WaMooneypilot Posted March 2, 2015 Report Posted March 2, 2015 Hi all, I've searched as for a while and still cannot find how to fix a leak that seeps up through the wing walk next to the cabin. A few people have said it is an easy fix but how do I narrow it down? And how do I get to it? Through the sending unit hole or through the oval port near the leading edge? Ive owned my 62 C for a little over a year and it is truely amazing how much maintenance a guy can put into a fairly simple airplane. sigh. Good thing I love her. thanks!! Joe Quote
N201MKTurbo Posted March 2, 2015 Report Posted March 2, 2015 almost all tank repairs are done from inside the tank. The leak you mention is probably from one of the screws that hold the internal supports under the wing walk. You can probably fix it by removing the screw and coating the head with sealant and screwing it back in. Quote
WaMooneypilot Posted March 2, 2015 Author Report Posted March 2, 2015 Thanks! I'll take a look. Quote
DonMuncy Posted March 2, 2015 Report Posted March 2, 2015 Scrape down through the wing walk material in the center of the "seep" spot. You will find a screw head. Remove the screw and put sealer on the threads. Re-install and dab new wing walk goo over the screw. 1 Quote
carl Posted March 2, 2015 Report Posted March 2, 2015 there is a topic Seal tanks in the vintage section . lance casper gave a good answer on how it is repaired . Quote

Wesley brown Posted March 4, 2015 Report Posted March 4, 2015 I have done the same thing with my grumman. My family never complained they just made the statement that they knew where I was:) leaks can be a pain I had done my grumman three times before it was finally done right. I guess you can say I am experienced. My friend as well with mooneys! He's fixed two leaking tanks. Grumman's are much harder to deal with! 1 Quote
WaMooneypilot Posted March 4, 2015 Author Report Posted March 4, 2015 Hopefully this will it for maintenance for a month or so. The weather here in washington has been very VFR and its killing me not to fly. Thanks for help fellas. Quote
Hank Posted March 4, 2015 Report Posted March 4, 2015 If this doesn't do it and you're tired of messing with it, there's a Mooney Service Center in Troutdale, OR. Can't remember the name, but google should pop it right up if no one beats you to it. Good luck! I had my tanks stripped and resealed in 2010. Quote
RobertGary1 Posted March 10, 2015 Report Posted March 10, 2015 There is no internal tank so if its leaking up through the wing walk that's the source of the leak. There is nothing for it to run down from at that location other than running down the top of the wing, which would be really obvious. It's probably leaking through a worn rivet. Solution is usually simple. Remove the rivet and put it back in with a bit of sealant. The fact that its on the wing walk does make it more difficult. You'll need to remove the material around it and then paint on new wing walk material. If your wing walk is coming up other places its probably a good time to strip it off and paint new on. -Robert Quote
Yetti Posted March 12, 2015 Report Posted March 12, 2015 Don Maxwell article... says permetex 2 for screw leaks Quote
fantom Posted March 13, 2015 Report Posted March 13, 2015 Don Maxwell article... says permetex 2 for screw leaks Exactly. New screw and a Tinnerman Washer....no more upper wing walk fuel seepage. Not fueling the wing to the very top when you leave the plane will also help. Quote
carl Posted March 15, 2015 Report Posted March 15, 2015 I don't fuel the right tank full , and that stopped the seepage. But if I seal the screws do I do it while there is fuel in the tank or should i drain it? Quote
carl Posted March 15, 2015 Report Posted March 15, 2015 Also looking for A&P who will work with me . I am in altoona Pa Quote
carusoam Posted March 15, 2015 Report Posted March 15, 2015 Like glue. Clean, dry surfaces work best. Being warm helps as well... Best regards, -a- Quote
DonMuncy Posted March 15, 2015 Report Posted March 15, 2015 You don't have to worry about draining the tank. It will have leaked out enough to have left the threads dry; and that fuel leaking out cleaned them pretty well. Quote
RobertGary1 Posted March 15, 2015 Report Posted March 15, 2015 I wouldn't recommend flying on an empty tank if that is what you are considering. The seals on the tank selector may not be perfect and could suck in air. This was wisdom I got from Lake Aero after one of their customers had an off field landing. Tank sealing is a perfect owner job. It doesn't take a lot of skill (just be super careful not to plug the rib holes) and is very time consuming. So you can save a lot of money. -Robert Quote
