It was last week reported that the plane was climbing at a speed "beyond normal" before stalling.
Recovery efforts are still underway following the crash, which left all 162 on board dead.
AirAsia Flight QZ8501 experienced an explosion before hitting water, one of Indonesia's search and rescue officials has said.
The official said that the wreckage indicates that there was a change in pressure in the jet which caused the likely explosion.
