A four-engine aircraft overran runway 25 after landing too far down due to a wrong approach configuration. All nine occupants escaped uninjured, but the aircraft was damaged beyond repair.

Accident

A four-engine airplane touched down too far down on runway 25 following an incorrect approach configuration and was unable to stop within the remaining distance. It overran the runway and came to rest. The nine occupants on board evacuated without injury, but the aircraft sustained damage beyond repair.

Investigation

Investigators determined that the crew had set up a wrong approach configuration, which led to a steep turn executed too late on final approach. The aircraft's speed at touchdown was excessive, and because it was too high on approach, it landed approximately one third of the way past the runway threshold. The crew did not initiate a go-around. Poor crew coordination was also noted.

Probable Cause

The official probable cause was the crew's wrong approach configuration, specifically a steep turn performed too late on final. Contributing factors included excessive touchdown speed, landing too far down the runway, failure to execute a go-around, and poor crew coordination.
