I wouldn't want to dispute the seriousness of Garry's oil pipe failure, but
I ran my 914 with Europa supplied original oil pipe in their fire sleeve
according to their route, aiming to give maximum clearance from any hot
bits. It clearly became hard and shiny at the front end within few hours
flying but remained that way without problem until I changed it at 4
yrs/400+hrs. The replacement (Europa/Rotax standard) with a slightly thicker
fire sleeve is going well 100hrs later. Regards, David Joyce, G-XSDJ

Actually, I was one of the earliest 914 Europa drivers in the US.......first
flight being in 1999. With about 50 hours of flight I had the oil return
line "carbonize", and burst in flight. Fortunately, no fire but lots of
smoke. The oil return line provided by Europa (or perhaps it was Rotax),
was junk. I replaced it with a stainless steel braided oil line, covered
the line with firesleave, and further wrapped a stainless steel jacket
around the line where it comes closest to the exhaust system. 400 hours
later, no problem.
A better solution however, is to turn the banjo fitting at the bottom of the
engine so as to face forward. Then route the oil return line forward to the
front of the engine and then backward to the oil tank, keeping the line far
away from any exhaust components. A "stock" oil return line, fitted per
instructions WILL burn up. Please take this advice seriously.

Hi! Gert
Whilst I'm not a 914 "driver" YET.. I seem to remember that there has been
an issue over this problem that involved re-routing the pipe /changing the
direction of the "banjo" fitting to take the hose away from either the
manifold or muffler heat?
I'm all ears for messages from those who have been previously informed.
Regards
Bob Harrison.

Subject: Europa-List: Oil return hose / 914
Hi
I have had an quite unpleasant experience while doing my annual.
The last month or so I have noticed a ( - very week) smell of "hot oil"
sometimes during take of...... and funny enough only during take of.
Could not localize the reason until now when disassembling the different
parts under the cowling for the 100 hours/annual check.
It looks like the oil - return - hose have been more than hot under the
asbestos - fire - sleeve, and therefore have changed to a kind of
"glasslike".
I am sure it would have collapsed within the next hours.
The oil - line have been routed according to Rotax installation manual and
instructions from Europa - app. 90 degree to the stb. side and up alongside
the intake manifold to the top of the oil-tank
The problem is on that piece of the hose that runs between the turbo unit
and the bottom of the engine.
You better put that oil-line on your check - list if you fly behind a 914'
...
FYI - I have never seen higher oil-temp's than 110C (app. 230F) according
to the log in my FlyDat.
Have other had similar experiences?
