Tarabocchia > > http:\\hometown.aol.com\Zodiacbuilder Wet wing might sound like an easy way to go, but I've chased enough fuel leaks to know that I wouldn't want to do it on my airplane. You have to get everything REALLY clean before sealing, then I would recommend using solid rivets, not the blind rivets that we like so much. The tanks might leak-check OK at first, but after a little flexing you could find yourself looking at fuel seeping out under your wings. Then you'd be drilling off the skins and starting over. You can't fix a fuel leak in an integral fuel tank from the outside, it has to be stopped from inside the tank. I'd go ahead and weld the tanks or buy them from ZAC and be done with it.

It appears the fold they put on the 'D' of the side of the tank was bent a little sharply, leading to a fatigue fracture.

The tanks in my HDS are pro-sealed intregal tanks. I have about 130 hrs in 2 years with them. Absolutely no problems and they were very easy to build. My only regret was not wetting the wing bay.

Not something I would put on my plane simply because they will be a continual source of aggravation (imho) Don't wish to dampen enthusiasm...and to each his own. But my experience is that wet wings are constructed a lot more solidly than the leading edge of a Zenith. I can see that one solid landing and you could be chasing leaks for a long time to come and may eventually have to fit separate tanks. Bladder tanks suffer from chafing problems and (yes I have worked on airplanes with bladder tanks) and lacing those isn't something one wants to do very often either. Thankfully they are no longer the norm. It would appear to be an ideal solution in many ways...and as "experimental" I have no problem trying something new...but I do wonder about the designer's thoughts on the issue...I'm sure the thought did cross his mind...and yet he designed tanks to fit the space. Has anyone asked Chris about wet wings? I guess on looking at what is suggested my conclusion would be that any part of an integral tank that is capable of being moved (by any means) is not adequate to be an integral tank..period. But then this is just my opinion...fwiw.
