My inspector took advice from the LAA who stated remedial action had to be taken prior to Permit renewal. I decided I could not keep going trough this hassle so took the decision to do one of the torque tube clamping mods. I chose the one offered by Pat Tunney, whose help and assistance was superb, but I think Bob Harrison has also designed a very good mod. It was a swine of a job to do but I am really pleased with the results and after 200 hours there is no sign of any movement. Hope this helps. -------- Gordon Grant G-BWFH Read this topic online here: http://forums.matronics.com/viewtopic.php?p=458119#458119 ________________________________ Message 2 _____________________________________ Time: 01:59:34 AM PST US Subject: Re: Europa-List: Re: Torque Tube enhancement after 400 hours From: kjburns@btinternet.com When building the torque tube up the ream the holes to interference fit ... Or you will get movement . There is an oversize limit to how big you can take the pins if you get it wrong , but custom pins can be oversized (only up to that limit )to save your bacon, any movement built in will increases in service . 300 +hours on reamed / custom pins and no play ....advice taken from Andy Draper UK laa /one of the original Europa production engineers.

About 500hours now since it was done. My Permit Inspector thinks there's a little within-tolerance play, but actually that's the small clearance in the torque tube bearings; I'd rather those bearings had some clearance than being tight, which they can be if not concentrically aligned.
