 The US and Europe will detect 680 aircraft engines urgently to prevent the danger of the airliner.


The US and European civil aviation regulatory authorities ordered 20 days to detect about 680 aircraft engines in the next 20 days in order to prevent another danger. On 17 July, a Boeing 737-700 aircraft engine blade dropped off and broke the porthole, causing a female passenger to be sucked out of the cabin. The flight No. 1380 was originally scheduled to fly from New York to Dallas, and then forced to make a landing at Philadelphia International Airport. The US National Transportation Safety Board said preliminary investigations showed that engine fatigue may be the cause of the accident. It is understood that Boeing 737 is one of the most popular and heavily service airliner in the world. The engine, which is CFM56-7B, is one of the most frequently equipped engines of the 737 series, which is made by the United States General Dynamic Corp and the CFM International Corporation, a joint venture of France peak group. The Federal Aviation Administration, 20, said, this unsafe situation may exist in the same design of other products, so it is necessary to complete the emergency test within 20 days, so as not to repeat the similar events. The latest measures issued by the Federal Aviation Administration and the European Union aviation safety agency are aimed at aircraft engines that have served more than 20 years or more than 30 thousand cycles, with an estimated global number of around 680, of which about 350 in the United States. Reuters introduces that the so-called operation of a cycle refers to a complete journey from take-off to landing. In the 17 day of the planes dangerous situation, the malfunctioning engine has been running for about 40 thousand cycles. According to the surviving passengers, about 20 minutes after taking off, the left wing engine made a loud noise, and one of the porthole was knocked out by the fluttered blade, and the cabin quickly lost pressure. At about 9900 meters high, a female passenger was sucked out of the cabin. A few brave men pulled her back from the window, but eventually the woman was killed. In August 27, 2016, a CFM56 engine of another Boeing 737 of Southwest Airlines had a similar danger in the flight. A blade fell off, breaking the left wing, the fuselage and the tail. The plane landed in Pensacola, Florida. Investigators also found signs of metal fatigue.
