Big,

I'm sure all remember early airbus bird, that with the Company Pilot
and Airbus Wheels in it, made a slow low altitude pass over, I forget
just what they were having on the ground,and bird got behind the power
curve and sank into the trees and crashed. Red faces all over Airbus.


I'm sure most remember that was not at all what happened. Red faces all
over Air France when their hot shot demo pilot had a "Hey, watch this"
moment.


And Airbus..

Still a lot of unanswered questions about that accident.

Well, RR engines are crap anyway. I've flown them on two types. They;re
needlessly complicated, labor intensive to maintain and they leak oil

Bertie, by 'cabin', do you mean the portion of the turbine that houses
the vanes?

And the pilot Michel Asseline is still in jail, I hear

No, by "Cabin" I mean the portion of the airplane that the people sit in.

The pressurisation for almost all jets comes form the turbine section.
Several engines, most notoriously, RB211s, leak engine oil into the turbine
section where; it's heated, pyrolised , and then injected in a fine mist
into the cabin where it causes nerve damage to the occupants.
All jet engines do this to some degree or other. RR engines, particularly
the RB211 and particularly the early engines, inject lots and lots of this
into the cabin.
Nice.

It's a huge problem worldwide. It's barely discussed in the US....
The ramifications for the industry if this is ever looked square in the eye
are mindblowing.
Boeing have gone with a seperate blower for the 787 because of this
problem.

Nice.


I don't believe this, in the oh-so-particular aviation industry! Why
hasn't (a) anyone made a noise about it and (b) this affected people
adversely yet?

But if it was really such a problem, and considering that jets have
been around for 40 years now, there should've been a name against
some sort of sickness that this causes.

Quite disturbing, truth to tell. Thanks for the erudition

If I'm not mistaken, and it has been forty some years since I've bent a
wrench on the torch so I may well be, the pressurization comes from the
compressor section and not the turbine section. In particular, my manual
for the JT8D says it comes from the 13th stage compressor. It would be WAY
the hell too hot to come from the turbine section. It is hot enough coming
off the compressor to require an intercooler before using it for
pressurization.

Well, there is some noise being made about it, but not enough.
Governments could fall over theis ( particularly the British one) and it
would devastate the aivaition industry.
It has affected people. Lots of them. Mostly pilots. Lots and lots have
been grounded by exposure to engine oil fumes.

Yeah, sorry, slip of the tongue.Yes, the compresser wsection. Air coming
from the turbine would be marginally worse!

He was originally sentenced to 6 months in jail, and 12 months
probation. He appealed, and the sentence was increased to 10 months
in jail, and 10 months on probation.

He eventually served the full ten months in jail, and has been
released.


Yeah, sounds about right.

i think he was mae a scapegoat, myself.
