Category: Accident
A Tu-154 aircraft experienced a significant descent during approach to Noril’sk, resulting in a ground impact. The aircraft’s high descent speed, maximum forward center of gravity, and slow flying speed contributed to the incident. The impact occurred in an open field, and the aircraft slid across the frozen ground.A Tu-154 aircraft experienced a significant descent during approach to Noril’sk, resulting in a ground impact.

Description
While on approach to Noril’sk, the plane acquired an excessive vertical speed and descended below the glideslope. It impacted terrain in an open field about 470 m from the runway threshold and slid across the frozen ground for about 300 m. The Tu-154 had a high descent speed, maximum forward centre of gravity and slow flying speed. The high descent speed could not be countered by applying maximum elevator trim.
