Boeing 777 engine fire.

[Illaveago]

The inconel/kevlar/tungsten carbide (combinations thereof, or delete as applicable) cover shroud is designed to do precisely that - blade failure containment. Have a browse on Pratt and Whitney's own website.

A lot of Boeing production was moved from Seattle to North Carolina (or South, I forget which) and concerns about lesser quality from that plant are well documented in the public domain - poorly fitted fasteners, incorrectly routed cabling, lots of little things adding up to a big bucket of creaks and rattles. Not enough to fail certification, but enough that these aircraft are difficult to sell once they're 5 or more years old. Be interesting to see where this one was constructed.

The American Government cancelled an order for aircraft due to the quality of workmanship , tools and swarf from drilling left inside the wings .

Not a view you see very often, but a good illustration of how light and well-engineered aircraft components are.

That cowl ring is around 11 feet in diameter (almost as wide as the fuselage of a 737) and yet it's partly supported by that flimsy tree branch:

View attachment 575130

And also still relatively the right shape, given it's recent experience...

There’s been a few in depth articles about the decline of Boeing, a common theme being the rise of the Bean Counters over the engineers, and the “ capture” of the safety certification processes from the regulators to “ in house “ and the shenanigans that led up to the tragic loss of life in the two 737 Max crashes.
Ryanair had a lot of the 737 Max on order, and of course their version had been adapted to fit extra rows of seats to bring the capacity up to 200 passengers.

Read the Micheal Crichton book 'Airframe'

It's a rivetting read, & explains a lot

That the shroud. Made from inconel and incredibly tough, supposed to contain the shrapnel in the event that the turbine blades let go, yet when it was really needed it fell off...

Be interesting to see if its a design issue, a maintenance concern, or because these jets have been sta ding largely idle and unused.

The article I read said the plane was 20+ years old, so, maintenance rather than design, I would have thought. Indeed, the fact that despite the engine failure, the aircraft landed safely would suggest good design, surely?

 

[BoldonLad]

The 777 is rated to fly for 330 mins on one engine. If this had happened halfway (180mins) across the Pacific on the way to Hawaii, it could still have landed on a good day.

Good to see a positive view!

Surely, the real good news here is, despite the failure of the engine, the aircraft landed safely ?

Agree - impressive calm & application of training.

I used to live under the final approach for Manchester Airport; bits of plane landed in people's garden occasionally in the eight years I was there.

In the aviation industry, those incidents are known as BFOs.




Bits Falling Off.

Aren't some of those BFOs also known as "blue ice"?

I used to work in a team that programmed the engine control systems for Pratt and Whitney executive jet engines. We had one issue whereby an engine sped up, then slowed down too much when coming into land. Turned out the drainage hole was drilled the wrong side of the box. The circuit board had a waterproof coating, but persistent dripping over time had worn a patch of the coating away.

If you are not of a nervous disposition, it's worth having a look at this website.....

If you are a bit apprehensive about flying, don't.

That's when they must regret doing away with the flight engineer on board. Send him out there with some gaffer tape and a few zip ties and they would be fine to continue to Honolulu.

it could still have landed on a good day.

But if it was raining............

 

[ebikeerwidnes]

The UK has banned all 777s with those engines - the FAA in the USA didn't - but then Boeing said they should all be grounded anyway

The people in Boeing must feel the Gods are upset with them!!!

I'm not an engineer but look at that picture i'd definately say something is not right 😂

Im sure someone might say...'but it was alright yesterday ???'
(This happens a lot to me...something breaks down and the inevitable, disbelieving, genuine comments is as above)
