Only wish, like everyone else that there was something that I could say to make it go away!! But unfortunately at the moment that is not the case. At least the USA appear to be the leaders in this type of cancer. My thoughts and prayers are with you. Keep your chin up. Kindest Regards Ivan From: owner-europa-list-server@matronics.com [mailto:owner-europa-list-server@matronics.com] On Behalf Of Bud Yerly Sent: 06 October 2012 23:25 Subject: Europa-List: Out of service and missing Rough River I hate to admit I am getting a bit old. I have the been diagnosed with prostate cancer. We should have caught it earlier but that is life. I have been going through biopsies, cat scans, bone scans, and had folks violating my body in new and unusual ways for the last month and have a bit more to do to check all the avenues of spread. I know I could never be a gay person now. Good news is I have great doctors and facilities, good insurance, and have had to learn patience with those who practice medicine. I have learned that health insurance professionals / death board members require more of my attention than the doctors (and I found it difficult not to be cranky with them). My prognosis is full recovery after a few months of discomfort and more tests. I understand that it is difficult to sleep when your groin glows in the dark. We shall see. So you guys lucky enough to be at Rough River, I envy you and will miss an opportunity to bore you to death. Regards, Bud Yerly Don't Archive No virus found in this message.

Sorting out all of the thousands of items with your help would ha ve been welcome. Everything could have been made bullet proof, trouble is the Europa would h ave weighed perhaps 1200 + pounds, with little payload ? A number of options are available to you. 1]. Submit your new [improved] design to L.A.A. you might get it through in a year or two ? 2]. Call Karen at Europa, have your Credit Card ready, and order one of the new [ improved] torque tube assemblies. With hindsight, and less pressure 18 years on, Europa have done a re design on this. Back then, we didn't tak e into account that builders would take it apart / reasemble / take apart / reasemble it the wrong way round / take apart / reassemble and wear the ho les .......... or they would smack the mass balance weights onto the stop.. ... If you take this option, you might have to ream out the bores of the TP 5 /TP6 sleeves in your tailplanes to allow the torque tube to slide on eas ily, as they were matched to each individual torque tube. Easy but time con suming, with a broom handle and emery cloth. Almost certainly you will need to sweat out the TP13 bushes [ the four 1/4' ' bore drive bushes in the inboard rib] and re pot them to match the drive pins, simple job with a heat gun and 1/4'' bolt, and some epoxy. This heavy duty item is, funnily enough, heavier. 3]. Remove the entire torque tube assembly, mark everything as to their ori entation [ horn , drive plates and nylon spacers relative to the torque tub e] and establish the scale of the wear [in the holes, not the pins]. If the pins are the original 1/4'', and the holes are not too worn [ they might b e now if you have been swinging on the tail to check wear] the next size up was 5/16''. Not sure if these are available from Europa, as they go direct ly to 10mm now, bigger is better, but doesn't give you another shot at it i f you mess up on reassembly. The new holes in the tube / fiting need to be an interference fit, as in if you can push the pin in by hand, the jobs bu ggered before you fit them. I have just done this job last week to a monowh eel with 800+ hours on it. very slight play but as it was in my workshop it made sense to sort it for another 800 hours life. Get a machine shop to ream the holes out to 0.007'' smaller than the pins A CTUALLY MEASURE, and make sure you don't lose the relative positions of th e fittings when this is being done. If there is significant play between th e drive plates, ensure they are clocked to be in allignment with each other during the drilling process. DON'T trial fit the pins ! It is a once ony j ob ! On reinstallation, to drive the pins in you will need a 4lb copper ham mer.With the nip of the tube on the pin, it will need a firm wallop to driv e the pins in, should be a '' doink, doink, doink, donk '' Mark with a felt pen on the head of the pins the axis of the split pin hole so you can have them vertical when you insert them, it helps to taper the lead end of the pin back to the split pin hole to assist insertion, and lube the pin with t hin oil. Depending on whether the original builder put the inspection / view panels in the place described in the Build Manual, or chose to delete / move them, this is either a 3 hour each way job + the machining work, or a couple of days marathon swearing session. This work will need inspecting, and entering in the aircrafts Log Book.

I have zero engineering background, and would rather just fly aircraft which is what i have been doing for the past 50 years, However I think it was a poor design and Loctite a poor solution to fix it. I have seen some ingenious clamps LAA approved which i think will solve the problem, and really make the problem go away for good. It may be expensive to have done, but i personally see this as a good engineering solution. I know of a number a failed Loctite cases and the way above is the way i intend to go.
