Circumstances:
On a night approach to Kiev-Zhuliany Airport, while initiating a fourth turn to join the approach path, the airplane struck the ground at a speed of 420 km/h, gear and flaps up. It crashed in a huge explosion in a field located 16 km west of the airport. The aircraft was totally destroyed and all 29 occupants were killed.
Probable cause:
The crew continued the approach by night without proper settings related to the atmospheric pressure. The following contributing factors were reported:
- The airfield pressure on the captain instrument 2077 was not established,
- The selected approach procedure was not established,
- The airfield pressure on altimeters was not established,
- ATC instructions to reduce the approach speed, transmitted twice, was not respected by the crew,
- The fourth turn on final was initiated too late and only following an ATC reminder.

Circumstances:
On a flight from Kiev-Borispol to Ivano-Frankivsk, the crew (who never had been at Ivano-Frankivsk before) mistook in bad visibility an agricultural airstrip located 17 km from Ivano-Frankivsk International Airport and landed there. As the runway was only 500 meters long, the aircraft overran and came to rest into a ravine, broken in two. All 65 occupants escaped unhurt while the aircraft was written off.
Probable cause:
Poor flight preparation on part of the crew who landed on the wrong airport and an inappropriate airstrip for such aircraft.

Circumstances:
En route from Ivano-Frankivsk to Uzhgorod, the crew was informed that Uzhgorod Airport was closed to traffic due to poor weather conditions and was instructed to divert to Mukachevo Airport. On approach, the crew encountered clouds and icing conditions. Cleared to descend, the crew selected flaps down to 38° when the airplane lost longitudinal stability. Shortly later, it entered a nose-down attitude and plunged at an angle of 70° and a speed of 230 km/h in an open field located 100 meters past the outer marker. The aircraft was totally destroyed and all 24 occupants were killed.
Probable cause:
It was determined that the loss of control occurred in icing conditions while the deicing systems were switched off. On approach, when the flaps were selected down, the stabilizers were covered by ice and this caused the airplane to become unstable. At an altitude of 200 meters, control was lost when the airplane entered a nose-down attitude and the distance to the ground was insufficient to expect recovery.

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.

Probable cause:
It was determined that the ailerons control cables have been incorrectly installed by the technicians from the Zavod No. 421 GA at Vinnitsa facilities. Also, the presence on board of a passenger, a young girl, was considered as illegal.

Circumstances:
The crew was engaged in a crop spraying flight (herbicides on corn field) for the sovkhoz (state farm) 'Gornyak' located in the Starobeshevo district of the Donetsk region. While flying at a height of about 50 meters, the captain made a sharp turn to the right when the airplane lost height and crashed 3,5 km west of Hirnyk. The aircraft was destroyed by a post crash fire, a pilot was killed as the second occupant was seriously injured.
Probable cause:
Error of judgment on part of the pilot-in-command who completed a sharp turn to the right while the aircraft's speed was too low, causing the airplane to stall and to crash.

After liftoff, while climbing to a height of some 10-15 metres, the airplane lost height, crashed 500 metres from its parking position, caught fire and burnt out. Both occupants were killed. The pilot had a blood alcohol level of 1.84 ‰ against 1.24 ‰ for the mechanic.
Probable cause:
Poor flight preparation on part of the pilot who failed to check the aircraft prior to departure.

Circumstances:
The single engine airplane departed Novooleksiivka Airport at 1740LT on a schedule service (flight D-44) to Kherson, carrying 17 passengers (11 adults and 6 children) and two pilots. While descending to Kherson Airport, the crew was informed by ATC about Army helicopter movements in the vicinity of the airport, on its east side. On short final, at a height of 20-30 meters, the aircraft banked right to an angle of 70° then rolled left and right. Out of control, it stalled then crashed in flames 400 meters short of runway 02 threshold. Both pilots and 12 passengers were killed while five other occupants were injured. The aircraft was destroyed.
Probable cause:
Loss of control on short final due to the presence of wake turbulences caused by an army helicopter (type Mil Mi-6) that passed through the approach path 45 seconds prior to the AN-2. It was determined that ATC clearance failed to respect the minimum safe distance and minimum safe time between both movements (minimum safe separation). It was also reported that there were two too many passengers on board and that some of them failed to wear their seatbelt.
