"The lifting up process is underway now, using both  floating balloons and a crane. Fifteen divers have been sent to handle the  process from below the surface," an agency official said.

The AirAsia flight QZ8501 with 162 people - 155  passengers and seven crew - went missing soon after taking off from  Indonesian city of Surabaya for Singapore on December 28.

The official said that floating balloons are used  to raise the tail from the seabed. The crane would tow the tail to a navy ship. Efforts to hoist the tail failed Friday  due to the bad weather in the crash site.

Meanwhile, the Indonesia authorities have also sent  divers to locate the ping signals from the crashed flight which were detected on Friday morning and believed to be from the black boxes.

So far, 46 bodies have been recovered from the sea.
