JAKARTA, Indonesia — An Indonesian search team on Saturday pulled the tail section of the AirAsia plane that crashed last month from the Java Sea, but the aircraft’s data recorders were not inside, officials said.

Ships taking part in the search for the plane, an Airbus A320-200 that crashed on Dec. 28 with 162 people aboard, began to detect signals from the plane’s flight data and cockpit voice and recorders on Thursday. But officials have since said they believe that the crash’s impact dislodged the recorders from their original housing in the tail section.

“The search for black boxes is continuing,” Indonesia’s transportation minister, Ignasius Jonan, said at a news conference on Saturday.
