Subject: [FlyRotary] Jeffco Problem...worst day as a builder

Well, this was the worst builder day I have had. That includes = the day I realized I had to build a new rotary engine, which, btw, was runn= ing better each day before this fuel issue developed.

As the collective from the various list I am on may recall, I have had = persistent fuel leak issues. A few weeks ago I had a visit from the fine me= n of the Ellington/JSC/NASA fire department when I leaked a few gallons on = to the hangar floor while I was at home sleeping late. Also, I thought my o= riginal clear factory tubes failed due to ethanol. They had turned color an= d became brittle (turns out they had not YET leaked.

I tried sucking new Jeffco into where I thought the leak was (very hard= to reach area behind the spar. I found a loose hard point and since I was = having some fuel seep through the floor of my cabin I thought maybe the fue= l was seeping in behind the hard point into the foam to the cabin floor. Si= nce the two hard points from the strake fuel line were both put in per plan= s years ago (before my choice to use a rotary, thus auto fuel) they were in= stalled with EZ-84/flox. Since the flox around the loose hard point seemed = a bit "off" I decided to redo both of them with Jeffco. At the sa= me time I also took out the factory fuel elbow fittings as mentioned above = and installed Vance Atkinson's gages. I did this over the last few days= .

I thought all was well, but when I added fuel to the right strake only,= I still had fuel seeping through the cabin floor. So, I am having fuel lea= k though the inner foam. I spoke with Velocity, Inc who stated I could eith= er go into the inner skin around the stake storage area or cut a hole in th= e top of the strake to find the leak. I chose to go into the top of the str= ake as I thought it would be better to not try to patch a leak from the out= side. So, I cut a hole in the strake to apply Jeffco to try to find/cure th= e leak.

EEEEEEAAAAAKKKKK. I opened up the top right strake and the Jeffco on th= e top of the strake was sitting in the bottom of the tank. OMG!!!!. Almost = all the Jeffco from the top of the strake had fallen off. It was all flaky = and not adhering. Also, a number of places from the sides and bottom had al= so fallen off.

I called Velocity, Inc and they said they had never had this issue befo= re. They suggested I look in the other stake to see if the problem was ther= e too. We discussed when I applied it and how. Now guys and gals, I am not = a complete incompetent. I know I sanded stakes before I applied the Jeffco,= I mixed it well and per instructions. Also, the top strake Jeffco was appl= ied at a different time/batch from the sides/bottom. The Velocity top strak= e is a pre-built piece and is laid on the strake sides/bottom in a separate= step and the Jeffco is applied to the top before you seal it, then you sea= l it with more Jeffco.

I have never had more than about 20 gallons of fuel in the system (abou= t 60 total capacity). I have had the fuel sit in the strakes for a long whi= le though. I used the Jeffco since it is supposed to be more resistant to f= uels like diesel and auto, even with ethanol...at least that was my underst= anding. Some ares of the strakes seem pretty good (but I don't trust an= y of it now). I did get TWO, one gallon kits of Jeffco back when I did this= part of the build. My first thought is that perhaps one of the buckets was= a bad batch. Donno.

I did cut into the pilot strake too. It was not as bad. The top of the = strake looks good, but I do have some flaking on the sides. There are four = compartments in each strake. I cut into one on the co-pilot side, and three= on the pilot side so far. One on the pilot side seems perfect (so far). Th= e inconsistency has me confused currently. But to be honest, after dealing = with this for a while and trying to be philosophical about it...such as I w= ould much rather find it now, I walked away and worked on re-attaching my a= ilerons after balancing them.

So, it seems many of those other fuel issue may have not been t= he problem I thought they were....this does seem to be the cause for when t= he fire department came out as that leak just seem to happen.  When I = pressure tested this system a few years back, all seemed fine.

I am posting the pix on the Canardzone but I am posting this message on= a few sites like FlyRotary and the Velocity Builders site. The factory ask= ed me to post too so they could have a look and determine if this may be a = isolated incident (such as me missing something big) OR if it could be a bi= gger problem. Well, here are some of the pix I took....if they are blurry, = don't worry, it is only my tears......
