All 132 people aboard the China Eastern Airlines plane that crashed into a mountain in southern China are dead, a senior official in the Chinese aviation administration told Chinese state media Saturday.

China Daily reported the death toll, which comes after a days-long search-and-rescue mission that scoured the site of the country’s deadliest plane crash in nearly three decades. Search teams recovered a “black box” from the wreckage of the Boeing 737-800 jet earlier in the week but found no survivors.

China Eastern Airlines Flight 5735 had been carrying 123 passengers and nine crew members from Kunming toward Guangzhou when it nosedived into the mountains in Guangxi on Monday afternoon, according to video footage and witness accounts. The plane plunged more than 25,000 feet in less than three minutes and crashed into a mountain near Molang village in the city of Wuzhou, sparking a forest fire.

The cause of the crash has perplexed aviation authorities and experts. The weather was good, the pilots did not raise alarms and the plane did not appear to have broken apart in flight. China has one of the world’s strongest aviation safety records.

Outgoing Federal Aviation Administrator Steve Dickson called the type of Boeing plane that went down “one of the safest aircraft ever produced in commercial operation.”

Hundreds of firefighters and search-and-rescue teams were sent to the scene, local officials said. The U.S. National Transportation Safety Board has assembled a team of technical experts from the FAA, Boeing and engine manufacturer CFM International to join the Chinese investigation into the crash.

Search teams have retrieved one of the jet’s two black boxes, which contain recorded information from the flight that can help investigators determine the cause of a crash. But the black box had sustained serious damage, senior Chinese aviation administration official Mao Yanfeng said Wednesday.

Passengers on the plane included a young couple who had been taking their toddler daughter to get surgery in Guangzhou, executives from a Guangzhou mining company, a 22-year-old woman who had recently married and a 36-year-old woman returning to Guangzhou after going home for Lunar New Year, local media reported. More than 500 family members descended on the nearby city of Wuzhou after the crash to await word on the fates of relatives who had been onboard, China’s official Xinhua News Agency reported.

The crash is China’s deadliest since 1994, when a China Northwest Airlines flight crashed in Xian after an autopilot malfunction caused the plane to break up in midair, killing 160 people.
