[1][6][7] The aircraft conducted an air-ambulance flight from San Jose, Costa Rica, to Fort Lauderdale in the United States.

[1] The aircraft departed Runway 09R around 7:50 p.m. From ATC audio recordings, it is understood that the controller instructed the crew to climb and maintain 7,000 feet.

At approximately 19:52, the controller again instructed the crew to turn left 240 degree heading, adding: "when you're able advise the airport in sight."

The aircraft descended through 900 feet and was able to turn towards the airport but could not arrest its descent and impacted the ocean approximately 1 mile offshore.

The United States Coast Guard found wreckage of the aircraft floating on the ocean surface the next day.

[1]: 7 The crash occurred in domestic waters, so the investigation was led by the National Transportation Safety Board (NTSB) with assistance from the Mexican Direction General of Civil Aeronautics (DGAC).

Aero JL records indicated that Moreno had been flying Learjet aircraft for the company since May 1, 2013, and at the time of the accident had a total of 1,243 flight hours.

Furthermore, the NTSB did not find any licenses, logbook, certificates, nor DGAC records to support Aero JL's claims of Moreno having 1,243 flight hours.

[1]: 2 The probable cause was determined to be deployment of the left engine thrust reverser by an unknown cause and failure of the flight crew to perform appropriate emergency procedures.
