Sichuan Airlines Flight 8633

Sichuan Airlines Flight 8633 was a flight from Chongqing Jiangbei International Airport to Lhasa Gonggar Airport on 14 May 2018, which was forced to make an emergency landing at Chengdu Shuangliu International Airport after the cockpit windshield failed. The aircraft involved was an Airbus A319. The incident was adapted into the 2019 film The Captain and was also featured in the documentary series Mayday.

Incident

On 14 May 2018, Flight 8633 took off from Chongqing Jiangbei International Airport at 6:25 CST (22:25 UTC). Approximately 40 minutes after departure while over Xiaojin County, Sichuan, at the altitude of 9 km, the right front segment of the windshield separated from the aircraft followed by an uncontrolled decompression. As a result of the sudden decompression, the autopilot panel was damaged, and the loud external noise made spoken communications extremely difficult. The co-pilot, however, was able to use the transponder to squawk 7700, alerting Chengdu Shuangliu International Airport control about their situation. Because the flight was within a mountainous region, the pilots were unable to descend to the required 8,000 ft (2,400 m) to compensate for the loss of cabin pressure.

About 35 minutes later, the jetliner made an emergency landing at 7:42 CST (23:42 UTC) at Chengdu Shuangliu International Airport. The aircraft was overweight on landing. As a result, the plane took a longer distance to come to a stop.

Despite wearing a seatbelt, first officer Xu was partially blown out of the aircraft. He suffered facial abrasions, a minor right eye injury and a sprained wrist. One of the flight attendants on the aircraft, Zhou Yanwen (周彦雯), also suffered a wrist injury and received treatment. Owing to the insulation design of the Airbus A319, the temperature did not drop immediately for the passengers, despite the cockpit's exposure to the outside environment, saving them from frostbite. Even though the plane was unable to descend at the time of the incident due to the surrounding terrain, the flight crew remained conscious and did not experience hypoxia or frostbite. No other crew member or passenger was injured.
