Aircraft Collision with Terrain During Approach to Tiksi (RF-91821)

Incident Overview and Flight Details A four-engine aircraft departed Yekaterinburg for Tiksi, with an intermediate stop scheduled in Kansk. The flight carried 32 passengers and seven crew members. During the approach to Tiksi, the aircraft encountered conditions associated with a polar night. The source does not specify the aircraft type, registration, operator, or exact date of the incident. ## Approach Deviation and Terrain Impact While executing the approach, the aircraft deviated from the established approach pattern and descended below the glide path. The source attributes this deviation to reliance on a flawed approach scheme. The aircraft's belly made contact with the summit of a snow-covered hill, which was 392 metres high and located 31 kilometres northwest of Tiksi Airport. Following the initial impact, the aircraft bounced and made a second contact with the ground on the rear slope of the hill, approximately 1,250 metres further along. ## Damage and Casualties The impact caused the fuselage to break into three parts. No fire occurred after the collision. All seven crew members and 31 passengers were injured, with 16 of those injuries classified as serious. The source does not provide a formal probable cause determination beyond the stated reliance on a flawed approach scheme and the resulting deviation from the approach pattern.
