Accident
On a cargo flight from Los Mochis Airport to Toluca on behalf of DHL, the aircraft was on descent when air traffic control advised the crew that visibility was reduced to 1,600 metres due to foggy conditions. While conducting a night approach to Toluca-Adolfo López Mateos Airport, the crew descended below the minimum descent altitude, likely in an attempt to establish visual contact with the ground. During the short final approach, the aircraft struck a two-metre-high concrete wall located 350 metres short of runway 15. The aircraft then crashed and burst into flames. All four occupants were killed.
Investigation
Investigation into the accident determined the probable cause and contributing factors.
Probable Cause
The official probable cause was controlled flight into terrain on short final after the crew decided to carry out an approach under VFR mode in IMC conditions until the aircraft impacted terrain. Contributing factors identified were poor visibility due to foggy conditions and the captain's overconfidence.
