Investigation Summary
The flight was a routine domestic service from Beijing to Dalian. Approximately 43 minutes after takeoff, as the aircraft was descending toward its destination, the captain reported a fire in the cabin and later specified that the tail was on fire. Witnesses on the ground observed the aircraft circling low with visible flames in the cabin before it plunged into the sea at a steep angle. The wreckage was recovered from the shallow waters of Bohai Bay, where investigators found evidence of gasoline residue on seat cushions and carpet near the rear of the cabin. The investigation focused on Zhang Pilin, a passenger who had purchased an unusually high number of insurance policies totaling approximately 1.4 million yuan (170,000 USD). Investigators discovered that Zhang was in significant personal debt and had flown a round trip between Dalian and Beijing on the same day. Forensic evidence confirmed that Zhang was the source of the fire, having smuggled gasoline onto the plane in plastic bottles to commit arson for insurance fraud.
Final Conclusions
The Civil Aviation Administration of China (CAAC) concluded that the crash was caused by arson. The fire, intentionally set by passenger Zhang Pilin, led to a loss of control of the aircraft. The heat and smoke from the fire likely incapacitated the crew or damaged critical flight control systems located in the rear of the MD-82, making the aircraft unflyable. The motive was determined to be insurance fraud.
