Description
The An-12 suffered landing gear collapse after touchdown at Batagay Airport. The aircraft operated on a cargo flight, transporting 11350 kg of cargo and two accompanying persons. After touchdown the forward axle of the right-hand main landing gear collapsed. The no.4 engine and wing tip impacted the ground and the aircraft swerved off the runway, colliding with an earthen wall. A possible reason for the failure of the axle was the long-term operation of the aircraft at low temperatures with a large number of landings at the maximum permissible landing weight and at high speeds.
