PANGKALAN BUN/JAKARTA: An Indonesian naval patrol vessel has found what could be the tail of a crashed AirAsia passenger jet, the section where the crucial black box voice and flight data recorders are located, officials said on Monday.

Ships and aircraft scouring the northern Java Sea for debris and bodies from the Airbus A320-200 have widened their search to allow for currents eight days after Flight QZ8501 plunged into the water en route from Indonesia’s second-biggest city of Surabaya to Singapore with 162 people on board.

“We found what has a high probability of being the tail of the plane,” Yayan Sofyan, captain of the patrol vessel, told reporters.

He was speaking after his ship returned to the port in Surabaya on Monday, and it was not immediately clear if he was referring to one of the five large objects pinpointed by search vessels over the weekend.

The recorders are housed in the tail section of the Airbus, making retrieval of that part of the aircraft crucial.

“I am not saying it’s the tail yet,” the head of Indonesia’s search and rescue agency, Fransiskus Bambang Soelistyo, told a news conference in Jakarta. “That is suspected. Now we are trying to confirm it.”
