JAKARTA, Indonesia--Indonesia's search-and-rescue agency on Tuesday started a one-week break from searching for the remaining bodies of passengers aboard AirAsia Flight 8501, which crashed into the Java Sea on Dec. 28.

Tatang Zaenudin, deputy operations officer at the agency, said the search would resume next week, but with fewer people and equipment. They would continue the search for an additional week before halting operations for good, he said.

The crews were in need of rest after more than two months of operations, often hampered by bad weather, to bring up the wreckage of the aircraft and remains of the passengers and crew, Mr. Zaenudin said.

Mr. Zaenudin spoke in Surabaya, where the flight originated. The crashed plane was bound for Singapore with 162 passengers and crew on board. The remains of about 60 people remain unaccounted for.

The agency pulled up the final major part of the fuselage and wing of the Airbus A320 last Friday, but no bodies were inside and hopes dimmed that more remains would be found. Mr. Zaenudin said that some recent findings were only body parts.

Authorities haven't announced the cause of the crash, but the plane climbed steeply before going into a stall and descent. The agency handed over the mangled fuselage to the National Transportation Safety Committee at Jakarta's port for further investigation.
