HAVANA — An investigation into the crash of a Boeing 737 jet near Havana a year ago, in which 112 people died, suggests that the likely cause was errors by crew members, who died in the crash, Cuban officials said on Thursday.

The 39-year-old plane, which was leased by a little-known Mexican company, Damojh, to Cuba’s flagship carrier, Cubana, dived into fields south of Havana shortly after taking off on May 18, 2018, for the eastern Cuban city of Holguin. The plane burst into flames, and all but one of the 113 people on board died.

“The most probable cause of the accident were the actions of the crew and their errors in the calculations of weight and balance that led to loss of control of the plane and its fall during the takeoff phase,” the Cuban Institute of Civil Aeronautics said in a statement.

Crew members, who were Mexican, were included in Damojh’s lease agreement with Cubana. Most passengers on the flight were Cuban.
