On the morning of August 24, 2019, a 747-400 freighter at Changbei International Airport in Nanchang slid off and took off due to unexpected circumstances. Since the aircraft weighed more than 400 tons, the huge braking energy made 16 tires. The 14 of them were deflated, and the plane was on the runway and could not move.
When the crew was evacuated, the emergency inflatable slide of the upper cabin was activated to escape.
Since there is only one runway at Nanchang Airport, the airport can't run at once, the planes entering the port return, and the planes leaving the port are delayed. However, Nanchang Airport is temporarily closed, and all the aircraft stop taking off and landing.

The best solution is to transfer aircraft tires from the field to Changbei. The airport is being replaced.
The upper 747 aircraft on the runway, due to the huge braking energy, is accumulated on the brake pads and transmitted to the tires at high temperatures, causing the tires to overheat, start the protection device, melt the hot melt plugs, and the tire deflated aircraft cannot move.
However, at this time, the entire airline in East China with short runway takeoff and landing capability, complex airport operation level and cross-regional flight experience is Jiangxi Express Express Co., Ltd., which is based in Nanchang Changbei Airport.
