Indonesian divers resumed a search on Tuesday for an airliner that crashed with 189 people on board, as “pinger locators” tried to zero in on its cockpit recorders and uncover why an almost-new plane went down in the sea minutes after take-off.
Indonesia, one of the world’s fastest-growing aviation markets, has a patchy safety record. With the now almost certain prospect of all on board having died, the crash is set to rank as its second-worst air disaster.
Ground staff lost contact with flight JT610 of budget airline Lion Air 13 minutes after the Boeing 737 MAX 8 aircraft took off early on Monday from the airport in Jakarta, the capital, on its way to the tin-mining town of Pangkal Pinang.
“Hopefully this morning we can find the wreckage or fuselage,” Soerjanto Tjahjono, the head of a national transport safety panel, told Reuters, adding that underwater “pinger locators”, including equipment from Singapore, were being deployed to help find the aircraft’s black boxes.
The priority is finding the cockpit voice recorder and flight data recorder to help determine the cause of the disaster, safety experts said.
Although divers stopped searching overnight, sonar vessels and an underwater drone kept up the hunt for the wreckage, where many victims were feared trapped, officials said.
Only debris and body parts have been found off the shore of Karawang, east of Jakarta.
A Reuters witness on a boat at the crash site, saw teams of divers in black rubber suits enter the slightly choppy water from six inflatable boats.
“The visibility is not good as it’s very overcast,” a special forces officer said, noting the dive team had started just after dawn and been down to a depth of 35 meters.
Underwater footage released by the national search and rescue agency showed relatively poor visibility. In all, 35 vessels are helping to search.
Yusuf Latif, the spokesman of the search and rescue agency, had said on Monday finding survivors “would be a miracle”, judging by the condition of the recovered debris and body parts.
Lion Air said human remains were collected in 24 body bags after sweeps of the site, in waters about 30 to 35 meters (98 to 115 ft) deep roughly 15 km (nine miles) off the coast.
Officers at Jakarta’s port picked through personal belongings retrieved from the sea, including wallets, backpacks and papers, in a bid to help identify their owners.
Dozens of relatives gathered at a police hospital where body bags were brought for forensic doctors to try to identify victims.
Police were taking saliva swabs from family members of the missing for DNA tests and also seeking details on body markings like tatoos or birthmarks on the passengers.
A tent has been set up next to the hospital building and a middle age woman and a teenager sat together, sobbing and comforting each other.
Boeing Providing Assistance
The pilot of flight JT610 had asked to return to base shortly after take-off about 6.20 a.m. Investigators are trying to determine why the pilot issued the request, which was granted.
No distress signal was received from the aircraft’s emergency transmitter.
The aircraft suffered a technical problem on a flight from the resort island of Bali to Jakarta on Sunday but it was “resolved according to procedure”, Edward Sirait, chief executive of Lion Air Group, told reporters.
Sirait declined to specify the nature of the issue but said none of the airline’s other aircraft of that model had the same problem. Lion had operated 11 Boeing 737 MAX 8s and it had no plan to ground the rest of them, he said.
On Monday, the U.S. National Transportation Safety Board (NTSB) and Boeing Co (BA.N) said they were providing assistance in the crash investigation.
