JAKARTA - Indonesian authorities on Sunday located the black boxes of the Sriwijaya Air jet that crashed into the sea soon after taking off from the capital Jakarta, as human body parts and suspected pieces of the plane were retrieved.

The Boeing 737-500 with 62 people on board was en route to Pontianak in West Kalimantan before it disappeared on Saturday from radar screens four minutes after takeoff. 

The crash is the first major airline incident in Indonesia since the crash of a Lion Air Boeing 737 Max in 2018 that killed all 189 passengers and crew. That plane also crashed into the Java Sea soon after takeoff from Soekarno-Hatta airport.

Indonesia National Transport Safety Committee chief Soerjanto Tjahjono said the locations of Flight SJ 182’s two black boxes had been identified.

“Hopefully, we can retrieve them soon,” said military chief Hadi Tjahjanto, without giving an estimated timeframe.

Pieces of wreckage were brought to Jakarta port by rescuers. Authorities said they came from a depth of 23 meters near a group of islands off the Jakarta coast.

One twisted piece of metal was painted in Sriwijaya Air’s blue and red colors. Indonesian authorities said they had also retrieved body parts and clothing.

Police asked families to provide information such as dental records and DNA samples to help identify bodies.

The plane had 12 crew and 50 passengers on board, all Indonesians and including seven children and three babies.

President Joko Widodo, speaking at the palace in Bogor, expressed “deep condolences” over the disaster and urged the public to pray the missing people could be found.

“We feel powerless”

Tracking service Flightradar24 said the aircraft took off at 2:36 pm local time (0736 GMT) and climbed to reach 10,900 feet within four minutes. It then began a steep descent and stopped transmitting data 21 seconds later.

We feel powerless, we can only wait and hope to get any information soon.

There were no immediate clues on what caused the jet’s sudden descent. Most air accidents are caused by a cocktail of factors that can take months to establish, safety experts say.

A transport ministry spokeswoman said air traffic control had asked the pilot why the plane was heading northwest instead of on its expected flight path seconds before it disappeared.

The pilots had decades of experience between them with the flight captain reported to be a former air force pilot and his co-pilot at Sriwijaya Air since 2013, according to his Linkedin profile.

The Sriwijaya Air plane was a nearly 27-year-old Boeing 737-500, much older than Boeing’s problem-plagued 737 MAX model. Older 737 models are widely flown and do not have the stall-prevention system implicated in the MAX safety crisis.

“We are in contact with our airline customer and stand ready to support them during this difficult time,” Boeing said in a statement. “Our thoughts are with the crew, passengers, and their families.”

Distraught relatives waited at Pontianak about 740 km from Jakarta for news of their loved ones. At Jakarta’s main airport a crisis centre was set up for relatives.

“We feel powerless, we can only wait and hope to get any information soon,” Irfansyah Riyanto, who had five relatives on the flight, told reporters.

Founded in 2003, Jakarta-based Sriwijaya Air group flies largely within Indonesia. The budget airline has had a solid safety record, with no onboard casualties in four incidents recorded on the Aviation Safety Network database.
