Incident Overview
An aircraft arriving at Ürümqi-Diwopu Airport experienced a runway overrun after landing on a snow-covered runway. The approach was conducted in poor weather with snowfall.
Sequence of Events
The descent toward the airport was begun under deteriorating conditions. On final approach, the crew maintained a glide path that was too high, causing the aircraft to touch down considerably beyond the normal landing zone. After touchdown, the available runway length was insufficient to bring the aircraft to a stop. The airplane overran the runway end and came to rest a short distance beyond. The aircraft sustained severe damage and was destroyed. All five individuals on board—the entire crew—were slightly injured.
Probable Cause
According to the official investigation, the probable cause was wrong approach configuration by the crew, who attempted to land while the aircraft was too high on the glide. The findings state that because the approach configuration was non-compliant, the crew should have initiated a go-around maneuver.
