John,

Thanks for letting me know you also saw what I have seen.  Sometimes I feel
like a voice in the wilderness...  You are number five to watch your gear box
walls move in and out.   Fun, isn't it?  My guess is that there are 95 more
planes out there doing the same thing-I hope the word gets out before someone
has a catastrophic failure.

I moved the flap actuator handle up and down until all the pressure bled off
the system, and was prepared to sop up lots of hyd fluid when I opened the
fittings.  To my surprise, I saw about ten drops, not a gusher.

To disassemble the cylinder itself, drain the fluid, mark the angle of the
fittings with a felt tipped pen, remove the fittings, then push the end of
the cylinder in about 1/4", which allows you to easily remove the C ring.  Be
sure to put the spacer in the cylinder in the correct end to shorten the
stroke in the right direction.

I suggest you fill the hyd cylinder with fluid before you put it back in the
system, as I didnt, and it took a long time for the air to get out of it.

John, I am posting my answers to your letter on the builder's site so that
more people will take this problem seriously, and I won't have to repeat the
disassembly instructions.

Our heartfelt thanks should be given to Bill Maddox for bringing this to our
attention in the first place-I thought I was imagining things until I
remembered that he mentioned it.  Well, at least 5% of the planes have this
problem, maybe it is time for an AD to be issued?
