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.

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!
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.

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.

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.
