I also recall reading that in this particular issue, there have been zero indications of a problem in any of the existing fleet, just engineering recalculations of a potential for a problem. It almost seems to me that it would have been less confusing to all if they had issued two separate SB's for the respective models affected by the respective concerns. -------- Myron Nelson Mesa, AZ Flew May 10 2014 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=456204#456204 ________________________________ Message 2 _____________________________________ Time: 02:31:47 PM PST US Subject: Re: RV10-List: Re: SB From: Tim Olson On VAF, one of the Van's people did comment that they had found the cracking on at least one of the factory demonstrators, and 2 other planes. So this isn't just an engineering recalculation, but something they've observed. I think they're probably just as interested as we are to see the magnitude of the actual problem in numbers of actual airplanes affected.

Don't know details just he already ordered parts to fix. Off subject I found both of my steps cracked. On bottom side of steps,one was cracked 2/3 around the steel not at weld. Looks like it started right at weld.

They make a Teflon core version about $200 each, but you will not have to change them since the internal cores do not melt and become stiff and unmovable. Also add 1-2" to Vans length, better an inch too much than an inch too little depending on your routing. It is a pain to change a cable with the engine in place. Be sure and use the stainless/aluminum fixture to better seal the FF heat out of the cabin. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ________________________________ Message 6 _____________________________________ Time: 04:57:21 PM PST US From: "Carl Froehlich" Subject: RE: RV10-List: cable lengths I still use the Van's cables but I have always run them inside a small diameter fire sleeve where they pass under the engine - same with the alternator and starter cables.

I got silver firesleeve just like you use on hoses. 1/2" fit well over the cable. Sealed the ends with high temp RTV. http://www.myrv14.com/buildlog/20160428/RV14160420-173853-076.jpg Then on Amazon is this 3/4" silver wrap that says it's good for 1000F continuous, and 2000F intermittent if I remember right. The silver does a good job of rejecting the heat. I wish I would have done this on my original RV-10 install.

Have cracks been found there? I am think, based on VAF posts from Scott at Vans, that there were spar web cracks on the 10. However, I am not 100% sure that the cracks were on the 10. I am sure, again based on posts from Scott, that the concern with the aileron brackets is specifically with cracks in the radius of the brackets, not particularly with the rivets. He also said that there had been NO cracks discovered in the aileron brackets on any of the airplanes at this time. Stress Analysis done as part of Van's study of the spar web problem identified the inboard aileron brackets as potential trouble spots. Hence, the inclusion of the aileron brackets in the SB. Finished my inspection today and no problems were found. In fact, everything looks pretty much like new. 2008 and 855 hours. I removed the material as suggested in the SB and will now be able to view the suspect area without taking the ailerons off in the future. -------- David Maib RV-10 #40559 New Smyrna Beach, FL Read this topic online here: http://forums.matronics.com/viewtopic.php?p=456223#456223 ________________________________ Message 9 _____________________________________ Time: 06:46:05 PM PST US Subject: RV10-List: Re: cable lengths From: "Lenny Iszak" Just removed my cables. They are all sticky, but the cover at the end of the mixture cable is melted. The next set will be firesleeved as Tim suggested. Van's cables would have worked just fine if i would have protected them from heat. They used to be nice and smooth for about 20-30 hours.
