Recovery crews have found the second black box — the flight data recorder — from the wreckage of a China Eastern Airlines Boeing 737-800 jet that crashed into a mountainside in southern China last week.
Flight MU5735 crashed on March 21, killing all 132 people onboard, in China's deadliest aviation disaster in 28 years.
Heading to coastal Guangzhou from the south-western city of Kunming, the plane dived from cruising altitude around the time it should have started its landing descent.
The dead included nine crew members.
The black box, which could shed light on the cause of the crash, has been sent to Beijing for examination and analysis, state media reported.
The other black box — the cockpit voice recorder — was delivered to experts in the Chinese capital after being found on Wednesday.
Crash cause remains unknown
It was too soon to determine the cause of the crash, and crashes are usually the result of a combination of factors, experts said.
The second black box was dug out of a slope at the crash site about 9:20am local time in muddy conditions after rain in recent days.
The device, part of which was badly damaged, was recovered 1.5 metres underground and 40 metres from the point of impact, said Zhu Tao, head of aviation safety at the Civil Aviation Administration of China.
"Civil aviation investigators at the site confirmed that the storage unit of the flight data recorder has been found," Mr Zhu told a news conference in Guangxi.
The crash was the deadliest since a China Northwest Airlines flight from Xian to Guangzhou crashed, killing all 160 people on board.
Last Monday's flight briefly appeared to pull out of its nosedive before resuming its plunge to earth, according to flight-tracking website FlightRadar24.
Its data showed the aircraft was plummeting 31,000 feet per minute.
The pilots did not respond to repeated calls from air traffic controllers and nearby planes during the rapid descent, authorities said.
The disaster has shocked China, sending social media into overdrive as netizens parsed what little was known for clues.
Conspiracy theories blocked by watchdog
China's cyberspace watchdog ordered internet platforms and websites to clamp down on rumours, conspiracy theories and any online mockery of the disaster.
Since the crash, authorities have banned users and closed accounts to deal with more than 167,000 rumours, ranging from the deaths of seven directors of a company to divine prophesies of a plane crash by the end of March.
China is leading the crash investigation. The US has been invited to take part, as the Boeing 737-800 was designed and manufactured there.
The US National Transportation Safety Board said it was working with US and Chinese authorities to resolve visa and COVID-19 quarantine issues before participating.
