Circumstances:
On 03.10.2019, the crew of An-12BK UR-CAH aircraft operated by PJSC «AIRLINE «UKRAINE-AIR ALLIANCE», consisting of flight crew members and two aircraft technicians, performed flight UKL4010 en-route Toronto (Canada) - Toulouse (France) and at 06:15 UTC, it landed at the Toulouse aerodrome (France). The plane delivered 1537 kg cargo to the Toulouse aerodrome (France). After the completion of post-flight procedures, the flight crew went to rest at the hotel, while the technicians remained on the aircraft to perform technical works. The next flight was scheduled from Toulouse to Birmingham airport (Great Britain). However, during the day, at the initiative of the operator, it was decided to change the route and perform the flight en-route Toulouse - Vigo (Spain) - Istanbul (Turkey). At the Toulouse aerodrome, the plane was filled with 6,000 liters of fuel. Also in Toulouse, a flight engineer was replaced. At 16:16 UTC, the plane took off from Toulouse to Vigo without cargo. Landing at the Vigo aerodrome (Spain) was performed on 03.10.2020 at 18:20 UTC. At the Vigo aerodrome, the plane was loaded with vehicle spare parts with a total weight of probably 14078 kg. From the Vigo aerodrome (Spain), the plane took off on 03.10.2019 at 22:20, flight UKL4050, with a delay of 2 h 20 minutes. On 04.10.2020, at 03:17:29 UTC, the plane approached the airspace border of the Lviv control area. The crew contacted the controller of the Lviv ACC of LVE + LVW sector and reported about the approach to waypoint MALBE at FL250. The controller informed the crew about the establishment of the radar identification of the aircraft and instructed to wait for the procedure for radar guidance to RW-31 using the ILS system. At 03:20:27, under instruction the ACC controller, the crew listened to the ATIS "Romeo" information as follows: “Lviv, ATIS “Romeo” for 03:20. The ILS approach at the aerodrome uses low visibility procedures. Runway in use is RW-31. Runway surface condition known at 19:53 - wet, clear. The measured friction coefficient is 0.55. Estimated surface friction assessed as good. Transition level - 110. Warning: large flocks of birds in the aerodrome area and on the landing final. There is no wind. Visibility - 150 meters; visibility range on the runway at the touchdown point - 550 meters, in the middle of the runway - 550 meters, at the end of the runway - 550 meters, fog. Vertical visibility - 50 meters. Temperature + 3ºС, dew point + 3ºС. Atmospheric pressure QNH - 1013 hectopascals, QFE - 974 hectopascals. Weather forecast for TREND landing: visibility sometimes is 400 meters, fog; vertical visibility - 60 meters. Attention: the frequency "Lviv-taxiing" does not work, while taxiing, get in touch with the "LvivTower" at a frequency of 128.0 MHz. Please acknowledge receipt of Romeo's information." ATIS information was transmitted in English. At 03:22:14, the crew informed the controller about the completion of listening to ATIS information and received clearance to descend to FL120. At 03:22:40, the aircraft began its descent from FL250 and at 03:28:35 switched to the frequency of the ACC controller of the LVT sector. After contacting the controller of the ACC of the LVT sector, the crew reported a descend to FL120 to KOKUP point. At 03:29:08, the ACC controller of the LVT sector instructed the crew to continue descending to an altitude of 10,000 feet at atmospheric pressure QNH-1013 hPa, reported the transition level, and instructed to wait for radar guidance for ILS approach on RW-31. The crew confirmed the instruction to descent to 10,000 feet, QNH, transition level and reported expectation for radar guidance. At 03:30:14, LVT sector ACC controller began radar guidance. At 03:32:49, the controller instructed the crew to descend to 4,000 feet. At 03:35:33, LVT sector ATC controller instructed to descend to an altitude of 3200 feet, taking into account the temperature correction. The procedure for temperature correction at determination of flight levels by an air traffic controller during the radar vectoring was published in the Aeronautical Information Publication of Ukraine, UKLL AD 2.24.7-1 dated 12.09.2019. At 03:38:33, the ATC controller of the LVT sector provided the crew with information about its location of 27 km from VOR/DME LIV, instructed by the left turn to take a 340º heading, cleared the ILS landing approach to runway 31 and gave the control instruction to inform of “the localizer beam capture.” At 03:40:01 (the height above the runway was 1170 m, descent rate: -4 ... -4.5 m/s, speed 352 km/h, distance from the runway threshold: 15.7 km), the crew reported of the localizer beam capture. At 03:40:09, ATC controller of LVT sector instructed the crew to continue the ILS approach to RWY 31. At 03:40:26, the controller informed the crew about the weather conditions at the aerodrome: RW-31 runway visual range (RVR) in the touchdown zone – 800 meters, in the middle of the runway – 800 meters, at the end of the runway – 750 meters, vertical visibility – 60 meters, fog. The crew confirmed receipt of the information. At 03:41:22, the ATC controller of LVT sector instructed to switch the communication to the ATC Lviv controller at a frequency of 128.0 MHz. There were no irregularities in air traffic servicing of the An-12 aircraft, flight UKL4050, during the flight in the area of responsibility of the TMA Lviv "LVT" sector. To enter the glide path, the PIC increased the vertical descent rate. At 03:41:47, the crew established communication with the Tower controller. The distance from the threshold was 11.3 km, the elevation over the glide path was 70 m, the vertical rate of descent was -5.5 ... -6 m/s. After communication with the air traffic controller, the crew reported an ILS approach to RW-31 and the atmospheric pressure QNH setting of 1013 hPa. At 03:41:58, the Tower controller informed the crew about the absence of wind on the surface of RW-31 and gave clearance to land. The crew confirmed the landing clearance. According to the recorders, at this time the distance to the touchdown point was 7.58 km, the plane was 11 m below the glide path, the vertical descent rate was -4.5-5.5 m/s, and the speed was 290 km/h, the flight heading – 315º. At a distance of 5.0 km to the touchdown point, the plane was 25 m below the glide path. At a distance of 3 km from the touchdown, the plane descended to an altitude of 105 meters and continued the flight with the constant descent. At an altitude of 60 meters, an audible alarm was triggered on board the aircraft, when the decision height had been reached, to which none of the crew members responded. At a distance of 1348 meters from the threshold of the RW-31, at an altitude of 5-7 meters, the aircraft collided with trees, fell to the ground and came to rest at a distance of 1117 meters from the runway threshold. All three passengers were seriously injured and all five crew members were killed.
Probable cause:
The most probable cause of the accident, collision of a serviceable aircraft with the ground during the landing approach in a dense fog, was the crew’s failure to perform the flight in the instrument conditions due to the probable physical excessive fatigue, which led to an unconscious descent of the aircraft below the glide path and ground impact (controlled flight into terrain).
Contributing Factors:
Probable exceeding the aircraft takeoff weight during departure from the Vigo Airport, which could result in increase in consumption of the fuel, the remainder of which did not allow to perform the flight to the alternate Boryspil aerodrome.

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. Both aircraft were totally destroyed and all 94 occupants were killed.

Circumstances:
Following a night takeoff from Lviv-Snilow Airport, while climbing, the crew encountered a major technical failure on the left engine that caught fire. The airplane went out of control and crashed in a huge explosion in Vinniki, about 12 km east of the airfield. The aircraft disintegrated on impact and all 17 occupants have been killed.
Probable cause:
It was determined that a turbine blade located on the 1st stage of the high pressure turbine of the left engine broke off shortly after rotation, due to conception failure. Analyses revealed that the turbine blade that failed had not been the subject of a standard thermic treatment, which had the effect of reducing its resistance and its hardness that was lower than the requirements of the technical specifications. Investigators stated that the turbine blade failure caused a sudden loss of power of the left engine and several debris smashed in the turbine chamber, resulting in the rupture of a fuel line. Under pressure, the fuel leaked into the chamber and ignited while contacting various elements whose temperature was high. Under such circumstances, the flight crew was unable to maintain an adequate control of the aircraft.

Circumstances:
On final approach to Lviv-Snilow Airport in icing conditions, at an altitude of 100 meters, the crew deployed the flaps at 45° when the aircraft stalled and crashed in a swampy area located short of runway threshold. A passenger was seriously injured while 32 other occupants were killed. Excessive ice accumulation on stabs caused the airplane to be unstable and to stall.
Probable cause:
Investigations were able to determine that the cause of the accident was an excessive deployment of flaps during an approach completed in icing conditions. The combination of icing conditions (excessive ice accumulation on stabs) and excessive flaps deployment caused the aircraft to stall. Following this accident, Antonov will provide an update of the flight manuals with a modification of the approach procedures, limiting the flaps deployment to an angle of 15° in icing conditions. Investigations conducted about this accident will be able to determine the cause of a similar accident that occurred at Lviv Airport on 16NOV1959, causing the crash of the same type of aircraft in identical conditions.

The airplane disintegrated on impact and all 40 occupants were killed.
Probable cause:
Loss of control in icing conditions when the flaps were downed to 45° on approach, apparently due to an excessive accumulation of ice on wings and stabs. The distance between the aircraft and the ground was insufficient to expect a recovery.

At the time of the accident, weather conditions were as follow: overcast between 100 and 200 meters, mist and a visibility estimated between 2 and 4 km. The crew departed at 0750LT on a cargo flight to Moscow via Kiev but lost almost immediately his sens of orientation while cruising southbound at an altitude of 150 meters. The pilot-in-command elected to return when the aircraft crashed on a wooded hill located 7,5 km south of the airport. All seven occupants were killed.
Probable cause:
Loss of control while flying under VFR in IMC conditions.
