Divers reported seeing the fuselage and engines of the crashed Lion Air jet on the seafloor and a ping locator has detected a signal that may be from the cockpit voice recorder, Indonesia's search and rescue chief said on Saturday.
Speaking on the sixth day of the search, Muhammad Syaugi said that two engines and more landing gear had been found.
"I haven't seen it myself but I got information from some divers that they have seen the fuselage," he said at a news conference at a Jakarta port where body bags, debris and passenger belongings are first taken.
The brand new Boeing 737 MAX 8 jet plunged into the Java Sea just minutes after takeoff from Jakarta early Monday, killing all 189 people on board.
The flight data recorder was recovered on Thursday and Syuagi said a "low ping signal" was detected by a sonar locator that could be the black box voice recorder.
Divers and a remotely operated vehicle have been searching the suspected location since Saturday morning.
