Kharkiv-Osnova | Bureau of Aircraft Accidents Archives

The crew departed Moscow-Sheremetyevo Airport on a positioning flight to Kharkiv where some passengers should be picked up for a charter flight to Lyon. On final approach to Kharkiv-Osnova Airport runway 07, at a distance of 4,600 metres from runway threshold, the crew selected flaps down. The right flap deployed to an angle of 20° (as requested by the crew) while the left flap deployed to an angle of 6°. This asymmetry caused the aircraft to roll to the left then to enter an uncontrolled descent before it crashed on the shore of lake Komsomolsk. The aircraft disintegrated on impact and debris were found 140 metres further while the main wreckage sank in the lake, some 4,300 metres from the runway threshold and 750 metres to the left of its extended centerline. All three crew members were killed.

Probable cause:

The crew lost control of the aircraft after they selected flaps down. Investigations showed that a technical failure occurred on the flap deployment synchronization system due to the failure of a drive pinion.

Circumstances:

Following an uneventful flight from Vnukovo Airport at an altitude of 7,200 meters, the crew was cleared to approach Kharkiv-Osnova Airport and to descent to 1,500 meters. While approaching at a speed of 400-500 km/h with a rate of descent of 6 meters per second, the airplane lost its both wings, dove into the ground and crashed in a wooded area located in Rus'ka Lozova, about 25 km north of Kharkiv-Osnova Airport. The aircraft was totally destroyed and all 122 occupants were killed.

Probable cause:

It was determined that a structural failure of the center section lower panel caused the failure of both wings due to fatigue cracks. The rate of descent and the presence of atmospheric turbulences were considered as contributing factors. Investigations revealed that this portion of the aircraft could not be inspected by technicians during a maintenance process due to a faulty conception of the aircraft, thus the fatigue fractures could not be detected in time. Following this tragedy, the Antonov AN-10 would not be operated anymore in passenger service.
