The plane’s flight-data recorder and cockpit voice recorder were recovered from the crash and sent to the US National Transportation Safety Board (NTSB) in Washington DC for analysis, Chinese state media earlier.Īmerican officials involved in the investigation are focusing on the actions of a pilot, the Journal reported, adding that it is also possible that someone else on the plane could have broken into the cockpit and deliberately caused the crash. “The plane did what it was told to do by someone in the cockpit,” the Journal quoted a person who is familiar with American officials’ preliminary assessment as saying.

Information extracted from the plane’s damaged flight-data recorder shows human input orders to the controls sent the plane into its deadly dive, according to the Journal, citing people familiar with the probe. It was China’s deadliest air disaster in decades.

The Boeing 737-800 was flying from Kunming to Guangzhou when it nosedived from 29,000 feet mid air into the mountains, killing all 132 passengers and crew on board. If accidents do happen due to negligence, not only will the personnel in charge be punished, the relevant top officials will also be investigated, state media said.Black box data recovered from a China Eastern flight that crashed in March suggests someone in the cockpit intentionally downed the plane, the Wall Street Journal reported, citing a preliminary assessment from United States officials. Information about the crash must be released in an open, timely and transparent manner, state media said in a report on the meeting of the seven-person Standing Committee of the Communist Party's politburo, China's top leadership.Ī nationwide safety inspection should also be launched to prevent as much as possible the occurrence of safety accidents, state media said. On Thursday, Chinese state media said the cause of the crash must be determined as soon as possible, following a meeting of China's highest decision-making body helmed by President Xi Jinping.

Under an international agreement, the NTSB has the right to participate since the plane was designed and built in the United States. CAAC News, a publication under the Chinese aviation regulator, said on Saturday that the NTSB group of seven investigators and technical advisers had arrived in China.
