champ formers

Post by Richard »

The IA has found some of the lower formers on the champ fuselege have gotten moisture damage and split some of the plies. He thinks I should recover the aircraft and install new formers. Another IA told me, he had the same problem on a champ and was able to install doublers. The a/c was covered only 10 years ago and I'm not in the mood to recover the a/c again.
Any ideas?
Thanks Richard

I have seen formers like that in airplanes that had doublers installed to strengthen them and worked fine.

To tell the truth if there is nothing wrong with the fabric, the last thing I would do is to recover it right now. The fabric is fine and pretty new, while the doubler is showing some distress. Redo the doubler or back it up and keep flying.

Like Joe said.

Add a wood doubler on each side and shoot a couple nails or screws through it.
