rogerbacon Posted June 11, 2009 Posted June 11, 2009 I have a small soft area under the wing along the fusalage on the left side. I guess this is delamination but it is very soft and spongy. How should I go about fixing this and is it a ver yserious concern until it is fixed? Here is a picture I took: http://img132.imageshack.us/img132/2238/imag0063k.jpg Quote
Phil Kriley Posted June 11, 2009 Posted June 11, 2009 A friend has a Vari EZ that has a couple of those on the top of the wing near the fuselage. He said it was a paint blister. If it were me, I'd open up that bubble and see what was under it. If it's just a paint bubble - well, you have a really simple repair. But if its a delam, better to fix it now before it gets any bigger, IMHO. Being under the strake, do you think it might be a fuel tank leak?

Orinoco Posted June 11, 2009 Posted June 11, 2009 That may be a bubble in the paint. I'd suggest puncturing it with an awl to see how thick it is. I doubt if a layer of glass would come up that high in such a small area. Quote

You could do an asperationl biopsy to see what is in the void (stick a large syringe needle into it, pull back on the plunger to see if it is air or liquid. the fact that it is smooth and rounded indicates to me that the top layer, be it glass or paint is being pushed from below by either gas (air or some contamination causing outgassing) or liquid. without personally seeing or touching it, my guess would be that the bubble is between the underlying glass and the paint/primer. If it were mine, I would, using a single edge razor blade (or exacto) cut the top of the bubble off and determine what is happening. if it is just the paint, decontamination and repair should be easy. If not, you will be able to assess what is actually happening and deal with it appropriately Remember, a patient that accepts a free diagnosis and treatment plan usually overpays:irked: Quote I Canardly contain myself!

rogerbacon Posted June 11, 2009 Author Posted June 11, 2009 rog, need more info. did it judt come up? I'm not sure but I think so. I don't remember seeing it before. did you just paint? did you build? No I didn't just paint and I didn't build it.

If not, you will be able to assess what is actually happening and deal with it appropriately Since it is under the fuel tank my concern is that it might be a fuel leaking into the structure. I hope not but I will try the razor blade and see what's in there. Quote

Waiter Posted June 11, 2009 Posted June 11, 2009 Looks to small to be a delam. Like Lynn says, puncture it with a straight pin. Waiter Quote F16 performance on a Piper Cub budget LongEZ, 160hp, MT CS Prop, Downdraft cooling, Full retract visit: www.iflyez.com
