US Orders Engine Inspection after Deadly Airplane Accident

美國(guó)在致命事故后下令對(duì)飛機(jī)發(fā)動(dòng)機(jī)進(jìn)行嚴(yán)格檢查

United States airline officials have ordered inspections of some jet engines after a passenger airplane suffered a deadly accident this week.

在本周有一架客機(jī)遭遇致命事故之后，美國(guó)航空系統(tǒng)官員已經(jīng)下令對(duì)一些噴氣發(fā)動(dòng)機(jī)進(jìn)行檢查。

The Federal Aviation Administration (FAA) announced the order late Wednesday. However, the engine's manufacturer and European officials had called for careful inspections several months earlier.

美國(guó)聯(lián)邦航空管理局周三晚些時(shí)候發(fā)布了這項(xiàng)命令。然而，該發(fā)動(dòng)機(jī)的制造商和歐洲官員早在幾個(gè)月前就要求對(duì)此進(jìn)行嚴(yán)格檢查。

The engine on a Southwest Airlines plane blew apart on Tuesday. Debris from the explosion broke a window. A woman sitting next to the window was partially sucked out of the plane. She later died of her injuries. The plane, which was traveling from New York to Dallas, Texas, made an emergency landing in Philadelphia.

美國(guó)西南航空公司這架飛機(jī)的引擎在周二發(fā)生了炸裂。爆炸產(chǎn)生的碎片擊中了一扇窗戶，坐在窗邊的一位女士身體被部分吸出飛機(jī)。她后來傷重不治。這架從紐約市飛往德州達(dá)拉斯市的飛機(jī)在費(fèi)城進(jìn)行了緊急降落。

Investigators said a blade in the engine broke off during the flight. They said the blade showed signs of metal fatigue — very small cracks that can break apart under stress.

調(diào)查人員表示，飛機(jī)發(fā)動(dòng)機(jī)的一扇葉片在飛行期間發(fā)生了脫落。他們表示，該葉片出現(xiàn)了金屬疲勞的跡象，這種非常細(xì)微的裂紋在壓力下可能會(huì)斷裂。

In 2016, U.S. officials also blamed metal fatigue on a similar engine failure on another Southwest Airlines plane in Florida.

2016年，美國(guó)官員還將美國(guó)西南航空公司在佛羅里達(dá)州另一架飛機(jī)發(fā)生的類似發(fā)動(dòng)機(jī)故障歸咎于金屬疲勞。

The incident led the manufacturer CFM International to recommend last June that airlines carry out inspections of fan blades in its CFM56-7B engines.

這起事故導(dǎo)致去年6月發(fā)動(dòng)機(jī)制造商CFM國(guó)際公司建議航空公司對(duì)該公司生產(chǎn)的CF56-7B發(fā)動(dòng)機(jī)的葉片進(jìn)行檢查。

CFM International is a joint business of GE Aviation and France's Safran Aircraft Engines. The company says over 8,000 CFM56-7B engines are currently in use on Boeing's 737 airplanes.

CFM國(guó)際公司是由美國(guó)通用航空和法國(guó)賽峰飛機(jī)發(fā)動(dòng)機(jī)公司組建的合資公司。該公司表示，目前有超過8千臺(tái)CFM56-7B發(fā)動(dòng)機(jī)在波音737飛機(jī)上使用。

Robert Sumwalt is chairman of the National Transportation Safety Board. He said, "Engine failures like this should not occur."

美國(guó)國(guó)家運(yùn)輸安全委員會(huì)主席羅伯特·桑沃特 (Robert Sumwalt)表示，“這種引擎故障就不應(yīng)該發(fā)生。”

But he advised it was too soon to question the safety of the engines or the Boeing 737s. The plane is the most popular commercial airplane in the world.

但他表示現(xiàn)在質(zhì)疑發(fā)動(dòng)機(jī)或波音737飛機(jī)的安全性尚為時(shí)過早。這種機(jī)型是全球最受歡迎的商用飛機(jī)。

On Wednesday, the FAA said it will require inspections of fan blades on CFM56-7B engines after they reach a certain number of takeoffs and landings. Blades that fail inspection would need to be replaced.

美國(guó)聯(lián)邦航空管理局表示，該局將會(huì)要求對(duì)起降達(dá)到一定次數(shù)的CFM56-7B發(fā)動(dòng)機(jī)的葉片進(jìn)行檢查。未通過檢查的葉片需要更換。

Southwest Airlines announced its own program for similar inspections of its 700 planes over the next month.

美國(guó)西南航空公司宣布了自己的計(jì)劃，將在下個(gè)月對(duì)該公司700架飛機(jī)進(jìn)行類似檢查。
