6.
aircraft loading and center of gravity of this situation are set out the maximum amount of flights available to 14,248 kg. A total of 65 passengers (including 64 adults, baby 1), weight 4616 kg; loaded 58 bags, weighing 750 kg; loading cargo 29, weight 554 kg; loading message 13, 12 kg. Total load 5932 kg or more. Compared with the maximum available payload, load 8316 kg.
aircraft loaded in accordance with no oil center of gravity should be at 8.5%? 28%, the actual was 17%. Takeoff weight of 7.5% should be the focus? 28%, actual 17.2%, the center of gravity are in the best position to meet the requirements.
thus proved that there is no business of overloading the machine and load balance.
7. unlawful interference
(1) according to the scene, interviewed witnesses and found, before landing the aircraft found no fire or fire, you can rule out the possibility of fire after the landing.
(2) the flight of all passengers, baggage and cargo are required for a security check and found no prohibited items, exclude the possibility of inflammable and explosive dangerous goods installed.
(3) by extracting samples for testing and found no explosives on the wreckage residues, but also did not find traces of an explosive formed.
(4) by visiting some of the survivors of the crew members and passengers, to exclude acts of unlawful interference with aircraft flying there.
8. witnesses to reflect the situation
(1) At that time the aircraft on the tarmac crew then reflected, aircraft landing from south to north the rain very, very close. When the aircraft to go after landing from north to south, heavy rain, it was dark and visibility is poor, high altitude aircraft, speed, big, sinking fast.
(2) According to 3 minutes before the plane landed in Shenzhen Airlines Flight 822 captain reflected: Shilong radar point of view there is a flat state to the
According to the machine 5 minutes after the first ground floor of the Air 1305 flight crew reflected in terms of the airport from the south end of the radar thunderstorms, heavy rain cut into the encounter after the blind down, saw the runway 800 feet out of the cloud, rain is relatively large, As water on the runway, landing lighting is not good, can not see the ground, only to see the runway lights * close rate to control aircraft.
(3) 2925 crewman reflect: the first ground, sitting on the door of the three flight attendants after the seat was broken and the aircraft frame the central 17,18 ranked Lee raised arched, raised floor of the plane split, window deformation, part of the roof off, the cabin burning smell, instant power, cabin luggage rack some of the items after the drop.
Analysis
(1) 2925 Unit five-sided approach in the process, before the decision height, aircraft attitude, flight path, glide path to maintain all normal, but the speed is too large (142.5 nautical miles / when normal speed of 136 nautical miles / hours). Unit introduced the report to see light, then they reported seeing the runway. Decision height, because the aircraft was flying in heavy rain, the unit decided to
the night flying experience heavy rain, poor visibility, runway, water, lighting is not good, to see the ground is not clear. In this case, the unit did not go around to take decisive measures to break the rules, continue to approach descent, lost the initiative, delaying the timing, which is the main reason causing the abnormal landing, and the ultimate cause of the accident's cause.
(2) when the aircraft is too close to the station after the height of 170 feet, the cockpit of a that
height of 50 feet into the runway, due to Ground (stop Boeing 737 degree angle of -0.79 to -1, according to data record decoding data, grounded in the attitude of the aircraft between -1.4 to ten 1.7). 4 seconds before the aircraft ground decreased rate of 9? 3 feet / second, grounded vertical overload of 2.49G, and produce the first jump, the aircraft damaged.
aircraft grounded the first 2 to 3 seconds, cockpit voice recording has been called Too late to see the pavement, there is no ground to maintain the correct posture is a hard landing caused the aircraft the direct cause of jumping.
(3) aircraft, the first jump, the height of 5 feet, grounding vertical overload 1.9G, not determined to close the throttle unit. N1 RPM increases and decreases irregularly, the same time, putting action. The disposal of the error, resulting in continuous production of the aircraft and two jumps. The second jump 7 feet, grounding vertical overload 2.54G, the third jump 13 feet. Containing three successive jumps and more than cause serious damage to the aircraft structure.
(4) plane after the third jump as high altitude, coupled with the night rain, the unit has not identified the aircraft in case of damage to the program around.
the damage control system, complex flight, the aircraft to 183 sea miles / h speed, the small elevation of 2 degrees off the ground (the aircraft off the ground, the crew felt the stick is . Serious damage to the aircraft after the crew go around and give a second landing potential problems.
(5) missed, the cockpit a Aircraft damaged after two laps in the sky, the unit decided to close the reverse landing north to south. Due to heavy rain has not stopped, the aircraft control system failure (the change in the steering column and the elevator deflection angle obviously does not match the large bar, a small elevator in the yaw angle), although the crew pull the stick before landing in the end, but did not change the aircraft large angle is bent posture, the last aircraft is still under the 7.56 degree angle of depression, 227.5 sea miles / h speed, the decrease rate of 41 feet per second, with 3.2 degrees hit the ground after the disintegration of the left slope, fire.
accident concluded in the final approach the aircraft
encountered heavy rain, the unit not see the pavement in case of violation of the provisions of the blind down; the judge allowed a high degree, resulting in the ground plane did not maintain the correct posture, causing heavy landing jumps, combined with the captain disposal error is caused by the direct cause of major accidents. Missed, due to the aircraft has been seriously damaged, part of the control system failure, the unit can not control the landing attitude, so that the second aircraft landed, taken off the depression of the touch the ground at high speed, causing the disintegration of the aircraft crashed. This is a man-made causes of major accidents.
