HAVANA (AP) — A Cuban airliner with 104 passengers on board plummeted into a yuca field just after takeoff from Havana’s international airport on Friday. There was no immediate word on casualties.

Officials said the plane was headed to the eastern city of Holguin when it crashed a short distance from the end of the runway on the southern outskirts of Havana.

The plane lay in a field of yuca-root plants and appeared heavily damaged and burnt. Firefighters were trying to extinguish its smoldering remains. Government officials including President Miguel Diaz-Canel rushed to the site, along with a large number of emergency medical workers. Residents of the rural area said they had seen some survivors being taken away in ambulances.

Relatives of passengers rushed to the scene, among them a man who said that his wife and niece had been on board. He declined to provide his full name before he was taken to an airline terminal where relatives were being asked to gather.

A military officer who declined to provide his name to reporters said that there appeared to have been only three survivors in critical condition, but other officials declined to confirm that figure.

The plane was rented by Cubana, which has taken many of its aging planes out of service in recent months due to mechanical problems. Cuba’s First Vice-President, Salvador Valdes Mesa, met Thursday with Cubana officials to discuss improvements in its heavily criticized service. The airline is notorious among Cubans for its frequent delays and cancellations, which Cubana blames on a lack of parts and airplanes due to the U.S. trade embargo on the island.

The crash Friday was Cuba’s third major fatal accident since 2010.

Last year, a Cuban military plane crashes into a hillside in the western province of Artemisa, killing eight troops on board. In November 2010, an AeroCaribbean flight from Santiago to Havana went down in bad weather as it flew over central Cuba, killing all 68 people, including 28 foreigners, in what was Cuba’s worst air disaster in more than two decades.

The last Cubana accident appears to have been on Sept. 4, 1989, when a chartered Cubana plane flying from Havana to Milan, Italy, went down shortly after takeoff, killing all 126 people on board, as well as at least two dozen on the ground.

Cubana’s director general, Capt. Hermes Hernandez Dumas, told state media last month that Cubana’s domestic flights had carried 11,700 more passengers than planned between January and April 2018. It said that 64 percent of flights had taken off on time, up from 59 percent the previous year.

“Among the difficulties created by the U.S. trade embargo is our inability to acquire latest-generation aircraft with technology capable of guaranteeing the stability of aerial operations,” Hernandez said. “Another factor is obtaining part for Cubana’s aircraft.”
