Sonex #0525 took to the air May 5, 2005.

The kit was delivered in 2003, which makes the still original canopy almost 12 years old. Now, maybe because of UV-light, ozone, age or whatever, I find that it gets increasingly brittle. This manifests itself in such a way that it starts to crack around the hinge rivet holes on the right side.

Anyone with the same experience? Anything that can be done about it?

Thanks

My original canopy was circa 2007. I installed it 2012. it was already rather brittle and cracked when I overtightened it to the frame. The replacement canopy I purchased in 2013 was much more rubbery. So far, its still crack free and fine. I would expect after as many years as you have seen, that it might get old and brittle like I too have become.
