Incident Overview
On approach to Kunming-Wujiaba Airport's runway 03, the crew completed the landing in poor weather conditions with heavy rainfall. The approach was conducted with an incorrect configuration, leading to an excessive landing speed of 170 knots. The aircraft touched down 2,500 feet beyond the runway threshold. Due to the wet runway surface, the aircraft was unable to stop within the remaining distance and overran the runway.
Sequence of Events
After overrunning, the aircraft struck approach lights and the ILS antenna, resulting in the loss of its nose gear before coming to rest. All 148 occupants on board were evacuated following the incident. Among them, 15 passengers sustained minor injuries. The aircraft itself was damaged beyond repair.
Probable Cause and Contributing Factors
The official investigation determined the probable cause to be a wrong approach configuration on the part of the crew, who completed the approach while too high on the glidepath. The following contributing factors were identified:
- Poor crew coordination
- Failure to follow the approach and landing checklist
- Failure to check instruments during the approach
- Unstable approach condition
- Poor weather conditions
- Wet runway surface with reduced braking action
- Excessive approach and landing speed (50 knots above standard)
- Landing too far down the runway (2,500 feet past the threshold), reducing available landing distance
- Failure to initiate a go-around procedure
