JohnT Posted February 20, 2021 Share Posted February 20, 2021 Luckily no one hurts but a United Airlines Boeing 777 lost on engine which shed parts and went on fire. Video of an alarming loose engine on fire in the BBC report here https://www.bbc.co.uk/news/world-us-canada-56141673 Still good news that it got down ok but not what you want to see out of the window of your aeroplane Link to comment Share on other sites More sharing options...
PhantomBigStu Posted February 20, 2021 Share Posted February 20, 2021 (edited) Indeed, testament to the design that it’s almost trivial for it to lose an engine, be interesting to see the cause, dunno about the engines originality but the airframe is 777 number 5 with over 26 years on the clock Edited February 20, 2021 by PhantomBigStu 2 Link to comment Share on other sites More sharing options...

Let's let the NTSB/FAA/Boeing/United do their jobs and find out exactly what happened. Well done to the crew for getting everyone back down to terra firma without further drama and no reported injuries. 2 Link to comment Share on other sites More sharing options...
Hook Posted February 21, 2021 Share Posted February 21, 2021 The same happened to a 747 over the Netherlands yesterday: https://www.aviation24.be/airlines/longtail-aviation/boeing-747-loses-parts-after-take-off-from-maastricht-diverts-to-liege-two-people-injured/ Cheers, Andre 1 Link to comment Share on other sites More sharing options...

If I was one of the passengers, the first thing that I would want to do is shake the pilot's hand.......after getting some clean underwear of course.

bentwaters81tfw Posted February 21, 2021 Share Posted February 21, 2021 That's a neat roof aerial, the guy needs to get it painted. Lucky there were no serious injuries in either case. Now.....things run in threes....... Link to comment Share on other sites More sharing options...

TallBlondJohn Posted February 21, 2021 Share Posted February 21, 2021 Boeing had probably just finished all the PE. That guarantees a drop every time. Link to comment Share on other sites More sharing options...
Mike Posted February 21, 2021 Share Posted February 21, 2021 Saw a brief video from someone on the ground watching the first one go over their house. Must have been pretty scary, but when an aircraft engine failing is newsworthy, it's a testament to the actual robustness and reliability of these things today Both landed safely, which is the best part 5 Link to comment Share on other sites More sharing options...

I'll bet there are a few marks on the escape chutes that'll take more than a couple of bottles of Vanish to remove 😊 1 Link to comment Share on other sites More sharing options...

noelh Posted February 22, 2021 Share Posted February 22, 2021 While both are engine failures. That's the only thing in common. Different engines types , different airframes. The 777 lost the inlet and much of the cowlings. It's hard to tell from the video if any of the fan blades are missing. If so then that's a possible reason the inlet was ripped off. On the 747 it looks like the cowlings remained in place but a lot of turbine blades were scattered about. I've seen the results of one turbine blade failing and taking out most of the rest of the hot section. Not pretty. Time and investigation will tell.

KevinK Posted February 22, 2021 Share Posted February 22, 2021 Current update: Japan's Civil Aviation Bureau, and the FAA have suspended operations of B-777 aircraft powered by Pratt & Whitney 4000-112 engines. This is a small proportion of the total 777 fleet. In the US, only United appears to be an operator of the subtype. Link to comment Share on other sites More sharing options...
busnproplinerfan Posted February 22, 2021 Share Posted February 22, 2021 Interesting, we maybe not is how the first thing medias all say is the age of the plane. Meanwhile planes are constantly looked at and overhauled. Well vast majority are. Wonder if the guy with blade in the roof of the car will get to keep it. Gives the car some character.

JohnT Posted February 22, 2021 Author Share Posted February 22, 2021 BBC reporting that all triple sevens with the Pratt & Whitney engine fit are recommended grounded. It affects 3-4 airlines only. Link to comment Share on other sites More sharing options...

That vibration along with any damage from the departing blades could have caused the inlet to separate. Incidentally that thread title in pprune isn't strictly correct unless the definition of an uncontained failure has changed since my time. The media of course is on the case linking it to the 737 Max issue. 🙄. Then the age of the aircraft. Which is irrelevant to the age or maintenance history of the engines. The fan blades could be brand new. Engines don't stay with one airframe or even one airline. You'd think the media in general would educate themselves on the topic? 1 2 Link to comment Share on other sites More sharing options...

But is this actually newsworthy? I guess engine issues happen with 1000s daily flights. I guess media will report any issue with engines and Boeing they can get hold of... it makes news= money for them.... It is just that the 777's issue was spectacular and let to a partial fleet grounding. Let's hope its is not systematic, but I doubt a 757 shares a lot with the 777 but the manufacturer! 1 Link to comment Share on other sites More sharing options...

busnproplinerfan Posted February 24, 2021 Share Posted February 24, 2021 Even though he's not an official NTSB. this guy "Blanclolirio" gives a good account of the situation. He is a pilot and does explain things pretty good. Gives a different perspective than regular media that don't always know much about aircraft. https://www.youtube.com/watch?v=EwNCCrjMmeg https://www.youtube.com/watch?v=jh4727krwH4 1 Link to comment Share on other sites More sharing options...

I started watching him when he talked about the last Snowbirds crash so he not only talks about U.S. crashes but everyone. 2 Link to comment Share on other sites More sharing options...
