An aircraft on approach to Norilsk-Nezhdanny Airport struck a mountain after an inexperienced air traffic controller permitted a descent below terrain elevation. Seven crew members died; one survivor sustained serious injuries.

Incident Overview

An aircraft operating a flight from Klin to Norilsk-Nezhdanny Airport was on final approach when it collided with a mountain top near the Talnashki River. The impact occurred at an elevation of 633 meters, and the wreckage fell into a gorge. The aircraft was destroyed.

Casualties

Seven crew members were killed in the accident. The sole survivor, the tail gunner, was seriously injured.

Air Traffic Control Involvement
