JAKARTA: Indonesian divers hunted on Friday (Nov 2) for a second black box from an aircraft that crashed into the sea this week with the loss of all 189 people on board, as investigators tried to get data from a partly damaged recorder already found.
The Lion Air Boeing Co 737 MAX, which only went into service in August, crashed on Monday into the Java Sea.
Air traffic control lost contact with it 13 minutes after it took off from the capital, Jakarta, heading north to the tin-mining town of Pangkal Pinang.
Searchers have found one black box and just one passenger has been identified from partial human remains recovered from the shallow waters.
“We haven’t downloaded the data because there are some broken parts in the black box,” Haryo Satmiko, the deputy of the transport safety panel, said of the flight data recorder found on Thursday, adding that some of the damage was to a socket on the device.
Satimiko said investigators were awaiting advice from the US National Transportation Safety Board or Boeing.
The pilot of flight JT610 had asked for, and received, permission to turn back to Jakarta airport, but what went wrong remains a mystery.
Efforts are now focused on retrieving the second of the two black boxes, as the cockpit voice recorder and the flight data recorder are known, the head of Indonesia’s transport safety committee said.
“The team have been hearing the ‘ping’ sound from another black box for two days,” Soerjanto Tjahjono said.
The sea is only 30 m (98 ft) deep at the crash site but strong currents and nearby energy pipelines have hampered the search for the aircraft operated by the budget carrier.
While victims’ relatives are desperate to know what happened, the investigation of the first crash of a Boeing 737 MAX is also the focus of scrutiny by the global aviation industry.
