Circumstances:
The airplane was engaged in a geological support mission. While approaching Yessey Airstrip, during a fourth turn, the pilot-in-command elected to correct the roll but his reaction increased the roll to an angle of 45°. The airplane lost height and crashed on the icy Yessey lake about 5 km from the village. There were no casualties.
Probable cause:
Inappropriate roll correction from the pilot on approach caused the aircraft to bank excessively, to lose height and to crash.
