Microburst factor in Aeroméxico Embraer ERJ-190 takeoff accident at Durango, Mexico
Investigators issued a preliminary report on the Aeroméxico Embraer ERJ-190 takeoff accident at Durango, Mexico, stating a microburst (windshear) event was a factor.

On July 31, 2018, Aeroméxico Flight AM2431 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.
The investigators issued a preliminary report on September 5, stating the flight encountered a microburst (windshear) phenomenon with descending and rapidly changing wind. In more detail the flight data recorder shows that the aircraft commenced the takeoff roll on runway 03 at 15:22 hours local time. 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.

The investigation is ongoing. The final results will be published in November 2018.



Mexican airline fires 3 pilots involved in Durango crash

Mexican airline Aeromexico says it has fired three pilots involved in an accident that saw a jet crash belly-down into a field in July.

Investigators said earlier that a trainee pilot was improperly seated in the co-pilot's seat when the plane took off.

They said the plane's commanding officer took over controls from the trainee just before the crash.

The airline said in a letter to employees published Thursday that the pilots' actions were "in direct violation of our company's policies, manuals and procedures."

Investigators blamed a sudden downdraft known as a microburst for bringing the jet, and said there was no evidence of pilot error.

All 103 people aboard survived, some with injuries, in the July 31 crash.
