Circumstances:
The aircraft departed Kiev-Gostomel Airport to assist the crew of the first AN-70 prototype in its test flight. The goal of the flight was to test the stability and controllability of the airplane for the certification program. While cruising at an altitude of 3,200 metres, the crew of the AN-70 elected to approach the AN-72 but misjudged the distance, causing both airplanes to collided. The tail of the AN-70 struck the fuselage of the AN-72. The crew of the AN-72 was able to return to Kiev-Gostomel Airport and to complete a safe landing. All crew members were uninjured but the aircraft was damaged beyond repair due to severe structural damages. Upon impact, the AN-70 lost its left stabiliser and also a part of the tail. Out of control, it entered a dive and crashed in a wooded area located in Veliky Lis, about 45 km northwest of Kiev-Gostomel Airport. All seven occupants were killed.
Probable cause:
It was determined that the collision was the consequence of errors on part of the AN-70 crew who misjudged the distance between both aircraft and initiated a hazardous maneuver without knowing the exact position of the second aircraft. The following contributing factors were reported:
- The collision occurred while both aircraft were facing sun,
- Both crew did not use appropriate radio communications,
- Loss of situational awareness,
- Loss of the left horizontal stabiliser as well as part of the tail, failure of all four hydraulic systems, loss of controllability.

Circumstances:
The aircraft, first prototype of this model AN-70, departed Kiev-Gostomel Airport on a test flight with seven crew members on board. The goal of the flight was to test the stability and controllability of the airplane for the certification program. An Antonov AN-72 registered UR-72966 and also operated by Antonov Design Bureau departed the same airport to take part to the same control flight. While cruising at an altitude of 3,200 metres, the crew of the AN-70 elected to approach the AN-72 but misjudged the distance, causing both airplanes to collided. The tail of the AN-70 struck the fuselage of the AN-72. The crew of the AN-72 was able to return to Kiev-Gostomel Airport and to complete a safe landing.

Crash of an Antonov AN-124-100 in Kodra: 8 killed

Circumstances:
The aircraft departed Kiev-Gostomel Airport on a test flight part of a certification programme, carrying nine crew members. While cruising at an altitude of 19,000 feet and at a speed of 614 km/h, the radome disintegrated. This caused the front cargo door to open and to detach. Debris struck the engine n°3 that stopped automatically. The aircraft suffered strong vibrations and oscillations then the 3rd hydraulic system failed as well as the flight management system. In such conditions, the crew was unable to get valid data about speed, altitude or the angle of attack. The aircraft entered an uncontrolled descent during which flaps were selected down to reduce the speed, but due to an asymmetrical release of flaps, the descent rate increased until the aircraft crashed in a wooded area located 1,5 km south of Korda and 43 km west of Gostomel Airport. The aircraft was destroyed and eight occupants were killed. The engineer survived after he bailed out during the descent but was seriously injured.
Probable cause:
Loss of control following the in-flight disintegration of the radome and the subsequent failure and detachment of the front cargo door. The exact cause of the radome disintegration could not be determined but the assumption of a bird strike could not be ruled out.

Circumstances:
The aircraft was completing a cargo flight from Batumi to Kiev, carrying 12 passengers, five crew members and a load of mandarins. While cruising at an altitude of 4,150 meters, the captain asked the copilot to activate the deicing systems. For unknown reasons, the copilot mistakenly shut down all four engines. Following various mistakes, the crew was unable to restart the engines. The captain declared an emergency and was cleared to divert to Kiev-Borispol Airport for an emergency landing. Unable to maintain a safe altitude, he eventually attempted an emergency landing when the aircraft crashed in an open field located about 12 km northwest of Borispol Airport. All 17 occupants were rescued, among them 14 people were injured. The aircraft was destroyed.
Probable cause:
The accident was the consequence of the combination of the following factors:
- The copilot mistakenly shut down all four engine in flight,
- The crew was unable to restart the engine due to uncoordinated hasty actions in a difficult situation,
- The copilot did not have sufficient experience on this type of aircraft and was not familiar with its operation,
- Lack of crew training.

Circumstances:
The crew (pilots, technicians and engineers) were involved in a local test flight at Kiev-Gostomel Airport. The goal of the mission was to test the JATO propulsion system in case of an engine failure on the Antonov AN-8. For this test program, the aircraft was renamed AN-8RU version. Twenty seconds after takeoff, while climbing to a speed of 220 km/h, the JATO system was ignited. Six seconds later, once the speed of 264 km/h was reached, the left engine was voluntarily shut down. At this time, the crew was unable to feather the propeller that went into auto-rotation. The airplane banked left to a 70-80° angle then dove into the ground and crashed in a field located 1,850 meters past the runway end. The aircraft was totally destroyed and all seven crew members were killed.
Probable cause:
The exact cause of the accident could not be determined with certainty. However, the crew encountered difficulties, was unable to and/or forgot to feather the propeller on the left engine. This caused an asymmetric thrust and high drag which caused the aircraft to be uncontrollable and to crash.
