The flight data recorder was found to be a team-including divers and remotely operated submersibles-sweeping the seabed in search of the black box on Flight SJ 182 that crashed shortly after takeoff three days ago.
The flight data recorder processes flight information, including pressure, airspeed and altitude. The second black box has not been found, the cockpit voice recorder.
The commander-in-chief of the Indonesian National Armed Forces, Hadi Jajanto, said that the underwater acoustic beacons of the black box had been sent out. The beacons made a series of “pop” sounds to help searchers find them. But he is optimistic that they will find a second black box soon.
Soerjanto Tjahjono, head of the National Transportation Safety Board, said that it will take 2 to 5 days for the authorities to read the recovered black box data.
He said: “We hope that through this investigation, we can uncover the mystery of this accident.”
On Saturday afternoon, the Sriwijaya plane crashed into the waters northwest of the Indonesian capital Jakarta. The plane crashed between the Kuril Islands, a popular tourist destination among Indonesians, and then flew to Pontianak, a part of the Indonesian city on Borneo.
According to the global flight tracking service Flightradar24, four minutes after the flight, in heavy rain, the aircraft fell 10,000 feet in less than a minute and then disappeared from the radar.
Navy divers found the wreckage of the plane on Sunday after finding the signal from the plane’s fuselage.
A search team has filled dozens of body bags with human remains and recovered part of the plane and debris from the scene.
According to Flightradar24, the plane is a 26-year-old Boeing 737-500. Sriwijaya Airlines CEO Jefferson Irwin Jauwena said that the airliner was in good condition before takeoff.
Indonesia has a poor aviation safety record, and aircraft accidents are not uncommon.
This country of 270 million people relies heavily on air transportation, commuting between the entire archipelago, which stretches for more than 3,000 miles, about the same distance as London and New York.
According to data from the Australian consulting company CAPA-Center for Aviation, Indonesia’s domestic aviation industry has boomed in recent years, and passenger traffic has tripled between 2005 and 2017.
According to the company’s website, Sriwijaya Air is a low-cost airline and Indonesia’s third-largest airline, transporting more than 950,000 passengers from its Jakarta hub to 53 destinations in Indonesia and three regional countries every month.
