Navy divers have recovered the cockpit voice recorder of a Lion Air jet that crashed into the Java Sea in October, Indonesian officials said Monday, in a possible boost to the accident investigation.
Ridwan Djamaluddin, a deputy maritime minister, told reporters that remains of some of the 189 people who died in the crash were also discovered at the seabed location.
A spokesman for the Indonesian navy’s western fleet, Lt. Col. Agung Nugroho, said divers using high-tech “ping locator” equipment started a new search effort on Friday and found the voice recorder beneath 8 meters (26 feet) of seabed mud. The plane crashed in waters 30 meters (98 feet) deep.
The device was transported to a port in Jakarta, where it will be handed over to the transportation safety committee, which is overseeing the accident investigation.
“This is good news, especially for us who lost our loved ones,” said Irianto, the father of Rio Nanda Pratama, a doctor who died in the crash.
“Even though we don’t yet know the contents of the CVR, this is some relief from our despair,” he said.
The 2-month-old Boeing 737 MAX 8 jet plunged into the Java Sea just minutes after taking off from Jakarta on Oct. 29, killing everyone on board.
The cockpit data recorder was recovered three days after the crash and showed that the jet’s airspeed indicator had malfunctioned on its last four flights.
If the voice recorder is undamaged, it could provide valuable additional information to investigators.
Rear Adm. Harjo Susmoro, head of the navy’s Center for Hydrography and Oceanography, said the voice recorder was found just 50 meters (164 feet) from where the data recorder was located.
He said the voice recorder’s signal, designed to last 90 days following a crash, would have stopped in about 15 days.
The Lion Air crash was the worst airline disaster in Indonesia since 1997, when 234 people died on a Garuda flight near Medan. In December 2014, an AirAsia flight from Surabaya to Singapore plunged into the sea, killing all 162 people on board.
Lion Air is one of Indonesia’s youngest airlines but has grown rapidly, flying to dozens of domestic and international destinations. It has been expanding aggressively in Southeast Asia, a fast-growing region of more than 600 million people.
