U.S. FAA to require strengthening key part on Boeing 777 engine

The head of the Federal Aviation Administration said on Wednesday the agency is going to mandate strengthening a key engine part on Boeing 777-200 planes equipped with Pratt & Whitney (PW) engines like the one involved in an emergency landing in February. ( More...

Yea the triple seven has no proven history of flying billions of miles with no major accidents or deaths - the safest aircraft to tour the world for decades

Another Band-Aid approach instead of addressing the engine fand blade fatigue failure, the root cause of the 'injury"..!

My apologies for the fan blade typo!

Another example of a writer who should not title an article. There is no such thing as a Boeing 777 Engine... it is the Pratt & Whitney 777 Engine... What is wrong with these writers... Certainly they know how to spell, wish they put as much thought in to what they were really trying to say! MORONS

Dude, your ignorance doesn't make them wrong. The cowling is part of the aircraft. P&W don't make cowlings. So since the cowling failed when the engine failed the cowling needs to be fixed. The engine will get its own reports and mandated actions, and they will probably apply to engines that aren't fitted to 777s. So how would you have phrased this? Because I bet most people would say that the common cowling that surrounds the engines on Boeing 777s is part of the Boeing 777 engine installation. If you have trouble parsing that then that's your lack of understanding of English.

Wow ya think and its what should happen anyway due to the fact the part failed. Nothing new about your or the other post.

Why is this a Boeing Article and not a Pratt Article.. Pratt is at fault here not Boeing! Writers have no clue how to write aviation articles.. they should not even try!

Interestingly enough, the person who said, in the quote in the article, that the cowling was an issue is an ATP-rated, former airline pilot and the FAA administrator. Fair's fair, let's not blame the writer unless we know that the quote was incorrectly cited.

No, P&W don't make cowlings. This is a failing in the cowling that happened when the engine failed. That resulted in a 777 that could not maintain altitude in at least one case. So Boeing has to fix the housing they make for the engine, which came apart under vibration.

To answer your question: Boeing killed 346 people to save some money. It will always be about Boeing because they build the planes for profit. Boeing is no one's friend anymore, funny how greed does that.

LOL! Harassing you? HAHAHAHA. So precious.

IMHO : the bit about reinforcing a cowling makes headlines, but ignores the root problem. The failures have happened because the 23-pound hollow blades on the PW 4077 are wearing out, difficult to inspect, and so far NOTHING has changed to remedy the issue on these engines.
Sparkie624 is spot on. This is media bias - bash Boeing.

The cowling failed when the turbine liberated a blade. This isn't specifically about the cowling.

From the article:
"The FAA in February ordered immediate inspections of 777 planes with PW4000 engines before further flights, after the National Transportation Safety Board found a cracked fan blade on the United engine was consistent with metal fatigue."

The fan blade is the issue. It throws the engine out of balance, and that destroys the cowl.

Fixing the cowling won't fix the problem. Another goofy article.

The fan lost a blade, not the turbine. The turbine is the hot part. So you have fan, then compressor, then combustor(s) then turbine. Turbine blades are relatively small and don't weigh much. The reson they need to fix the cowling is that in at least one case when the cowling failed the resultant drag made the aircraft incapable of maintaining altitude on the remaining engine. Boeing changed the part that failed in the cowling from aluminum to carbon fiber after the blade off tests. The tested version survived. Read the report on United 1175.

Boeing deserves every bit of bashing for their greed. They killed 346 people rather than update training manuals.
And no one is facing jail time. Boeing is just too toxic.
