Air Canada emergency landing at YYZ

[BOAC]

loma - you did understand that bit referred to hawker, didn't you?

[hawker750]

loma has it about right. BOAC you are living in a previous age. If the crew of Kegworth had followed their SOP's and relied on cockpit indications and not on gut instincts that were so terribly wrong then that tragedy would not have happened. The crew of the Citation at Biggin crashed a perfectly flyable aircraft into a house because they went with their gut instincts not what their instruments were telling them. I thought the day had arrived when SOP's are followed based on the known facts not on what might have happened or what might have fallen off. SOP's can not always cover every scenario such as multple failures ( Sioux City and Singapore are just two) Then the passengers have to hope that their crew is a little bit special and not just mister average.

H750 - I think that you have misinterpreted the underlying reasons for both of those accidents.

[BOAC]

Oh dear, we seem to have a rabid dog running here! Please note I have made no comment on the conduct of the crew/SOPs/cockpit indications/gut instincts/Kegworth or any other of your bits. I cannot actually see what relevance any of that has to do with this incident. My comments are merely on the fact that to you, an engine failure and single engine landing on a twin appears to be just 'another regular day at the office' and 'normal'. I'm quite relieved to have experienced a calmer aviation experience. Yes, I would stick to 4 engines with your history..

Does anybody have a bucket of cold water handy?

[Lyman]

So not a bird strike, on the day. The previous goose ingestion was addressed exactly, how? Other than r/r two big cold blades?

So you know it was the same engine involved in both incidents? How?

[Lyman]

Of course not, but failing the data, it beats some version of MIR falling out the sky.....

[lomapaseo]

All points registered and understood

I'm outta here unless somethin new turns up

[Lyman]

The bits came out the back, not the side, boring....

[gas path]

As it happened to go 'bang' I think you may find the failure is further forward than the LPT.

not necessarily true, when the LPT goes, the High compressor still runs, but with a screwed up pressure flow comming into it from a dying LPC. One would have to know what happens to the vane scheduling and surge margin in that case to decide if the bang was primary or late to the LPT.

Really tough to take out a hundred pounds of LPT vanes etc. with an upstream failure in these modern machines.

[gas path]

I'll rephrase it then ! I think you will find it is a little further forward than the LPT.

" the bits came out the back, not the side. Boring"

Actually, there is quite a hole in the side of the engine.
Just the one spot, looks from the picture like it was letting fire out for a bit so should have been downstream of the combustor.

There, that should make it more interesting, Lyman
