What happened
During the final approach phase at Sydney, the aircraft descended lower than intended and collided with an earth mound located short of the runway threshold. Upon impact, the undercarriage punctured a fuel tank, which immediately triggered a fire. Despite the collision and subsequent ignition, the aircraft completed its landing sequence safely. It came to rest on the ground fully engulfed in flames, resulting in damage that rendered it beyond repair. Remarkably, all 17 occupants emerged from the incident unhurt.
Findings
The primary contributing factor identified was the aircraft being too low during the final approach segment. This deviation led directly to the collision with the terrain feature prior to reaching the runway threshold.
