Hi There All,
Couldn't find any data concerning the replacement of what we call in french "silent-blocks".
Has anyone experienced a problem with these rubbers, how did he
detected it?
Cheers,

| Subject: | rudder cable pull test |
The new inspector for my Europa would like to see the results of a pull test on
my rudder cables.
Has anyone done this in UK, and if so, how did you achieve it?
The main lengths of my cables (back to the Graham Singleton bellcrank on the rear
bulkhead) are made up and installed in the bonded-on fairleads so I'd have
to break something to take them out. Applying 550 lbs tension in-situ without
over-stressing anything else could be tricky.
To apply the pull, I am sure that in the past I've seen lever-operated hand winches
advertised which can (eg) pull out a tree stump but I can't find anything
like that now. Nor can I find spring balances that would read up to about 600
lb for measuring the tension.
Any advice welcome!
in friendship
Rowland

In response to an off-forum reply direct to me, the number comes from the breaking
strain of the cable (920 lbs) and the 60% of ultimate load called up in AC43.13-1B:
"7-146. CABLE PROOF LOADS. Cable terminals and splices should be tested for proper
strength before installation. Gradually apply a test load equal to 60 percent
of the cable-breaking strengths given in table 7-3 and table 7-4, for a period
of 3 minutes".
If I can't find any other UK Europa builder who has done this test, my next port
of call will be LAA Engineering to see if they can offer some suggestions to
my inspector.

I did the LAA Rotax maintenance course ran by Kevin, apart from being slightly
disorganised in terms of hand outs and course notes he proved to have a very broad
knowledge on Rotax. I subsequently had Kevin fit both a water and oil stat
to G-IPOD, both of which greatly improved the cold weather operation of the
aircraft.
I am due a carb check soon and will be asking Kevin to do that a general inspection/service
and also cast an eye over the entire installation for the permit
renewal.

Hi Rowland,
Can I ask, is the inspector interested in your swaging, because if it meets the
swage test, is not asymmetrically pulled up or too stressed over the thimbles,
what actually is he after? If he wants proof that the supporting structures
are strong enough, such as the rear bulkhead that supports the GS mod, is he interested
whether it can withstand the 60 % overload of the designed cable? Anyone
able to calculate the aerodynamic load at VMax rudder control deflection..(used
to know that), and the max load on the pedal, based on mechanical advantages
etc.? Leg pressure must be under 100 lbs, which I base on large aircraft
being a max of 80 lbs as I recall, so it all seems a bit much to expect.
To me, its academic if the swaging is appropriate, the structure of the bulkheads
is well made, and the correct sized cable is used. Is he within his power to
expect such things? Maybe time to change inspectors if you can ;-)
Regards
Tony Renshaw
