Indonesian authorities on Sunday extended by three days the search for victims and a black box from the wreckage of a Lion Air passenger jet that crashed near Jakarta last week, killing all 189 people on board.
“We decided to extend it three days”, beginning on Monday, search and rescue agency (Basarnas) chief Muhammad Syaugi told a news conference.
The decision was based on an evaluation and observations of the crash site, he told reporters, noting that many victims’ remains had not been recovered.
As of Sunday a total of 105 body bags, few containing intact remains, had been recovered and handed to police for forensic identification, yet only 14 victims had been identified.
“I’m sure the total will increase,” Syaugi said.
The agency is prioritizing recovering remains of victims and the cockpit voice recorder (CVR), the second of two black boxes from the Boeing Co. (BA.N) 737 MAX that crashed into the sea early on Monday, 13 minutes after it took off from Jakarta.
The head of Indonesia’s transportation safety committee (KNKT) said 69 hours of recorded data from 19 flights, including the one that crashed, had been downloaded successfully from a partly damaged flight data recorder recovered on Thursday.
“Now we are choosing which parameters we need. From here we will analyze what happened to that flight,” Nurcahyo Utomo told reporters. Analysis of the data and a recovered aircraft landing gear and engine will begin on Monday and information will be passed to police if needed, Utomo said.
“Of course, this won’t be completed in one or two days.”
Meanwhile, divers searching for the cockpit voice recorder have been homing in on ping signals.
“Yesterday there was a fairly strong signal. Today (a search) dive was conducted — there was a signal but it was weak, quite possibly because of the mud,” Utomo said.
He noted that the flight data recorder had been found buried in half a meter of mud.
The second black box is thought to be around 50 meters from the main search area, where the water is only 30 m (98 ft) deep, but ocean currents and mud on the sea bed that is over a meter deep have complicated search efforts.
The pilot of flight JT610 had asked for, and received, permission to turn back to Jakarta, but what went wrong remains a mystery.
While victims’ relatives are desperate to know what happened, the first crash of a Boeing 737 MAX is also the focus of scrutiny by the global aviation industry. Preliminary findings of the investigation are expected to be made public after 30 days.
Indonesia is one of the world’s fastest-growing aviation markets but its safety record has been patchy. Its transport safety panel investigated 137 serious aviation incidents from 2012 to 2017.
“There’s still a lot we need to improve,” Air Transportation Director General Pramintohadi Sukarno said at a press conference on Saturday, referring to safety rules.
