Authorities have pinpointed the location of two black boxes from a crashed Indonesian jet, they said Sunday, referring to cockpit voice and flight data recorders that could help explain why the aircraft went down with 62 people aboard.
The announcement came as divers pulled body parts, wreckage and clothing from waters off Indonesia’s capital Jakarta.
“We have located the position of the black boxes, both of them,” said Soerjanto Tjahjanto, head of Indonesia’s transport safety agency.
“Divers will start looking for them now and hopefully it won’t be long before we get them.”
The Sriwijaya Air Boeing 737-500 went into a steep dive about four minutes after it left Soekarno-Hatta international airport in Jakarta on Saturday afternoon.
Indonesia’s President Joko Widodo expressed his “deep condolences”, and called on citizens to “pray together so that victims can be found”.
But the frantic search involving helicopters and a flotilla of warships appeared to offer no hope of finding any survivors.
The search and rescue agency said it had so far collected five body bags with human remains as well as debris from the crash site in the Java Sea.
A piece of child’s clothing, a broken tyre and wheel, life jackets and wreckage from the plane’s body were found, according to authorities and AFP reporters on the scene.
Among the passengers was Beben Sofian, 59, and her husband Dan Razanah, 58.
“They took a selfie and sent it to their kids before taking off,” the couple’s nephew Hendra told AFP.
All 62 people on board, passengers and crew, were Indonesian, authorities said. The count included 10 children.
Data from FlightRadar24 indicated that the airliner reached an altitude of nearly 11,000 feet (3,350m) before dropping suddenly to 250 feet. It then lost contact with air traffic control.
The transport minister said Saturday that the jet appeared to deviate from its intended course just before it disappeared from radar.
Poor weather, pilot error or a technical problem with the plane were potential factors, said Jakarta-based aviation analyst Gerry Soejatman.
“But it’s way too early to conclude anything,” he added.
“After the black box is found we can start putting the puzzle together.”
Sriwijaya Air, which operates flights to destinations in Indonesia and Southeast Asia, has said only that it was investigating the loss of contact.
It did not immediately comment when contacted by AFP again on Sunday.
Reputation for poor safety
In October 2018, 189 people were killed when a Lion Air Boeing 737 MAX jet crashed near Jakarta.
That crash – and another in Ethiopia – saw Boeing hit with US$2.5 billion in fines over claims it defrauded regulators overseeing the 737 MAX model, which was grounded worldwide following the two deadly crashes.
The 26-year-old 737 that went down Saturday was not a MAX variant.
“Our thoughts are with the crew, passengers, and their families,” Boeing said in a statement, adding that it was in contact with the airline.
Indonesia’s aviation sector has long had a reputation for poor safety, and its airlines were once banned from entering US and European airspace.
In 2014, an AirAsia plane headed from Surabaya to Singapore crashed with the loss of 162 lives.
Domestic investigators’ final report on that crash said major factors included a chronically faulty component in a rudder control system, poor maintenance, and the pilots’ inadequate response.
A year later, in 2015, more than 140 people, including scores on the ground, were killed when a military plane crashed shortly after take-off in Medan on Sumatra island.
