Indonesian search team may have found the flight recorders of missing AirAsia flight QZ8501, search and recovery operation head said.
Bambang Sulistoyo added that divers would try to retrieve them on Monday, reported the BBC.
They are buried on the seabed underneath the flight's wreckage, officials said.
An official had earlier said that a large object resembling the plane's body had been found in a sonar scan of the search area in the Java Sea. However, Supriyadi, operations co-ordinator for Indonesia's search-and-rescue agency, later said that the claim had not been confirmed.
Flight QZ8501 went down into the Java Sea on December 28 with 162 people on board while flying from Surabaya in Indonesia to Singapore.
Rescue teams have been pulling out bodies and debris from the sea. Nearly 48 bodies have been found so far.
