The old lady put money in the middle of the passenger car
According to the local service department of China Southern Airlines Shanghai Branch, there are four people in the group, including the old man and his daughter's son-in-law. Due to the inconvenience of movement, the ground service personnel sent four people off the plane.
It is understood that the old man threw coins at the engine in the middle of the car, but the staff who checked in under the elevator and greeted the guests at the door of the cabin failed to find any change. Fortunately, the old lady's coin throwing was seen and reported by the passengers behind her. Then, nearly 150 passengers got off the plane and waited, staying at the airport. The airport police arrived at the scene to investigate. According to the captain on duty of cz380, if the coin is sucked into the core Department of the engine, it is likely to collide with the high-speed rotating blades of the engine, which is very easy to cause the engine to surge, stall or even stop.
The flight took off via Nagoya, Japan, via Shanghai and ends in Guangzhou. This article is compiled by sihai.com.cn and reprinted with the source. The original link: http://www.4hw.com.cn/life/
Coin drive
The old lady told the police to coin for blessing
Later, Shanghai police reported that after investigation by the International Airport Branch of Shanghai Public Security Bureau, Qiu (female, 80 years old, no history of illegal crime and mental illness) said he tossed coins to pray for flight safety.
After security checks, police found nine coins at the scene, one of which landed in the engine and the rest on the nearby ground.
In order to ensure flight safety, the maintenance department of China Southern Airlines carried out a comprehensive inspection of the aircraft's engine. By 16:53, the engine was overhauled and the aircraft could take off safely. The flight took off at 18:16 to Guangzhou.
At present, the passengers involved and their accompanying passengers are still under public security inquiry. After China Southern Airlines assisted some passengers of the original flight to change their visas, other passengers continue to take the flight to Guangzhou. The situation is under further investigation. This article is compiled by sihai.com.cn and reprinted with the source. The original link: http://www.4hw.com.cn/life/
In this regard, China Southern Airlines issued a notice to remind the majority of passengers that they should abide by the relevant laws and regulations of civil aviation when flying, and forbid any act endangering aviation safety.
What are the serious consequences of foreign matters in aircraft engines
Experts said that coins are wear-resistant steel. Once they enter the engine, many rotating parts will be damaged during high-speed operation. When the air flow is inhaled from the front to the back, the fan will be further damaged, or even enter the blade combustion area, or even lead to the overall scrapping of the engine. I really want to thank the passenger who found the abnormality, and report in time.
Then throw the coin into the engine how much is it worth. This is actually a very difficult account. Today, the engine needs to be disassembled if it's difficult to find out. It needs to be installed and tested again. The maintenance of the aircraft is similar to that of the 4S shop. There are many ways to do it, and it won't cost a lot of money. If no one reports it, one or several blades in the engine will be damaged as soon as the engine starts and jingles, starting from $10000, excluding the labor cost.
There is an analysis of engine failure caused by foreign matters in the runway on the official website. It is believed that the maintenance cost of engine damage caused by such accidents can reach up to 20% of the price of the engine. If the card is the upper limit, the cfm56-5b engine is thrown into the coin. The new price is about 50 million RMB. So the claim for '8 million' is probably from here.

Doesn't it mean that the engine has to withstand the impact of birds? Why is a coin so close to the enemy? Indeed, before the engine is put on the market, it has to go through tests including swallowing birds, swallowing hailstones, etc. after swallowing, it must be safe, the fragments can't fly around, and the jargon is tolerance can't fail. But it doesn't mean you can work safely. In fact, a little hard things will damage the engine. The track foreign body mentioned above, scientific name FOD (foreign object debris). Anti FOD is the most important daily work in every airport.
