The co-pilot of AirAsia Flight QZ8501 was flying the passenger jet when it crashed last month, officials have said.
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.
The fuselage of the crashed AirAsia passenger jet which came down off the coast of Indonesia has been located by the Singapore military, the country's defence minister has said.
In a message posted to Facebook, Ng Eng Hen said he had been informed of the find by his navy chief, and posted underwater pictures.
A spokesman for the Indonesian navy said they had been able to capture images of wreckage which was 20 metres long, seven metres wide and three metres high - but said they had not yet been able to confirm whether it was from the jet.
Indonesia AirAsia's Flight QZ8501 went missing on December 28 after requesting a diversion due to bad weather.
