American Yankee delam repair?

[alfadog]

I have another little project bringing a dormant airplane back to life. I like doing that. I have like four or five of those projects going right now. This is an American Yankee AA1. Original American Yankee. Prior mechanics had taken the gear off without removing the wings to address some corrosion and was not able to get the gear back on without removing the wings nor were they able to get the wings off. I was able, with the help of the owner whose a pretty decent mechanic himself, to get the wings off, correctly install the gear, and reinstall the wings successfully.

The next thing I'll need to tackle on it will be delamination issues on the trailing edges of flaps and ailerons. Common issue no doubt in these old "Grummans". The original service manual does tell you how to make these repairs and mention Kit 125 or something like that. But I'm curious, since that service manual is almost 50 years old, is there a better way or better adhesives? Does anybody know what would be the latest and greatest for this repair?

Call fletchair,

it’s some glue, don’t over think it, by the time it fails again you’ll probably be dead and the next owner will rinse and repeat, had it happen to a plane I used to fly with a buddy, wasn’t really a big deal.

Great planes BTW

+1 for Fletch Air. My Dad had a hangar at Silver Wings and said it looked like a quality operation.

I don't know what product to advise, but what ever you use I'd do some serious testing prior to making the repair.
Glue some aluminum stripes together see how well the glue works.

You could also try Roscoe Rosche at yankee aviation or Gary Vogt aucountry aviation, both are also Grumman guru’s.

Thanks for the advices on who might know of a better solution than the original. Not to say that the original solution is not a good one, CS3204 fuel tank sealant - readily available and relatively cheap to purchase.
