“We reviewed all available safety data following yesterday’s incident,” FAA administrator Steve Dickson said in a statement. “Based on the initial information, we concluded that the inspection interval should be stepped up for the hollow fan blades that are unique to this model of engine, used solely on Boeing 777 airplanes.”

United Airlines says it’s voluntarily grounding 24 Boeing 777 aircraft that use the 4000-series Pratt & Whitney engines and expects “only a small number of customers to be inconvenienced.” Japan’s Civil Aviation Bureau ordered Japan Airlines and All Nippon Airways to remove their aircraft with the same engines from service; JAL operates 14 and ANA has 19, according to Reuters.

如果是bird strike搞成的turbine blade飞了,可以理解

毕竟是上升的时候废掉的,这时候rpm最高,也是离心力最大
那得是一个巨型bird

(CNN)A United Airlines flight bound for Honolulu was forced to return to Denver International Airport Saturday after suffering an engine issue, a spokesperson for the airport told CNN.

The flight returned safely to the airport around 1:30 p.m. local time, the spokesperson said.

That was about 20 minutes after police in Broomfield, Colorado, said via Twitter that they had received reports that an airplane flying over the Denver suburb had engine trouble and had "dropped debris in several neighborhoods around 1:08 p.m."

"No injuries report at this time," the tweet added.

Additional tweets from police said debris landed in a Commons Park and the Northmoor and Red Leaf neighborhoods of the city, which is about 25 miles north of Denver and 30 miles east of Denver International Airport.

Authorities have yet to definitively connect the two incidents, but the Federal Aviation Administration confirmed in a statement that a Boeing 777-200 safely returned to the Denver International Airport after "experiencing a right-engine failure shortly after takeoff."

"The FAA is aware of reports of debris in the vicinity of the airplane's flight path," the statement said.

CNN has reached out to United Airlines for additional information.

发动机是普惠PW4000,目视风扇没损坏。风扇外壳机舱一侧无破损。

昨天电视里专家说,叶片上中空的,内部的损伤从外面看不到,等看到时侯已经晚了。。。。

如果把叶片全部更换,目前生产能力不够,短期内换不过来。

以前看过报道,中空的应该可以用x-ray检测

是,但X-ray检测应该算比较大的保养工作了。

普通保养时肉眼看不到。
