For those of us not covered by the PFA and who have a little difficulty and
cost getting stuff from the UK.
As I understand it the Tailplane mass balance arm broke at the lower strut
where it joins by means of the adjustable connector to the TP torque tube.
The issue is not the cables but the strength (or perhaps more accurately the
fatigue resistance) of the mass balance arm in the face of vertical
stresses.
Could this be solved by simply reinforcing the mass balance arm? For
example by welding a sleeve over the lower tube.
I share Fred's concern that continuous friction and sideways play even if
only 8mm can not be a good situation .in an airplane context.

I can agree there, if one will be able to feel the friction.
Especially if one doesn't fly a lot of hours, it seems the
counterweight will be in a permanent, "frictiony" rust condition. I
would have suggested Teflon, rather than phenolic.
