Aeroméxico Flight 2431 operated by an Aeroméxico Connect Embraer ERJ-190 impacted airport terrain shortly after commencing takeoff from runway 03 at Guadalupe Victoria International Airport (MMDO), Durango, and a post-impact fire ensued. All 105 occupants survived but 49 suffered injuries that required hospitalization.
The aircraft arrived at Durango from Mexico City as flight 2430 at 14:11 hours local time, 23 minutes ahead of schedule. As the ERJ-190 was prepared for the return flight there was a broken layer of cumulonimbus clouds at 2500 feet. Airport weather information shows that a thunderstorm had developed by 15:18 hours local time and the temperature had dropped from 28°C to 20°C over the previous hour.
On board flight AM2431 were two flight crew members, an observer, three cabin crew members and 99 passengers. The aircraft commenced the takeoff roll on runway 03 at 15:22 hours local time (planned departure time was 15:09 hours).
During the takeoff roll there were notable variations in airspeed and wind direction. At 15:22:42 hours, the aircraft was accelerating through an airspeed of 146 knots. Wind at that time was 47 degrees (from the right-hand side) at 33 knots. Eight seconds later the aircraft had rotated and was climbing through 8 feet radio altitude at an airspeed of 145 knots. By that time the wind had shifted to a crosswind: 103 degrees at 11 knots. The aircraft reached a highest altitude of about 30 feet. At 15:22:56 hours, the aircraft had descended to 19 feet and was caught in a 22-knot tailwind of 30 degrees.
The aircraft then hit the ground to the left of the runway, left wing first. Both engines broke away during the subsequent ground slide. The aircraft came to rest about 380 meters past the runway threshold and 320 meters past the paved end of the runway, slightly to the left of the extended centreline. The length of runway 03 is 2900 m (9514 ft).

On September 5, 2018, the investigation committee reported issued a preliminary report, stating the engines of the aircraft were functioning normally. It appeared the flight encountered a microburst (windshear) phenomenon with descending and rapidly changing wind.
