According to survivor Jiang's memory, two cars picked up the nine survivors respectively-the first one picked up two flight attendants, while the other group was seven passengers. After seeing a doctor, it was a closed investigation.

Therefore, it can be judged that everyone in the cockpit died because of the air crash, including captain Lin (left seat), co-pilot Kong Dexin (right seat) and observer Xiao Rong.

Cause analysis:

(1) During the pentagonal approach, the attitude, track and glide slope of No.3456 aircraft remained normal before the altitude was determined, but the speed was too high (142.5 knots, the normal speed was 136 knots). The crew reported seeing the entrance lights and then reported seeing the runway. After determining the altitude, because the plane was flying in heavy rain, the crew decided to "turn on the light later" and used a rainproof agent.

(2) The average descent rate of the plane was 9.3 ft/s four seconds before landing, and the vertical overload reached 2.49G when landing, which caused the first jump and damaged the plane.

Due to operational errors, the plane jumped twice in a row. The second jump is 7 feet, the grounding vertical overload is 2.54G, and the third jump is 13 feet. Three consecutive jumps and overloading caused serious damage to the aircraft structure.

(4) Due to the damage of the control system, the plane left the ground at a speed of 183 knots and a small elevation angle of 2 degrees during the go-around (after the plane left the ground, the crew felt that the steering stick was "light" and the stick was "weightless"). After the plane was seriously damaged, the crew bypassed, laying a hidden danger for the second landing.

(5) After go-around, "main warning" and various warnings (hydraulic system, landing gear and flaps, etc. ) appears in the cockpit. After the damaged plane circled twice in the air, the crew decided to land in the opposite direction from north to south. Because the heavy rain has not stopped, the aircraft control system has failed (the change of steering rod obviously does not match the elevator deflection angle, the pull rod is large, and the elevator deflection angle is small). Although the crew pulled the stick to the end before landing, it failed to change the attitude of the plane flying at a large angle.
