Circumstances:
The crew was completing a local training flight at Vitebsk. On approach, a technical problem occurred on the left flap that retracted. The airplane banked left then dove into the ground and crashed about 12 km from the airport. All seven crew members were killed.
Probable cause:
It was determined that a cog-wheel on the left flap broke on approach, causing an uncommanded retraction of the flap. Due to an asymmetric flaps deployment, control was lost.
