crew to abort the flight and to return to the departure airport in time,
- Failure of the crew to shut off the fuel supply system in time, which contributed to the fire development,
- Failure of the crew to follow the emergency procedures,
- Loss of control after the pilot-in-command suffered a spatial disorientation.

Circumstances:
The Antonov AN-26 departed Lviv-Sknyliv Airport at 1202LT and was climbing to 3,900 meters. En route to Moscow, it was carrying 15 people, most of them officers from the Carpathian Military contingent. While cruising in clouds at an altitude of 3,900 meters, the AN-26 collided with an Aeroflot Tupolev TU-134 registered CCCP-65856 that was descending to Lviv Airport on a flight from Tallinn with 79 people on board. Following the collision, both aircraft entered a dive and crashed in an open field located near the city of Zolochiv, about 60 km east of Lviv. Both aircraft were totally destroyed and all 94 occupants were killed.
Probable cause:
It was determined that the accident was the consequence of a poor radar coverage by ATC who failed to properly coordinate control and assistance to both planes. ATC in charge of the sector where the collision occurred cleared the crew of the TU-134 to continue to descend when he actually had no idea of the exact position of both planes. This caused the Tupolev to descend too low and to cut the Antonov trajectory. The supervisor in charge of the sector was also blamed insofar he failed to pay sufficient attention to the operations and was unable to identify in time a possible conflict and thus, was unable to initiate any corrective action and to assist his colleague.

Circumstances:
Following an uneventful flight from Tallin, the aircraft entered the TMA of Lviv and was cleared to descend from 4,800 meters to 4,200 meters. The crew was informed about the presence of an Antonov AN-26 that took off from Lviv-Sknyliv Airport at 1202LT and was climbing to 3,900 meters. En route to Moscow, the AN-26 was carrying 15 people, most of them officers from the Carpathian Military contingent. At 1212LT, the crew of the TU-134 was cleared to continue to descend below 4,200 meters. One minute later, while cruising in clouds at an altitude of 3,900 meters, both aircraft collided, entered a dive and crashed in an open field located near the city of Zolochiv, about 60 km east of Lviv.
