About China Eastern Airlines flight 5210:

At 7: 45 am on November 21st, 2004, a Bombardier CRJ-200 regional aircraft belonging to China Eastern Airlines Yunnan Branch (civil aviation registration number B-3072, manufactured on November 19th, 2002, fuselage serial number 7697) was still a new aircraft, with a total flight time of 4,611 hours and 3,560 take-offs and landings at the time of the incident. Although the B-3072 originally belonging to Yunnan Airlines was owned by Eastern Airlines at that time, the assets reorganization of Eastern Airlines and Yunnan Airlines has not been completed yet, so the B-3072 still retained the painting of "China Yunnan Airlines" at that time, and was preparing for takeoff. When the plane is ready to fly, it will fly from Baotou Erli Half Airport to Shanghai Hongqiao International Airport for MU5210. There were 3 crew members, 2 flight attendants, 1 security officer and 47 passengers (38 male passengers and 9 female passengers, including 1 Indonesian passenger) on board. The actual total weight of the aircraft at that time was 23,175 kg, which was within the maximum takeoff weight of 24,040 kg, and there was no overload.
Wang Pinshi, the captain of flight MU5210, was 33 years old. He graduated from the Driving Department of Civil Aviation Flight Academy of China in May 1994. His driving licenses were Boeing 737 and Bombardier CRJ-200, with a total flight duration of 6,851 hours and 34 minutes. In December 2001, he completed the modification of CRJ-200 and flew on CRJ-200 for 1,980 hours and 36 minutes. He was sitting in the left seat driving position that day. The second captain, Yang Guangguang, was 37 years old. He graduated from the Third Flight Academy of the Air Force in July 1989. His driving licenses were Boeing 737 and Bombardier CRJ-200, with a total flight duration of 6,001 hours and 39 minutes. In June 2004, he completed the modification of CRJ-200 and flew on CRJ-200 for 169 hours and 44 minutes. He sat in the middle observer seat that day. Co-pilot Yi Qinwei was 26 years old. He graduated from the Driving Department of Civil Aviation Flight Academy of China in September 2001. His driving license was Bombardier CRJ-200, with a total flight duration of 1,229 hours and 51 minutes. In January 2003, he completed the modification of CRJ-200 and flew on CRJ-200 for 979 hours and 57 minutes. He was sitting in the right passenger seat that day.
Flight attendant Huang Chongyan was 27 years old and joined the cabin department of China Eastern Airlines Yunnan Company in April 1997, with a total flight duration of 9,138 hours and 54 minutes. Shi Meilian, a flight attendant, was 22 years old and joined the cabin department of China Eastern Airlines Yunnan Company in July 2002, with a total flight duration of 2,636 hours and 57 minutes. Jiang Chaohong, a security officer, was 35 years old. He joined the cabin department of China Eastern Airlines Yunnan Company in March 1999, with a total flying time of 9,670 hours and 25 minutes. The licenses of all members of the crew and crew are within the prescribed validity period, and they all rest in accordance with the regulations 24 hours before the flight mission, without taking any illegal drugs and alcoholic beverages.
At 8: 10, the cabin door was closed, and at 8: 11, the crew applied to Baotou Airport Tower Control for clearance. At 8: 14, Baotou Tower Control issued a release permit to the flight crew of MU5210: "5210 was released to Shanghai Hongqiao, the route was as planned, the ground was calm, the sea pressure was revised to 1027, the visibility was 4 kilometers, and the runway 13 was used for takeoff, and the transponder 0035 was used." MU5210 unit: "5210 understand, release Shanghai Hongqiao, the route is as planned, the ground is calm, the temperature is MINUS 7?, the sea pressure is revised to 1027, the visibility is 4 kilometers, and the take-off uses runway 13 and transponder 0035." At 8: 15, the crew of flight MU5210 started two GE CF34-3B1 turbofan engines of aircraft B-3072 with the permission of the tower. Three minutes later, the crew requested the tower to slide out. MU5210 unit: "5210 applies for launch." Baotou Tower: "5210, you can push out, please slide to the take-off runway 13." MU5210 crew: "Slide to take-off runway 13,5210. Got it."MU5210 crew: "Tower, 5210 requests to enter the runway." Baotou Tower: "5210, agree to enter the runway." MU5210 unit: "5210 understood." Then it took the crew more than one minute to complete the pre-departure checklist procedure-MU 5210 crew: "Tower, 5210 is ready, request to take off." Baotou Tower: "5210, agreed to take off."

Crash:

At that time, it was 8: 21, 9 minutes earlier than the scheduled departure time, and it is hard to say whether Chen Suyang's urging played any role. According to the division of labor, the pilot Wang Pin controls the plane, the co-pilot Yi Qinhui is responsible for the throttle and monitoring instruments, and the second pilot Yang Guang is responsible for the ground contact. Wang Pin: "Take-off thrust." Yi Qinwei: "Set, check." Wang Pin: "80 knots." (8: 21: 55), Wang Pin: "V1. Lift the wheel. " (At 8: 22: 12, the speed of the plane was 148 knots) Then Wang Pin took the pole backwards, and then the front wheel left the ground. At that time, the airspeed of the plane was 150 knots, and the thrust of the left and right engines N1 was 87.6%. After 3 seconds, the main wheel lifted off the ground, with airspeed of 161 knots, heading of 132 degrees and elevation of 6.2 degrees.
Wang Pin: "V2."
Yi Qinwei: "Positive climb rate."
Wang Pin: "Close the landing gear. Gee-"
But only two seconds after the main wheel was off the ground, the plane was in an abnormal situation. The steering wheel reached 30.3 to the right, the left slope of the plane was 9.6, the pitch angle was 12.6, and the angle of attack was 10.2. Immediately, the plane gave a warning of stalling and shaking. The airspeed was 165 knots, the left slope was 19.3, the radio altitude was 22.5 feet, the pitch angle was 13.2, and the angle of attack was 9.
Yang Guang: "What's the matter? What is this? !”
Wang Pin: "Take it with you!"
At the same time, he pressed the steering wheel to the right to 32.5 and pushed the rudder pedal to the right to 2.88.
Yang Guang: "I can't fly!"
Wang Pin: "Hey-"
At the same time, he pushed the rudder pedal further to 4.75 and increased the throttle to the maximum (the thrust of the left and right engines increased to 95.4% and 94.8% respectively at that time), but the effect was not good. After 3.5 seconds off the ground, the aircraft gave an audible warning that the pusher was working, and the pusher began to work, and the steering column was reduced from 5.75 to 0.22. The pitch angle is 15.5, and the angle of attack increases from 12.7 to 14.6 and begins to change in this approximate range, with a left slope of 29.8 and a heading of 121.5. The flight attitude of the plane began to waver.
Yang Guang: "What's the matter? ! What should I do? !”
Wang Pin: "Don't move, don't move the lever!" "
5.5 seconds after the plane left the ground, Wang Pin began to return to the steering wheel and rudder, and continuously pressed the steering wheel to the left and pushed the rudder to the left. But the pusher stopped working immediately. At that time, the pitch angle of the aircraft was kept at 18, the angle of attack was reduced to 10.5, the left slope continued to increase to 48.6, and then the left slope began to decrease. The flight attitude began to swing from side to side, and the crew gradually lost control of the flight attitude. Yang guang: "direction! Direction! " Wang Pin continued to press the pressure plate rapidly to the left and pedal the left rudder. Try to reduce the left slope to 17.1, the steering wheel to the left to 14.3, the rudder to the left to 11.72, and the aircraft pitch angle decreases from 18.2. Wang Pin: "Collect the oil! Collect oil! " Yi Qinwei: "Good, good." (After receiving the oil, the thrust of the left and right engines were collected to 88.4% and 86.3% respectively.) At this time, Baotou Tower found that the flight attitude of MU5210 was wrong, and immediately called the crew through the emergency frequency: "5210, Baotou calling." But the crew was busy dealing with the emergency and did not answer. At the eighth second after take-off, the captain continued to turn the left pressure plate of the steering wheel to 32.5 and the left rudder pedal to 8.63, which made the plane roll rapidly to the right, and the right slope instantly reached 68.6, with an average rolling speed of 39 per second. Then the pusher was started for the second time, which lasted for 3 seconds, reducing the elevation angle of the aircraft from 21.2 to 0.9 and the angle of attack from 21 to 3.7. The captain pressed the right pressure plate and the right rudder, and the plane began to roll to the left. At this time, the airspeed of the aircraft is 169 knots. Three seconds later, the plane rose to the highest altitude it could climb-180 feet (about 55 meters). At the 13th second after take-off, the pusher works for the third time, working for 1.5 seconds, and the pitch angle and angle of attack decrease again, but at this time, the aircraft begins to drop altitude and continues to roll to the left, with an average rolling rate of 32.5 per second. The maximum left slope reached 62.8. Wang Pin: "Come on! Come on! " Yi Qin Wei: "Good!"
Wang Pin: "What? What? Why? What is it? !” From 14.5 seconds to 16 seconds after take-off, the captain used a small amount of right rudder to reduce the right disk from 32.3 to 23.8, the left slope from 62.8 to 44, and the pitch angle from 10.4 to 3.9, but he was exhausted and could not see the sky. Wang Pin: "What is it? ! !” Yang guang: "hold on, calm down!" " "SINK RATE (big decline rate)! SINK RATE!” "PULL UP! PULL UP!” Wang Pin (to the co-pilot): "I told you to keep it!" Yi Qin Wei: "I can't do this, I can't pull it up!" " Fifteen seconds after take-off, the putter worked for the fourth and last time, but to no avail. From the 16th to 19th seconds, the captain still tried to save the plane. He kept the right pressure plate 31.9, but the left rudder pedal increased rapidly from 9.69 to 20.3. During this period, the pitch angle dropped rapidly from 3.9 to-9.8, the left slope increased rapidly from 44 to 89.6, and the flight attitude was almost perpendicular to the horizon. The plane fell hopelessly to Nanhai Park in Baotou, not far from the airport. Wang Pin: "Why? Why? " Then there was a panic scream in the cockpit voice recorder, which became the last voice record left by Bombardier CRJ-200 regional aircraft of MU5210 flight B-3072 of Yunnan Eastern Airlines. At 8: 22: 35, the Bombardier CRJ-200 regional aircraft of MU5210 flight B-3072 of China Eastern Airlines Yunnan Company crashed into Nanhai Park (coordinates 040 33' 02 "north latitude and 110 01' 01" east longitude) about 800 meters off the ground of No.13 runway of Baotou Erliban Airport, and the plane disintegrated after hitting the ground.
During the crash, the steel scaffolding of the bumper car amusement park in Nanhai Park was damaged, and the ticket booth, trestle and some cruise ships at the cruise terminal were destroyed. All 53 people on board were killed, and none survived. In addition, an old park worker who stayed at the cruise terminal and a mass who was swimming in the lake in winter were killed. The number of victims caused by this first-class flight accident reached 55.
