Investigators retrieve black boxes from Mexican plane after stormy crash

The Mexico City-bound Embraer 190 passenger jet smashed into scrubland near the runway shortly after the plane took off from an airport in northern Durango state on Tuesday. All 103 passengers and crew survived by evacuating the plane before it caught fire.

Nearly everyone on the flight suffered minor injuries, Mexican officials said.

Luis Gerardo Fonseca, director of Mexico’s civil aviation agency, told local news media on Wednesday that the recorders had been found. “We already have them,” he said in an interview with broadcaster Televisa.

Commercial aircraft carry a cockpit voice recorder and a flight data recorder, commonly known as “black boxes,” which can contain crucial details of the last minutes of a flight before an accident.

Video purportedly of the crash recorded from a plane window showed a dark sky and fog and the ground still visible moments before a thud and shrieking passengers were heard.

Reuters could not independently verify the video.

“The impact was very strong. We wanted to think it was a lightening strike,” said Chicago resident and passenger Lorenzo Nunez. “It was terrible, absolutely terrible.” Nunez said he had been visiting family in Durango.

A time-lapse video posted by Webcams of Mexico, filmed during the hour before the crash, showed dark clouds and fog or rain moving in.

Officials said it was too early to say what caused the crash of flight number 2431.

Aeromexico said in a Wednesday morning Twitter post that 64 people had been released from hospitals.

Two people were more seriously injured, including the pilot and a minor, the state health department said.

Fonseca told broadcaster ADN40 that his team began working at the crash site around 7 a.m. local time (1200 GMT), along with representatives of the US National Transportation Safety Board (NTSB) and US Federal Aviation Administration (FAA).

Representatives of Embraer SA and the maker of the plane’s engines, General Electric Co, were also assisting, Fonseca said.

It can take safety investigators months to piece together the complex chain of events leading to an accident.

Determining the cause of the Durango crash may be made easier by the location of the crash, which should allow easy access to evidence, such as the retrieved flight recorders, as well as interviews with the crew and other survivors.

Under international rules, Mexico will lead the investigation with support from Brazil, where the Embraer jet was designed and built, and from the United States, where General Electric Co (GE.N) made the CF34-10E engines.

Aeromexico leased the 10-year-old aircraft involved in Tuesday’s incident from Republic Airlines in the United States in 2014, according to data on Planespotters.net. A spokesman for Republic Airlines said on Wednesday that the company briefly leased the plane to Aeromexico, but the aircraft was sold to a third party in 2015. The airline did not give the name of the third party.
