B777 engine - Denver

Post by mik »

Another issue with a Boeing aircraft, but specifically an engine issue - Pratt & Witney unit.

All twin-engined passenger jets can land safely with only 1 engine, so whilst the damage and fire looks really dramatic - it shouldn’t cause danger to life unless there is other consequential damage. I only saw images today of the fuselage breach. :o I have many times sat in the seat beside the engine that doesn’t have a decent window due to the fuselage reinforcement in that area should a fan blade break loose.... and have often wondered how effective it would be. I guess the cargo area doesn’t need, and therefore doesn’t get the same reinforcement.

It just goes from bad to worse for Boeing, doesn't it?
If you get all wobbly-lipped about the opinion of Internet strangers, maybe it's time to take a bath with the toaster as you'll never amount to sh1t anyway.

Definitely won't help with their brand reputation.

I love the caption on this video on the BBC: "I just knew something was wrong."

Really? I don't know how you guessed! :lol:

Proper job blowing all that cowling off. Am I correct in thinking that Boeing also own Pratt and Witney, so technically an in-house engine?
Cheers.

Front cowl ended up in someone’s front garden

What those Twitter pics don’t show is the close up front view of the fan blade failure- one snapped and took a piece of a second

IIRC the cowling is meant to contain a turbine blade failing (I’m sure I heard it on some program) so that’s also a failing of the cowling too.

Edit - this is what is meant to happen

This is true.

Will be interesting to see the report. I suspect something impacted the fan blade - they are immensely strong. Maybe the resulting imbalance when these were lost shook all the engine cowlings off as it slowed?

Like in this earlier test footage

Yep. My best mate works in the aerospace engine component industry and said its a double failure. Occasionally things fail but resultant damage to the fuselage is not acceptable and someone is in the shit.

Didn't an engine fail on a plane a year or two back and a lady in the cabin was killed by flying parts?

Wikipedia has a list of Notable uncontained engine failure accidents, some of them are pretty grim:
"TAM Flight 9755: a Fokker 100, departing Recife/Guararapes–Gilberto Freyre International Airport for São Paulo/Guarulhos International Airport on 15 September 2001, suffered an uncontained engine failure in which fragments of the engine shattered three cabin windows, causing decompression and pulling a passenger partly out of the plane. Another passenger held the passenger in until the aircraft landed, but the passenger blown out of the window died."

Presumably it's Pratt & Whitney rather than Boeing who are at fault here?
