Zhejiang News Client Reporter Zhang Fan, Sun Yan, Shi Yuxiang, Hu Hao Liu Yongtuo This morning, a cargo plane of Zhejiang Changlong Airlines felt something abnormal during takeoff. Then it was found that the right main wheel tire of the landing gear burst. The airport immediately

The aircraft descends and prepares for landing

The reporter noticed that compared with recent similar incidents at home and abroad, cases of aircraft landing gear tires damaged and ruptured have occurred frequently.

On June 11 this year, the tires of Tiger Airlines flight TR2934 from Singapore to Haikou were damaged after taking off. The plane hovered over Haikou for many circles, and the test landing failed. However, with the efforts of the crew, the plane successfully landed at 11:04 that night, and 178 passengers and crew escaped.

On April 21 last year, Malaysia Airlines flight MH192 took off from Kuala Lumpur International Airport and planned to fly to Bangalore; but after the plane took off, the pilot found that the tire on the right side had a blowout, and the plane quickly returned; in the end the plane was able to successfully land.

On July 29, 2013, a Boeing 737 passenger plane carrying 137 passengers exploded when landing at Chicago O'Hare International Airport. Passengers evacuated the plane through a suspended vehicle. The accident caused no casualties.

On July 12, 2011, a Denmark Boeing 737 passenger plane made an emergency landing at Denmark Billon Airport due to a tire burst. Airport firefighters and ambulance personnel were on standby at the scene. Fortunately, the plane landed safely and no casualties were caused.

The plane descends and prepares for landing. Experts: Smooth landing after a tire blows can be seen that the pilot has a high level. Foreign objects are more likely to cut the tires

Why do the planes have multiple tire damage accidents during take-off and landing? Mr. Guo, an industry insider, said that tire bursts are more common among all kinds of aircraft failures. The tires will be impacted at high speed during the landing process. At the moment the tire touches the ground, the contact point is stationary relative to the ground, but other parts of the tires are still moving at high speed with the aircraft and need to bear huge pressure.

This morning, Long Dragon Airlines cargo pilot also successfully landed in a burst of tires. Regarding this forced landing, a senior domestic pilot posted on Weibo, describing that the tire blowout of the plane is as dangerous and difficult to control as a "highway car tire blowout".

Liu Yi, chairman of the Liaoning Aviation Sports Association and senior pilot, believes that although the plane lands smoothly, it is very difficult to land in such a situation. It is not easy to implement such a smooth landing, which shows that the pilot's level is very high.

"The tire on the right side of the landing gear bursts, and a right-to-right force will be generated when landing. This force is very large when the aircraft hits the ground, and the operation requirements for the pilot are very high."

Liu Yi said that the pilot needs to control the aileron and rudder in the shortest time, and by controlling the aileron to offset the force deflecting to the right, and by controlling the rudder, the aircraft will be taxied to the left and maintained balance.

" These two operations must also be well-known, because if you are not careful, the plane will rush out of the runway or make a 180-degree rotation, and the consequences will be unimaginable."

Talking about the reason for the tire blowout of the Longlong Air Cargo plane this time, Liu Yi said that the most likely thing is that there are foreign objects on the runway and taxiway of the plane, and the foreign objects cut the tires; in addition, it may also be caused by the damage to the wheel hub structure and improper braking. "But these are just speculations, and everything will have to wait for the cause of the accident to be released before it can be finalized. ”
