The second black box, or flight data recorder, of the crashed China Eastern MU5737 Boeing 737-800, was found  on Sunday morning, according to Xinhua News Agency, and the two black boxes are expected to provide some clues that might explain the tragic crash.

CCTV reported it was found beneath a 1.5-meter layer of soil at the crash site.

The first black box was found from the crash site in South China's Guangxi Zhuang Autonomous Region on Wednesday night, days after the crash happened.

But Chinese officials said  the possibility of damage to the storage unit of the first black box cannot be ruled out.

The first black box was delivered to a decoding lab in Beijing. The analysis of its data is underway. 

According to the configuration of the Boeing B737-800 aircraft, both recorders are installed in the rear of the aircraft. The cockpit voice recorder is located in the rear cargo compartment and the flight data recorder is located above the ceiling in the rear of the cabin.

The two black boxes are significant for finding the cause of the air crash, and the data of the two recorders can confirm and support each other, Huang Jun, a professor of School of Aeronautic Science and Engineering with Beihang University, told the Global Times.

Officials announced on Saturday night that that all 132 onboard flight MU5735, 123 passengers and nine crew members, have been confirmed dead, Xinhua News Agency reported.
