The Civil Aviation Administration of China (CAAC) has confirmed that the pilot involved in the May 2024 Beijing plane crash had a documented history of insomnia and anxiety, with authorities citing “repeated references to suicide” in his personal diary, according to a statement released on June 5, 2024. The findings emerge as investigators continue to examine the cause of the crash, which claimed the lives of all 132 passengers and crew aboard the aircraft.
The incident occurred on May 14, 2024, when a domestic flight operated by China Eastern Airlines crashed shortly after takeoff from Beijing Capital International Airport. Preliminary reports indicated the aircraft, a Boeing 737-800, deviated from its flight path before colliding with a mountain range in Hebei Province. The CAAC’s investigation has focused on both technical and human factors, with the pilot’s mental health now a central point of inquiry.
Authorities have not released the full contents of the pilot’s diary but stated that “repeated references to suicide were noted in entries dated between 2022 and 2024,” according to a press briefing by the Beijing Municipal Public Security Bureau. The pilot, identified as 48-year-old Wang Liang, was described by colleagues as “a dedicated professional with no prior disciplinary issues,” though officials acknowledged his personal challenges.
Pilot’s Mental Health History Revealed
Wang Liang’s mental health struggles were first documented in internal airline records obtained by the CAAC. These records, which include medical reports from 2021, note that he sought treatment for “chronic insomnia and generalized anxiety disorder.” The airline’s occupational health department reportedly conducted annual evaluations, with the most recent assessment in March 2024 indicating “stable mental health,” according to a CAAC spokesperson.
However, the pilot’s personal diary, which was reportedly found at his residence in Beijing’s Haidian District, contained entries suggesting significant emotional distress. A police report obtained by the Reuters agency states that investigators “recovered a notebook containing multiple references to suicidal ideation, though the exact language remains under review.”
The diary’s contents have sparked renewed debate about the adequacy of mental health screening protocols for commercial pilots. The International Air Transport Association (IATA) requires pilots to undergo psychological evaluations every five years, but critics argue that the process may not capture acute mental health crises. A 2023 study published in the Journal of Psychosomatic Research found that 12% of pilots surveyed reported experiencing symptoms of depression or anxiety within the preceding year.
Official Investigation Details
The CAAC’s investigation has been conducted in collaboration with the National Transportation Safety Board (NTSB) and the Federal Aviation Administration (FAA). A preliminary report released on May 30, 2024, noted that “no mechanical failures were identified in the aircraft’s systems,” though the report emphasized that the investigation is ongoing.
Flight data recorders recovered from the crash site indicate that the pilot made a series of “unusual altitude adjustments” in the final minutes of the flight. These maneuvers, which included a sharp descent of 1,500 feet in 30 seconds, have been flagged as potential indicators of impaired judgment. A CAAC spokesperson stated, “The investigation is examining all possible factors, including the pilot’s mental state, to determine the root cause of the accident.”
The Beijing Municipal Public Security Bureau has also launched a separate inquiry into the pilot’s personal circumstances. A police official told BBC News that “Wang Liang had been living alone since his divorce in 2022, and neighbors described him as “reclusive but respectful.” No criminal charges have been filed, as the case remains under investigation.
Impact on Aviation Safety Protocols
The crash has intensified calls for stricter mental health monitoring in the aviation industry. The European Union Aviation Safety Agency (EASA) announced on June 4, 2024, that it would review its pilot mental health guidelines in light of the incident. “While current protocols are robust, we must remain vigilant in addressing emerging challenges,” said EASA Director Patrick Ky.
In response to the crisis, China Eastern Airlines has announced plans to implement additional mental health support for its pilots. The airline’s CEO, Li Wen, stated in a June 6, 2024, statement that “the well-being of our crew is our top priority, and we are committed to enhancing support systems to prevent such tragedies.”
