Fifteen of the U.S. passengers that survived the crash of Aeromexico Flight 2431 on July 31, 2018 filed a lawsuit against the airline, announced the law firm Corboy & Demetrio.

The Aeromexico Embraer 190, registration XA-GAL, crashed shortly after takeoff in Durango state, in northern Mexico. 85 people were injured, no fatalities were reported. The plane was operating connecting flight AM2431 between Durango International Airport (DGO) and Mexico City International Airport (MEX) with 103 passengers and crew members on board.

Describing the weather conditions at the time of a crash as “a heavy storm including severe wind, rain, and hail”, the law firm questions the decision of the airline to operate under such condition.

“All of the people on this flight have the right to know exactly what caused the plane to crash.  A plane just doesn’t drop from the sky because it’s raining hard,” said Corboy & Demetrio in its statement. “Weather, to some extent, is always a factor in flight operations. However, safe flight operations depend on how the airline and its pilots monitor, respond to and correct for severe weather conditions, both in the preflight and inter-flight decision making process, in order to avoid a mishap.”

The investigation to identify the reasons behind the crash is still ongoing. The flight crew was interrogated, with the exception of the captain still recovering in a hospital after being treated for a spinal injury.

The law firm initially filed eleven lawsuits on August 6, 2018, followed by four more on August 10, 2018.
