A Tibet Airlines Airbus A319-100, registration B-6425 performing flight
TV-9833 from Chongqing to Nyingchi (China) with 113 passengers and 9 crew, was accelerating for takeoff from Chongqing's runway 03 at about 08:04L (00:04Z) when the aircraft went left off the runway, crossed the paralell taxiway, crossed another taxiway connecting runway and the two parallel taxiways, left both engines (CFM56) and the landing gear behind and came to a stop off the runway on soft ground between the two parallel taxiways. A fire broke out at the left forward side of the aircraft, the aircraft was evacuated via slides. 36 people received minor injuries in the accident, the aircraft sustained damage beyond repair.
Tibet Airlines reported 113 passengers and 9 crew were on board, the aircraft was taking off when the crew noticed some anomaly. The aircraft veered off the runway, some occupants received minor injuries.
China's Civil Aviation Authority confirmed 36 people received minor injuries in the accident.
On May 19th 2022 the CAAC (Civil Aviation Authority China) reported the gears collapsed, the engines separated, part of the fuselage suffered from fire after rejected takeoff. The occurrence was rated an accident and is being investigated.
On Jun 5th 2024 China's Civil Aviation Authority released their final report in Chinese only dated May 4th 2023 (Editorial note: to serve the purpose of global prevention of the repeat of causes leading to an occurrence an additional timely release of all occurrence reports in the only world spanning aviation language English would be necessary, a Chinese only release does not achieve this purpose as set by ICAO annex 13 and just forces many aviators to waste much more time and effort each in trying to understand the circumstances leading to the occurrence. Aviators operating internationally are required to read/speak English besides their local language, investigators need to be able to read/write/speak English to communicate with their counterparts all around the globe).
The report concludes the probable causes of the accident were:
During the takeoff roll at a speed close to V1 (145 KIAS) the first officer pressed the left rudder to maintain runway direction. The captain was disturbed by falling objects and lost situational awareness, inadvertently the captain also applied left rudder which combined with the first officer's input caused the left deviation. Upon detecting the deviation the crew did not perform the standard call outs, the captain retarted the throttle levers. Under the influence of maximum braking and inertia the crew failed to make effective corrections and the aircraft veered off the runway at high speed (about 127 KIAS).
After veering off the runway the nose gear collapsed after collision with a cover plate and shoulder of a taxiway, the aircraft continued forward and struck an open ditch about 120 meters west of the runway 03 center line. That impact caused the engine, main landing gear and other components to detach and the aircraft's belly contacted ground leading to a fire.
Based on the injuries and damage this constitutes an accident caused by human error.
