Flying friend news, the Airbus A320 series of "shark winglets" recently caused trouble. It was found to cause wing fatigue cracking, and the European Aviation Safety Agency previously issued a directive saying that all A320CEO series should be inspected; On January 25, it was updated that the entire A320NEO series should also be inspected - causing a "big disaster"!

The Airbus A320 family is now the world's most popular single-aisle mainline airliner, with more than 3,000 in the air at any given moment, with an estimated total of more than 7,000 in service. It is available in the new A320neo and the old A320CEO, each of which is divided into three models: A319, A320 and A321, and a small number of A318 ...... the old oneVery informative.
Winglets are fuel-efficient inventions, and the winglets of the Airbus A320 are originally small. But Boeing made it big in the 737ng era, and Airbus followed suit, calling it "sharklets". But now some customers have discovered that the sharklet will cause a crack in the bottom of the wing, roughly between the wing ribs 13 and 33 - could it be that the winglet is "too heavy"?

All A320neo family aircraft are equipped with Shark winglets. On the A320CEO, it is only available on later models. Some of the mid-range A320CEO models were fitted with different processes and were included in this inspection. The author made a rough estimate that there are about 5,500 aircraft involved worldwide - what to do? Back in time?
That's not Airbus' only trouble at the moment. Due to the quality defect of the secondary turbodisk of the PW1100G engine, a large number of A320neo are now grounded for maintenance around the world, and Airbus may face a high amount of compensation. Moreover, the A321 passenger-to-freighter conversion project has also had problems recently, and cracks have been found in 2 A321P2F converted by Lufthansa in Elbe, Germany.

Wing cracks can develop into wing fractures if left untreated. But at the moment, it seems that it is not serious enough to be that serious. Some people say that it is just a crack in the skin and not a crack in the skeleton, and some people say that it is not necessarily cracked, but the probability of cracking is not high; It is also said that the crack occurs at the bottom and can be detected by sight, and that a fool would drive a plane with a crack to the sky......
But at the same time as the Boeing 737 had serious quality problems, Airbus also reported these incidents, which was chilling. These two are the main manufacturers of human air travel, and now they are not better than whom, but more wrong than whom? Can't you two good good made, day day up?
