Circumstances:
The airplane was departing Chongqing-Jiangbei Airport on a regular schedule service to Nyingchi, Tibet, carrying 113 passengers and a crew of nine. During the takeoff roll on runway 03, at a speed of 145 knots (just below V1 speed), the captain encountered an unexpected situation and decided to abandon the takeoff procedure. He initiated an emergency braking manoeuvre when the airplane started to deviate to the left. It veered off runway and went through a grassy area. While contacting the parallel concrete taxiway, the nose gear was sheared off. The airplane continued for 120 metres when it impacted a drainage ditch, causing both main landing gears and both engines to be sheared off as well. The airplane later came into a stop, bursting into flames. 36 occupants were injured while all others evacuated safely. The aircraft was destroyed.
Probable cause:
It was determined that, during the takeoff run, the captain was distracted by items falling, and momentarily lost the monitoring of the aircraft's flight sequence. During this short period of time, he unconsciously held the left rudder, which resulted in an unintended deviation of the aircraft to the left direction. After he noticed the deviation, the crew failed to execute the standard callouts, and the captain reduced the throttle in an attempt to abort the takeoff. Due to the combined effects of maximum braking force and inertia, the crew was unable to maintain a safe control, causing the airplane to veer off the runway to the left at a speed of approximately 127 knots. Poor decision makings on part of the crew was considered as the main cause of the accident.
