Control cables for gliders

The Libelles have the same "S" tube adjustment device on their rudder
cables. Because of the wear in adjusting them, they have an AD, a
maintenance requirement, that requires they be inspected and replaced at a
specific time limit. Mine have never shown bad wear, but still get
replaced. On the Libelles, the cables only go to a mechanism behind the
pilot seat, then a long tube transfers the motion back to the rudder in the
tail.

Several years ago, my old 301 was in for "Annual". The IA asked the hours in
the logbook. I said" It was just over 500". He said, "Damn,we will have to
replace the cables since it is written in the book".
So, we pulled them out and they were very bad and would have been a safety
issue for sure.

I thank everyone for the great advice on replacing cables and such. However
my problem lies, not in obtaining the cable, (I can get 1/8" 7x19 cable
locally), but in finding the proper size turn-barrell ends (threaded to go
into the brass adjuster), and the eye-end to attach to structure forward of
the rudder pedals. By measuring the size and thread pitch, they appear to
be different size than what would be considered normal (as in an MS or AN
standard).

The threaded ends and the eye-ends would be swaged onto the cable with a
special tool, and using a Nico-press tool would not work.

So, back to my original question......does anyone know of a source for these
"European" style threaded ends or eye-ends.

Our flying season in still 3 months away so plenty of time to source them
out, but I need help.

Thanks

Mike

Is there room to replace the swaged-on ends with normal eyes
where the cable is attached by threading through the eye,
using a thimble to avoid abrasion of the cable by the eye,
and a Nicopress sleeve to complete the attachment ? In this
case, also see the Aircraft Spruce catalogue for complete
turnbuckle assemblies with a variety of ends.
Alternatively, they also have swageable screwed ends, but
they would probably fit AN or similar barrels only.
Cheers, John G.

I have tried to send you a direct email but each time it has bounced.
Re cables, has the Florida manufacturer of the Krosno (now Peregrine)
changed the desiogn? If not, you can buy what you need from him.

This must have been the original cables. When I replaced the nearly 500 hour
old cables in my 201b they were in perfect condition.

I need to correct my original post. The AD required replacing the original
cables, then inspections every 100 hours of time in service and replacement
as needed.
