Descripción:Flight MH684 took off from Singapore at 18:53 for a flight to Kuala Lumpur. Approaching Kuala Lumpur, the aircraft was cleared for an ILS runway 15 approach. At 19:20 RVR was 450m in heavy rain showers. Though below company the minimum of 800m, the captain elected to continue the approach, hoping to see the runway. The captain took over control from the first officer, shortly before entering an area of heavy rain showers. Immediately after selecting the windscreen wipers 'on', the radio altimeter sounded. Less then 30 seconds later, the Airbus contacted some trees 2km short of the runway and the right main gear struck the ground and continued for 436m. The aircraft then lifted off for 36m before striking a stream embankment and it slid for 109m before coming to rest, 1200m short of the runway. The landing gear and both engines were torn off and a fire erupted, destroying the cabin and cockpit roof.
PROBABLE CAUSE: "The flight crew's failure to follow procedural requirements coupled with insufficient monitoring during the approach in instrument meteorological conditions (IMC) and that the approach was continued to below the minimum descent altitude (MDA) without having positive visual references."
