able to sheath issue. It is a problem with the cable installation, most lik
ely a kinked or bound cable. Maintainers unfamiliar with the Europa often l
ook at the cables and are appalled that they are loose and not firmly bound a
ll along their route to the carb. In their attempt for neatness, they bind t
he cable(s) and cause them to bind. Builders also fail to get their initial
throttle box alignment correct to prevent the cable(s) from cleanly enterin
g the sheath from the throttle arm. I recently scolded one of my clients fo
r allowing a well known Rotax repair facility touch his cable routing. The r
epairman kinked the cables and bound them tightly. It was an older Classic (
20+ years old), so upon installation of his new cables, all worked flawlessl
y again.

ng lubrication are this pivot on the throttle linkage and the box cable pivo
t attachment in my opinion.) Look into the throttle box for proper cable al
ignment. If issues are found, simply removing the cable/throttle box to you
r nice warm workbench and correcting issues is all that is needed. I find t
hat if the cable itself is kinked, or unraveled, it is best to replace the c
ables as it is not worth the time. If the cable will not operate laid out o
n the bench, it won't work in the plane. If you have to tug on a cable in e
ither direction to get it to move, you have a damaged sheath. Remember, cab
le sheaths are just a coil of wire wrapped around a nylon tube. If the wind
ing is damaged, it squeezes the inner liner, and the cable will not operate f
reely in the sheath.

(Although I have used a graphite lube to ease customers fears from the cons
tant complaints of club members/owners on this subject.) The sheath is line
d with nylon, coiled in stainless, then heat shrink over the top making a di
rt resistant sheath for the twisted wire cable. My old original Classic cab
les from 1998 (I'm not sure if they were supplied by Europa) were damaged by
the original builder and were shortened in length, but alas his technique w
as poor as the cable sheaths were bent hard, the cable end cuts were smashed
and the cable attachments were misaligned in the throttle box. So there wa
s much to correct. Note that if supplied with an aftermarket or original no
n lined sheath, they are best replaced as stainless steel to stainless steel
can lead to a corrosion problem eventually. My 2005 supplied Europa cables
have been good now for 15+ years with only a single light lube of a Teflon o
r graphite that was used during inspection (I can't remember what lube I use
d on the cloth as I was more interested in corrosion of the cables here in Fl
orida). The reason I pulled my cables was for an experiment during my rubbe
r replacement at the 10 year condition inspection, when I also chose to inst
all a throttle friction.

Read over the attached paper and check your cables for yourself. Correct a
ny issues, make sure it works on the bench with the cables straight, then ma
ke a large loop and check again. After install in the aircraft but not yet a
ttached to the carb arm, the cables should move freely. If the throttle ca
bles worked on the bench and not in the aircraft, you've pinched something.
I've found from winter to summer, from minus 10C to plus 40C the cables wor
k fine from Canada to Florida so they should work for you.
